Ingredients

Scale

Meat and Protein:

  • 1 pound (454 grams) ground beef
  • 1 egg, lightly beaten

Cheese:

  • 1/4 cup (25 grams) grated Parmesan cheese
  • 1 1/2 cups (170 grams) shredded Gruyere or Swiss cheese (optional)

Herbs, Spices, and Seasonings:

  • 1 tablespoon Worcestershire sauce
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper

Binding and Base Ingredients:

  • 1/2 cup (60 grams) breadcrumbs
  • 2 tablespoons (30 milliliters) olive oil

Liquid and Soup Components:

  • 2 cups (480 milliliters) beef broth
  • 1 packet French onion soup mix

Vegetables:

  • 2 large onions, thinly sliced

Optional Garnish:

  • Fresh parsley

Instructions

  1. Craft succulent meatballs by blending ground beef with breadcrumbs, egg, Parmesan, Worcestershire sauce, garlic powder, onion powder, salt, and pepper. Gently shape mixture into uniform 1-inch spheres.
  2. Warm olive oil in a skillet over medium heat. Carefully brown meatballs on all surfaces for approximately 4-5 minutes, ensuring golden exterior but not fully cooked. Transfer seared meatballs to crockpot.
  3. Utilize the same skillet to caramelize sliced onions, stirring periodically for 5-7 minutes until soft and golden. Deposit onions into crockpot alongside meatballs.
  4. Whisk beef broth with French onion soup mix, creating a rich liquid seasoning. Pour this aromatic mixture evenly over meatballs and onions.
  5. Secure crockpot lid and slow cook: 4-6 hours on low setting or 2-3 hours on high setting. Ensure meatballs reach tender, thoroughly cooked consistency.
  6. During final 15 minutes, generously sprinkle Gruyere or Swiss cheese atop meatballs. Allow cheese to melt completely by maintaining covered crockpot.
  7. Plate meatballs with optional fresh parsley garnish. Accompany with mashed potatoes, rice, or crusty bread for a hearty meal.

Notes

  • Sear meatballs thoroughly to lock in juices and create a delicious golden-brown exterior that enhances flavor and texture.
  • Use ground beef with 80/20 fat content for optimal moisture and richness in the meatballs, preventing them from becoming dry during slow cooking.
  • Make the dish gluten-free by substituting breadcrumbs with almond flour or gluten-free breadcrumbs, ensuring everyone can enjoy this comforting meal.
  • Prepare meatballs ahead of time and freeze uncooked for quick weeknight dinners, maintaining the same delicious taste and quality when slow-cooked from frozen.
