Description

These slow cooker mozzarella stuffed meatballs are juicy, tender meatballs filled with melted mozzarella and simmered in a rich tomato sauce, perfect for an easy and comforting dinner.


Ingredients

  • 1 lb ground beef
  • 1/2 cup breadcrumbs
  • 1/4 cup grated Parmesan cheese
  • 1 large egg
  • 2 cloves garlic, minced
  • 1 tsp Italian seasoning
  • 1/2 tsp salt
  • 1/4 tsp black pepper
  • 4 oz mozzarella cheese, cut into small cubes
  • 3 cups marinara sauce (store-bought or homemade)
  • Fresh parsley, chopped (optional, for garnish)

Instructions

  1. In a large bowl, combine the ground meat, breadcrumbs, Parmesan, egg, garlic, Italian seasoning, salt, and pepper. Mix until just combined.
  2. Take a scoop of the mixture, flatten slightly, place a cube of mozzarella in the center, and form the meat around it to seal completely.
  3. Place the stuffed meatballs in the bottom of the slow cooker.
  4. Pour the marinara sauce evenly over the meatballs, ensuring they are fully covered.
  5. Cover and cook on low for 4–6 hours or on high for 2–3 hours, until meatballs are cooked through and cheese is melted inside.
  6. Serve warm, optionally garnished with chopped fresh parsley.

Notes

  • Chilling the meatballs before cooking helps prevent cheese from leaking out.
  • Use low-moisture mozzarella for best results.
  • Try ground turkey or chicken for a lighter version.
  • Freeze cooked meatballs in sauce for up to 3 months.
