How to Make Meatball Casserole: Step-by-Step Guide
This section is where the magic happens. Follow these simple steps, and you’ll have a golden, bubbling casserole in no time.
Step 1: Prep the Meatballs
Preheat your oven to 190°C (375°F). Gather ground meat, breadcrumbs, egg, garlic, onion, salt, pepper, and Italian seasoning. Lightly grease a baking dish and set it aside.
Step 2: Mix and Form the Meatballs
In a large bowl, combine the ground meat, breadcrumbs, egg, minced garlic, finely chopped onion, and seasonings. Mix gently until just combined—avoid overmixing to keep the meatballs tender. Roll into evenly sized meatballs.
Step 3: Brown the Meatballs (Or Bake)
For extra flavor, brown the meatballs in a skillet with a little oil over medium heat for 5–7 minutes, turning to brown all sides. Alternatively, bake them on a tray for 12–15 minutes until lightly cooked through.
Step 4: Assemble the Casserole
Spread a layer of marinara sauce in the prepared baking dish. Arrange the meatballs evenly, then pour more sauce over the top. Sprinkle generously with shredded mozzarella and Parmesan cheese.
Step 5: Bake to Perfection
Cover with foil and bake for 20 minutes. Remove the foil and bake for another 10 minutes until the cheese is bubbly and lightly golden. Let rest for a few minutes before serving.
Tips for the Best Meatball Casserole
Want your casserole to turn out like a restaurant-quality dish every time? Let’s go over a few tips and tricks that can elevate your meatball casserole game.
Don’t Skip the Seasoning
Seasoning is everything. Even though marinara sauce is flavorful, your meatballs need their own punch of flavor. Garlic, herbs, Parmesan, salt, and pepper should be well-balanced in the meat mix. If you’re unsure, cook a small test meatball in a pan and adjust the seasoning if needed.
Use Freshly Grated Cheese
Pre-shredded cheese is convenient, but it often contains anti-caking agents that prevent smooth melting. If you want that gooey, stretchy cheese pull, grate fresh mozzarella and Parmesan. It’s worth the extra couple of minutes, trust me.
Layer Smartly
When layering, make sure your sauce touches every corner of the pasta. It prevents dry bites and helps the dish cook evenly. Also, layer the cheese in stages so it melts beautifully throughout, not just on top.
Avoid Overcooking the Pasta
Since the pasta is baked again in the oven, undercook it slightly before mixing it into the casserole. Think al dente—firm to the bite. Overcooked pasta will turn mushy, and no one wants that in a baked dish.
Let it Rest
After baking, give the casserole at least 10 minutes to cool slightly before serving. It not only makes slicing and serving easier, but the flavors also settle and intensify.
Bonus Tip: Add a Crunchy Topping
Want a bit of texture? Mix breadcrumbs with a tablespoon of melted butter and a sprinkle of Parmesan. Add this to the top before the last 10 minutes of baking for a crispy golden crust.
Make-Ahead and Freezer Instructions
Busy week ahead? No problem. This casserole is a meal-prep dream. You can make it ahead or freeze it, and it still tastes incredible when reheated.
How to Prep Ahead
- Make the Meatballs Ahead: You can roll and refrigerate raw meatballs up to 24 hours before cooking. Or fully cook them and store in the fridge for up to 3 days.
- Assemble the Whole Casserole: You can assemble the entire dish, cover it tightly with foil or plastic wrap, and refrigerate for up to 2 days. Just remove from the fridge 30 minutes before baking to bring it closer to room temp.
- Sauce & Pasta: Cook the pasta and warm up your sauce beforehand, so you’re not juggling everything at once.
How to Freeze and Reheat
To Freeze (Unbaked): Assemble the casserole in a freezer-safe dish. Wrap it tightly in plastic wrap and then in aluminum foil. Label with the date. It can be frozen for up to 3 months.
To Freeze (Baked): Let the cooked casserole cool completely. Then wrap and freeze as described above.
To Reheat from Frozen: Remove all wrapping, cover loosely with foil, and bake at 375°F (190°C) for 45–60 minutes until heated through. You can also thaw overnight in the fridge for faster reheating.
