Keto Reuben Chaffle Sandwich Directions
-
Preheat
Preheat waffle maker to medium high heat.
-
Mix the chaffle batter
In a small bowl, whisk together egg, mozzarella cheese, almond flour, 1 tablespoon low-carb thousand island dressing, caraway seeds and baking powder.
-
Add to waffle maker
Pour the reuben chaffle mixture into the center of the waffle iron. Close the waffle maker and let cook for 5-7 minutes or until waffle is golden brown and crisp. If using a mini dash waffle maker, only pour half the batter onto the waffle iron. This recipe will make two mini chaffles.
-
Make a waffle
Remove chaffle from the waffle maker. Repeat with remaining batter if using a mini dash waffle maker.
-
Assemble sandwich
On a piece of parchment paper, lay down the corned beef and top with a slice of swiss cheese. Heat in the microwave for 20-30 seconds until cheese starts to melt. Remove from microwave. Spread remaining tablespoon of low-carb thousand island dressing on each chaffle, layer the heated corned beef and swiss cheese and top with sauerkraut and remaining chaffle.
If you miss a good Rueben sandwich on the keto diet with lots of sliced corned beef, melted swiss cheese and piled high with sauerkraut, I’ve got good news for you! You now enjoy the keto Rueben sandwich thanks to the Rueben chaffle bread.
This chaffle bread recipe adds a hint of rye bread flavor by adding some caraway seeds and a splash of thousand island dressing. If you cook it for a long time on your waffle will be crisp, just like a real rye bread Rueben sandwich.
Although you can use any waffle maker will work for making chaffles. 
Traditionally, sliced corned beef is used to make Rueben sandwiches, but many people like to pile on the pastrami instead. You can use either deli meat in this recipe. My favorite is corned beef.
Yes,
Surprisingly good for a low carb alternative. I used my mini waffle maker and the chaffles turned out crispy and held together nicely. The caraway seeds were a great touch too.
Your “PIN” buttons aren’t working. Recipe sounds delicious, but haven’t tried it yet. Will post a report when I do.
I’ll get that figured out! Thanks for letting me know
Just made these and they were very flavorful and satisfying! The only changes I made were grinding my caraway seeds and used 1/2 mozzarella and 1/2 grated swiss in the chaffle. Get a good jar of crispy sauerkraut.
Fantastic Recipes. We’ve been doing KETO since October and your videos and recipes are a regular part of our diets. We used this recipe as burger buns. We used Cheddar Cheese too.
This was so amazing!
