Method
Preparation
- In a large bowl, combine ground beef, breadcrumbs, Parmesan cheese, egg, onion, garlic, Worcestershire sauce, salt, and pepper. Mix gently until just combined.
- Shape the mixture into meatballs about 1 inch in diameter, yielding approximately 20-24 meatballs.
- Lightly spray the slow cooker with cooking spray.
Cooking
- Place the meatballs in a single layer at the bottom of the slow cooker.
- In a bowl, whisk together the beef broth and onion soup mix. Pour this mixture over the meatballs.
- Cover and cook on low for 6-8 hours or on high for 3-4 hours.
- If using mushrooms, add them in the last hour of cooking.
Serving
- Serve the meatballs warm over mashed potatoes or rice, drizzling the gravy on top.
Notes
Chilling the meat mixture for 30 minutes before forming the meatballs can help hold their shape. For extra flavor, you may sear the meatballs in a skillet before slow cooking.
