Ingredients

  

  • 1.5 lbs ground beef
  • 6-7 cloves chopped garlic
  • 1/2 cup Italian breadcrumbs
  • 1/2 chopped onion
  • 1/4 cup chopped fresh parsley
  • 1/2 cup grated pecorino romano cheese
  • 2 eggs
  • 1 tsp salt and 1 tsp cracked black pepper
  • 15.5 oz. jar of marinara sauce or use homemade sauce
  • 2 cups freshly shredded mozzarella
  • Garnish: cracked black pepper and extra chopped fresh parsley
  • Nonstick spray or butter to grease the casserole dish

Instructions

 

  • Preheat the oven to 375°F (190°C).
  • In a large bowl, combine ground beef, chopped onion, minced garlic, chopped parsley, Italian breadcrumbs, grated pecorino romano, eggs, salt, and cracked black pepper.
  • Gently mix by hand until just combined—avoid overworking the meat so the meatballs stay tender.
  • Shape the mixture into about 1½-inch meatballs and arrange them in a greased casserole dish in a single layer.
  • Pour the marinara sauce over the meatballs, coating them evenly.
  • Sprinkle the shredded mozzarella over the sauced meatballs for a generous cheese layer.
  • Optional: sprinkle a little extra cracked black pepper and chopped parsley on top before baking.
  • Cover the dish tightly with foil and bake at 375°F for 25 minutes to cook the meatballs through.
  • Carefully remove the foil after the initial bake.
  • Return the casserole to the oven, uncovered, and bake another 15 minutes or until the cheese is melted and bubbly and the tops are lightly golden.
  • Let the casserole rest a few minutes, then serve with pasta, crusty bread, or a simple salad. Enjoy!
