Ingredients for Reuben Casserole

Corned Beef – This is the perfect way to enjoy leftover corned beef. If you don’t have leftovers, ask the deli to thickly slice corned beef for you.

Bread – Rye bread gives this casserole its classic sandwich flavor. Use pumpernickel or another hearty bread. Add a dash or two of caraway seeds for that classic rye bread flavor.

Sauerkraut – Sauerkraut adds a tangy flavor to this casserole. Be sure to drain the sauerkraut; otherwise, the casserole will become soggy.

Cheese – Swiss cheese is our favorite in this recipe, but you can use provolone, Monterey Jack, or any tangy cheese that’s extra gooey when it melts!
