A comforting casserole that transforms classic Reuben sandwich flavors into a crispy, cheesy baked dish perfect for busy nights.

Ingredients

Scale
  • 12 ounces corned beef, chopped or shredded
  • 68 slices rye bread, cubed (day-old preferred)
  • 1 cup sauerkraut, well-drained
  • 1 ½ cups Swiss cheese, shredded
  • 1 cup cheddar cheese, shredded
  • ½ cup Thousand Island dressing
  • 3 tablespoons butter, melted
  • 1 tablespoon yellow mustard
  • ½ small onion, finely chopped (optional)
  • Freshly ground black pepper, to taste
  • ½ teaspoon caraway seeds (optional)

Instructions

  1. Preheat your oven to 375°F (190°C). Grease an 8×8-inch (20×20 cm) casserole dish with butter or cooking spray.
  2. Toss the rye bread cubes with 2 tablespoons of melted butter and black pepper to ensure they crisp up nicely.
  3. In a medium bowl, combine the drained sauerkraut, chopped corned beef, chopped onion (if using), mustard, and Thousand Island dressing. Stir gently until evenly coated.
  4. Spread half the bread cubes evenly on the bottom of the casserole dish.
  5. Add the corned beef and sauerkraut mixture in an even layer over the bread.
  6. Top with the remaining bread cubes.
  7. Sprinkle shredded Swiss and cheddar cheeses evenly over the top bread layer.
  8. Drizzle the remaining 1 tablespoon of melted butter across the cheese to help it brown.
  9. Bake for 30-35 minutes until the top is golden and crispy and the filling is bubbly.
  10. Let the casserole rest for 5-10 minutes before serving to allow layers to settle.

Notes

Use day-old bread to prevent sogginess. Drain sauerkraut thoroughly to avoid excess moisture. If top browns too quickly, tent with foil after 20 minutes. Freshly shredded cheese improves crust browning. For gluten-free, use gluten-free bread; for lactose-free, substitute dairy-free cheeses.
