Ingredients

Scale
  • 1 lb (450 g) ground beef (or mix of beef and pork)
  • 1 large egg
  • ½ cup (50 g) breadcrumbs
  • ¼ cup (25 g) grated Parmesan cheese
  • 1 tsp garlic powder
  • 1 tsp onion powder
  • ½ tsp salt
  • ¼ tsp black pepper
  • 2 tbsps chopped parsley (optional)
  • 2 large onions, thinly sliced
  • 2 tbsps unsalted butter
  • 1 tbsp olive oil
  • 1 tsp sugar
  • 1 tsp garlic, minced
  • 2 cups (480 ml) beef broth
  • 1 tbsp Worcestershire sauce
  • 1 tbsp cornstarch mixed with 2 tbsps water (slurry)
  • ½ tsp thyme (optional)
  • ¼ cup (60 g) shredded Gruyere or Swiss cheese (for topping, optional)

Instructions

  1. Meatball Preparation: Thoroughly mix ground beef with breadcrumbs, Parmesan, egg, garlic and onion powders, salt, pepper, and parsley until ingredients bind seamlessly into a cohesive mixture.
  2. Shaping and Positioning: Carefully form compact, uniform meatballs roughly one inch in diameter, arranging them strategically on a clean surface.
  3. Slow Cooker Setup: Lightly spray the slow cooker’s interior with cooking spray and spread caramelized onions across the base to create a flavorful foundation.
  4. Assembly and Liquid Infusion: Gently place meatballs over the onion layer, ensuring even distribution, then methodically pour French onion soup to thoroughly coat and permeate the meat.
  5. Cooking Process: Secure the slow cooker lid and simmer on low temperature for 4-5 hours, allowing flavors to develop and meatballs to become tender and succulent.
  6. Serving Presentation: Carefully transfer meatballs to a serving platter, optional garnish with fresh parsley and melted Gruyère cheese to elevate the dish’s visual and gustatory appeal.

Notes

  • Ensure Meat Moisture: Mix ingredients gently to prevent dense, tough meatballs; overmixing can make them tough and dry.
  • Control Meat Fat Content: Use ground beef with 80/20 lean-to-fat ratio for juicy, flavorful meatballs that won’t become crumbly or dry.
  • Prevent Sticking: Lightly spray slow cooker with cooking spray and avoid overcrowding meatballs for even cooking and easy removal.
  • Cheese Melting Technique: Add Gruyère cheese during last 15-20 minutes of cooking or broil briefly to achieve perfect golden, bubbly cheese topping.
  • Prep Time: 20 minutes
  • Cook Time: 6-8 hours (low) or 3-4 hours (high)
