This cheddar everything bagel swirl sourdough bread started as a spinoff of my cinnamon swirl sourdough, so if you have been around here for that one, this is going to feel familiar. That loaf came about because I changed my mind about the flavor after my dough had already finished its cold proof, and I turned a plain loaf into a swirl bread at the very last minute. It worked so well that I could not stop thinking about what else the method could do. If it worked for something sweet, surely it could work for something savory.
So I went for the most obvious crowd pleaser I could think of. Cheddar and everything bagel seasoning. Because who does not love cheese.
Here is the honest part. It took me three tries to get this right, and the failures taught me everything. My first two attempts used shredded cheddar, and both times the cheese melted, pooled, and left big hollow tunnels running through the loaf. It tasted absolutely incredible, but it did not hold together. The swirl I was chasing kept turning into caverns and where it did show up the color wasn’t very dramatic. What finally cracked it was switching from shredded cheese to cheddar cheese powder, and the difference was night and day. The powder gives you all the sharp cheddar flavor without any of the melting and pooling, so the swirl stays clean and vibrantly defined in every slice.

Why This Method Works
Most swirl breads ask you to roll the dough into a rectangle, spread the filling across it, and roll it into a log before the final proof. This method skips all of that. You start with a plain sourdough loaf that has already finished its final cold proof, and you add the filling right before baking.
Because the loaf is cold and firm from the fridge, it holds its shape while you cut into it, fill it, and roll it back up. You slice the cold loaf, open up the interior with kitchen scissors, tuck the filling down into all of those cuts, and gently roll the whole thing into a log. The filling ends up distributed throughout the crumb rather than wrapped in a single spiral.
The cold proof is doing the heavy lifting here. A loaf straight from the refrigerator is firm enough to handle without collapsing. A room temperature loaf would be far too slack.

What Two Failed Loaves Taught Me
I did not get this right on the first try, or the second. Both early attempts used shredded cheddar, and I want to walk through what went wrong, because it is the whole reason the final version works.
The first loaf, I packed with cheese. Cups of it, tucked into every cut and piled on top. More cheese sounds like a better bread, but it was not. Cheese behaves very differently from cinnamon sugar. Sugar mostly stays where you put it and bakes into the crumb. Shredded cheese melts completely, liquefies, runs, and pools. As the bread set around those pools, the cheese left behind large hollow tunnels. It tasted amazing and looked like a cave system.
For the second loaf, I cut the cheese way back and even tossed it in a little cornstarch to help it melt more cohesively. It was better, and the loaf held its shape, but it still tunneled. That told me something important. It was not just the amount of cheese. It was the cheese itself. Any melting cheese, however little, wants to liquefy and leave a void where it sat.
So for the third loaf I stopped fighting the melt and removed it from the equation entirely by switching to cheddar cheese powder. That was the fix. No melting, no pooling, no tunnels, just a clean cheddar swirl running through every slice.

Why Cheese Powder Is the Secret
Cheddar cheese powder is the ingredient that makes this loaf work, and it solves the problem at the root. Shredded cheese fails in a swirl because it melts into liquid and runs, leaving holes behind. Cheese powder never does that. It is dry, so it behaves exactly like the cinnamon sugar in my sweet version. It stays where you put it, bakes into the crumb, and hydrates from the dough’s own moisture into a defined cheddar layer rather than a molten puddle.
The result is the best of both worlds. You get real, sharp cheddar flavor in every bite, plus a swirl that actually holds its shape and photographs beautifully. No cornstarch needed, because there is no melting cheese to manage. Plus it gives you a vibrant swirl where ever it lands in the loaf, verses shredded cheese which can melt and absorb and disappear.
Look for a cheese powder where cheddar cheese is the first ingredient, rather than a cheese sauce mix padded out with a lot of starch and filler. A cheese forward powder gives you the truest flavor.

