Old School Mac n' Cheese

1. Stage

Preheat oven to 375 degrees F (190 degrees C).

2. Stage

Bring a large pot of lightly salted water to a boil. Cook elbow macaroni in the boiling water, stirring occasionally until cooked through but firm to the bite, 8 minutes; drain.

3. Stage

Melt butter in a large pot over medium-low heat. Slowly add flour to butter, whisking constantly; cook until brown and the mixture no longer smells of flour, about 5 minutes. Pour 1 cup milk into the flour mixture, whisking continually until fully incorporated, about 45 seconds; repeat twice. Add remaining 3 cups milk to the mixture, whisking to incorporate. Stir Worcestershire sauce, mustard powder, onion powder, and cayenne pepper into the mixture; season with salt and black pepper.

4. Stage

Reduce heat to low. Cook sauce, whisking frequently, until it begins to thicken, about 10 minutes. Add about half the package of shredded Cheddar cheese; stir continually until the cheese melts completely. Repeat with remaining half package of Cheddar cheese and the American cheese, about 4 ounces at a time. Once cheese is entirely incorporated, remove sauce from heat.

5. Stage

Stir drained macaroni into the cheese sauce to coat. Divide macaroni between two 9x13-inch baking dishes.

6. Stage

Mix crushed potato chips, 1 cup shredded Cheddar cheese, and Parmesan cheese in a bowl. Top the macaroni with the potato chip mixture evenly. Spray the potato chip mixture with cooking spray.

7. Stage

Bake in preheated oven until the crust is golden brown and the sauce is bubbling, 35 to 45 minutes. RainbowJewels
