Make a flavorful, juicy meatloaf with minimal effort using your slow cooker. This recipe uses French onion soup mix for deep flavor and tops the loaf with melted Swiss cheese.

Ingredients

Scale
  • 2 lbs ground beef (80/20 recommended)
  • 1 large egg
  • 1 cup breadcrumbs (plain or panko)
  • 1/2 cup milk
  • 1 packet (1.25 oz) dry onion soup mix
  • 1/4 cup finely chopped onion (optional, for extra flavor)
  • 1 teaspoon Worcestershire sauce
  • 1/2 teaspoon black pepper
  • 4 slices Swiss cheese
  • 1/2 cup beef broth (for the bottom of the slow cooker)

Instructions

  1. In a large bowl, gently mix the ground beef, egg, breadcrumbs, milk, dry onion soup mix, optional chopped onion, Worcestershire sauce, and pepper. Do not overmix.
  2. Shape the mixture into a loaf shape that fits your slow cooker insert.
  3. Pour the beef broth into the bottom of the slow cooker insert around the meatloaf. This keeps the bottom moist.
  4. Cover the slow cooker and cook on LOW for 5 to 6 hours or on HIGH for 3 to 3.5 hours, until the internal temperature reaches 160°F.
  5. About 15 minutes before cooking time ends, remove the lid and place the Swiss cheese slices evenly over the top of the meatloaf. Replace the lid until the cheese melts.
  6. Carefully remove the meatloaf from the slow cooker using two spatulas. Let it rest for 10 minutes before slicing and serving.

Notes

  • For a richer flavor, you can substitute 1 cup of caramelized onions for the dry onion soup mix, but this requires pre-cooking the onions.
  • If you prefer a firmer loaf, line the slow cooker insert with parchment paper, leaving an overhang to lift the meatloaf out easily after cooking.
  • Drain off any excess liquid from the slow cooker before adding the cheese if the broth has reduced significantly.
