What Makes Reuben Casserole So Great?

  • Fast. Enjoy this tasty casserole in under 30 minutes.
  • Easy. Make the dressing, layer the ingredients, and bake.
  • Low Carb. Only 6 net carbs per serving.
  • Gluten-free. No need to worry about finding allergy-friendly bread for a sandwich when you can skip the bread completely.

The thing about Reubens, in all their drippy, messy, tasty goodness though? Is that classic rye bread. Terribly tasty, entirely not keto or low carb.

Ever since I started eating low carb though, one of the things I’ve learned is that it really is all about the insides of the sandwich anyway. That’s where ALL the flavor is at.

So making a baked Reuben casserole is fairly easy, really. This is how you can take all the flavor of a Reuben sandwich, but make it low carb.

How Did The Reuben Get Its Name?

As I was looking up the origins of a Reuben sandwich, I was surprised to discover that there was once an actual Reuben’s Deli in New York. Mr. Arthur Reuben used to name sandwiches for the famous celebrities that ate at this restaurant.

So I guess it’s only fitting that we now have a sandwich named for Reuben himself.

Do You Use Pastrami or Corned Beef in a Reuben?

If you’re anything like me, you have no idea about the difference between Pastrami and Corned beef. All I know is, they are both beef, they’re both cured, and they’re both delicious.

I also know that using both together in a Reuben makes an already delicious dish even better.

If you really must know, the biggest difference is that both cuts are brisket but Pastrami is a little fattier cut than corned beef. They’re both brined. But corned beef is boiled, and pastrami is smoked.

I suggest using half and half of each as I did in this Reuben Casserole recipe.

Tips and Tricks for Making a Keto Reuben Casserole

  • Use a 9-inch cake pan or an 8 x 8 baking pan to make this casserole.
  • Use a combination of thinly sliced pastrami and corned beef.
  • Drain the sauerkraut as well as you can. Despite this, you will have some sauce in the bottom of the pan once it’s baked. I drizzled most of this over the casserole.
  • If you don’t care about making this low carb, you can always layer the bottom with pieces of rye bread. Top with rye bread as well, and bake as directed. In this case, the bread will soak up all the lovely dressing. But of course, for low carb, either skip the bread or try it with Sola bread which is currently my favorite low carb bread.
  • Use Swiss cheese or any other kind of melting cheese for the top.
  • The caraway seeds add a lovely crunch to this dish. You can also buy sauerkraut with caraway seeds and skip a step.

How To Make a Baked Reuben Casserole Recipe

  1. Mix mayonnaise, low-sugar ketchup, hot sauce, and onions together to make your own Thousand Island Dressing.

4. Spread the dressing on top of the sauerkraut.

5. Spread a few more slices of pastrami and corned beef. You are doing this to keep the cheese and the dressing from making a melty mess. Although, it WOULD be a very tasty mess!

6. Use some kind of good melting cheese, like Swiss cheese.

7. Bake the casserole and then slice. Notice, you will have a lot of sauce at the bottom. If you are not doing low carb, you can use bread at the bottom. If you are low carb but still want bread, I’d use this Sola bread at the bottom.

8. If you can let the casserole rest for 10-15 minutes, a lot of that sauce gets absorbed back in. Otherwise, just drizzle it on your casserole and enjoy.
