Sourdough Cheddar Jalapeño Loaf Recipe

A bold sandwich loaf with pockets of cheddar and jalapeño — heat level under your control.

Carlos Vega2 min read

Fold cubed cheddar and diced jalapeños into a moderate-hydration sourdough during bulk, shape tightly, and bake until the cheese caramelizes at the crust without burning the bottom.

Ingredients

  • 500g bread flour
  • 350g water (70%)
  • 100g ripe starter
  • 10g salt
  • 150g sharp cheddar, ½-inch cubes
  • 40–60g jalapeño, seeded and diced (fresh or pickled, drained)

Method highlights

Mix and strengthen as a standard country dough. Add cheese and peppers on the second fold so inclusions distribute without shredding gluten. Shape firmly — inclusions create weak points. Bake on a shield (sheet pan under Dutch oven) because cheese fat can encourage darker bottoms.

Baker's notes

Weights assume a digital scale. If your kitchen is warmer than ~75°F, expect faster fermentation and consider reducing starter percentage or using cooler water. If colder, extend bulk and rely on dough cues over the clock. Pat mix-ins dry; wet inclusions effectively raise hydration and can wreck strength.

Make-ahead and storage

Shaped dough can usually cold-proof overnight. Baked loaves keep best cut-side down on a board for a day, then bagged. For longer storage, freeze slices or whole loaves and reheat with a light sprinkle of water in a moderate oven.

One thing to remember

Cold dough scores cleaner; warm dough handles softer — use that on purpose.

Serving ideas

This bake shines the day after as much as fresh — plan sandwiches or toast so you are not forced to slice piping hot.

Flour notes

Bread flour gives structure; a little whole wheat boosts flavor and fermentation. If swapping to all-purpose, expect a softer, slightly lower loaf and don't chase the same open crumb.

Field notes

The fastest way to improve at this is to pair the technique with the same base dough for several weekends. Keep salt around 2%, know your dough temperature, and judge readiness with rise and feel before you invent exotic fixes. Whole-grain flour, warmer kitchens, and higher starter percentages all compress timelines — expect that interaction. Season the process to your kitchen, then play with inclusions once the base loaf is trustworthy.

Also useful: weigh everything, preheat longer than you think, and cool fully before you judge crumb quality. Those three habits make every other tip more reliable.

Frequently asked questions

Shredded cheese instead of cubes?

Cubes give pockets; shred melts into streaks — both tasty.

Pan loaf option?

Yes — great for grilled cheese slices.

Pepper jack?

Works; expect more melt and spice.

Inclusion loaves love consistent bulk timing — SourdoughAI keeps the ferment from racing while you prep mix-ins.
