Ingredients

Scale
  • 1 pound cooked corned beef, chopped
  • 1 (16 ounce) can sauerkraut, drained well
  • 1 cup Thousand Island dressing
  • 1 tablespoon Dijon mustard
  • 1 teaspoon Worcestershire sauce
  • 1 pound Swiss cheese, shredded
  • 1 (14.7 ounce) package rye bread or pumpernickel bread, cut into 1-inch cubes
  • 4 tablespoons unsalted butter, melted

Instructions

  1. Preheat your oven to 375 degrees Fahrenheit. Lightly grease a 9×13 inch baking dish.
  2. In a large bowl, combine the chopped corned beef and drained sauerkraut.
  3. In a separate small bowl, whisk together the Thousand Island dressing, Dijon mustard, and Worcestershire sauce to create the dressing mixture.
  4. Add the dressing mixture to the corned beef and sauerkraut. Toss gently to coat everything evenly.
  5. Add half of the shredded Swiss cheese and half of the rye bread cubes to the meat mixture. Stir until just combined.
  6. Transfer the mixture to your prepared baking dish and spread it into an even layer.
  7. Top the mixture evenly with the remaining rye bread cubes. Drizzle the melted butter over the bread cubes.
  8. Bake for 20 minutes.
  9. Remove the dish from the oven and sprinkle the remaining Swiss cheese over the top.
  10. Return the casserole to the oven and bake for another 5 to 10 minutes, or until the cheese is melted and bubbly and the top is lightly golden brown.
  11. Let the Homemade Reuben Bake rest for 5 minutes before you serve it.

Notes

  • Drain the sauerkraut thoroughly; excess liquid will make your bake watery. Press it firmly between paper towels if needed.
  • You can substitute deli-sliced corned beef for chopped, but chopping makes for better layering in the casserole.
  • For an extra savory flavor, use marbled rye bread.
