Ingredients

Scale
  • 1 pound sliced corned beef, chopped
  • 1 (16 ounce) can sauerkraut, drained well and squeezed dry
  • 1 tablespoon butter
  • 1/2 cup chopped onion
  • 1 teaspoon caraway seeds
  • 1/2 cup Thousand Island dressing
  • 1/2 cup mayonnaise
  • 1 tablespoon Dijon mustard
  • 1/2 teaspoon black pepper
  • 1 (14.5 ounce) package rye bread, cut into 1-inch cubes
  • 12 ounces Swiss cheese, shredded

Instructions

  1. Preheat your oven to 375 degrees Fahrenheit. Lightly grease a 9×13 inch baking dish.
  2. In a medium skillet over medium heat, melt the butter. Add the chopped onion and cook until softened, about 5 minutes. Stir in the caraway seeds and cook for 1 minute more until fragrant. Remove from heat.
  3. In a large bowl, combine the chopped corned beef and the drained sauerkraut. Add the cooked onion mixture.
  4. In a separate small bowl, whisk together the Thousand Island dressing, mayonnaise, Dijon mustard, and black pepper until smooth.
  5. Pour the dressing mixture over the corned beef and sauerkraut mixture. Toss gently until everything is evenly coated.
  6. Add the cubed rye bread to the large bowl and gently fold it into the meat and sauerkraut mixture until the bread pieces are coated.
  7. Spread half of the mixture evenly into the prepared baking dish. Sprinkle half of the shredded Swiss cheese over this layer.
  8. Top with the remaining corned beef mixture. Finish by sprinkling the remaining Swiss cheese over the top layer.
  9. Bake for 25 to 30 minutes, or until the casserole is heated through and the cheese on top is bubbly and lightly golden brown.
  10. Let the Homemade Reuben Bake rest for 5 minutes before cutting and serving.

Notes

  • For an extra savory touch, use marbled rye bread.
  • If you prefer a tangier flavor, use a dill pickle relish in place of some of the sauerkraut.
  • This dish makes excellent leftovers for lunch the next day.
