Jalapeño cheddar sourdough bread is made with an active sourdough starter, shredded cheddar, and fresh jalapeño. The dough develops its strength through a series of stretch and folds before an overnight cold proof and a Dutch oven bake.
The cheddar melts into pockets through the crumb and crisps at the edges where it touches the hot oven. The jalapeño brings a warm heat that builds as you eat. It is the loaf I make on soup night, and it never lasts long.
Why This Jalapeño Cheddar Sourdough Works
A digital scale is why this loaf turns out the same each time. A cup of flour changes with every scoop, but 500 grams is 500 grams. When your starter is this active and the salt is a single spoon, a few grams either way shifts the dough more than you would think. I weigh everything in grams with my digital kitchen scale so the loaf comes out consistent every bake.
The secret to this loaf is not the ingredients, it is when they go in. Cheddar and jalapeño are sharp, and if you fold them in during the very first stretch, they tear the gluten before it has a chance to build. So the dough does one fold on its own first. Then the cheese and peppers go in on the second fold, when the dough is strong enough to hold them without ripping. That one small bit of patience is what gives you even pockets of melty cheese instead of a dense, ragged loaf.
The second thing that makes it work is the timing. This bread does not rush. It gets three gentle folds, a slow rise, and then a full night in the fridge. That cold proof is where the flavor is, and it does more than deepen the tang. Cold dough scores neatly and holds its shape when it hits the hot Dutch oven, so you get a taller loaf with a better ear and a more open crumb.
And bake it by temperature, not by eye. The crust can look perfectly done while the middle is still doughy. A thermometer is the only way to be sure. Mine comes out of the oven at 209°F, and the difference between that and a fully browned on the outside, gummy on the inside loaf is the single cheapest tool in your kitchen.
How to Make Jalapeño Cheddar Sourdough
- Feed the starter. Several hours before mixing, feed your starter so you have at least 100 grams of active starter for the recipe plus a little left over to maintain it. Combine 25 grams starter, 50 grams water, and 50 grams bread flour. Stir, mark the level on the jar, and leave it at room temperature.
- Let it rise until it has at least doubled and is bubbly and puffy. This takes about 4 to 8 hours depending on your kitchen. Measure out 100 grams for the dough and keep the rest for your next feed.
- Mix the dough. Add 350 grams of water and 100 grams of active starter to a large bowl and stir to combine. Add 500 grams of bread flour and 10 grams of salt and mix until no dry flour remains and a shaggy dough forms. Cover and rest 1 hour.
- Stretch and folds. With a damp hand, grab one side of the dough and stretch it up until you feel it resist. Fold it over the center, turn the bowl a quarter turn, and repeat around all four sides. Cover and rest 30 minutes.
- Add the cheddar and jalapeño. Sprinkle 100 grams of shredded cheddar and 30 grams of diced jalapeño over the dough. Fold the dough over the cheese and peppers as you work around the bowl so they distribute evenly. Cover and rest 30 minutes.
- Final fold and bulk ferment. Do one more set of stretch and folds, stopping at resistance. The dough should feel smoother and stretchier now. Cover and let it rise 2 more hours. It is ready to shape when it has puffed up, jiggles slightly, has scattered bubbles on the sides and top, and has pulled away from the edges of the bowl.
- Shape. Turn the dough onto a lightly floured surface and shape it into a round, building tension across the outside without pressing out all the air.
- Transfer to the banneton. Place the dough seam-side up in a well-floured banneton. Stitch the seam gently to tighten. Cover and rest at room temperature for 30 minutes.
- Cold proof. Refrigerate overnight, then bake straight from the fridge the next day.
- Preheat. Place the Dutch oven and lid in the oven and preheat to 450°F for 30 minutes.
- Score. Turn the dough onto parchment, smooth side up. Score the top with a lame or sharp blade so it can expand in the oven.
- Bake. Lower the dough into the hot Dutch oven by the parchment. Replace the lid and bake 30 minutes. Remove the lid and bake 20 to 25 more minutes until deeply golden and it reads 205 to 210°F inside.
