I personally love reuben sandwiches, so when I started following the keto diet, I knew I had to find a way to make one. I started by making my own keto recipe for homemade rye flavored bagel studded with caraway seeds and used my favorite recipe for Thousand Islands dressing as a sauce. The two main ingredients that bring all the carbs to a classic reuben sandwich.

❤️ Why you'll love this Keto Reuben

Satisfying and flavorful: while this recipe has only 5 net carbs per serving, it certainly is packed with the same delicious flavor of a classic reuben sandwich.

Keto-Friendly Ingredients: This open-faced Reuben is a keto take on the classic sandwich that combines the goodness of a keto rye bagel, thinly sliced corned beef, Swiss cheese, sauerkraut, and a homemade Thousand Islands dressing.

Repurposing leftovers: this is a great way to use any leftover corned beef from your St. Patrick's Day celebration!

Customizable: this is a recipe for two people, however it is easy to increase amounts to adjust for more people.

🥘 Ingredients

Keto rye bagel: this is a homemade bagel is made with caraway seeds and has the flavor of the rye bread in the original sandwich.

Corned beef: either make your own homemade corn beef (I love this Instant Pot Corned Beef recipe) or buy it from the deli counter in thin slices.

Sugar-free Thousand Island Dressing

Swiss cheese

Sauerkraut: read the labels on the ingredient list and be sure to pick a tangy sauerkraut that has no added sugars.

1. Pre-heat toaster oven on broil setting while assembling your sandwich
2. Slice keto rye bagel in half and cover each half with 1 tablespoon Thousand Island Dressing.
3. Place 2 ounces corned beef on each bagel half over top of the dressing.
4. Place 1 tablespoon (or more if you wish) sauerkraut on top of corned beef.
5. Lay 1 ounce slice of Swiss cheese on top of the sauerkraut.
6. Place open face sandwich in toaster oven and broil until swiss cheese layer is melted and bubbly.
