Cook the pasta according to the package instructions.

While the pasta cooks, add the bacon to a saucepan and sauteé until crispy and cooked through. Remove from the pan and chop into bite-sized pieces.

Using the leftover bacon grease, sauteé the diced jalepeños for about 5 minutes until soft.

Return the chopped bacon to the pan and add 1 tablespoon butter.

Once the butter has melted, add 2 tbsps. of flour and whisk until combined.

When the pasta is done cooking, drain and add it to the pan.

Whisk in the heavy cream, shredded cheeses, and sour cream. Continue to whisk until cheese is melty and all the ingredients are combined.

Turn heat to low and allow to simmer and thicken, about 15 minutes. Continue to stir occasionally.

Add macaroni contents to an oven-safe baking dish and set your oven to broil.

Sprinkle the Italian bread crumbs on top of the macaroni and cheese.

Broil until crisp and golden, about 5 minutes. Keep an eye on it to make sure it doesn’t burn.
