Take your sourdough game to the next level with this spectacular jalapeño-cheddar loaf. A classic crusty sourdough base, packed with sharp cheddar cheese and spicy pickled jalapeños, creating pockets of molten cheese and zesty heat throughout. It’s the perfect bread for sandwiches, toasted with butter, or just torn apart while still warm from the oven.
The tangy sourdough perfectly complements the rich cheese and spicy peppers—every slice is an adventure. This recipe builds on basic sourdough techniques with a few key additions for incorporating mix-ins without deflating the dough.
Instructions
Build the Levain (Evening Before)
The night before baking, combine the active starter, bread flour, and water in a small jar or bowl. Mix well, cover loosely, and let sit at room temperature overnight (8-12 hours). It should be bubbly, active, and smell pleasantly sour in the morning.
Mix the Dough
In a large bowl, combine the levain and warm water. Stir until the starter disperses. Add both flours and mix until a shaggy dough forms and no dry bits remain. Cover and let rest for 30-60 minutes (autolyse).
Add Salt
Sprinkle the salt over the dough. Wet your hands and incorporate the salt by pinching and folding the dough until fully absorbed. Cover and rest for 30 minutes.
Bulk Fermentation with Stretch and Folds
Over the next 2-3 hours, perform 4 sets of stretch and folds, every 30 minutes. During the second or third set, incorporate the cheese and jalapeños.
Gently stretch the dough out as much as possible without tearing, sprinkle about one-third of the cheese and jalapeños over the surface, then fold as usual. Repeat until all mix-ins are incorporated. The dough will become smoother and more elastic with each set.
Continue Bulk Fermentation
After the last set of folds, let the dough rest, covered, for another 1-2 hours. It should increase in volume by about 50%, look puffy, and have visible bubbles.
Shape the Dough
Lightly flour your work surface. Gently turn the dough out. With floured hands, gently shape it into a round or oval by folding the edges into the center, then flipping and dragging to create surface tension. Be careful not to deflate the dough too much.
Final Proof
Place the shaped dough seam-side up in a floured proofing basket (banneton). Cover and refrigerate overnight (8-12 hours) for best flavor, or let proof at room temperature for 1-2 hours until puffy.
Preheat the Dutch Oven
Place a Dutch oven with its lid in your oven and preheat to 475°F (245°C) for at least 45 minutes.
Score the Dough
Carefully remove the hot Dutch oven. Place a piece of parchment paper over the dough and invert the basket to release the dough onto the parchment. Using a sharp blade or lame, score the top with a simple slash or pattern—about ¼ inch deep.
Bake Covered
Using the parchment as handles, lower the dough into the hot Dutch oven. Put the lid on and bake for 25 minutes.
Bake Uncovered
Remove the lid and bake for another 20-25 minutes, until the crust is deep golden brown and the internal temperature reaches 205-210°F (96-99°C).
Cool Completely
Carefully remove the loaf from the pot and transfer to a wire rack. Cool completely—at least 2 hours. This is crucial for texture.
Slice and Enjoy
Once completely cool, slice with a serrated knife. Each slice reveals pockets of melted cheese and spicy jalapeños throughout. Toast and butter for the ultimate experience.
Pro-Tips for Jalapeño-Cheddar Sourdough
- Use Cold Cheese: Cold cheese cubes hold their shape during mixing and create beautiful melted pockets. Room temperature cheese can smear into the dough.
- Dry the Jalapeños: Pickled jalapeños contain moisture that can make the dough sticky. Drain well and pat thoroughly dry with paper towels.
- Add Mix-ins During Stretch and Folds: This distributes them evenly without deflating the dough.
- Be Gentle During Shaping: The cheese and peppers can tear the dough if you’re too aggressive. Handle with care.
- Score Deeply: A good score helps control where the bread expands.
- Cool Completely: The cheese inside will be molten hot and the crumb needs time to set. Be patient.
- Adjust Hydration: If your dough feels too wet after adding mix-ins, reduce water by 10-20g next time.
- Try Different Cheeses: Pepper Jack, smoked Gouda, or a mix of cheeses all work beautifully.
This Jalapeño-Cheddar Sourdough is spicy, cheesy, and absolutely irresistible.
