Ingredients & Variations

The basics for this recipe are pasta, marinara, cream and loads of cheese!

MARINARA Store-bought or homemade will both taste amazing. Pasta sauce can be used too, whatever you have on hand!

SEASONINGS Garlic, Italian seasoning, and fresh basil are all added to this dish. Feel free to add any other spices you’d like!

For a basil garnish on the top, lay basil leaves one on top of the other and roll them up from one end to the other. Slice thinly from one end to the other until the basil looks like ribbons. This is called chiffonade and is a very popular way to garnish with basil! Try it!

Tips for Success

  • If using ground meat in a pasta cheese bake, pre-cook and drain it before adding to the casserole dish.
  • Use finely shredded mozzarella cheese so it melts quickly and evenly.
  • To brown the cheese, broil for 2-3 minutes or until bubbly.

  • cup heavy cream
  • 24 ounces marinara sauce or pasta sauce
  • 14.5 ounces petite diced tomatoes drained
  • 2 cups mozzarella cheese shredded
  • 2 tablespoons fresh basil or parsley


  • Preheat the oven to 350°F.
  • Cook pasta in salted water al dente according to the package directions and drain.

Cook pasta to al dente (firm) as it will cook a bit more in the oven.

Cooked meat such as rotisserie chicken, ham or ground sausage can be added. Add any cheese you have on hand on top of this dish.
Do not overbake or the dish can become dry.
