Meatball Sandwich Casserole

Meatball Sandwich Casserole! All the delicious part of a meatball sub, but casserole style to feed a crowd, definitely a party-pleaser recipe.

Generally speaking, we make huge batches of meatballs a couple of times per year and then vacuum seal them in bags of 12-24 meatballs. They come in handy for throwing together meatball casseroles, like this one, adding to pasta dishes or skewering them on shish kebab sticks with veggies and grilling for a quick weeknight meal.

You’ll Need:
1 recipe frozen meatballs or 1 (2-3lb Bag of Frozen Meatballs)
1 jar of spaghetti sauce
1 cup mozzarella cheese, shredded
1 cup Italian blend cheese, shredded
1/2 cup Parmesan cheese, shredded
1 loaf of fresh Italian bread, sliced

Garlic Butter
1/2 stick butter, room temp
1 tbs minced garlic
1 tsp Italian seasoning

Mix the garlic, Italian seasoning, 2 tablespoons Parmesan cheese and butter together and spread them on the bread slices on 1 side only.

Arrange the bread standing up in the on the edges of a 9×13 baking dish.


In a saucepan heat the meatballs and sauce until warmed throughout, then pour the meatballs/sauce in the middle, add a layer of cheeses, more meatballs, then remaining cheese.

The bread should be standing up so it’ll get crispy.

Place in oven and bake for approximately 20 minutes at 375For until cheese is melted and bubbly.

Remove from oven, serve and enjoy!