- Cool. Move the loaf to a wire rack and cool at least 2 hours before slicing so the crumb can set.
How Long to Bake Jalapeño Cheddar Sourdough
Covered for 30 minutes sets the rise and builds the crust. Uncovered for 20 to 25 more minutes finishes the color. The loaf is done when the center reads 205 to 210°F.
If the crust browns before the center finishes, drop the temperature slightly and leave it uncovered. Color is not the same as doneness so use a thermometer.
How to Store and Reheat
Store the loaf cut-side down on a cutting board for the first day to keep the crust crisp. After that, wrap it in a kitchen towel or a paper bag. Plastic softens the crust, so reserve it for when you have cut the loaf and want to keep the inside moist.
Reheat a slice in the toaster or a hot oven for a few minutes to bring the crust back. A full loaf refreshes at 350°F for 10 minutes.
Freeze a whole loaf wrapped in plastic, then foil. It keeps two months. Thaw at room temperature and refresh in the oven.

📖 Recipe
Jalapeño Cheddar Sourdough
Ingredients
- 100 grams active sourdough starter
- 350 grams water
- 500 grams bread flour
- 10 grams salt
- 100 grams shredded cheddar cheese
- 30 grams fresh jalapeño - diced
Instructions
Feed the Sourdough Starter
- Several hours before making the dough, feed your starter so you have at least 100 grams of active starter for the recipe plus a little left over to maintain it. For example, combine 25 grams starter, 50 grams water, and 50 grams bread flour. Stir, mark the level on the jar, and leave it at room temperature.
- Let the starter rise until it has at least doubled and is bubbly and puffy, about 4 to 8 hours depending on your kitchen. Measure out 100 grams of active starter for the dough. Keep the rest to feed for your next bake.
Make the Dough
- Mix the dough. Add 350 grams water and 100 grams active starter to a large bowl and stir to combine. Add 500 grams bread flour and 10 grams salt and mix until no dry flour remains and a shaggy dough forms. Cover and rest for 1 hour.
Stretch and Folds
- First stretch and fold. With a damp hand, grab one side of the dough and stretch it up until you feel it resist. Fold it over the center, turn the bowl a quarter turn, and repeat around all four sides. Cover and rest 30 minutes.
- Second stretch and fold. Add the cheddar and jalapeño. Sprinkle 100 grams shredded cheddar and 30 grams diced jalapeño over the dough.
- Third stretch and fold. Do another set of stretch and folds, folding the dough over the cheese and peppers as you work around the bowl. Cover and rest 30 minutes.
- Final stretch and fold. Do one more set, stopping at resistance. The dough should feel smoother and stretchier now.
Rest
- Cover the dough and let rise for 2 more hours. You'll know the dough is ready to shape when the dough is puffed up, slightly jiggles, has scattered bubbles visible on the sides and top and it is pulled away from the edges..
Shape
- Turn the dough onto a lightly floured surface and shape it into a round, building tension to create a round shape.
- Transfer to a floured banneton. Place the dough seam-side up in a well-floured banneton. Stitch the seam gently to tighten. Cover and rest at room temperature for 30 minutes.
Cold Fermentation
- Cold proof by refrigerating overnight. Bake straight from the fridge the next day.
Bake
- Place the Dutch oven and lid in the oven and preheat to 450°F for 30 minutes.
- Turn the dough onto parchment, smooth side up. Score the top with a lame or sharp blade. This is important for expansion.
- Lower the sourdough boule into the Dutch oven by the parchment paper. Replace lid and bake for 30 minutes.
- Remove the lid and bake 20 to 25 more minutes until deeply golden and it reads 205 to 210°F inside.
- Cool on a wire rack at least 2 hours before slicing.
Notes
- A ready starter has doubled in size and is bubbly and puffy.
- Use fresh jalapeño. Pickled jalapeño changes the flavor.
- Shred your own cheddar. Pre-shredded does not melt into pockets as well.
- Stop stretching at resistance so you do not tear the dough.
- Bake to 205 to 210°F inside, not just by color.
- Cool at least 2 hours so the crumb can set.
