Description

This Dump and Bake Meatball Casserole is cheesy, saucy, and ready in no time — the easiest comfort food your whole family will love!

Ingredients

12 oz uncooked rotini or penne pasta

1 (24 oz) jar marinara sauce

3 cups water

1 (1 lb) bag frozen fully cooked meatballs

1 teaspoon Italian seasoning

1/2 teaspoon garlic powder

1/2 teaspoon onion powder

2 cups shredded mozzarella cheese

1/4 cup grated Parmesan cheese

Optional: Fresh basil or parsley for garnish

Instructions

Step 1: Preheat & Prep

Preheat your oven to 425°F (220°C). Lightly grease a large 9×13-inch baking dish.

Step 2: Dump the Ingredients

In the baking dish, combine uncooked pasta, marinara sauce, water, Italian seasoning, garlic powder, and onion powder. Stir to evenly distribute the pasta.

Step 3: Add Meatballs

Arrange frozen meatballs evenly over the top of the pasta mixture. No need to thaw — they’ll cook as the casserole bakes.

Step 4: Bake

Cover the dish tightly with foil and bake for 35 minutes.

Step 5: Add the Cheese

Remove the foil, stir everything gently, and top with mozzarella and Parmesan cheese. Return to the oven, uncovered, for 10–12 minutes, or until the cheese is melted, bubbly, and slightly golden.

Step 6: Serve

Let the casserole cool for 5 minutes, garnish with fresh herbs, and serve hot.

Notes

Use fully cooked frozen meatballs — any variety works: beef, turkey, chicken, or plant-based.
Don’t skip the foil — it traps steam and helps the pasta cook evenly.
Add a little spice — sprinkle in crushed red pepper flakes for a kick.
