Most fresh tomato tarts turn into a soggy mess. You slice up the best tomatoes of the season, you build something beautiful, and forty minutes later the bottom is wet and the whole thing collapses when you pick it up.
These do not do that. They are freeform, they are handheld, and the bottom stays crisp all the way through. The base is a sourdough discard pie crust with real layers in it, the filling is blended cottage cheese instead of the ricotta almost every tomato galette calls for, and the top is nothing but heirloom tomatoes doing what heirloom tomatoes do in August.
If you do not keep a starter, there is a classic version of the crust in the recipe card that skips the discard entirely. Same technique, same layers, same result.

Why These Work
The problem with a fresh tomato tart is water. A ripe heirloom is mostly liquid, and the second it hits heat it lets all of that go. In a tart pan you have sides to contain it. In a freeform galette you have nothing, which is why so many of them slump and leak.
Three things fix it here, and none of them are complicated.
The tomatoes get salted and drained before they ever touch the dough. Twenty minutes on a rack pulls out a surprising amount of liquid. This is not optional and it is not a step to shorten.
The filling is thick enough to act as a barrier. Blended cottage cheese with parmesan and egg yolk sets into a firm band in the oven instead of running.
The pan goes in the oven empty first. A screaming hot sheet pan under the crust sets the bottom before the tomatoes have a chance to do any damage.
The result holds together in one hand. I have the photos to prove it.
If you want to skip straight to the amounts, the recipe card is at the bottom of this post.
Why Cottage Cheese Instead of Ricotta
Nearly every tomato galette you will find uses ricotta. It is the default, and it works. So why swap it.
Texture, mostly. Blended cottage cheese comes out creamy and smooth with a little more tang and a little more body than ricotta. Under sliced tomatoes it sets into a firmer band, which matters when there is no tart pan holding anything in.
And it is what is already in your fridge. Ricotta is a thing you buy for a specific recipe. Cottage cheese is a staple in most kitchens now.
It also brings protein along for the ride. Each galette lands around 21 grams, between the cottage cheese, the parmesan in both layers, the egg yolks, and the flour in the crust. I am not going to pretend a butter crust is health food, but it is a lot more substantial than the number you would expect from something this size.
If you would rather use ricotta, it works perfectly. Swap it one for one by weight and skip the draining step.
Ingredient Notes
Full amounts are in the recipe card at the bottom of this post. These are the notes on what to buy and why it matters.
Flour. All purpose or bread flour both work. I tested this batch with bread flour because it was what I had, and the crust came out beautifully. Bread flour drinks up a little more liquid and gives you a slightly sturdier crust, which is arguably a feature when you are building something freeform that has to hold a wet filling. All purpose will give you a marginally more tender bite. Use what is in your pantry.
Sourdough discard. Straight from the fridge, cold. Discard from a well fed starter is best but this recipe is forgiving. Thick, stiff discard works fine here because of how it gets mixed.
Butter. Cold, cut into cubes. Cold is doing the heavy lifting for texture. If your kitchen is warm, cube it and put it back in the fridge until the moment you need it.
Cottage cheese. Either 2% or 4% works. I have made these with both. The 4% blends a little richer and the 2% is slightly looser going into the oven, but the egg yolks set both of them into the same firm band. If your brand has standing whey in the tub, drain it. Good Culture is thick enough that it usually needs nothing.
Parmesan. Grated, and you want it in two places. Some goes into the filling and a little more goes on top of the filling before the tomatoes, where it works as a dry barrier and adds a savory layer without covering up the tomatoes.
Heirloom tomatoes. Whatever is best at your market. See the tomato section below for how to slice and prep them.
Fresh basil. Some in the filling, more torn over the top after baking. Baked basil goes dark and disappears. Fresh basil on a hot tart is the whole point.
What Makes This Crust Work
The measured steps are in the recipe card at the bottom. This section is the reasoning behind them, because a pie crust is one of those things where understanding what each step is doing is the difference between following a recipe once and being able to make it forever.
