Calling all Reuben lovers. Think of Reuben Casserole as making a whole load of Reuben sandwiches in a few simple, quick steps. Rye bread, thin sliced corned beef, homemade thousand island dressing, sauerkraut, and Swiss Cheese are combined to make a mouthwatering taste experience. I love to serve this for a quick weeknight dinner or weekend lunch. For a complete meal, serve with Marinated Cucumbers and Red Onions or Beer Battered Onion Rings with Dipping Sauce.

St. Patrick’s Day is right around the corner, and I am sure this is a pretty good chance that you are making corned beef and cabbage. Are you planning on making enough for leftovers? This casserole is perfect for your leftover corned beef. No worries if you don’t have any leftovers. You can always go to your local grocery store and pick up some good quality deli corned beef.

How do you make Reuben Casserole?
Start by layering the bottom of a baking dish with rye or pumpernickel bread cubes. Next, layer the corned beef, thousand island dressing (either homemade or bottled), well-drained sauerkraut, and shredded Swiss Cheese.
Next, bake uncovered in the oven for about 20-25 minutes. If the casserole browns too fast, then cover it with a loose aluminum foil tent. Allow it to cool for a couple of minutes covered before cutting.

Helpful tips for making Reuben Casserole
- There is no need to toast the bread. Pumpernickel and rye are good sturdy choices for this Reuben casserole, and you want to keep a little bit of softness in the bite.
- Chop the corned beef into bite-size pieces as it makes it easier to cut into pieces.
- Drain the sauerkraut well. You don’t want any excess moisture making your Reuben casserole soggy.
- Use either homemade thousand island dressing (so yummy) or your favorite bottle dressing.
- Bake just until the cheese is melted and the casserole is heated through.

What a clever and interesting idea! I have never thought of a reuben as more than a sandwich, and as you cannot get proper rye bread in England, this sounds fun.

Of course you can get proper Rye Bread in New England – go to a Swedish bakery!
