Ingredients

Meatballs

  • 1 lb ground beef

  • 2 lbs Italian sausage

  • 2 eggs

  • 1 cup breadcrumbs

  • ½ cup Parmesan cheese

  • 1 small onion, finely chopped

  • 2 cloves garlic, minced

  • 1/3 cup fresh parsley, chopped

  • 1 tsp salt

How to Make Slow Cooker Italian Meatballs

1. Mix the Meatball Mixture

In a large bowl, combine ground beef, Italian sausage, eggs, breadcrumbs, Parmesan, onion, garlic, parsley, salt, pepper, oregano, basil, and red pepper flakes. Mix gently until just combined. Do not overmix.

2. Shape the Meatballs

Roll mixture into evenly sized 1.5-inch meatballs and place on a tray.

3. Brown the Meatballs (Recommended Step)

Heat olive oil in a large skillet or stovetop slow cooker pan over medium-high heat. Brown meatballs on all sides until golden for extra flavor and texture.

4. Slow Cook

Transfer meatballs to the slow cooker and pour marinara sauce over the top.

Cook on LOW for 4–6 hours, or until meatballs are tender and fully cooked (internal temperature 165°F).

5. Serve

Serve over spaghetti, rigatoni, creamy polenta, or in toasted sub rolls. Top with Parmesan and fresh parsley.
