This Keto Reuben is a delicious open-faced sandwich, bringing bold deli flavors to your table for a quick and easy low carb lunch. Slices of savory corned beef are layered with a tangy dressing, sauerkraut, and Swiss cheese then finished under the broiler until bubbly. It's a satisfying way to enjoy a classic favorite while keeping your carb count low.
I love making this Keto Reuben when I have leftover corned beef from dinner, as it comes together in just minutes. By using a toasted keto rye bagel you get that familiar rye flavor and texture that makes a Reuben so iconic. It's the perfect solution for staying on track with your keto lifestyle without sacrificing the comfort food you love.
