Step‑by‑Step Instructions for Dump and Bake Meatball Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 425°F (220°C). This high temperature will ensure that your Dump and Bake Meatball Casserole gets a nice, bubbly finish. While the oven heats, lightly grease a 9×13-inch baking dish to prevent sticking and make cleanup a breeze.
Step 2: Combine Ingredients
In your greased baking dish, combine the uncooked penne pasta, marinara sauce, and your choice of water or broth. Add the frozen meatballs, then sprinkle in the Italian seasoning, along with optional garlic powder and onion powder for extra flavor. Stir everything together until all ingredients are well mixed and the pasta is submerged in the sauce.
Step 3: Bake Covered
Cover the baking dish tightly with aluminum foil and place it in the preheated oven. Bake for 35–40 minutes, allowing the pasta to cook through and absorb the rich flavors of the sauce. You’ll know it’s ready when the pasta is tender and the meatballs are warmed through.
Step 4: Add Cheese Topping
Once the initial baking time is up, carefully remove the foil—watch out for hot steam! Sprinkle a generous layer of shredded mozzarella cheese and grated Parmesan cheese evenly over the top of the casserole. This will create a deliciously gooey and golden crust.
Step 5: Bake Uncovered
Return the uncovered casserole to the oven and bake for an additional 10–15 minutes. Keep an eye on it, and look for the cheese to melt, bubble, and turn a lovely golden brown. This adds a beautiful finish to your Dump and Bake Meatball Casserole.
Step 6: Let it Rest
After baking, remove the casserole from the oven and let it rest for 5–10 minutes. This resting period allows the flavors to meld and makes serving easier, ensuring each slice holds together beautifully. Now you’re ready to dish out a delicious, hearty meal!

Make Ahead Options
These Dump and Bake Meatball Casseroles are fantastic for meal prep! You can assemble the casserole up to 24 hours ahead of time by combining all the ingredients in your baking dish, covering it tightly with foil, and refrigerating it until you’re ready to bake. This keeps the pasta submerged in the marinara, ensuring it absorbs all those delicious flavors. When you’re ready to enjoy your meal, simply preheat the oven and bake the dish as directed.
