A Reuben sandwich is a classic American sandwich made with corned beef, Swiss cheese, sauerkraut, and Thousand Island dressing, grilled on rye bread. It is believed to have originated in the early 1900s at Reuben’s Delicatessen in New York City. The sandwich is named after Reuben Kulakofsky, a Lithuanian-Jewish immigrant who owned the deli.
The Reuben sandwich is a popular menu item at delis and restaurants across the United States. It is also a popular choice for home cooks, as it is relatively easy to make. The sandwich is typically served with a side of potato salad or coleslaw.
