I’m so excited to share this Dump-and-Bake Meatball Casserole Recipe with you because it’s truly a lifesaver on busy nights. Imagine tossing a few simple ingredients into a casserole dish, popping it in the oven, and knowing dinner will be ready with minimal fuss and maximum flavor.

What makes this Dump-and-Bake Meatball Casserole Recipe stand out for me is how all the flavors meld beautifully while it bakes — the tender meatballs soak up the sauce, the pasta cooks right in the dish, and the cheese melts into a gooey, irresistible topping. I love making this for casual family dinners or when friends drop by last minute because it’s just that easy to pull together and always a crowd-pleaser.

Ingredients You’ll Need

These ingredients come together to create a well-rounded, comforting dish that’s both filling and flavorful. You don’t need anything fancy — just pantry staples and a freezer staple (meatballs!). Choosing good-quality pasta sauce makes a big difference, so pick one you love or even make your own if you have a jar handy.

• Frozen meatballs: Using frozen saves time and they cook perfectly right in the casserole.
• Pasta sauce: A 24-ounce jar works great—go for your favorite marinara or tomato basil.
• Water: This helps cook the pasta right in the sauce, so no extra pots to clean up!
• Uncooked pasta (penne or rigatoni): These shapes hold sauce well and cook evenly in the oven.
• Shredded mozzarella cheese: For that melty, stretchy topping everyone loves.
• Grated Parmesan cheese: Adds a nice sharp punch and a golden finish.
• Fresh basil or parsley (optional): A sprinkle on top brightens the whole dish and gives it that fresh touch.

Variations

While I love the classic version, you can easily tailor this Dump-and-Bake Meatball Casserole Recipe to suit your tastes or dietary needs. I encourage you to get creative and make it your own!

• Spicy kick: Add some red pepper flakes or swap in spicy Italian sausage meatballs—I did this once and my family loved the extra punch!
• Vegetable upgrade: Stir in chopped spinach or mushrooms before baking for added nutrition and a flavor boost.
• Gluten-free: Use gluten-free pasta and meatballs to keep it friendly for those avoiding gluten.
• Dairy-free: Skip the cheese or use a plant-based alternative, and make sure the pasta sauce is dairy-free.

How to Make Dump-and-Bake Meatball Casserole Recipe

Step 1: Combine the Ingredients in Your Casserole Dish

Start by picking a casserole dish that’s big enough to hold everything comfortably — about 9×13 inches works perfectly. Pour your uncooked pasta into the dish, then scatter the frozen meatballs evenly over the top. Next, pour the entire jar of pasta sauce over the meatballs and pasta, then add the cup of water. Give everything a gentle stir to combine, making sure the pasta is mostly submerged (this helps it cook properly). Using frozen meatballs means no thawing required, which is a game-changer on hectic days!

Step 2: Bake Covered, Then Add Cheese

Cover your casserole with foil to trap the steam, which cooks that pasta evenly. Bake at 375°F (190°C) for about 35 minutes. After that, remove the foil, sprinkle shredded mozzarella and Parmesan cheeses over the top, and bake uncovered for another 10-15 minutes. This second bake lets the cheese melt into a bubbly, golden topping. A pro tip is to watch the edges — if the cheese browns too much, loosely cover it back with foil.

Step 3: Let It Rest and Garnish

When the cheese is perfectly melted and bubbly, pull the casserole from the oven and let it rest for about 5 minutes. This helps the sauce thicken slightly and makes serving easier. Before digging in, sprinkle fresh basil or parsley over the top to add a bright, fresh flavor and a pop of color — it’s such a nice finishing touch!

How to Serve Dump-and-Bake Meatball Casserole Recipe

Garnishes

I usually reach for fresh basil or chopped parsley because they bring a little life to the rich, cheesy casserole. Sometimes, I add a sprinkle of crushed red pepper or extra grated Parmesan on the side for those who want to customize their bites. It’s those small touches that make it feel just a bit more special.

Side Dishes

This meatball casserole pairs wonderfully with a simple green salad dressed lightly with lemon vinaigrette to cut through the richness. Garlic bread or a crusty baguette is perfect for mopping up any leftover sauce — I promise you’ll want every last bit! Roasted veggies like broccoli or asparagus make great easy sides, especially when you want to keep it balanced.

Creative Ways to Present

I once made this for a casual dinner party and served individual portions in mini cast iron skillets topped with fresh basil. It made the table look so inviting! You could also layer this in clear glass baking dishes or even serve alongside a DIY “meatball bar” with extra garnishes like olives, pickled peppers, or fresh herbs for a fun interactive meal.

Make Ahead and Storage

Storing Leftovers

I like to store leftover Dump-and-Bake Meatball Casserole Recipe in an airtight container in the fridge for up to 3 days. It reheats beautifully, so nothing goes to waste. Just be sure to cool it completely before covering to keep the flavors fresh.

Freezing

If you want to make double and freeze half, this casserole freezes well before baking. I assemble everything in a freezer-safe dish, cover tightly with foil, and freeze. When ready, I bake it straight from frozen—just add extra baking time and keep it covered until the pasta cooks through.

Reheating

To reheat, I usually pop leftovers into a 350°F oven for about 20 minutes, covered with foil so the cheese doesn’t dry out. Alternatively, the microwave works fine for a quick plate, but the oven method keeps the texture much nicer.
