- Uncooked pasta: Penne or rotini work perfectly, absorbing the sauce while holding their shape and adding satisfying texture.
- Marinara sauce: This tomato base infuses the casserole with richness and a comforting familiar Italian flavor.
- Water or beef broth: Helps cook the pasta evenly in the oven and deepens the overall savory profile.
- Italian seasoning: A blend of herbs that brings a lovely aromatic touch and ties the whole dish together.
- Garlic powder: Adds subtle warmth and depth without the hassle of mincing fresh garlic.
- Onion powder: Brings a mild, sweet essence that complements both the meatballs and sauce.
- Red pepper flakes (optional): A pinch adds just the right amount of heat if you want a little kick.

How to Make Dump and Bake Meatball Casserole Recipe
Step 1: Preheat and prepare your dish
Start by heating your oven to 425°F (220°C). Grease a 9×13 inch baking dish lightly with cooking spray or butter to prevent sticking and make serving easier. This simple prep sets the stage for the casserole to come together seamlessly.
Step 2: Mix your main ingredients
Dump the frozen meatballs into the baking dish, then add the uncooked pasta. Pour over the marinara sauce and your choice of water or beef broth. Sprinkle in the Italian seasoning, garlic powder, onion powder, red pepper flakes if using, plus a pinch of salt and pepper. Give everything a good stir to distribute all these flavors evenly throughout the casserole.
Step 3: Bake covered
Seal the baking dish tightly with aluminum foil to lock in moisture, then let it bake for 30 minutes. This step allows the pasta to cook fully while the meatballs warm through, soaking up all those savory juices.
Step 4: Add cheese and finish baking
Take off the foil and stir the casserole gently to mix up the layers. Now scatter the shredded mozzarella cheese evenly over the surface. Return the dish to the oven, uncovered, and bake for another 10 to 15 minutes until the cheese is melted, bubbling, and showing beautiful golden spots.
Step 5: Cool and garnish
Once out of the oven, allow the casserole to sit for a few minutes to settle and make serving easier. Sprinkle fresh chopped parsley on top for a vibrant, fresh finish that brightens each hearty bite.
How to Serve Dump and Bake Meatball Casserole Recipe

Garnishes
A sprinkle of fresh parsley is classic, but you can also add grated Parmesan or a few torn basil leaves for extra aroma and flavor. These simple touches make your casserole feel extra special without much effort.
Side Dishes
This casserole pairs beautifully with a crisp green salad dressed lightly in vinaigrette, steamed veggies like broccoli or green beans, or even some garlic bread. These sides balance the richness and make your meal complete.
Creative Ways to Present
Consider serving the casserole in individual ramekins for a lovely presentation at dinner parties. Or layer it with different cheeses like provolone and cheddar to mix up the flavors. No matter how you plate it, this dish is sure to impress.
Make Ahead and Storage
Storing Leftovers
Let the casserole cool completely before transferring leftovers into airtight containers. Refrigerate for up to 3 to 4 days, making it a perfect ready-to-eat option when time is tight later in the week.
Freezing
This Dump and Bake Meatball Casserole Recipe freezes wonderfully. Simply cover tightly with plastic wrap and aluminum foil or use freezer-safe containers. It can be frozen for up to 2 months without losing its delicious flavor and texture.
Reheating
To reheat, thaw overnight in the fridge if frozen, then warm in the oven at 350°F (175°C) until heated through and bubbly again, about 20 minutes. You can also microwave individual portions for a quick lunch or dinner fix.
FAQs
Can I use homemade meatballs instead of frozen?
Absolutely! Homemade meatballs work great here. Just make sure they’re fully cooked before adding them to the casserole to ensure everything finishes cooking evenly in the oven.
What types of pasta work best for this casserole?
Penne and rotini are ideal because their shapes hold onto the sauce well, but feel free to experiment with other short pasta like rigatoni or fusilli depending on what you have on hand.
Is it okay to use water instead of broth?
Yes, water works fine, especially when the marinara sauce is flavorful, but using beef broth adds an extra savory depth that can make the casserole even more delicious.
Can I make this recipe gluten-free?
Definitely! Just swap out regular pasta for your favorite gluten-free pasta variety and ensure your meatballs and marinara sauce are gluten-free. The rest of the ingredients are naturally safe.
How can I make this casserole spicier?
If you like heat, increase the red pepper flakes or add a dash of hot sauce to the sauce mixture before baking. You could also top with sliced jalapeños just before serving for an extra kick.