If you have ever had a crust come out tough, or dense, or flat instead of flaky, the answer is almost always in one of the six things below.
Why you thin the discard first
Thick discard has to be worked hard to distribute through flour and butter, and that working is exactly what develops gluten and makes crust tough. Whisking it with the cold water first means it disperses in a fraction of the strokes.
This is the step people skip, and it is the one that quietly decides whether your crust is tender or chewy.
Why the butter stays in flat pieces
You are looking for flat, coin sized flakes. Not crumbs. Not sand. Flat pieces you can still see.
Those flat pieces are what become the layers. In the oven they melt and release steam, and that steam pushes the dough apart into sheets. If you work them down into uniform crumbs there is nothing left to make layers with, and you have made a shortbread instead of a pie crust.
A pastry blender gives you the most control here.
Can you use a food processor? Yes, and if you are short on time, do it. Your crust will not be quite as flaky, because the processor breaks the butter down more evenly and you lose some of those flat sheets. Watch your liquid closely, since it incorporates differently and you will likely need less than you think. Add it in short pulses and stop the second it starts to clump. My sourdough pop tart bars post walks through the food processor method in more detail.
Why you hold back some of the liquid
Every flour absorbs differently and every starter sits at a different hydration. A fixed number will never be right for everybody, which is why the card tells you to hold back about two tablespoons and add it only if you need it.
Use your eyes. At this stage the dough should look shaggy and underdone, with dry patches still showing. It will look like it needs more liquid than it does. Trust that it does not, because the folding is about to bring all of it together.
Why the fold works like wrapping a present
Pat the shaggy mass into a rough disc. Fold the right side in toward the center, then the left side over that, so you have essentially folded it into thirds. Then fold the top down over that and the bottom up over that. Pat it back out with your hands or the rolling pin, and do the whole sequence two or three more times.
This is a lamination fold, and it is doing two jobs at once. It brings the dry crumbs into the mass without any kneading, and it stacks the butter into sheets that run through the whole dough. Gather the loose bits from around the edges and tuck them into the center as you go. Every one of them gets absorbed and nothing gets wasted.
A bench scraper is the right tool. Use it to gather the crumbs in, lift and fold the mass over, and scrape the counter clean between turns. Your hands will warm the butter. The scraper will not.
Stop as soon as it comes together. You are not kneading. The goal is for the dry bits to be folded in and the mass to hold, nothing more. Every extra fold past that point costs you flakiness.
By the last fold you should see visible seams along the side of the slab. When you cut one of these galettes in half later, those seams are the layers you see in the folded edge.
Why you portion before chilling, not after
Do not save this for later. Weigh the dough out into six equal portions while it is still soft enough to cooperate.
Dividing a firm chilled slab is genuinely harder, and this is your only chance to fix an uneven portion. If one comes up light, press a stray piece into it and shape it back into a disc. Once the dough is cold, that piece will not stick.
Handle each one as little as possible. By this point the dough has been out on the counter through several folds and your hands have warmed it. Shape it into a disc and stop. This is not the moment to smooth anything out.
Why the rest is exactly ten minutes
This window is narrower than people expect, so set a timer.
Straight from the fridge the dough cracks when you roll it. Past ten minutes the butter softens and you lose the layers you just spent all that folding to build. Pull two or three portions at a time and leave the rest in the fridge while you work.
Keep a ruler on the counter for the first one or two rounds. Seven inches is smaller than it feels, and the border math depends on it.
Choosing and Prepping Your Tomatoes
Slice large heirlooms at a quarter inch. Thinner and they collapse and vanish into the filling. Thicker and they hold too much water and stay raw in the middle.
Cut the slices to about four inches so they sit cleanly inside the border. Exact quantities are in the recipe card. A round cutter does this in one motion. Do this before you salt them, because clean cuts are much easier on a firm slice than a limp one. Save the trimmings for the side.
Use a rack, not paper towels. Lay the slices in a single layer on a wire rack set over a sheet pan and salt both sides. The liquid drips away completely instead of sitting underneath. If paper towels are all you have, swap them halfway through.
