# How-To Steps:

01 - Preheat oven to 375°F and grease a 9x13-inch baking dish with butter or cooking spray.
02 - Bring a large pot of salted water to a boil. Cook pasta until al dente according to package instructions, then drain and set aside.

06 - Add cooked pasta to the skillet and toss until all components are evenly coated.
07 - Pour the mixture into the prepared baking dish. Distribute mozzarella and Parmesan cheese evenly over the surface.
08 - Bake for 20 to 25 minutes until the mixture is bubbly and cheese reaches a golden brown color.
09 - Remove from oven and allow the bake to rest for 5 minutes before portioning and serving.

# Expert Tips:

01 -
  • The casserole format means you can assemble it earlier in the day, then just pop it in the oven when youre ready to eat without sacrificing flavor.
  • That moment when you pull back the first spoonful and the cheese stretches in long, perfect strands will make you feel like youve accomplished culinary magic.
02 -
  • If your sauce looks a bit thin before baking, resist adding thickeners as the pasta will absorb moisture during baking and the sauce will naturally concentrate.
  • Storing your shredded cheese in the freezer for 10 minutes before sprinkling on top prevents it from melting too quickly and gives you that picture-perfect golden crust.
03 -
  • When reheating leftovers, add a splash of milk or cream before microwaving to revive the creamy texture that can otherwise dry out.
  • For a beautiful presentation at dinner parties, I bake individual portions in ramekins, which creates more of those coveted crispy edge sections everyone fights over.
