Ingredients

25 ounces meatballs cooked (use your favorite, homemade, pork, chicken, meatless)
2 jars spaghetti sauce 24 ounce each
2 cups shredded mozzarella
¼ cup grated Parmesan
½ teaspoons dried basil
½ teaspoon dried oregano

Instructions

Preheat the oven to 375° F.
Spray a casserole dish with non-stick cooking spray. Place meatballs in the casserole dish. Pour the sauce over the meatballs, and give them a gentle stir so all the meatballs are covered with sauce. Sprinkle mozzarella, Parmesan, and dried herbs over the top of the sauce. Cover the dish with a lid or with tightly fitted aluminum foil.
Bake, covered, at 375° F for 30 minutes.
Uncover and bake, uncovered, 15 minutes or until cheese is melted, bubbly, and just beginning to brown a bit.

Notes

If your package of meatballs is a little bigger or smaller, no worries. A little more or a little less of any ingredient will be fine. You just want to make sure that all the meatballs are covered with sauce when they go in the oven.

Baked meatballs can be served as is, with a slice of garlic bread, over spaghetti, or as meatball sandwiches.

Make Ahead Instructions: Assemble the casserole a day in advance, refrigerate, and bake when ready to serve for a convenient make-ahead dinner.

Freezing Instructions: Assemble the casserole up until baking. Cover with a double layer of aluminum foil. Freeze up to 3 months. When you’re ready to cook it, thaw it in the fridge overnight. You can also bake it from frozen, bake covered for 1 & ½ hours, and uncovered for 15-20 minutes longer.

Leftovers: It makes great leftovers. Leftovers will keep in an airtight container in the fridge for up to a week. I usually pop it in the microwave to reheat, but it can be reheated in the oven as well at 350° F until hot.