Do not rinse them afterward. Rinsing washes off the seasoning and rewets the surface, which undoes the entire point. Just blot the tops dry.
Cherry tomatoes get halved lengthwise and go on cut side up. They need less draining time than the big slices, since there is less flesh to give up. I used Bumblebee Sunrise and they hold their shape much better than a large slice does.
Play with the color
This is the part that makes these fun. Pineapple heirlooms bake into a glowing golden orange shot through with streaks of red, and they are some of the sweetest, least acidic tomatoes of the whole season. The Bumblebee Sunrise cherries hold their striping right through the oven.
Because you are working with one galette at a time, every single one can look different. Center a dark red heirloom in a ring of gold. Fan overlapping slices in concentric circles. Lay a solid golden round edge to edge. Ring the outside with halved cherries.
Mixing varieties within a single galette gives you the most striking result, and it takes about thirty extra seconds. Six galettes, six designs, one tray.
Two Ways to Finish the Edge
Both are good and they photograph completely differently. Pick one, or do half the batch each way.
The rustic edge
Fill the round first, then fold the border up and let it gather where it wants to. Loose, irregular, uneven. It looks like it came out of somebody’s actual kitchen, because it did.
This is the faster of the two and it is very forgiving. If your round came out a little lopsided, the rustic fold hides it.
The fancy edge
This is the one I keep going back to, and it is easier than it looks.
- Set a four inch round cutter or ring mold in the center of your rolled round and press lightly to score a circle. That scored line is your filling boundary, and it leaves you a border of about an inch and a half.
- Cut straight slits from the outer edge of the dough in toward the scored line, all the way around, spaced about an inch apart. You are making a ring of tabs.
- Brush the border with a little egg wash before you fold anything. This is the step that makes the whole thing work. The tabs need something tacky to grab onto, and without it they will not stay put.
- Fill the center and top with tomato. You can lift the cutter out now, or leave it in place while you fold and pull it once the border is set. Either works, do whichever feels steadier to you.
- Fold each tab up and over, one at a time, laying each one against the last so they overlap in the same direction all the way around.
- Seal the border. Go back around the outside and lift the edge to about a forty five degree angle, then press in and down against the filling. Up, then down. You are not flattening it, you are just making sure every tab is locked to the one beside it and to the filling underneath.
- Egg wash the outside of the finished border, gently, right before it goes in the oven.
Do not skip the seal. That press is what turns a ring of loose tabs into an actual wall. It closes the gaps where filling would otherwise leak out, and it gives the border something to brace against so it does not relax outward in the oven. Firm pressure, but stop well short of squishing it flat. You want the height.
No four inch cutter? Anything round and about four inches across will do. A wide mouth mason jar lid, a small bowl, a ramekin, a biscuit cutter, the rim of a drinking glass. You are only scoring a guide line, so it does not need to cut cleanly. It just needs to be the right size and to leave a mark you can see.
You end up with a scalloped, uniform border that reads like it came out of a bakery case. Because the tabs are cut rather than gathered, the dough does not bunch up and the border stays an even thickness the whole way around.
The parmesan edge
OPTIONAL! Press finely grated parmesan onto the folded edge before baking, then run the galettes under the broiler for a minute at the end. The edge blisters and browns deeply and the whole thing tastes more like a savory pizza. It is a different animal from the lighter tarts, so decide which one you want before you commit.
Tips for Success
- Cold butter, cold discard, cold water. All three. If your kitchen runs warm, chill the mixing bowl too.
- Stop mixing before you think you should. Both the dough and the filling.
- Weigh your dough portions before they go in the fridge. Eyeballing gives you six galettes of six different thicknesses and they will not bake evenly.
- Ten minutes of resting, and set a timer.
- Preheat the pan. If you take one thing from this whole post, take this one. A hot sheet pan under the crust is doing more work against a soggy bottom than anything else in the recipe.
- Assemble on parchment squares. Build each galette on its own square and transfer the whole thing. Moving a bare assembled galette means stretching and tearing. Cut the squares close to the size of the tart so the corners do not curl in the oven.
