Instructions
 

Casserole

  • Preheat the oven to 350°F and grease a 9×13-inch baking dish.
  • Cook 8 ounces rotini according to package directions until al dente, about 8 minutes, then drain.
  • In the pasta pot, stir in 1 pound thawed meatballs, 3 cups marinara sauce, and 2 teaspoons Italian seasoning until evenly coated.
  • Transfer the mixture to the prepared dish and sprinkle 1 cup of mozzarella cheese over the top.

Cheese Topping

  • Cover with foil and bake for 20 minutes.
  • Remove foil, add the remaining 1 cup mozzarella and ½ cup Parmesan, then bake uncovered for 5 minutes until bubbling and golden at the edges.
  • Let the casserole rest for 5 minutes before slicing and serving.

Notes

Personal Testing Note: Thaw meatballs for 30 minutes before baking for the most tender bite.
Personal Testing Note: Layer half the mozzarella mid-bake to achieve both silky and crisp cheese textures.
Personal Testing Note: When reheating leftovers, add a splash of water to revive the sauce’s glossy consistency.
