Make this tender, juicy Crockpot French Onion Meatloaf. This slow cooker recipe uses simple ingredients to create a comforting, flavorful dinner with minimal effort, topped with gooey Swiss cheese.

Ingredients

Scale
  • 2 pounds ground beef
  • 1 packet French onion soup mix
  • 1 cup breadcrumbs
  • 1/2 cup milk
  • 2 eggs, beaten
  • 1/4 cup ketchup
  • 1 tablespoon Worcestershire sauce
  • 1 cup caramelized onions
  • 1 cup Swiss cheese, sliced
  • Fresh thyme, for garnish

Instructions

  1. In a large bowl, combine the ground beef, French onion soup mix, breadcrumbs, milk, beaten eggs, ketchup, and Worcestershire sauce. Mix these ingredients until they are just combined. Do not overwork the meat mixture.
  2. Shape the meat mixture into a loaf shape. Place the meatloaf carefully into your crockpot.
  3. Cover the crockpot. Cook on low for 6 to 7 hours or on high for 3 to 4 hours. The internal temperature must reach 160°F (71°C).
  4. During the final 30 minutes of cooking time, spread the caramelized onions over the top of the meatloaf. Place the Swiss cheese slices evenly over the onions.
  5. Cover and continue cooking until the cheese melts and becomes bubbly.
  6. Remove the meatloaf from the crockpot using a wide spatula. Slice the meatloaf and garnish with fresh thyme before serving. Serve this hearty slow cooker meal with your favorite sides.

Notes

  • For the best flavor, use store-bought caramelized onions or prepare them ahead of time.
  • If you prefer a firmer glaze, you can briefly place the meatloaf under the broiler after removing it from the crockpot to brown the cheese.
  • This recipe works well as a savory beef casserole alternative when served over mashed potatoes.