- You need far less egg wash than you think. Half an egg yolk and half a tablespoon of milk covers all six, and that includes the pass you brush on the border before folding the fancy edge. Wipe any that pools in the creases, or it bakes into shiny yellow patches.
- Bake to color, not to the clock. There is no sugar in this dough, so it browns slowly. Pale means underbaked.
- Salt the tomatoes even if you are in a hurry. Especially if you are in a hurry.
- Save most of the basil for the end.
- Make the dough and the filling the night before. This is the single easiest way to make these feel effortless. Both hold overnight and both are better for it.
Storage and Freezing
Making them the night before. This is how I would do it every time. Mix the dough and blend the filling the evening before, cover both, and refrigerate. The dough gets its long chill and the filling firms up while it sits. The next day all that is left is slicing tomatoes, rolling, and assembling, and the whole thing comes together fast.
Room temperature. Best the day they are made. They hold well for a few hours on the counter, which makes them good for a party.
Refrigerator. Up to three days in an airtight container. The crust softens, so reheat at 350F for eight to ten minutes to bring it back.
Freezing the dough. The dough freezes beautifully. Wrap the portioned discs individually and freeze up to three months. Thaw overnight in the fridge, then rest ten minutes before rolling.
Freezing assembled galettes. I would not. The tomatoes turn to water on thawing and you undo everything.
Substitutions
Ricotta instead of cottage cheese. Works, and it is what most tomato galette recipes use. You lose some of the protein but it is thicker to start with. Skip the draining step entirely.
2% or 4% cottage cheese. Both work. The 2% goes in a little looser and the 4% blends richer, but they bake to the same set filling.
Romano instead of parmesan. Sharper and drier, and it browns in specks instead of melting into a sheet. Pull back on the salt, romano is noticeably saltier.
Other herbs. Thyme and oregano both work. Chives are good in the filling.
Other vegetables. Roasted zucchini or caramelized onion under the tomatoes is very good. Anything wet needs the same salting and draining treatment.
No sourdough starter. The recipe card has a classic version of the crust with no discard at all. Same folding method, same rest, same everything downstream.
Frequently Asked Questions
Can I use ricotta instead of cottage cheese?
Yes, and plenty of people will prefer it. Swap it one for one by weight, skip the draining step, and everything else stays exactly the same. Whole milk ricotta is the closest match. You lose a little protein and gain a slightly softer set.
Can I make one large galette instead of six small ones?
Yes. Roll the whole batch to about a fourteen inch round, leave a two inch border, and bake for thirty five to forty five minutes. Watch the center, a large one takes noticeably longer to set underneath.
Do I have to use a preheated pan?
You do not have to, but it is the single biggest thing standing between you and a wet bottom. If you skip it, add five minutes to the bake and expect a softer base.
Can I use active starter instead of discard?
Yes. There is no rise happening here, so the state of your starter does not matter much. Cold is what matters.
My filling looked runny going into the oven. Did I ruin it?
Almost certainly not. This filling looks loose in the bowl and sets into a firm band once the egg yolks hit heat. Resist the urge to thicken it.
Why is my crust pale?
There is no sugar in this dough. It browns slowly. Egg wash generously and give it the full time, and do not judge doneness before twenty minutes.
Can I use bread flour?
Yes. I tested this batch with bread flour and it was excellent. It absorbs a bit more liquid and gives a slightly sturdier crust, which suits a freeform tart. All purpose is a touch more tender. Either one is fine.
Does the cottage cheese need to be full fat?
No. Both 2% and 4% work. The 2% is slightly looser going in and sets up the same.
Can I make the dough ahead?
Yes, up to two days in the fridge or three months in the freezer. Making both the dough and the filling the night before is honestly the best way to run this recipe.
What tomatoes are best?
Any ripe heirloom. For flavor, whatever is best that week. For looks, mix a dark red variety in with the yellows and oranges.

