Big New York Deli Reuben are Back on the Menu

Do you miss the piled high New York style deli sandwiches since going keto? Well this is the recipe for you!!! I’ve got a legit Rueben sandwich made with a rye Swiss chaffle recipe. You don’t have to miss out on your deli delights anymore!!

As a young man I chased a girl to New York and spent a lot of time up there. One of my favorite places to visit was Katz deli. The sliced corn beef piled high on rye bread. As well as the surgeon like knife skills of the cutters behind the counter. I was torn between the Reuben or the pastrami on rye with tons of spicy mustard. Both sandwiches are iconic and definitely a big part of New York food culture. I may have lost the girl but that doesn’t mean I have to lose the sandwich too.

The "Chaffle" Craze is Sweeping the Nation!!

I know I’m not the first person to make a chaffle and judging by the craze sweeping the keto community I won’t be the last. That being said I wanted to put my twist on one of my favorite sandwiches in the land...the New York Style Reuben. A classic Reuben has sauerkraut, Russian dressing, Swiss cheese and copious amounts of corned beef piled high on rye bread. If you’re not big on sauerkraut you can substitute coleslaw. That substitute is known as a Rachel, the sister sandwich to the Reuben.

If you don't have a Waffle Iron here is a cheap mini version that will make 4 chaffles per batch. Dash Mini Waffle Maker

Pastrami vs. Corned Beef

This might seem blasphemous but I substituted pastrami instead of corn beef. I tend to prefer pastrami because of the peppery crust and smokier flavor. I figured if I was making a ketofied Reuben on a cheese waffle I could take a few liberties.

A Very Reuben Twist on the Chaffle

When it comes to the chaffle I made a few adjustments to make this recipe closer to the classic flavors of an authentic Rueben. I added caraway seeds to give the chaffle that rye flavor profile. I also substituted Swiss cheese instead of mozzarella or cheddar to add subtle nutty flavor.

Easy Keto Friendly Russian Dressing

I kept the Russian dressing very simple using an avocado oil mayo and AlternaSweets Classic Ketchup. AlternaSweets Ketchup is by far my favorite because it’s sweetened with stevia and erythritol instead of aspartame or sucralose. The flavor of the ketchup tastes just like the real thing and is great for adding to lots of other recipes. They also make a spicy ketchup and sweet & smoky bbq sauce that are both outstanding!!
