How to Make Meatball Casserole

This dish couldn’t possibly be easier!

  1. Prepare. Preheat the oven to 425°F. Grease a 9×13-inch baking dish. 2. Mix the ingredients. In the prepared baking dish, mix together the uncooked pasta, water, pasta sauce, thawed meatballs, salt, and red pepper flakes (if using). Stir until evenly combined. 3. Bake. Cover the baking dish tightly with aluminum foil and bake for 35 minutes. 4. Check for pasta doneness. After 35 minutes, remove from the oven and stir. If the pasta is still a bit firm, cover and return to the oven for 5 more minutes. 5. Add the cheese topping. Remove the foil and sprinkle the shredded mozzarella evenly over the top of the casserole. 6. Bake again. Return to the oven uncovered and bake for an additional 5-10 minutes, until the cheese is melted and bubbly. 7. Cool before serving. Remove from the oven and let cool for 10-15 minutes before serving. The sauce will thicken as it cools.

Tips For the Best Meatball Casserole

These tried-and-true tips will make your casserole shine.

  • Make it extra bubbly. For an extra golden and bubbly cheese topping, broil the casserole for the last 1-2 minutes of baking. Keep a close eye on it to prevent burning.
  • Give it a rest. Allow the casserole to cool for 10-15 minutes before serving. This gives the sauce a chance to thicken and the flavors to meld.
  • Select your sauce. Marinara is an excellent choice for its rich, slow-simmered taste. For a spicier kick, try arrabbiata sauce or add red pepper flakes.
  • Vary it up. Mix in sautéed onions, bell peppers, or mushrooms for added veggie goodness. Or use Italian sausage or mini ravioli in place of meatballs.
  • Amp up the garnishes. Add a sprinkle of fresh chopped parsley and grated Parmesan cheese before serving.
