Classic Creamy Bacon Cheese Pasta Bake (Print version)

A creamy bacon cheese pasta bake with tender pasta, crisp bacon, cheddar sauce, and a golden baked top.

# Ingredients:

For the pasta and bacon

01 - 12 oz (340 g) penne, cavatappi, or rigatoni
02 - 10 oz (285 g) bacon, chopped
03 - Salt for the pasta water

For the cheese sauce

04 - 2 tablespoons unsalted butter
05 - 1 small yellow onion, finely diced
06 - 3 cloves garlic, minced
07 - 3 tablespoons all-purpose flour
08 - 2 cups (480 ml) whole milk
09 - 1/2 cup (120 ml) heavy cream
10 - 1/2 teaspoon mustard powder
11 - 1/2 teaspoon kosher salt, plus more to taste
12 - 1/4 teaspoon black pepper
13 - 2 cups (225 g) shredded sharp cheddar cheese
14 - 1/3 cup (30 g) grated Parmesan cheese

For the topping

15 - 1 cup (110 g) shredded mozzarella cheese
16 - 2 tablespoons chopped parsley, optional

# Instructions:

01 - Preheat the oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish if your skillet is not oven-safe.
02 - Boil the pasta in salted water for 1-2 minutes less than the package directions. Reserve 1 cup of pasta water, then drain.
03 - Cook the chopped bacon in a large skillet over medium heat until crisp, 8-10 minutes. Transfer to a paper towel-lined plate and leave about 1 tablespoon of drippings in the skillet.
04 - Add the butter and onion to the skillet. Cook for 3-4 minutes until softened, then add the garlic for 30 seconds. Stir in the flour and cook for 1 minute.
05 - Whisk in the milk a little at a time, then whisk in the cream. Simmer for 4-5 minutes until lightly thickened. Reduce the heat to low and stir in mustard powder, salt, pepper, cheddar, and Parmesan until smooth.
06 - Fold in the drained pasta and most of the bacon. Add 1/4 to 1/2 cup reserved pasta water as needed so the sauce looks loose and glossy.
07 - Transfer to the baking dish if needed. Sprinkle with mozzarella and the remaining bacon. Bake for 18-22 minutes until bubbling at the edges and golden on top.
08 - Let the pasta bake rest for 8-10 minutes before serving. Sprinkle with parsley if using.

# Good to know:

01 - Best served after a short rest so the sauce settles.
02 - Undercook the pasta slightly because it continues cooking in the oven.
03 - Add reserved pasta water before baking if the sauce looks thick.
