Flavor-packed ground beef meatballs are stuffed with mozzarella cheese, baked, and finished in the slow cooker. This meal produces nicely browned, tender meatballs, with a cheesy inside.
2pounds 85/15 ground beef leaner is better for these to prevent too much excess grease.
1cupItalian seasoned bread crumbs
1teaspoon Worcestershire sauce
3cloves fresh garlic pressed
¼cuponion minced
salt & pepper to taste
¼cupketchup
¼cup mustard
1largeegg
8ounces mozzarella cheese cubed or use pearls
36ounces 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.
