How to Make Dump and Bake Meatball Casserole
- Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch casserole dish to prevent sticking.
- Place the uncooked penne pasta evenly in the casserole dish, then add the frozen meatballs on top.
- Pour the marinara sauce evenly over the meatballs and pasta. Sprinkle the Italian seasoning, garlic powder, and crushed red pepper flakes if using.
- Pour 2 cups of water gently around the edges to help the pasta cook evenly without washing away the sauce.
- Cover the casserole tightly with aluminum foil and bake for 35 minutes.
- Remove the foil, sprinkle the mozzarella and Parmesan cheeses evenly over the top, and bake uncovered for an additional 10 minutes until the cheese is melted and bubbly.
- Let the casserole rest for 5 minutes after baking to thicken slightly. Garnish with chopped fresh parsley before serving.
Tips for the Best Results
- Use frozen cooked meatballs to save time and ensure even cooking.
- Do not stir after baking starts to keep pasta from becoming mushy.
- If you like a creamier texture, stir in 1/4 cup of heavy cream or ricotta cheese before baking.
- Make sure to cover the casserole tightly with foil to trap steam and cook the pasta thoroughly.
- For extra flavor, add sliced mushrooms or bell peppers in the casserole before baking.
Storage and Reheating
Store any leftover dump and bake meatball casserole in an airtight container in the refrigerator for up to 3 days. It reheats well in the oven or microwave.
For longer storage, freeze the casserole in a freezer-safe container for up to 2 months. Thaw overnight in the refrigerator and reheat covered at 350°F until warmed through.
Frequently Asked Questions
Can I use fresh meatballs instead of frozen?
Yes, fresh meatballs can be used, but be sure they are fully cooked before adding to the casserole to ensure safety and proper texture. Adjust the baking time accordingly if needed.
What pasta works best for this casserole?
Short pasta shapes like penne, rigatoni, or rotini work best because they hold sauce well and cook evenly in a casserole.
Can I make this casserole ahead of time?
You can assemble the casserole a few hours ahead and refrigerate it covered, then bake just before serving. Avoid baking and refrigerating as reheating may dry out the pasta.
Is this recipe gluten-free?
To make it gluten-free, use gluten-free pasta and ensure the meatballs and marinara sauce are gluten-free as well. Many brands offer gluten-free options.