The Cheddar and Everything Bagel Filling
The filling could not be simpler. It is just cheddar cheese powder and everything bagel seasoning, tossed together as a dry blend and sprinkled into the cuts. No cornstarch, no fresh cheese, nothing to melt or weep.
A little cheese powder goes a long way, since it is concentrated and potent. You do not need much to get bold cheddar flavor in every slice. The everything bagel seasoning brings the garlic, onion, and toasty seeds that make this taste like your favorite bagel in loaf form, and because it is dry it distributes beautifully through the swirl and stays exactly where you place it.
The one thing that matters most is how you apply it, which I cover in the tips below. The exact amounts and conversions live in the recipe card.

Why the Double Pan Method Matters
Baking this loaf with a second pan inverted on top as a lid gives it both lift and a clean crust. The covered pan traps the steam the dough releases, which keeps the surface soft long enough for the loaf to spring up before the crust sets.
I bake this in a 10 by 5 inch or a 9 by 5 USA loaf pan with a second pan inverted over the top. After the first stretch of baking with the lid on, I remove the top pan, score one line down the center, replace the lid, and continue baking before finishing with the lid off for color. That final uncovered stretch is what crisps the crust and gives it that deep golden color.
Because the filling is cheese powder rather than fresh cheese, you do not have to worry about it burning or running out of the loaf the way shredded cheese would. It bakes right into the crumb, which is exactly why this version works so well.

Ingredient Notes
This loaf is built on the same short ingredient list as a classic sourdough, with a savory dry filling added at the end. A few things worth knowing:
Active sourdough starter gives the loaf its rise and its long, slow fermentation. If you need to build or revive yours, my sourdough starter guide walks through it.
Bread flour in the 11 to 13 percent protein range gives the structure that lets the crumb stay open and hold up to handling after the cold proof.
Cheddar cheese powder is the star and the secret. It delivers sharp cheddar flavor without melting, so the swirl stays clean. Choose one with cheddar cheese as the first ingredient. Cheese powder brands vary, so check labels for allergen and cross contamination information.
Everything bagel seasoning brings the classic bagel flavor. The full amounts and conversions are in the recipe card.

How to Turn a Plain Loaf Into a Savory Swirl Loaf

The full step by step is in the recipe card below, but there is one detail worth understanding before you start, because it is what keeps your loaf looking clean and professional. And if you need a more thorough guide, Check out my blog post on the Easiest Sourdough Bread Recipe
Normally you would tip the dough out of the banneton onto parchment and bake it as is, with the smooth side facing up. For this recipe you want to do all of your cutting on the bottom of the loaf, not the pretty top, so that smooth top stays intact.
The easiest way to do that is to tip the dough out of the banneton onto your parchment, then flip it back over so the smooth side is facing up again. Now the smooth top is where it should be, and the rougher bottom is facing down toward your work surface. That bottom is the side you cut into.

Working from the bottom keeps the smooth top taut and clean, so it holds its shape, scores neatly, and bakes up beautiful. From there you cut the loaf into sections, sprinkle the everything bagel seasoning and then the cheese powder down into the openings, roll it up, and bake. The recipe card walks you through each step.
Recipe
Cheddar Everything Bagel Swirl Sourdough Bread
Equipment
- Digital Kitchen Scale
- Banneton or proofing basket
- Two 10 by 5 inch loaf pans or two 9 by 5 loaf pans
- Parchment paper
- Kitchen scissors
- Bread lame
- Instant read thermometer
Ingredients
For the Sourdough Loaf
- 75 grams active sourdough starter 1/3 cup
- 350 grams room temperature filtered water 1 1/2 cups
- 500 grams bread flour 4 cups
- 10 grams salt 1 3/4 teaspoons
For the Savory Swirl Filling
- 2 tablespoons cheddar cheese powder 15 to 20 grams
- 1 tablespoon everything bagel seasoning about 15 grams, plus more or less to taste
Instructions
- Mix the flour, starter, and water together until a rough, shaggy dough forms. Cover and let rest for 1 hour.
- Add the salt using wet hands, working it into the dough until fully incorporated.
- Perform stretch and folds every hour for 3 hours, then let the dough bulk ferment covered at room temperature until it has increased in size by 50 to 70 percent and jiggles when gently shaken.
- Lightly flour your work surface, turn the dough out, and pre shape it into a round. Let it rest seam side down for 20 to 30 minutes.
- Shape the dough into a boule, place it seam side up in a banneton, and cover. Cold proof in the refrigerator for 8 to 12 hours.
- When you are ready to bake, tip the cold loaf out of the banneton onto your hand or a square of parchment, then flip it back over onto a piece of parchment, so the smooth side faces up and the rougher bottom faces down toward your work surface. You will cut into the bottom so the smooth top stays intact.
- Slice down through the loaf, three times, then go back through those slices with kitchen scissors to cut them into sections, opening up the interior.

