Think of this jalapeño cheddar sourdough bread as a jalapeño popper that grew up and got serious about crust. Sharp cheddar and dry-sautéed jalapeño fold into the dough together in one simple step. Then the top gets one more layer of melty cheese and jalapeño before it finishes baking. It’s spicy, cheesy, and honestly kind of dangerous toasted with butter.

My Favorite Jalapeño Cheddar Sourdough Bread
This jalapeño cheddar sourdough bread is what happens when I decide savory sourdough doesn’t need to be complicated. Sharp cheddar and dry-sautéed jalapeño get folded straight into my classic sourdough base. Then the top gets one more layer of melty cheese and pepper before it finishes baking. It’s spicy, cheesy, and honestly kind of dangerous toasted with butter.
I tested a LOT of different ways to make this bread and I fully believe this is the easiest, most reliable way to make a good Jalapeno Cheddar Sourdough loaf.
One of the trickiest things about this recipe is the moisture from the jalapenos and the cheese. Get it right and the loaf is magic. Make it too wet and you get a gummy middle… This recipe will set you up for success with winning flavor and crumb!
Why You’ll Love This Jalapeño Cheddar Sourdough Bread
- Incredible toasted. Hot slices, melty cheese pockets throughout the crumb, a little heat from the jalapeño — this is my husband’s favorite way to eat it and I’m not going to argue with him. (I mean why would you argue with somebody who is right?)
- A familiar, forgiving technique. If you’ve already made my chocolate chip or blueberry sourdough, you already know exactly how to fold something into this dough. This is the same method, just headed savory this time.
- Real cheddar flavor in every bite, not just on top. Folding cheddar into the dough itself means pockets of cheese all the way through the loaf. The crust is just a bonus!
- Built-in flexibility. Prefer canned jalapeño over fresh? Want a milder version? I’ve got notes for both.
What You Need to Know Before You Start
Dry sautéing your jalapeños. Heat a skillet over medium-high with no oil, add your diced jalapeño, and keep it moving constantly for a couple of minutes until it looks slightly dried and blistered rather than wet and glossy — you’re sweating off moisture, not browning anything. Let it cool completely before it goes near your dough. I dramatically prefer fresh jalapeño here, but if you’re using canned: drain to 75g and pat dry first. Same goal either way — no extra moisture, no gummy crumb. (I use this chopper for easy cutting and keeping the chunks even for good distribution in the bread.)
Freshly grating the cheese matters. Grabbing any shredded cheese in advance is likely to cause issues. Grating your own ensures that there are no fillers or anything added that will cause melting issues. This box grater has a special box at the bottom perfect for catching the cheese!
A touch of honey and a little extra salt. This dough gets 10g of honey along with 13g of salt (instead of the 10g in my basic loaf). Both are small tweaks, but they round out the sharpness of the cheddar and keep a bold, spicy loaf tasting balanced instead of one-note.
Your starter should be active and bubbly when you begin. If it’s sluggish, the dough will be too. (Full starter guide here if you have questions.)
How to Make Jalapeño Cheddar Sourdough Bread
Mix your water, honey, starter, flour, and salt into a rough, shaggy dough — that raggedy texture is exactly right. Cover and let it rest for an hour so the flour hydrates and gluten starts building on its own.
Over the next two hours, work through four sets of stretch and folds. The jalapeño and cheddar only go in during the very first set, a quarter of each with every fold, so both distribute evenly instead of clumping in one spot.
Let the dough bulk ferment at room temperature for several hours, watching for the same cues as any of my loaves: doubled in size, pillowy like a marshmallow, jiggly when nudged, full of bubbles along the sides of the bowl.
Shape into a tight boule with a very light hand on the water mister, then tuck it seam-side up into a rice-floured banneton for an overnight cold retard. That slow chill builds flavor and makes scoring so much easier straight from the fridge.
Preheat your Dutch oven a full hour before baking. Score the cold dough, bake covered first, then uncover partway through to add the reserved cheese and jalapeño topping before finishing uncovered until deep golden and bubbling.
