Ingredients

Scale

Meat and Protein:

  • 1 pound (0.45 kilogram) ground beef
  • 1 large egg
  • 1 ½ cups shredded Gruyère cheese
  • ¼ cup grated Parmesan cheese

Seasonings and Herbs:

  • 2 cloves garlic, minced
  • 1 tablespoon Worcestershire sauce
  • 1 teaspoon dried parsley
  • ½ teaspoon onion powder
  • ½ teaspoon salt
  • ¼ teaspoon black pepper
  • 1 teaspoon dried thyme
  • ½ teaspoon garlic powder

Base and Binding Ingredients:

  • ½ cup breadcrumbs
  • 2 large yellow onions, thinly sliced
  • 3 tablespoons unsalted butter
  • 1 (10.5 ounces) can condensed French onion soup
  • 1 cup beef broth

Instructions

  1. Combine ground beef with breadcrumbs, egg, garlic, thyme, salt, and pepper in a mixing bowl. Gently form uniform meatballs, ensuring they are compact but not overly dense.
  2. Warm olive oil in a skillet over medium heat (around 350°F). Carefully brown meatballs on all sides until golden, creating a flavorful exterior crust.
  3. Transfer browned meatballs into the crockpot, maintaining their shape and integrity.
  4. Using the same skillet, sauté sliced onions until they become deeply caramelized and rich golden brown, approximately 8-10 minutes.
  5. Add caramelized onions directly into the crockpot, spreading them evenly around the meatballs.
  6. Pour beef broth and sprinkle French onion soup mix over the meatballs and onions, ensuring complete coverage.
  7. Cover crockpot and slow cook on low temperature for 6-8 hours or high temperature for 3-4 hours, allowing flavors to meld and meatballs to become tender.
  8. During the final 30 minutes of cooking, generously top meatballs with shredded Gruyère or Swiss cheese, allowing it to melt completely.
  9. Once cooking is complete, garnish with fresh parsley and serve immediately over mashed potatoes, steamed rice, or alongside crusty artisan bread.

Notes

  • Ensure meat is freshly ground for maximum flavor and tender texture.
  • Browning meatballs before slow cooking creates a delicious caramelized exterior and locks in juices.
  • Use low-sodium beef broth to control salt levels and prevent overly salty dish.
  • For gluten-free version, replace breadcrumbs with almond flour or gluten-free breadcrumbs.
