Ingredients Notes

The secret to a great Roast Beef Reuben lies in its carefully chosen ingredients. Each component brings something special to the table, ensuring every bite is packed with flavor.

Start with rye bread, which adds a nutty, slightly tangy foundation to the sandwich. The seeds in rye bread also provide a subtle crunch that complements the other textures.

For the protein, opt for high-quality roast beef. Whether it’s freshly sliced from the deli or leftover from a previous meal, tender, flavorful roast beef is the star of this dish.

The sauerkraut is essential for adding tanginess and a bit of crunch. Be sure to drain it well and even pat it dry to prevent your sandwich from becoming soggy.

Swiss cheese brings creaminess and just the right amount of nuttiness. It melts beautifully, creating that gooey, irresistible layer that holds everything together.

Finally, Thousand Island dressing ties the whole sandwich together. Its creamy, sweet, and tangy notes perfectly complement the richness of the roast beef and cheese.

You’ll also need a little butter or oil for toasting the bread. A large skillet or griddle is ideal for achieving that golden, crispy exterior.

How To Make This Roast Beef Reuben

Making a Roast Beef Reuben is as straightforward as it is satisfying. Let’s break it down step by step.

Start by preheating a skillet over medium heat. While the pan heats, spread a thin layer of butter on one side of each slice of rye bread. This will help create a crispy, golden crust.

Lay the bread butter-side down on the skillet. On one slice, layer Swiss cheese, followed by a generous portion of roast beef and sauerkraut. Spread Thousand Island dressing on the other slice.

Carefully place the sauerkraut-topped slice over the one with dressing, creating a sandwich. Press gently with a spatula to help the layers meld together.

Cook the sandwich for 3-4 minutes on each side, or until the bread is golden brown and the cheese is melted. Keep an eye on the heat to avoid burning the bread.

Once done, remove the sandwich from the skillet and let it cool slightly before slicing in half. This step ensures the layers stay intact when you serve it.

Storage Options

While this sandwich is best enjoyed fresh, you can prepare components ahead of time to save effort later.

Store leftover roast beef in an airtight container in the refrigerator for up to three days. The same goes for sauerkraut, which should be drained and kept in a separate container to maintain its texture.

To reheat the sandwich, use a skillet or toaster oven to restore its crispiness. Avoid microwaving, as this can make the bread soggy and the cheese rubbery.

Variations and Substitutions

The Roast Beef Reuben is a versatile recipe that can be tailored to your tastes and dietary needs.

For a leaner option, swap out roast beef for turkey or even grilled chicken. These proteins work well with the other classic Reuben flavors.

Not a fan of sauerkraut? Try using coleslaw instead. Its crunchy texture and tangy dressing offer a similar contrast to the rich cheese and meat.

If you’re avoiding rye bread, substitute with sourdough or another hearty loaf. Just ensure the bread is sturdy enough to hold up during toasting.

Vegetarian? You can replace the roast beef with a generous layer of grilled vegetables, like zucchini and bell peppers, for a fresh twist.

Feel free to experiment with spreads, too. Instead of Thousand Island dressing, try spicy mustard or even a garlic aioli for a bold flavor profile.

The Roast Beef Reuben is your canvas—mix and match ingredients to create a version that’s uniquely yours. Enjoy exploring all the possibilities this sandwich has to offer!
