Ingredients
- 1 pound frozen meatballs (beef, turkey, or chicken)
- 12 ounces penne pasta (uncooked)
- 3 cups marinara sauce
- 2 cups mozzarella cheese (shredded)
- 1 cup Italian blend cheese (shredded)
- 2 cups water
- 1 teaspoon garlic powder

- In a large baking dish, mix together the uncooked penne pasta, frozen meatballs, garlic powder, Italian seasoning, salt, and pepper.
- Pour the marinara sauce over the pasta and meatballs, then add the water. Stir gently to combine, ensuring that the pasta is submerged in the sauce.
- Cover the baking dish tightly with aluminum foil. This is crucial for the pasta to cook properly and absorb the flavors of the sauce.
- Place the dish in the preheated oven and bake for 30 minutes.
- After 30 minutes, carefully remove the foil and stir the casserole. It will likely appear saucy; this is what you want!
- Sprinkle the top with the mozzarella and Italian blend cheese.
- Return the dish to the oven, uncovered, and bake for an additional 15-20 minutes until the cheese is melted and bubbly.
- Remove from the oven and let it cool for about 5 minutes.
- Garnish with chopped fresh parsley if desired, and serve warm.

Storing Leftovers
