Ingredients:
- 1.5 lbs ground beef (80/20 lean-to-fat ratio)
- 1/2 cup Panko breadcrumbs
- 1 large egg, beaten
- 1/4 cup finely grated Parmesan cheese
- 2 cloves garlic, minced
- 2 tbsp fresh parsley, chopped
- 1 tsp kosher salt
- 1/2 tsp black pepper
- 1 cup beef broth
- 1/2 cup ketchup
- 2 tbsp Worcestershire sauce
- 1 tbsp brown sugar
- 1 tsp onion powder
Instructions:
- Combine the ground beef, Panko, egg, Parmesan, garlic, parsley, salt, and pepper in a large bowl. Note: Mix gently with your hands to avoid overworking the meat.
- Roll the mixture into 1.5 inch spheres. Note: Wet your hands slightly with water to prevent sticking.
- Place the rolled meatballs into the slow cooker in a single layer if possible.
- Whisk together the beef broth, ketchup, Worcestershire sauce, brown sugar, and onion powder in a separate jug.
- Pour the sauce evenly over the meatballs, ensuring every one is coated.
- Cover and cook on High for 4 hours or Low for 7 hours until the sauce is a deep, glossy mahogany.
- Gently stir the meatballs to coat them in the thickened glaze.
- If the sauce is too thin, remove the lid and cook on High for an additional 30 minutes until it reaches a syrupy consistency.
