  • 1 pound Deli Corned Beef, chopped
  • 1 cup Sauerkraut, well-drained
  • 2 cups Shredded Swiss Cheese or a blend of Swiss and Mozzarella
  • 1 cup Full-Fat Mayonnaise

Preparation Steps

  • Begin by preheating your oven to 350°F (175°C) and greasing a 9x13-inch baking dish.
  • In a large mixing bowl, combine the mayonnaise, sugar-free ketchup, chopped onion, and apple cider vinegar. Blend until smooth.
  • Next, add in the chopped corned beef, drained sauerkraut, dill pickle relish, sugar substitute, and smoked paprika, mixing everything thoroughly until well-coated.
  • Transfer the mixture into the prepared baking dish and layer the shredded Swiss cheese evenly on top.
  • Bake in the preheated oven for 25 minutes, or until the cheese is melted and the casserole is golden brown. Allow it to rest for 5 minutes before serving.
