Ingredients

Main Ingredients

1 pound frozen meatballs
1 can (24 ounces) pasta sauce
1 cup water
2 cups uncooked pasta (such as penne or rigatoni)
1 cup shredded mozzarella cheese
1/4 cup grated Parmesan cheese

Optional Garnish

Fresh basil or parsley

Method

Step 1: Preheat Oven and Prepare Dish

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish to prevent sticking and allow easy cleanup.

Step 2: Combine Ingredients

Place the frozen meatballs in the prepared baking dish. Pour the pasta sauce and 1 cup of water over the meatballs. Add the uncooked pasta and stir gently to ensure the pasta is mostly submerged in the sauce. Season with salt and pepper if desired.

Step 3: Bake Covered

Cover the baking dish with aluminum foil and bake for 35 minutes. Stir gently halfway through to ensure even cooking of the pasta and meatballs.

Step 4: Add Cheese and Finish Baking

Remove the foil and sprinkle the shredded mozzarella and grated Parmesan cheese evenly over the casserole. Return to the oven, uncovered, and bake for an additional 10–15 minutes, or until the cheese is melted, bubbly, and lightly golden.

Step 5: Serve

Remove from the oven and allow the casserole to rest for 5 minutes. Garnish with fresh basil or parsley if desired. Serve hot, ensuring each portion has a combination of meatballs, pasta, sauce, and melted cheese.

Tips for the Perfect Meatball Casserole

1️⃣ Frozen meatballs save time: No need to thaw — they cook perfectly in the sauce.
2️⃣ Submerge pasta: Make sure the pasta is mostly covered in sauce and water for even cooking.
3️⃣ Stir halfway: This prevents pasta from sticking together and ensures meatballs are evenly coated.
4️⃣ Cheese topping: Spread cheese evenly to get a uniform, golden crust.
5️⃣ Rest before serving: Letting it sit briefly allows the sauce to thicken slightly and makes serving easier.

Variations and Enhancements

• Vegetable Boost: Add diced bell peppers, spinach, zucchini, or mushrooms for extra nutrition and flavor.
• Spicy Kick: Mix in crushed red pepper flakes or use spicy Italian meatballs for a little heat.
• Cheesy Explosion: Add extra mozzarella or a mix of cheddar and provolone for a richer, gooier topping.
• Low-Sodium Option: Use low-sodium pasta sauce and adjust seasoning to taste.
• Gluten-Free: Use gluten-free pasta and check meatball ingredients to make it gluten-free.

Storage and Reheating

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350°F (175°C) for 10–15 minutes or in the microwave until warmed through. For longer storage, freeze in portions for up to 2 months; thaw overnight in the refrigerator before reheating.

Serving Suggestions

Serve this meatball casserole with a side of garlic bread, a crisp green salad, or steamed vegetables. It’s also great paired with a simple slaw or roasted vegetables for a complete, hearty meal. Leftovers make delicious sandwiches or can be spooned over additional pasta for an easy lunch.

Expert Advice for Maximum Flavor

The sauce and water mixture ensures pasta cooks thoroughly while absorbing all the flavors of the meatballs. Covering the casserole for most of the baking time locks in moisture, while uncovering at the end allows the cheese to brown beautifully. Adding fresh herbs just before serving provides a burst of color and aroma that elevates this simple dish.
