How To Bake Meatball Casserole

Step 1: Prepare the Oven and Baking Dish

Get your oven ready by heating it to 375°F. Grab a 9×13-inch baking dish and coat it generously with cooking spray or butter to prevent any sticky situations.

Step 2: Create the Magical Mixture

• Uncooked penne pasta
• Marinara sauce
• Frozen meatballs
• Dried oregano
• Dried basil
• Garlic powder
• Black pepper
• Salt

Gently stir everything together until the pasta and meatballs are completely coated with sauce and seasonings.

Step 3: Spread the Goodness

Transfer the entire mixture to your prepared baking dish, spreading it out evenly to ensure every bite is packed with flavor.

Step 4: Cover and Bake

Wrap the dish tightly with aluminum foil to lock in moisture and help the pasta cook perfectly. Pop it into the preheated oven and bake for 35 minutes.

Step 5: Add the Cheesy Topping

• Shredded mozzarella cheese
• Grated parmesan cheese

Return the dish to the oven uncovered and bake for an additional 10-15 minutes until the cheese is melted, bubbly, and develops golden edges.

Step 6: Rest and Serve

Pull the casserole out of the oven and let it rest for 5 minutes. This allows the sauce to set and the flavors to mingle. Serve directly from the baking dish, making sure each serving has plenty of meatballs, pasta, and that irresistible cheesy goodness.
