Ingredients:

1 pound ground beef (or a combination of ground beef and ground pork)

  • ½ cup breadcrumbs (plain or Italian seasoned)
  • ½ cup grated Parmesan cheese
  • ¼ cup finely chopped onion
  • 2 large cloves garlic, minced
  • 1 large egg, beaten
  • ½ cup milk
  • 2 tablespoons Worcestershire sauce
  • 1 tablespoon dried oregano
  • 1 teaspoon Italian seasoning
  • ½ teaspoon salt
  • ¼ teaspoon black pepper

  • Instructions:

    1. Combine Dry Ingredients: In a large bowl, whisk together the breadcrumbs, Parmesan cheese, oregano, Italian seasoning, salt, and pepper.

    2. Mix Wet Ingredients: In a separate bowl, whisk together the milk, egg, Worcestershire sauce, and minced garlic.

    3. Combine Everything: Add the ground beef and chopped onion to the dry ingredients. Pour in the wet ingredients and mix gently with your hands until just combined. Do not overmix! Overmixing can make the meatballs tough.

    4. Shape the Meatballs: Using a spoon or your hands, scoop out the meatball mixture and roll it into 1-inch balls.

    5. Crockpot Time: Pour your favorite marinara sauce (enough to cover the bottom of the crockpot) into the crockpot. Gently place the meatballs in a single layer on top of the sauce.

    6. Cook Low and Slow: Cover the crockpot and cook on LOW for 6-8 hours, or on HIGH for 4-5 hours, until the meatballs are cooked through and reach an internal temperature of 160°F.

    7. Serve and Enjoy: Drain any excess grease from the crockpot (optional). Serve the meatballs warm on toasted sub rolls with your favorite toppings like melted provolone cheese, marinara sauce, chopped red onion, green peppers, and mozzarella sticks.
