How to Make Meatball Casserole:
Now that you have your ingredients ready, let’s dive into the steps for making this delightful Meatball Casserole. It’s as easy as pie, and you’ll feel like a culinary superstar!
Step 1: Preheat Oven
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish and set aside.
Step 2: Make the Meatballs
In a large mixing bowl, combine ground beef, breadcrumbs, Parmesan, milk, egg, garlic, Italian herbs, salt, and pepper. Mix until just combined to avoid dense meatballs. Form into small, evenly sized balls (about 1.5 inches in diameter).
Step 3: Cook the Meatballs
Heat a skillet over medium heat and add a little olive oil. Brown the meatballs on all sides for 5–7 minutes. They don’t need to be fully cooked through since they’ll bake in the casserole.
Step 4: Prepare the Sauce
In the same skillet, add olive oil if needed. Sauté onion and garlic until soft and fragrant, about 3–4 minutes. Stir in marinara sauce and Italian herbs, season with salt and pepper, and simmer for 5 minutes.
Step 5: Assemble the Casserole
Spread a thin layer of sauce in the bottom of the prepared baking dish. Layer half of the cooked pasta over the sauce, then evenly place the meatballs on top. Pour half of the remaining sauce over the meatballs and pasta. Sprinkle half of the mozzarella and Parmesan cheese. Repeat layers with the remaining pasta, sauce, and cheeses.
Step 6: Bake
Cover the casserole with foil and bake in the preheated oven for 20 minutes. Remove foil and bake an additional 10–15 minutes until the cheese is melted, golden, and bubbly.
Step 7: Garnish and Serve
Remove from the oven, let cool for 5 minutes, then sprinkle with fresh basil or parsley. Serve hot and watch everyone go back for seconds.
Tips for Success:
- Avoid overmixing the meatball mixture to keep them tender.
- Slightly undercook meatballs in the skillet—they finish cooking in the oven.
- Use freshly grated Parmesan and mozzarella for the best flavor and melt.
- For added depth, add a pinch of red pepper flakes to the sauce for a subtle kick.
- Make-ahead tip: Assemble the casserole and refrigerate for up to 24 hours before baking.

Equipment Needed:
- Large mixing bowl
- Skillet
- Baking dish (9×13-inch)
