Equipment

  • 6-quart slow cooker
  • large, rimmed baking sheet
  • parchment paper
  • wooden spoon
  • large mixing bowl
  • garlic press
  • double-tablespoon sized cookie scooper
  • Cutting board
  • chef's knife
  • measuring spoons & cups

Ingredients

  • 2 pounds 85/15 ground beef leaner is better for these to prevent too much excess grease.
  • 1 cup Italian seasoned bread crumbs
  • 1 teaspoon Worcestershire sauce
  • 3 cloves fresh garlic pressed
  • ¼ cup onion minced
  • salt & pepper to taste
  • ¼ cup ketchup
  • ¼ cup mustard
  • 1 large egg
  • 8 ounces mozzarella cheese cubed or use pearls
  • 36 ounces marinara sauce your choice of flavors

Instructions

  • Add all ingredients with the exception of the cheese into a large mixing bowl. Using gloved, or clean hands mix the beef, egg, and seasonings well to fully combine.
  • Form 2 tablespoon-sized balls and line them on a parchment-lined, rimmed baking sheet.
  • Gently depress each meatball to flatten. Add a cube of cheese to the center, and wrap the meat around the cheese to form a ball.
  • Bake meatballs for 15 minutes at 375°F. This will help the meatballs brown and keep their shape.
  • Add sauce (optional) and meatballs to the slow cooker and cook on low for 2-4 hours. Serve warm with your choice of sides.
