Why I made this Keto Reuben Sandwich

My very favorite sandwich pre-keto was the Reuben. I loved the buttery toasted rye bread combined with the salty corned beef and tangy sauerkraut. Buttery swiss cheese and a sweet and tangy Thousand Island Dressing were just delicious on this corned beef sandwich!

I knew I had to have a low carb version that I would be able to enjoy when I had the craving for a Reuben. So, in preparation for this sandwich, I went ahead and created a Keto Rye Bagel and a sugar-free Thousand Island Dressing recipe. This was a double win for me because the dressing also happens to be Grumpy’s favorite dressing of all time!

What is a Keto Reuben Open-Faced Sandwich?

The Keto Reuben is a low carb version of an American Grilled Sandwich made up of corned beef, sauerkraut, cheese, and Russian Dressing. I used a Keto Rye Bagel instead of bread and used a sugar-free Thousand Island Dressing to sauce it up!!

What kind of meat do you eat on a Keto Reuben Sandwich?

The traditional meat is corned beef. You can buy it at the deli, or you can used leftover corned beef from a roast. However, I have used turkey or pastrami. When you use pastrami, you do have what is called the “Rachael”. I feel you can add any type of protein that is your preference.

Can I substitute Coleslaw for Sauerkraut?

You can, but that again, turns this Keto Reuben into a Rachael sandwich, especially if you use pastrami! I personally love the tang of sauerkraut in this sandwich!

What kind of dressing do you use in a Keto Reuben Sandwich?

The traditional is Russian. We prefer Thousand Island Dressing. The flavors however, are very similar where the Russian may have a sweeter side (and no pickles).

What do you eat with a Keto Reuben Sandwich?

When your eating a Keto Reuben, I recommend eating a low carb dill pickle or Pickled Green Beans! If you have a hankering for a chip on the side, try this Keto Zucchini Chips with Everything but the Bagel Seasoning!

When I am making lunch for just myself or even for just Grumpy and me, I hate to heat my oven up for just a small sandwich. That is why I LOVE my Hamilton Beach Toaster Oven. Not only does it quickly heat up, but it has my keto Reubens hot and toasty in no time flat!
