Ingredients
Prep Time: 10 minutes
Cook Time: 45–55 minutes
Total Time: 55 minutes
Servings: 6 servings
- 1 (12 oz) box uncooked penne pasta
- 1 (24 oz) jar marinara sauce
- 3 cups water (or beef broth for more flavor)
- 1 (1 lb) bag frozen meatballs (about 24 meatballs)
- 1 teaspoon Italian seasoning
- 1/2 teaspoon garlic powder (optional)
- 1/2 teaspoon onion powder (optional)
- 1 ½ cups shredded mozzarella cheese
- 1/4 cup grated Parmesan cheese
- Fresh parsley, for garnish (optional)

The main ingredients in this casserole are simple yet flavorful. The penne pasta offers a delightful texture, while the marinara sauce provides a rich and tangy base. Frozen meatballs save time, and you can choose beef, turkey, or even vegetarian options. Adding Italian seasoning, garlic powder, and onion powder elevates the flavors, making each bite more delicious. The mozzarella and Parmesan cheese give it that gooey, cheesy finish we all love!
Step-by-Step Instructions
Step 1: Preheat your oven to 425°F (220°C). While the oven heats up, lightly grease a 9×13-inch baking dish to ensure easy removal of the casserole later.
Step 2: Combine Ingredients. In the greased baking dish, stir together the uncooked penne pasta, marinara sauce, water (or beef broth), frozen meatballs, Italian seasoning, and the optional garlic and onion powders. Make sure everything is well mixed and that the pasta is fully submerged in the liquid to ensure even cooking.
Step 3: Cover and Bake. Tightly cover the baking dish with aluminum foil. This step is crucial as it traps steam, helping the pasta to cook properly. Bake for 35–40 minutes or until the pasta is tender. Every oven is different, so check occasionally.
Step 4: Add Cheese. Once the pasta has cooked, remove the foil and sprinkle the mozzarella and Parmesan cheese evenly over the top. The cheese not only adds flavor but also creates a beautiful golden, bubbly crust when it’s baked.
Step 5: Bake Uncovered. Return the casserole to the oven and bake uncovered for another 10–15 minutes or until the cheese is melted, bubbly, and golden brown. You can keep an eye on it to ensure it does not overcook.
Step 6: Let it Rest. After removing from the oven, allow the casserole to rest for 5–10 minutes. This resting period helps the dish to set and makes serving easier. If desired, garnish with freshly chopped parsley for added color and flavor.
Delicious Ways to Serve This Casserole
This meatball casserole is a complete meal on its own, but you can elevate your dinner experience with a few side dishes. Consider serving it alongside:
- A fresh green salad with a tangy vinaigrette
- Garlic bread for that quintessential Italian feel
- Steamed broccoli or green beans for a healthy vegetable option
- A glass of your favorite red wine or sparkling water
This dish also makes for a fantastic weeknight meal, family gatherings, game nights, or any casual get-together. Its comforting flavors appeal to both adults and children alike.
Storing and Reheating Tips
This casserole is great for meal prep! To store leftovers, let the casserole cool completely. Then, cover tightly with aluminum foil or transfer to an airtight container. The casserole can be stored in the refrigerator for up to 3–4 days.
If you want to extend its shelf life, you can freeze the casserole. To do this, tightly cover the unbaked prepared casserole with plastic wrap and aluminum foil. It can be frozen for up to 3 months. When you’re ready to eat, thaw it in the refrigerator overnight and then bake it as directed.
To reheat, simply place individual portions in the microwave, or reheat the entire casserole in the oven at 350°F (175°C) until warmed through. For a crispy topping, cover with foil initially, then remove it for the last few minutes of heating.
Expert Cooking Tips
Here are a few pro tips to ensure your casserole turns out perfectly:
- Don’t skip the browning step—baking the casserole uncovered at the end adds texture and flavor.
- If your pasta seems undercooked after the covered bake, don’t panic. It will continue cooking when topped with cheese and baked again.
- For an extra kick of flavor, add sautéed vegetables such as bell peppers, zucchini, or mushrooms to the mix before baking.
- Keep in mind that pasta shapes can affect cooking time; avoid using larger pastas that may need longer to cook.
Lastly, it’s essential to measure your liquid properly to ensure that the pasta does not dry out during cooking!
Possible Ingredient Swaps
One of the best aspects of this casserole is its versatility! Here are some variations you might consider:
- Use different types of pasta like rotini, fusilli, or even gluten-free pasta for those with dietary restrictions.
- Swap out the marinara for alfredo sauce, making a creamy meatball casserole.
- Try turkey or chicken meatballs for a lighter version—just ensure they’re fully cooked before adding them to the casserole.
- Add in your favorite vegetables such as spinach or kale for added nutrition.
Your imagination is the limit—tailor it to suit your tastes and dietary needs!
