Wendy’s Tips

Shred your Swiss cheese fresh, if possible, for maximum meltiness. Pre-shredded cheese sometimes contains anti-caking agents.
Toast your rye bread cubes with a drizzle of butter before layering them on for an extra crunch factor.
Make it low-carb! Skip the rye bread and add more layers of corned beef and Swiss cheese for a keto-friendly meal.

FAQs

What makes a Reuben casserole different from a Reuben sandwich?

A Reuben casserole has all the same amazing flavors as a Reuben sandwich but is baked in a single dish! Instead of being layered between bread, the ingredients are combined and baked, making it perfect for serving a crowd.

Do I need to use rye bread?

Using rye bread gives this casserole its signature Reuben flavor thanks to the caraway seeds, but you can swap it for any bread you prefer or leave it out completely for a low-carb option.
