Looking for the ultimate comfort food that brings the whole family to the table? This Meatball Casserole is a cheesy, saucy dream layered with tender meatballs, gooey mozzarella, and a savory tomato sauce that bubbles up into a crave-worthy meal. It hits all the notes of a hearty Italian dinner but comes together in one cozy casserole dish.

Whether you’re prepping ahead for a weeknight dinner or feeding a crowd, this dish is easy to love. With the convenience of store-bought or homemade meatballs and a few pantry staples, you get a dish that feels homemade with minimal fuss. Plus, it pairs beautifully with everything from garlic bread to a crisp Caesar salad.

What Kind of Meatballs Work Best for This Casserole?

You can use homemade meatballs if you’re going all out, or take a shortcut with your favorite frozen meatballs. The key is making sure they are fully cooked before layering them into the casserole. Beef, turkey, pork, or even plant-based options all work wonderfully, depending on your preference.

Ingredients for the Meatball Casserole

Meatballs – The star of the dish. Juicy, well-seasoned meatballs (homemade or frozen) provide the savory bite.

Marinara Sauce – A rich tomato sauce brings moisture and bold Italian flavor to every layer.

Mozzarella Cheese – Melts beautifully on top, creating a stretchy, golden topping.

Cheddar Cheese – Adds a sharp, creamy contrast that deepens the flavor profile.

Cooked Pasta – Optional, but makes the dish more filling. Rotini, penne, or shells are perfect.

Italian Seasoning & Garlic Powder – Adds a fragrant, robust layer of seasoning.

Fresh Parsley – For a pop of color and fresh herbal finish.

How To Make the Meatball Casserole

Step 1: Prep the Oven and Dish

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

Step 2: Layer the Base

Spread a thin layer of marinara sauce on the bottom of the dish. If using pasta, add a layer of cooked pasta next.

Step 3: Add Meatballs

Place cooked meatballs evenly across the dish. Nestle them gently into the pasta if using.

Step 4: Add Sauce and Season

Pour the remaining marinara sauce over the meatballs. Sprinkle with Italian seasoning and garlic powder.

Step 5: Top with Cheese

Generously layer shredded mozzarella and cheddar cheese over the top.

Step 6: Bake Until Bubbly

Bake uncovered for 25-30 minutes or until the cheese is melted, bubbly, and slightly golden.

Step 7: Garnish and Serve

Let cool slightly. Sprinkle chopped fresh parsley over the top before serving.

Serving and Storing Meatball Casserole

Serve hot straight from the oven, ideally with some crusty garlic bread or a light green salad. This dish is incredibly filling on its own, but sides can elevate it to a full Italian-style feast.

Store any leftovers in an airtight container in the refrigerator for up to 4 days. Reheat in the oven or microwave until warmed through. This casserole also freezes well—wrap tightly and store for up to 2 months.