Let it cool completely before slicing in. Cutting too soon steals the texture you just spent a whole day building.
No Dutch oven? My graniteware roasting pan method works beautifully too — it’s not a straight preheat swap, so head to that post for the exact process.
Mirlandra’s Tips for Success
- Add all the jalapeño and cheddar during your first stretch and fold set, not spread across all four sets — one and done, evenly distributed.
- Fresh jalapeño, dry-sautéed, is my strong preference for flavor and texture. Canned works in a pinch — just drain to 75g and pat dry.
- Want it milder? Remove the seeds and ribs from your jalapeños before dicing — that’s where most of the heat lives.

My Favorite Jalapeño Cheddar Sourdough Bread
Ingredients
- 350 g lukewarm water
- 10 g honey
- 100 g active sourdough starter fed and happy
- 500 g bread flour
- 13 g fine grain sea salt
- 75 g fresh jalapeño whole pepper small dice (about 3-4 peppers), dry sautéed
- 75 g coarsely shredded sharp cheddar cheese (can sub favorite kind of cheddar)
- 60 g white cheddar grated, for topping (optional)
- 5 thin slices of jalapenos about 3mm jalapeño slices, for topping (optional)
Instructions
Autolyze – Mix and Rest:
- In a large mixing bowl, add the water, honey, starter, flour, and salt. Mix with a dough whisk or wooden spoon until no dry bits remain — you’re looking for a rough, shaggy dough, not a smooth one. That raggedy texture is exactly right at this stage. Cover and rest on the counter for 1 hour. This rest (called autolyze) lets the flour fully hydrate and gluten start forming on its own, so the dough gets easier to work with without you doing anything.
Stretch and Folds – Build the Structure (and Add the Jalapeño and Cheddar):
- This is where the jalapeño and cheddar go in. During your first set only, sprinkle in one quarter of your sautéed jalapeño and one quarter of your coarsely grated cheddar together with each of the four folds, so both distribute evenly instead of clumping in one spot. (For best results please grate your own cheese on the large setting of a normal grater.)
- Get your hands wet so the dough doesn’t stick to you. Grab one side of the dough, pull gently until it resists, then fold it back over itself. Rotate the bowl ¼ turn and repeat — four stretch and folds makes one set. (Full stretch and fold video guide here.)
- Cover and rest 30 minutes, then do three more plain sets (nothing more to add) for a total of 4 sets over about 2 hours.
Bulk Ferment:
- Cover and let the dough rise at room temperature for 5–8 hours. You’re watching for the same signs as always: it should double in size, look smooth and pillowy like a marshmallow, show bubbles through the sides of the bowl, and jiggle a little when you nudge it. Warmer kitchens move faster, cooler ones take longer — that’s normal, so let the dough tell you when it’s ready rather than the clock.
Shape:
- Turn the dough onto a counter misted very lightly with water and shape into a tight boule, building surface tension without deflating those hard-earned air bubbles. Place seam-side up in a rice-floured banneton.
Cold Retard:
- Cover and refrigerate overnight, 8–12 hours. This slow, cold rise is what gives you deeper flavor and a dough that’s much easier to score straight from the fridge.
Bake:
- Preheat your Dutch oven at 450°F for a full hour — don’t rush this part, a properly hot pot is what gives you that oven spring and crackly crust. Turn the cold dough out onto parchment, score it, mist very lightly with water, and lower it into the pot.
- 450°F, 30 minutes, lid on
- At the 30-minute mark, carefully remove the lid and top the loaf with your reserved 60g white cheddar and 5 thin jalapeño slices.
- 410°F, 15 minutes, lid off, until deep golden and the cheese on top is melted and starting to bubble and brown.
- No Dutch oven? My graniteware roasting pan method works beautifully too — it’s not a straight preheat swap, so head to that post for the exact process.
Cool:
- Cool completely on a wire rack before slicing — 3–4 hours. I know the smell is unfair. Cutting in early releases steam and leaves you with a gummy crumb, so let it be.
