Ingredients

Scale
  • 1 pound cooked corned beef, chopped
  • 1 (16 ounce) can sauerkraut, drained well and squeezed dry
  • 1/2 cup Thousand Island dressing
  • 1 tablespoon Dijon mustard
  • 1 teaspoon Worcestershire sauce
  • 1/2 teaspoon garlic powder
  • 1 pound Swiss cheese, shredded
  • 1 (14 ounce) package rye bread, cubed (about 6 cups)
  • 2 large eggs
  • 1/2 cup milk
  • 1/4 cup melted butter

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 the well-drained sauerkraut.
  3. In a small bowl, whisk together the Thousand Island dressing, Dijon mustard, Worcestershire sauce, and garlic powder. Pour this dressing mixture over the corned beef and sauerkraut. Toss gently to coat everything evenly.
  4. Add half of the shredded Swiss cheese and half of the cubed rye bread to the meat mixture. Stir until just combined.
  5. Spread the mixture evenly into the prepared baking dish. Top with the remaining rye bread cubes.
  6. In a separate bowl, whisk together the eggs, milk, and melted butter. Pour this egg and milk mixture evenly over the top layer of bread cubes. Let it soak for 5 minutes.
  7. Sprinkle the remaining Swiss cheese over the top of the casserole.
  8. Bake for 30 to 35 minutes, or until the casserole is bubbly throughout and the cheese on top is melted and lightly golden brown.
  9. Let the Homemade Reuben Bake rest for 5 minutes before you cut and serve it.

Notes

  • For the best flavor, squeeze as much liquid as possible from the sauerkraut before mixing it into the casserole.
  • You can prepare this entire casserole, cover it, and refrigerate it up to 24 hours before baking. Add 10 minutes to the bake time if cooking directly from the refrigerator.
  • If you want extra tang, add 1 teaspoon of caraway seeds to the meat mixture.
