Ingredients

Scale

Sauce and Meatballs

  • 1 (23-ounce) jar marinara sauce
  • 2 cups low-sodium chicken broth
  • 1 (16-ounce) bag fully cooked frozen meatballs, thawed (homemade or store-bought)

Pasta and Seasonings

  • 8 ounces pasta (penne, ziti, or rotini)
  • 1 teaspoon Italian seasoning
  • ½ teaspoon salt
  • ½ teaspoon black pepper

Cream and Cheese

  • 1 cup heavy cream (or half-and-half or milk)
  • 2 cups freshly shredded mozzarella cheese, divided

Instructions

  1. Preheat Oven: Preheat your oven to 400 degrees Fahrenheit and lightly spray a large 9×13-inch casserole dish with non-stick cooking spray to prevent sticking.
  2. Combine Ingredients: In the prepared casserole dish, stir together the marinara sauce, low-sodium chicken broth, thawed meatballs, pasta, heavy cream, Italian seasoning, salt, and black pepper until everything is well combined.
  3. Cover and Bake: Cover the casserole dish tightly with foil and bake it in the preheated oven for 20 minutes. This allows the pasta and meatballs to begin cooking and the flavors to meld.
  4. Uncover and Stir: Remove the foil carefully, stir the casserole to mix the ingredients evenly, then return it uncovered to the oven for another 20 minutes to cook the pasta through and allow the sauce to thicken.
  5. Add Cheese: Stir half of the shredded mozzarella cheese into the hot casserole until melted. Then, sprinkle the remaining mozzarella evenly on top.
  6. Bake Until Bubbling: Place the casserole back in the oven for an additional 5-10 minutes, or until the cheese on top is bubbly, melted, and slightly golden.
  7. Rest and Serve: Remove from the oven and let the casserole cool for 5 minutes before serving. Optionally, garnish with fresh basil and crushed red pepper flakes for added flavor.

Notes

  • You can substitute heavy cream with half-and-half or milk for a lighter dish.
  • If using homemade meatballs, ensure they are fully cooked before adding to the casserole.
  • Feel free to add vegetables such as spinach or bell peppers for extra nutrition and flavor.
  • Use gluten-free pasta to make this recipe gluten-free if needed.
  • Leftovers can be refrigerated for up to 3 days and reheated in the oven or microwave.
