Ingredients

Scale

Meat Ingredients:

  • 1 pound ground beef
  • 1 package onion soup mix

Binding Ingredients:

  • 1/2 cup bread crumbs
  • 1 egg
  • 1 teaspoon garlic powder

Liquid and Flavor Ingredients:

  • 1 cup beef broth
  • 2 tablespoons Worcestershire sauce
  • Caramelized onions (about 1 large onion, caramelized)
  • Mozzarella or Swiss cheese, shredded (optional, about 1/2 cup)
  • Fresh parsley, chopped, for garnish (optional)

Instructions

  1. Combine Ingredients: In a large bowl, blend ground beef with bread crumbs, egg, onion soup mix, garlic powder, and Worcestershire sauce until thoroughly mixed. Shape the mixture carefully into uniform round meatballs.
  2. Sear Meatballs: Heat a skillet over medium-high heat and sear the meatballs, turning to brown all sides evenly. This process should take about 3-4 minutes per side, creating a golden-brown crust that seals in the juices.
  3. Prepare Crockpot Base: Spread a layer of caramelized onions evenly along the bottom of the crockpot to build a rich flavor base for the meatballs.
  4. Layer Meatballs: Gently arrange the seared meatballs over the caramelized onions, spacing them slightly to allow for even cooking.
  5. Add Broth: Pour the beef broth over the meatballs, ensuring they are partially submerged to keep them moist and help them absorb the savory onion broth flavors.
  6. Slow Cook: Cover the crockpot and cook on low for 5 to 6 hours. This slow cooking ensures the meatballs become tender and soak up the rich broth and onion flavors.
  7. Add Cheese: During the last 30 minutes of cooking, sprinkle shredded mozzarella or Swiss cheese over the meatballs to allow it to melt and form a golden, gooey topping.
  8. Serve: Once done, carefully transfer the meatballs to a serving platter, garnish with freshly chopped parsley, and serve immediately while hot and aromatic.

Notes

  • Swap breadcrumbs with gluten-free alternatives like almond flour or crushed pork rinds for a low-carb version.
  • Use lean ground beef or ground turkey to reduce overall fat content without compromising flavor.
  • Caramelize onions beforehand to deepen the rich, sweet flavor profile and enhance the French onion essence of the dish.
  • Add a splash of red wine or balsamic vinegar during cooking to elevate the meatballs’ complexity and create a more gourmet experience.
