Easy Dump and Bake Meatball Casserole Recipe

How to Make Dump and Bake Meatball Casserole

Step 1: Preheat and Prep

Start by preheating your oven to 375°F (190°C). Lightly grease a large casserole dish to keep everything from sticking, setting yourself up for an easy cleanup later.

Step 2: Mix Base Ingredients

In a large bowl, combine the cooked pasta or rice with marinara sauce, sautéed onions, garlic, and Italian seasoning. Stir until everything is evenly coated and fragrant, setting the rich flavor foundation for your casserole.

Step 3: Assemble Meatballs and Sauce

Dump the frozen or premade meatballs into the sauce mixture. Make sure they’re well distributed to avoid clumping in certain areas, then pour everything into the prepared casserole dish.

Step 4: Add Cheese Layers

Sprinkle shredded mozzarella evenly over the top, followed by a generous dusting of grated Parmesan. These cheeses will melt beautifully, creating a golden and bubbly crust once baked.

Step 5: Bake Until Bubbly

Place your casserole in the oven for about 30-35 minutes. Bake until the cheese is melted, bubbly, and starting to brown. Let it sit for 5 minutes before serving to ensure everything sets nicely.

Pro Tips for Making Dump and Bake Meatball Casserole

Use quality meatballs: Choosing flavorful, well-seasoned meatballs raises the dish’s overall taste with minimal effort.
Don’t overcook pasta: Slightly undercooking pasta before baking prevents it from becoming mushy.
Layer cheese thoughtfully: A blend of cheeses offers the best texture and flavor contrast.
Add fresh herbs after baking: Sprinkle fresh basil or parsley on top for an extra pop of color and freshness.
Cover with foil if needed: To avoid burning the cheese, tent the casserole with foil if it browns too quickly.
