How To Make Cheesy Meatball Casserole

Enjoy a cheesy dish with this meatball casserole that’s made with seasoned meatballs in marinara sauce plus loads of mozzarella.

Preparation: 25 minutes
Cooking: 25 minutes
Total: 50 minutes



  • 3slicesbread
  • cupmilk
  • ½cupyellow onion,minced
  • 2tbspunsalted butter
  • 2lbsground beef,(80/20)
  • 2large eggs
  • ½tspkosher salt
  • ½tspcracked black pepper
  • 1tspWorcestershire sauce
  • 24ozmarinara sauce
  • 2cupsmozzarella cheese,shredded


  1. Preheat oven to 375 degrees F.

  2. In the bowl of a stand mixer, add the milk to the slices of bread.

  3. Melt 1 tablespoon butter in a pan and add the minced yellow onions. Cook them on medium-low until translucent but not browned. Remove from heat and let cool.

  4. In the bowl with the milk-soaked bread, add the rest of the meatball ingredients, including the cooked onions.

  5. Mix it on low until the bread is broken apart and the meat is combined with the ingredients. (Using the stand mixer and not hands helps keep the mixture cold and tender).

  6. Using a meatballer, ice cream scoop or hands scoop them into balls about the size of a ping pong ball.

  7. Melt the remaining butter in the pan and cook the meatballs on medium-high on all sides for around 2 to 3 minutes, getting a good sear on all sides, then remove from heat and set aside.

  8. Coat the bottom of a baking dish with a thin layer of marinara sauce. Place the meatballs evenly into the baking dish and pour the remaining marinara sauce over the top.

  9. Sprinkle the mozzarella cheese evenly over the baking dish.

  10. Cover the baking dish with aluminum foil and bake for 18 to 20 minutes.

  11. Increase the oven temperature to 425 degrees F, uncover the baking dish, and cook for an additional 5 minutes.
