Ingredients

Scale

Meatballs

  • 1 lb Ground Beef (Use lean ground beef for a healthier option.)
  • 1 cup Breadcrumbs (Use gluten-free for a gluten-free option.)
  • 1 large Egg
  • 2 cloves Minced Garlic (Use fresh for the best flavor.)
  • 1 tsp Salt (Adjust according to dietary preferences.)
  • 1/2 tsp Black Pepper (Freshly ground is recommended.)
  • 2 tbsp Olive Oil (Can substitute with butter for richer flavor.)

French Onion Sauce & Topping

  • 2 large Onions (Sweet onions like Vidalia are ideal.)
  • 2 cups Beef Broth (Low-sodium versions are preferable.)
  • 1 tsp Fresh Thyme (Dried thyme can be used as a substitute.)
  • 1 cup Gruyere Cheese (Can substitute with Swiss cheese.)


Instructions

  1. Prepare the Onions: Peel and thinly slice the onions. In a large skillet over medium heat, add olive oil and sauté the onions until they become deeply caramelized and golden brown, about 20-30 minutes, stirring occasionally to prevent burning.
  2. Make the Meatball Mixture: In a large bowl, combine ground beef, breadcrumbs, egg, minced garlic, salt, and black pepper. Mix gently until just combined; avoid overmixing to keep meatballs tender.
  3. Form the Meatballs: Shape the mixture into 6 equal-sized meatballs, roughly 2 inches in diameter, ensuring they are compact but not too dense.
  4. Sear the Meatballs: Heat a skillet with 1 tablespoon of olive oil over medium-high heat. Sear the meatballs on all sides until browned, about 2-3 minutes per side. This step locks in juices and adds flavor.
  5. Transfer to Crock Pot: Place the browned meatballs into the slow cooker. Add the caramelized onions, beef broth, and fresh thyme over the meatballs, ensuring they are mostly submerged in the liquid.
  6. Cook Slowly: Cover and cook on low heat for 4 hours (240 minutes) until meatballs are cooked through and flavors meld beautifully.
  7. Add Cheese and Finish: About 15 minutes before serving, sprinkle the Gruyere cheese evenly over the meatballs and cover with the lid to allow the cheese to melt.
  8. Serve: Spoon the meatballs onto plates, making sure to include plenty of the rich onion broth and melted cheese. Serve hot for a comforting meal.

Notes

  • Use lean ground beef to reduce fat content if preferred.
  • Substitute gluten-free breadcrumbs to make this dish gluten-free.
  • Caramelizing the onions slowly is key for authentic French onion flavor.
  • For a richer taste, butter can replace olive oil when sautéing onions.
  • Gruyere can be swapped with Swiss or mozzarella for different cheese textures and flavors.
  • Serve with crusty bread or over mashed potatoes for the perfect pairing.
  • Leftovers can be refrigerated for up to 3 days or frozen for up to 1 month.
