Step-by-Step Instructions
Step 1 – Preheat and Prepare
Preheat your oven to 425°F (220°C) and lightly grease a 9×13-inch baking dish. This prep step ensures the casserole won’t stick and will bake evenly.
Visual cue: Make sure your dish is greased well.
Step 2 – Combine Ingredients
In the greased baking dish, stir together the uncooked penne pasta, marinara sauce, and water (or beef broth). This mixture forms the base of your casserole.
Step 3 – Add Meatballs
Add the frozen meatballs to the pasta mixture along with the Italian seasoning, garlic powder, and onion powder. Mix everything together until combined.
Step 4 – Cover and Bake
Cover the dish tightly with aluminum foil and bake for 35–40 minutes. You’ll know it’s ready when the pasta is tender.
Step 5 – Add Cheese
Remove the foil and sprinkle the mozzarella and Parmesan evenly over the top.
Step 6 – Bake Uncovered
Bake uncovered for an additional 10–15 minutes, until the cheese is melted, bubbly, and golden.
Step 7 – Rest and Garnish
Allow the casserole to rest for 5–10 minutes before serving and garnish with chopped parsley, if desired.

Pro Tips for Success
- Watch the Timing: Make sure to keep an eye on the baking time, as different ovens may have slight variations.
- Get the Right Texture: The pasta should be al dente before adding cheese, ensuring it doesn’t become mushy.
- Baking Dish: A glass or ceramic baking dish works best for even cooking.
- Seasoning: Adjust the Italian seasoning based on your taste preferences for a stronger flavor.
- Doneness Check: Test the meatballs for warmth if they are larger than standard size.
Flavor Variations
- Vegetarian Version: Substitute meatballs with your favorite plant-based variety.
- Spicy Kick: Add red pepper flakes to the sauce for a spicier casserole.
- Cheesy Delight: Incorporate different cheeses like gouda or fontina for a gourmet touch.
- Veggie Boost: Toss in a mix of chopped bell peppers or diced zucchini before baking for added nutrition.
- Creamy Twist: Stir in a dollop of cream cheese or ricotta to the pasta mixture for creaminess.
Serving Suggestions
- Pair with a light green salad dressed in vinaigrette for a refreshing contrast.
- Serve with garlic bread on the side for a complete Italian dining experience.
- Sliced black olives or pepperoncini can be added as garnishes for an extra zing.
- This dish is excellent for potlucks; simply bake and transport in the same dish!
Make-Ahead, Storage & Reheating
- Make-Ahead Options: You can prepare the casserole in advance and refrigerate it before baking. Just add an extra few minutes to the cooking time.
- Storage Duration: Store leftovers in the fridge for up to 3-4 days.
- Reheating: Reheat in the microwave or oven, covering with foil to prevent drying out. Expect minor texture changes after reheating, as pasta can soften.
Storage and Freezing Instructions
If you plan to freeze the casserole, it’s best to do so before adding the cheese topping. Once baked, the texture may become soggy upon reheating. If already baked, leftovers can still be frozen for up to 2 months, but the quality will vary. To reheat frozen leftovers, thaw in the fridge overnight and warm in the oven.
