Ingredients

Scale

Caramelized Onions

  • 2 large sweet onions, thinly sliced
  • 2 tbsp salted butter
  • 1 tbsp olive oil
  • 1 tsp sea salt
  • ½ tsp coarse black pepper
  • 1 tsp granulated sugar
  • 1 tbsp cooking sherry (optional)

Meatloaf

  • 1 ½ lbs ground beef (80/20)
  • ½ cup Italian-style breadcrumbs
  • ¼ cup whole milk
  • 1 large egg
  • 1 packet (1 oz) French onion soup mix
  • 1 tbsp Worcestershire sauce
  • Half of the caramelized onions (reserve the rest for topping)

Topping

  • Remaining half of caramelized onions
  • 6–8 slices Swiss, Gruyère, or provolone cheese
  • Fresh thyme sprigs (for garnish)

Instructions

  1. Caramelize the Onions: In a skillet over medium heat, melt the butter and olive oil together. Add the thinly sliced sweet onions, sea salt, coarse black pepper, and granulated sugar. Stir occasionally and cook for 30-40 minutes until the onions turn a deep golden brown and are beautifully caramelized. Deglaze the pan with the cooking sherry if using, then remove from heat and set aside.
  2. Prepare the Meatloaf Mixture: In a large bowl, combine the ground beef, Italian-style breadcrumbs, whole milk, large egg, French onion soup mix, Worcestershire sauce, and half of the caramelized onions you prepared earlier. Mix gently until all ingredients are well incorporated, being careful not to overwork the meat.
  3. Shape and Place in Crockpot: Form the meat mixture into a loaf shape and place it on parchment paper or foil inside your crockpot base, ensuring even thickness for uniform cooking.
  4. Slow Cook the Meatloaf: Cover the crockpot and cook on LOW for 5-6 hours or on HIGH for 3-4 hours. The meatloaf is done when an internal temperature of 160°F (71°C) is reached. Once cooked, carefully drain any excess liquid from the crockpot before proceeding to the topping step.
  5. Add the Cheese and Onion Topping: Spread the remaining caramelized onions evenly over the top of the meatloaf. Next, layer 6-8 slices of Swiss, Gruyère, or provolone cheese on top. Cover the crockpot again and allow the cheese to melt for 5-10 minutes.
  6. Optional Broiling for Golden Finish: For an extra golden and bubbly cheese topping, transfer the meatloaf to an oven-safe dish and broil in the oven for 2-3 minutes, watching carefully to avoid burning.
  7. Garnish and Serve: Finally, garnish the meatloaf with fresh thyme sprigs for an aromatic finish. Serve warm and enjoy this savory, comforting dish.

Notes

  • Cooking sherry is optional but adds a nice depth of flavor to the caramelized onions.
  • Use a meat thermometer to ensure the meatloaf reaches a safe internal temperature of 160°F (71°C).
  • If preferred, you can substitute ground beef with a mix of beef and pork for added richness.
  • For a gluten-free version, use gluten-free breadcrumbs or crushed gluten-free crackers.
  • Leftover meatloaf slices reheat well in a microwave or oven.
  • The broiling step is optional but highly recommended for a melted, browned cheese topping.
