The History Behind the Reuben

The Reuben sandwich is one of America’s most beloved deli classics. Traditionally made with corned beef, Swiss cheese, sauerkraut, and Russian or Thousand Island dressing on rye bread, it became popular in the early 20th century.

Several stories claim credit for its creation, with one of the most famous linking it to Reuben Kulakofsky, a grocer from Omaha, Nebraska. Regardless of its exact origins, the Reuben quickly became a staple in delicatessens across North America.

This stuffed mushroom version preserves the iconic flavors while transforming the sandwich into a nutritious, low-carb dish.
