How to Make Jalapeño Cheddar Sourdough Bread (or with Other Hot Peppers)

A few months ago I got myself going with a sourdough starter. A sourdough starter is basically fermented flour, and once you create this starter, you have to constantly feed it to keep it alive. And since so much work goes into keeping it alive, I’m always looking to try new recipes that use the sourdough starter. A lot of those recipes will end up on here, including sourdough bread, English muffin bread, and sourdough chocolate chip cookies.

(If you don’t have a sourdough starter yet, I’ll post directions in an upcoming post. Once I do that, I’ll link to it here.)

In addition to having this sourdough starter to utilize, I also have several jars of pickled hot peppers from last year’s garden that need to be eaten before the fall harvest and a fresh batch of peppers—so that got me thinking about a cheddar and hot pepper sourdough bread!

What I’ve done here is a bit of a mishmash of two recipes—my existing sourdough recipe and a cheddar jalapeño sourdough recipe I found online. I didn’t really like the steps of the new recipe, so I adapted my existing recipe to make a tasty hybrid.

Sourdough is remarkably simple in terms of ingredients. It’s literally sourdough starter (which is flour and water), more water, more flour, and salt.

With the sourdough recipe I use, I start the dough the night before and then let it rest and rise overnight at room temperature. You can leave it on the counter, but I have a cat that loves anything made with flour, so I have to stick it in the microwave or oven so it stays safe from him.

Theoretically, when the dough rests overnight, it should double in size. However, this is highly dependent on ideal local climate conditions and Winnipeg in the middle of winter is not an ideal climate. I’ve been told that Winnipeg in the summer isn’t ideal either. While I get some rise in my dough, it’s nowhere near double. So don’t panic if you don’t get the kind of rise you see on other blogs.

After resting overnight, it’s time to work in the peppers and cheese.

While this recipe is for jalapeño and cheddar sourdough, what I have on hand are pickled banana peppers. I like the taste of banana peppers better, but they’re also a lower on the Scoville scale, meaning they’re not as hot as jalapeño peppers—so if you like the sound of this recipe but you’re not sure if you can handle jalapeños, banana peppers might be the way to go.

(You can usually find pickled banana peppers in the condiments aisle of your grocery store, next to things like ketchup and mustard. If the jars are labelled with “mild” or “hot”, you’ll want to go with the hot ones. The mild ones can have the same heat level as bell peppers, which would be kind of pointless for this recipe.)

With the “pinch and fold” method, we start working the cheese and peppers into the dough. (Full directions on how to do this are in the recipe below.)

The original jalapeño cheddar sourdough recipe I looked up had the cheese and peppers mixed in with the dough at the very beginning. The end result would give cheese and peppers spotted throughout the loaf, whereas my method here results in a ribbon of cheese and peppers that runs through the whole loaf.

While I like the idea of cheese and peppers being spread throughout like little morsels of goodness, I didn’t like the idea of leaving the cheese (a dairy product) at room temperature overnight while the dough was resting. To be fair, that recipe had the dough in the fridge overnight, but if I’m having enough difficulty getting a rise out of my dough at room temperature, I’d have much poorer results in the fridge.

After resting for a bit we do another round of “pinch and folds” to work the cheese and peppers in a bit more. However, be a bit gentler at this stage. I found I’d ripped the dough in one spot and cheese started tumbling out; I hadn’t realized the cheese had migrated so close to the surface of the dough ball.

Now we let it rest one final time in a bowl lined with a towel and sprinkled with flour.

Toward the end of the 30-60 minute rest, we crank the oven up to 450 F.

Transfer the dough to some parchment paper—pinch seam side down—and cut some slits in it, then transfer the whole thing to a dutch oven.

Lower the heat to 425 F, then put the dutch oven (with the lid on) on the centre rack. Bake for 20 minutes, then remove the lid and bake for an additional 40 minutes. If it looks like it needs a little longer, you could give it an additional ten minutes. (When I pulled it out and later sliced into it, it looked like it could have used just a little bit longer. The addition of the cheese likely altered the baking time just a little bit.)

Transfer to a wire rack and let it cool for at least an hour before slicing into it.

This was my first time making a cheddar and hot pepper bread and I would absolutely make it again!

Sourdough is usually chewy, but this was chewy and extra soft. The tang of the hot peppers had worked its way into the rest of the bread, so even when I wasn’t biting into a pepper, I could taste them. The cheddar cooked perfectly—not so cooked that it’s crunchy, but cooked enough that it’s solid.

This tastes wonderful at room temperature with some butter, but would likely taste amazing toasted, buttered, and served alongside a spicy pasta dish.
