Prep the jalapeños by slicing 1/2 of jalapeño into 4-5 1/8” ring slices and set aside. Take the remaining 1 1/2 jalapeños, and remove the stem, seeds, and white membrane.
Finely dice the peppers and set aside. You can leave the seeds for extra spice.
Prepare the cheddar by shredding it. Set aside.
Add instant yeast to hot water and let sit for 5 minutes.
Add 3 cups of aerated flour to a large mixing bowl with the salt.
Once the yeast is foamy, add the flour mixture and begin to work the mixture into a sticky but firm dough.
You can use your hands or a wooden spoon. While mixing, add the diced peppers and cheese and continue to work the dough.
Cover the bowl with a kitchen towel, damp cloth, or plastic wrap and let the dough rise for 1 hour in a warm place. It should double in size.
Preheat the oven to 450°F. Once warm, place the no knead jalapeno bread on a lightly floured surface and gently work the dough into a smooth round loaf. Try not to overwork the dough.
Add a large piece of parchment paper to the Dutch oven and place your dough inside.
Score the top of the dough by using a sharp knife with a fine edge or a razor blade. I like to score an “x” and 1/4” deep.
Lightly sprinkle the loaf with some cheese, and place the jalapeño slices flat around the top of the lid; press in slightly.
Cover with the lid, place in the hot oven, and cook at 450°F for 30 minutes.
Once complete, remove the lid and cook for 5-10 minutes until the crust is golden brown.