- cherry tomatoes optional (about 1 cup)
- 36 g finely shredded parmesan 6 tablespoons, 1 per galette
- 1/2 large egg yolk
- 7 g whole milk 1/2 tablespoon
- flaky salt and torn fresh basil to finish
Instructions
Make the Crust
- Whisk the cold water into the cold sourdough discard until smooth and pourable.
- Cut the cold cubed butter into the flour and salt until you have flat, coin sized flakes. Stop while you can still see distinct pieces of butter.
- Set aside about 2 tablespoons of the thinned discard. Pour the rest over the flour and butter.
- Mix just until the dough comes together in a rough, shaggy mass with dry patches still visible. Add the reserved liquid a little at a time only if it will not gather.
- Turn the dough out onto the counter and pat it into a rough disc.
- Fold the right side in toward the center, then the left side over that. Fold the top down over that, then the bottom up over that.
- Pat the dough back out and repeat the fold 2 to 3 more times, tucking in any loose crumbs from the counter, until it holds together. Stop as soon as it does.
- Weigh the dough and divide it into 6 equal portions, about 144g each. Shape each into a disc, handling as little as possible.
- Wrap the discs individually and refrigerate at least 2 hours or up to 2 days.
Prep the Tomatoes and Filling
- Slice the heirloom tomatoes 1/4 inch thick and cut them to about 4 inch rounds. Halve any cherry tomatoes lengthwise.
- Lay everything in a single layer on a wire rack set over a sheet pan and salt both sides.
- Drain the large slices 20 to 30 minutes and the cherry tomatoes 10 minutes, then blot the tops dry. Do not rinse.
- Blend the cottage cheese, parmesan, egg yolks, garlic powder, basil, salt, and pepper until just smooth. Do not over blend.
- Taste and adjust the salt, then refrigerate until you are ready to assemble.
- Whisk the half egg yolk and the milk together for the egg wash.
- Place a rack in the lower third of the oven, set a rimmed sheet pan on it, and preheat to 425F for at least 20 minutes.
Assemble: The Fancy Edge
- Pull 2 or 3 dough portions from the fridge and rest them at room temperature 10 minutes, no longer.
- Roll each portion to about 7 inches on its own square of parchment.
- Set the 4 inch cutter in the center of the round and press lightly to score a circle. This is your filling boundary and it leaves a border of about an inch and a half.
- Cut straight slits from the outer edge of the dough in toward the scored line, all the way around, spaced about an inch apart. You are making a ring of tabs.
- Brush the border with egg wash. The tabs need something tacky to grip or they will not stay folded.
- Spread 64g of filling inside the scored circle, then scatter 1 tablespoon of shredded parmesan over the filling.
- Fold each tab up and over, one at a time, laying each one against the last so they all overlap in the same direction. FUll video instruction on the blog
- Arrange the tomatoes on top. Lift the cutter out now if you left it in place.
- Go back around the outside and lift the edge to about 45 degrees, then press in and down against the filling to seal it. Do not flatten it.
- Brush the outside of the border with egg wash and wipe away any that pools in the creases.
- Slide the parchment onto the preheated sheet pan. Repeat with the remaining portions, keeping baked galettes and unused dough in the fridge until you get to it.
Assemble: The Rustic Edge
- Pull 2 or 3 dough portions from the fridge and rest them at room temperature 10 minutes, no longer.
- Roll each portion to about 7 inches on its own square of parchment.
- Spread 64g of filling in the center, leaving a bare border of about an inch and a half.
- Scatter 1 tablespoon of shredded parmesan over the filling, then arrange the tomatoes on top.
- Fold the border up over the edge of the filling, letting it gather and pleat naturally as you work around the circle.
- Brush the folded edge with egg wash and wipe away any that pools in the creases.
- Slide the parchment onto the preheated sheet pan. Repeat with the remaining portions, keeping unused dough in the fridge until you get to it.
Bake
- Bake at 425F for 20 to 25 minutes, until the crust is deeply golden and the filling is set.
- Watch the edge from 18 minutes and tent it loosely with foil if it colors ahead of the base.
- Finish with flaky salt and torn fresh basil straight out of the oven. Serve warm or at room temperature.