- Sprinkle the everything bagel seasoning down into the cuts first, then dust the cheddar cheese powder over it. Spread the powder thin and even, with no deep pockets in any one spot.

- Starting at one end, gently roll the loaf up into a log, taking care not to deflate it. But make sure its snug. Tuck the end underneath to seal.
- Set the rolled loaf on parchment and lower it into a parchment lined 10 by 5 inch loaf pan. Place a second loaf pan upside down on top to create a mini Dutch oven.

- Bake at 450 degrees Fahrenheit for 9 minutes with the lid on.
- Remove from the oven, take off the top pan, and score one line down the center of the loaf. Replace the lid and bake for 25-30 minutes.
- Remove the lid and bake for a final 10 minutes, or until the internal temperature reaches 190 degrees Fahrenheit.
- Let the loaf cool for 3 to 4 hours before slicing.
Notes
Tips for the Best Cheese Swirl
Use cheese powder, not shredded cheese. This is the single most important tip and the whole secret to this loaf. Shredded cheese melts and tunnels. Cheese powder stays put and bakes into a clean swirl.
Apply the everything bagel first, then the cheese powder. Layering the seasoning into the cuts first, then dusting the cheese powder over it, gives the most even swirl.
Spread the cheese powder thin and even. Do not leave deep pockets of powder in any one spot. A thin, even layer through all the cuts gives you a defined swirl in every slice.
Do not overdo the powder. It is concentrated and potent, so a modest amount delivers plenty of sharp cheddar flavor.
Work with cold dough. Straight from the cold proof, the loaf is firm and easy to cut, fill, and roll without deflating.
How to Serve and Store
This bread is made for toasting. A slice toasted with butter, or grilled into the best grilled cheese you have ever had, is hard to beat. It also makes an incredible base for a savory breakfast, piled with eggs or used for a next level sandwich.
Store the cooled loaf at room temperature in a bread bag or wrapped well for three to four days. For longer storage, slice it first and freeze the slices, then toast straight from frozen whenever you want one.

Frequently Asked Questions
Why did my cheese leave holes in the bread?
Shredded cheese is almost always the cause. It melts, pools, and runs, leaving hollow tunnels behind as the bread sets. The fix is to use cheddar cheese powder instead. Because it is dry, it never melts into a puddle, so the swirl stays clean and defined.
Also be sure you are rolling and tucking the loaf snuggly. Since this has already been proofed twice and going right into the oven, it’s a little less forgiving but way easier.
Can I use shredded cheese instead of cheese powder?
I do not recommend it for this swirl method. I tested shredded cheddar twice, and both times it melted and left large tunnels in the crumb, even when I used little and tossed it in cornstarch. Cheese powder is what makes this loaf hold together. But if you want to try adding some, I would keep it around 1/4- 1/3 cup.
Can I make this without everything bagel seasoning?
Yes. You can swap the everything bagel seasoning for dehydrated onion or dehydrated garlic, or leave it out entirely for a straightforward cheddar swirl.
Can I add the filling after the dough has proofed?
Yes, that is what we are doing here. Because the loaf is cold and firm from its final proof in the fridge, it holds up to being cut, filled, and rolled without losing much of its structure. You add the filling right before baking and skip a second proof.
Do I need a special pan for the double pan method?
No. Any two loaf pans of the same size work, with one inverted over the other to act as a lid. I use a 10 by 5 inch USA pan. If you use different sizes, expect to have a possible change in baking time.
How do I know when the loaf is done?
Bake until the internal temperature reaches 190 degrees Fahrenheit. The cheese powder gives the crust a golden color, so use a thermometer rather than relying on color alone to know the crumb is fully baked.
