Ingredients

Scale
  • 1 pound cooked corned beef, shredded or chopped
  • 1 (16 ounce) can sauerkraut, drained well and squeezed dry
  • 1 cup Thousand Island dressing
  • 1 tablespoon Dijon mustard
  • 1 teaspoon Worcestershire sauce
  • 1/2 teaspoon garlic powder
  • 1/4 teaspoon black pepper
  • 6 cups rye bread, cut into 1-inch cubes
  • 2 cups shredded Swiss cheese, divided
  • 1/2 cup (1 stick) 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 shredded corned beef and the dried sauerkraut.
  3. In a separate small bowl, whisk together the Thousand Island dressing, Dijon mustard, Worcestershire sauce, garlic powder, and black pepper. Pour this dressing mixture over the corned beef and sauerkraut. Toss gently to coat everything evenly.
  4. Add the cubed rye bread and 1 cup of the Swiss cheese to the meat and sauerkraut mixture. Gently fold the ingredients together until the bread is lightly coated.
  5. Pour the entire mixture into the prepared baking dish, spreading it into an even layer.
  6. Drizzle the melted butter evenly over the top of the casserole mixture.
  7. Sprinkle the remaining 1 cup of Swiss cheese over the top layer.
  8. Bake for 25 to 30 minutes, or until the cheese is melted, bubbly, and the edges are lightly browned.
  9. Let the Homemade Reuben Bake rest for 5 minutes before you serve it.

Notes

  • Squeeze the sauerkraut very dry; excess moisture makes the bake soggy.
  • For a crispier top, you can briefly place the dish under the broiler for the last minute, watching closely to prevent burning.
  • This recipe makes a great Weeknight Reuben Recipe alternative to sandwiches.
