The Reuben ‘sandwich’ is a North American grilled sandwich composed of corned beef, Swiss cheese, sauerkraut, and Thousand Island dressing, or Russian dressing, grilled between slices of rye bread.
The Reuben actually has a couple of origin stories. It just depends on who tells it. Of course, all the ingredients have roots in places besides North America. You have the cheese which is Swiss. The rye bread comes from eastern Europe. Corned beef is an ancient way of preserving meat in cultures all over the world. Sauerkraut has a very ancient history and most likely originated with the Mongols or in ancient China.
The combined flavors of a Reuben sandwich are so amazing that its inspired many recipe ideas and ways to incorporate the flavors into other foods.
Reuben Stuffed Shells pack all that flavor into a jumbo pasta shell and the homemade croutons make sure that you won’t miss out on the rye bread that Reubens are known for.
