Equipment

  • Slow Cooker
  • Mixing Bowl

Ingredients

Cheese

  • 8 oz Fresh mozzarella, cut into 1/2-inch cubes

Meat

  • 1 lb Ground beef
  • 1 lb Ground Italian sausage

Seasonings

  • 1/2 tsp Garlic powder
  • 2 tsp Salt
  • 1 tsp Black pepper

Binders

  • 1 cup Breadcrumbs
  • 1/4 cup Finely grated Parmesan cheese
  • 2 large Eggs
  • 1/2 cup Whole milk
  • 1/2 cup Fresh parsley, chopped

Sauce

  • 24 oz Prego Traditional sauce (or similar marinara)

Instructions

  • In a large bowl, mix together ground beef, sausage, garlic powder, salt, pepper, breadcrumbs, Parmesan, eggs, milk, and parsley until well combined.
  • Scoop about 1.5 inches of the meat mixture and shape into a ball.
  • Press a mozzarella cube into the center of the meatball and roll to seal it inside.
  • Pour 1/3 of the marinara sauce into the bottom of the slow cooker.
  • Layer in the meatballs, then pour more sauce over them. Repeat if needed until all meatballs and sauce are used.
  • Cover and cook on High for 2 to 2.5 hours, or until meatballs are fully cooked and cheese is melted inside.
  • Serve over pasta, in subs, or with a side of garlic bread. Enjoy!

Notes

Make sure to seal each meatball well to prevent cheese from leaking. You can use ground turkey or chicken as a lighter alternative. For extra spice, add red pepper flakes to the meat mix. These meatballs are also great for meal prep and freeze well in sauce.
