Crusty Cheddar Jalapeno Sourdough Bread
A crusty sourdough loaf loaded with sharp cheddar and spicy jalapeños. It’s cheesy, with pops of heat in every slice, and it makes your kitchen smell incredible while it bakes.
This recipe shows you a straightforward way to mix cheddar and jalapeño right into your sourdough, giving you a loaf that toasts up beautifully and makes the best grilled cheese.
Why This Sourdough Works
The cheddar melts into little chewy pockets while the jalapeños soften and mellow, so you get a savory, spicy loaf that never tastes harsh. It’s the kind of bread that disappears fast, especially warm from the oven.
I keep coming back to this one because the flavor is bold without being complicated. The sourdough tang cuts through the richness of the cheese, and the crust stays shatteringly crisp.
Ingredients
- 500g (4 cups) bread flour: use a flour with at least 12% protein for a strong structure.
- 350g (1 1/2 cups) lukewarm water: about 85°F (29°C).
- 100g (1/2 cup) active sourdough starter: fed and bubbly, at 100% hydration.
- 10g (1 3/4 tsp) fine sea salt
- 170g (6 oz) sharp cheddar cheese: cubed into small pieces, about 1/4 inch.
- 2 medium jalapeños: finely diced; remove seeds for less heat, leave some in for extra kick.
- Olive oil: for the bowl and shaping.
- Rice flour or extra bread flour: for dusting the banneton.
Variations / Substitutions
- Pepper jack for the cheddar: you’ll get an even spicier loaf with the same melty texture.
- Milder jalapeños: use a green bell pepper or Anaheim chile for almost no heat while keeping the color.
- Add bacon: fold in 1/3 cup crumbled cooked bacon with the cheese for a smoky note.
- Dried chile flakes: swap the fresh jalapeños for 1 to 2 tablespoons of crushed red pepper flakes if that’s what you have.
Mexican Red Lentil Soup makes a comforting soup to pair with this bread.
How to Make Cheddar Jalapeno Sourdough Bread
Step 1: Mix the Dough
In a large bowl, combine the bread flour and lukewarm water and stir until no dry spots remain. Cover the bowl and let it rest for 30 minutes; this gives the flour time to hydrate fully and starts gluten development.
After the rest, add the active sourdough starter and the salt. Mix with your hand or a dough whisk until everything comes together into a shaggy, cohesive mass. It will feel sticky and wet, and that’s exactly right at this stage.
Step 2: Fold in the Cheese and Jalapeños
Scatter the cubed cheddar and diced jalapeños over the dough. Use a wet hand to gently fold and squish the additions through the dough, rotating the bowl as you go, until the pieces are evenly distributed. This should take about 1 minute.
You’ll see the cheese cubes holding their shape and the jalapeño flecks spread throughout. Don’t overwork the dough here; a gentle hand keeps the pockets of cheese intact.
Step 3: Stretch and Fold the Dough
Cover the bowl with a damp towel and let the dough rest for 30 minutes. Then, with a wet hand, grab one side of the dough, stretch it upward, and fold it over the center. Rotate the bowl a quarter turn and repeat until you’ve done 4 folds. This is your first set of stretches and folds.
Do three more sets of stretches and folds, each 30 minutes apart, for a total of 2 hours of bulk fermentation. By the end, the dough will be noticeably smoother, domed, and puffy, with a few warm air bubbles pressing against the surface. If your kitchen is cooler than 70°F (21°C), you may need an extra set or a longer rest between them.
Step 4: Shape the Loaf
Lightly flour a work surface and turn the dough out. Gently shape it into a round or oval without knocking out too much gas. Let it rest uncovered for 20 minutes. This bench rest relaxes the gluten and makes the final shaping easier.
After the bench rest, reshape the dough into a tight boule or batard, whichever fits your banneton. Place it seam side up in a floured banneton or a bowl lined with a floured kitchen towel. The dough should feel springy and full but not tight.
Step 5: Score and Bake
Place a Dutch oven with its lid inside your oven and preheat to 475°F (245°C) for at least 40 minutes. While the oven heats, let the loaf proof at room temperature, about 60 to 90 minutes, until it looks puffed and a gentle poke leaves a slow indentation.
Once the oven and pot are fully heated, turn the loaf out onto a piece of parchment paper. Use a sharp lame or razor blade to score the top, a single slash or a cross, to direct the rise. Carefully lower the dough into the hot Dutch oven, cover with the lid, and bake for 30 minutes. Remove the lid and bake another 15 to 20 minutes until the crust is deeply golden.
Step 6: Turn Out and Slice
Lift the loaf out by the parchment and set it on a cooling rack. Let it cool for at least 1 hour so the crumb sets; cutting too early makes it gummy. Then slice with a serrated knife and enjoy warm, crusty slices with the cheese still a little soft inside.
Tips for the Best Cheddar Jalapeno Sourdough
- Use a truly active starter: feed it 4 to 6 hours before mixing so it floats in water and makes the dough rise reliably.
- Don’t overseed the jalapeños: scraping the inner white membrane tames the heat while still giving you pepper flavor.
- Keep the cheese cubed, not shredded: cubes create gooey pockets; shredded cheese melts into the dough and can make the crumb greasy.
- Watch the dough, not the clock: use the poke test—if the dough doesn’t spring back, it’s ready to bake; if it springs back fast, give it more time.
- Cool completely before storing: even a little residual warmth creates condensation and softens the crust.
Approximate bulk fermentation time by room temperature:
| Temperature | Bulk fermentation time |
|---|---|
| 65°F (18°C) | 5 to 6 hours |
| 70°F (21°C) | 4 to 5 hours |
| 75°F (24°C) | 3 to 4 hours |
| 80°F (27°C) | 2.5 to 3 hours |
Storing and Reheating
- Refrigerate: the loaf in a paper bag inside a plastic bag for up to 5 days. The crust stays crisper than if you use plastic alone.
- Reheat: slices in a 350°F (175°C) oven for 5 to 8 minutes to revive the crust.
- Serve cold: sliced thin with butter and flaky salt, it’s just as good for a snack.
What to Serve With Cheddar Jalapeno Sourdough
A thick slice of this bread makes a killer grilled cheese with extra cheddar and a smear of spicy mustard. It’s also great alongside a bowl of black bean soup or chili, where the heat in the bread echoes the warm spices. For breakfast, toast a slice and top it with a fried egg so the yolk runs into all those cheesy pockets.
Frequently Asked Questions
Can I use a different cheese?
Yes. A sharp provolone or Monterey Jack works well, anything that melts into soft streaks without releasing too much oil.
How do I make it spicier?
Leave in the jalapeño seeds and membrane, or replace one of the jalapeños with a serrano pepper. You can also add a teaspoon of chipotle flakes.
Can I use sourdough discard instead of active starter?
You can, but the rise will be slow and the loaf denser. It’s better to feed the discard for a few hours until it’s bubbly before using it here.
Why did my loaf come out flat?
It usually means the dough overproofed or the starter wasn’t strong enough. Next time, do the poke test earlier and make sure your starter passes the float test before mixing.
