How to Make Meatball Casserole
Step 1. Make the Meatballs
In a large mixing bowl, combine the ground beef, breadcrumbs, Parmesan, egg, garlic powder, onion powder, Italian seasoning, salt, and pepper. Mix everything gently with your hands until it’s just combined. Don’t overmix or the meatballs can get tough.
Step 2. Shape and Cook the Meatballs
Roll the meat mixture into small balls about the size of a golf ball. Place them on a baking sheet or skillet. Bake them at 375°F (190°C) for 15–20 minutes until they’re cooked through and slightly browned.
Step 3. Prepare the Pasta
While the meatballs bake, cook the pasta in boiling water according to the package directions. Drain the pasta and set it aside.

Step 4. Assemble the Casserole
In a 9×13 baking dish, spread a thin layer of marinara sauce. Add the cooked pasta, then place the meatballs on top. Pour the rest of the sauce over everything. Sprinkle mozzarella and Parmesan cheese on top, and add any optional veggies if you want.
Step 5. Bake the Casserole
Cover the baking dish with aluminum foil and bake at 375°F (190°C) for 20 minutes. Remove the foil and bake for another 10 minutes until the cheese is melted and bubbly.
Step 6. Cool and Serve
Let the casserole cool for 5–10 minutes before serving so the sauce can thicken. Then slice it like a big cheesy pie and enjoy!
