Make this comforting twist on the classic Reuben sandwich as a simple, hearty casserole. Layers of corned beef, tangy sauerkraut, Swiss cheese, and Thousand Island dressing bake between slices of rye bread for a cheesy, satisfying weeknight dinner.

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
  • 1/2 teaspoon black pepper
  • 1/2 cup butter, melted
  • 1 (16 ounce) loaf rye bread, cut into 1-inch cubes
  • 8 ounces Swiss cheese, shredded

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, drained sauerkraut, Thousand Island dressing, Dijon mustard, Worcestershire sauce, and black pepper. Mix gently until all ingredients are evenly coated.
  3. Place half of the rye bread cubes in a single layer in the bottom of the prepared baking dish. Brush the bread lightly with half of the melted butter.
  4. Spread the corned beef and sauerkraut mixture evenly over the layer of bread.
  5. Sprinkle half of the shredded Swiss cheese over the meat mixture.
  6. Top with the remaining rye bread cubes. Brush the top layer of bread with the remaining melted butter.
  7. Bake for 20 minutes.
  8. Remove the dish from the oven and sprinkle the remaining Swiss cheese over the top.
  9. Return the casserole to the oven and bake for another 5 to 10 minutes, or until the cheese is melted, bubbly, and lightly golden brown.
  10. Let the Homemade Reuben Bake rest for 5 minutes before slicing and serving.

Notes

  • For a richer flavor, use pastrami instead of corned beef.
  • If you prefer a less tangy result, rinse the sauerkraut lightly before draining.
  • This casserole works well for potlucks; cover and refrigerate assembled, unbaked casserole for up to 24 hours. Add 10-15 minutes to the initial baking time if baking cold.
