Slow Cooker Meatloaf

This meatloaf is filled with cheese, caramelized onions, ketchup, yellow mustard and topped with a sweet ketchup glaze. A true homemade comfort food made simple thanks to your slow cooker!


  • 40 oz lean ground beef or chopped steak
  • 1 cup caramelized onions
  • 1 green pepper, raw
  • 3 eggs
  • 1 cup breadcrumbs
  • 1 tbsp kosher salt
  • 1/2 tbsp black pepper, ground
  • 1/2 cup yellow mustard
  • 1 cup ketchup
  • 8 oz Crystal Farms Shredded Swiss Cheese
  • 2 cups mushrooms, sliced


  • In a large mixing bowl, combine ground beef, caramelized onions, peppers, eggs, breadcrumbs, salt and pepper. Mix well.
  • In a separate bowl, combine mustard and ketchup. Add half of mixture to the beef mix and reserve other half.
  • Add half of the beef mixture to the slow cooker, leaving a gap in the middle like a boat. Fill this gap with shredded Swiss cheese, and top with the remaining beef mixture.
  • Add mushrooms around the sides and over the top of the meatloaf in the slow cooker.
  • Cook meatloaf on high for 2 ½-3 hours until internal temperature reaches 165° F.
  • Turn to low and top with remaining ketchup mix. Let the meatloaf cook for another hour to slightly caramelize the glaze.
