Ingredient Notes

The magic of the Roast Beef Reuben lies in its balance of bold flavors and textures. Here’s a closer look at what you’ll need to create the perfect sandwich:

Roast Beef: Tender, thinly sliced roast beef is the star of this sandwich. If you’re using leftovers, warm them slightly before assembling to bring out their flavor. Deli-sliced roast beef works wonderfully too for an easy option.
Rye Bread: Classic rye bread adds that unmistakable tangy, earthy flavor. Look for marbled rye for an eye-catching presentation, or substitute with sourdough for a milder taste.
Swiss Cheese: Melty, nutty Swiss cheese pairs beautifully with the roast beef and tangy sauerkraut. If Swiss isn’t your favorite, try provolone or Gruyère for a similar effect.
Sauerkraut: This tangy, fermented cabbage is essential for the signature Reuben flavor. Be sure to drain and squeeze out excess liquid so your sandwich doesn’t become soggy.
Thousand Island Dressing: Creamy, slightly sweet, and tangy, this dressing ties all the components together. Homemade or store-bought works equally well. For a spicier kick, swap this out for Russian dressing.

No special equipment is needed – just a skillet or griddle to grill your sandwich to perfection.

How To Make This Roast Beef Reuben

Making a Roast Beef Reuben is surprisingly simple, and the results are always impressive. Let me guide you through the process step by step:

Prepare the Ingredients
Start by gathering all your ingredients. Drain the sauerkraut and pat it dry with paper towels to avoid excess moisture. Slice your roast beef thinly if it isn’t already prepped, and have your Swiss cheese and rye bread ready to go.
Assemble the Sandwich
Lay out two slices of rye bread per sandwich. Spread a generous layer of Thousand Island dressing on each slice. On one slice, layer the roast beef, followed by a scoop of sauerkraut, and top with Swiss cheese. Place the second slice of bread on top, dressing side down.
Heat the Pan
Heat a skillet or griddle over medium heat. Add a pat of butter and let it melt, swirling to coat the surface.
Grill the Sandwich
Place your assembled sandwich in the skillet. Cook for 3-4 minutes on one side, pressing down gently with a spatula to encourage browning. Flip carefully and cook the other side until the bread is golden and the cheese is melted. Repeat with additional sandwiches.
Serve Immediately
Slice the sandwich in half diagonally for the ultimate presentation and enjoy it hot. Serve with pickles, chips, or a simple green salad for a complete meal.

The whole process takes about 15 minutes from start to finish, making this an ideal choice for busy days or quick weeknight dinners.

Storage Options

While this sandwich is best enjoyed fresh off the griddle, you can store leftovers if needed. Here’s how:

Refrigeration: Wrap leftover sandwiches tightly in foil or plastic wrap and refrigerate for up to 2 days. Keep in mind that the bread may lose some crispness.
Reheating: Reheat sandwiches in a skillet over medium-low heat, flipping occasionally until warmed through. Alternatively, use an oven set to 350°F for about 10 minutes.
Freezing: While not ideal, you can freeze fully assembled but ungrilled sandwiches. Wrap them tightly in plastic wrap, then foil, and freeze for up to 1 month. Thaw before grilling for best results.

Variations and Substitutions

One of the best things about the Roast Beef Reuben is its adaptability. Here are some ideas to make this recipe your own:

Protein Swap: Not a fan of roast beef? Try turkey, pastrami, or even grilled chicken as an alternative. Each variation brings its own unique twist.
Bread Choices: Swap the rye bread for sourdough, ciabatta, or even a hearty multigrain. Gluten-free bread works too if needed.
Cheese Options: While Swiss is traditional, sharp cheddar, Havarti, or even pepper jack can add an exciting flavor twist.
Dressing Alternatives: Replace the Thousand Island dressing with Russian dressing, Dijon mustard, or even a creamy horseradish sauce for a bolder flavor.
Add-ons: Experiment with extras like caramelized onions, roasted red peppers, or even a fried egg for a deluxe version of the sandwich.

Feel free to get creative – this recipe is just a starting point for endless delicious possibilities.

With its rich flavors and easy preparation, the Roast Beef Reuben is sure to become a beloved addition to your recipe collection. Whether you’re serving it to family, friends, or simply treating yourself, this sandwich promises to satisfy every time. Happy cooking!
