How to make Meatball Casserole

Now that you’ve gathered your ingredients, it’s time to make the meatball casserole. All you have to do is follow the steps below:

  1. First, prepare this cheesy meatball casserole by first preheating your oven to 400°F.
  2. In a casserole dish, combine the uncooked pasta with tomato sauce, Italian seasoning, salt, pepper, olive oil, and 1 1/2 cups of water. 
  3. Gently stir everything together, then arrange the meatballs over the top. Cover with aluminum foil and bake for 25-30 minutes. 
  4. Remove the foil, top with shredded mozzarella cheese, and return to the oven uncovered for 8-10 more minutes until the cheese melts.
  5. Garnish with fresh basil before serving hot.

Can you prepare the Meatball Casserole ahead of time?

You can easily prepare meatball casserole ahead of time for convenient meal prep. One option is to fully assemble the entire unbaked casserole up to 24 hours in advance. Follow all the steps by arranging the meatballs, then refrigerate until ready to bake. When you’re ready, bake it straight from the fridge, adding 5-10 minutes to the covered baking time. Remove the foil, top with cheese, and finish baking as directed.

Another method is to partially prep components separately ahead of time. Meatballs can be fully cooked and refrigerated or frozen up to 3 months in advance. The tomato sauce can be made up to 5 days ahead and refrigerated. 

On the day of baking, simply assemble the casserole with your prepped meatballs, sauce, and other ingredients, then bake according to instructions. Having these components ready gives you a head start for easy assembly later.

Can You Freeze Leftover Meatball Casserole for Later?

You can absolutely freeze leftover meatball casserole for later! Baked meatball casserole makes an excellent freezer meal. Allow any leftovers to cool completely, then transfer them to an airtight freezer-safe container or wrap tightly with aluminum foil. Properly stored, the frozen meatball casserole will keep for 2-3 months.

When ready to eat, there’s no need to thaw first. Simply remove the desired portion from the freezer and bake at 350°F (175°C) until heated through, about 1 hour if reheating from frozen. You can also reheat individual portions in the microwave.

The pasta may absorb more moisture when frozen, so have some extra sauce or broth on hand to help rehydrate it during reheating if needed. Freezing meatball casserole is a convenient way to enjoy future easy meals.
