Allow me to introduce you to one of my all-time favorite creations. I am passionate about Reubens, and this easy to make Keto Reuben Sandwich is my idea of perfection. When you combine a crispy buttery chaffle, melted cheese, corned beef, sauerkraut, and a delicious sauce, you have got mealtime bliss.
This Keto Reuben Sandwich is Cheesy, Buttery Goodness!
I am not quite sure when my love affair with Reuben Sandwiches began.
For years, I steered clear of them because my mom ingrained in me that sauerkraut was "gross." (Turns out I love it.)
The first time I ordered one out, I was at a cute lunch spot with a limited menu. I ordered it without sauerkraut - to be safe!
Over time, I got more adventurous with food, and the first time I ordered a Reuben as it comes, I was madly in love. I couldn't believe that I'd spent 20+ years avoiding sauerkraut.
We used to go to a little restaurant in Asheville called Chestnut that had the BEST Reuben ever.

It was full of cheesy, buttery goodness.
I ordered it every time we went.
Since going low carb, sandwiches are among the things that I miss the most. That is, I missed them until I started making chaffles.
If you haven't jumped on the chaffle bandwagon, what are you waiting for? They have been a game-changer for me in my ability to stick to a keto diet.
I am in love with this Keto Reuben Sandwich so much! I would have it on the menu every week if I could.
A couple of things to note about this recipe.
This is a big sandwich. I have never been able to eat a whole one. I save it and reheat the uneaten half in my air fryer for another meal.
Also, if you don't have a waffle iron and don't want to get one, any bread will do here. Just make sure it is sturdy enough to hold up to all the fillings. Happy eating!
Tips & Tricks
- I recommend using a skewer or toothpicks to secure the sandwich when you are cooking them.
- Alternatively, you can butter the outside of the chaffles and cook the sandwiches in the air fryer for about 5 minutes at 400 degrees.
How to Make a Keto Reuben Sandwich
1 First, make your chaffle by combining 1 egg, ½ cup mozzarella, 1 tablespoon almond flour, and 1 teaspoon ground caraway seeds in a bowl. (Skip this step if you are using keto-friendly bread.)
2 Stir to combine. Divide the mixture in two and spread half on a dash mini waffle maker. Cook for 5 to 7 minutes. Repeat with the other half.
3 Meanwhile, while the chaffles cook, combine mayonnaise, diced pickles, and sugar-free ketchup in a small bowl. Stir to combine.
4 Spread the sauce on one chaffle and place half of the meat on another.
5 Top the corned beef with cheese.
6 Finally, add the sauerkraut.
7 Melt butter over medium heat in a large skillet. Cook the sandwiches for 4 minutes. Flip and cook for another 4 minutes, or until the cheese melts.
Frequently Asked Questions
Sauerkraut isn’t my thing. What can I use?
I would suggest using a good keto-friendly coleslaw. Only then, technically your sandwich will not be a Reuben. It's now a Rachel!

What kind of ketchup can I use on keto?
I often make my own keto ketchup. When I don't have time for that, this is the brand I use.
What is the best waffle iron for making chaffle sandwiches?
You can use any waffle iron, but I can't recommend the dash mini enough! This super-affordable waffle iron is perfect for sandwiches because it makes thin round waffles that are just the right size.
