Arby's Corned Beef Reuben Recipe: Swiss-Melted Sandwich With Tangy Sauce

This Arby's corned beef Reuben recipe brings the iconic sandwich to your kitchen with that signature Swiss-melted perfection and tangy sauce. 💛 The secret lies in using thinly sliced corned beef that stays tender yet firm, paired with perfectly toasted rye bread and melted Swiss cheese that stretches just right. I've perfected the balance between restaurant-quality and home-cooking simplicity—no shortcuts that sacrifice flavor.

The magic happens when you layer the corned beef, sauerkraut, and Swiss cheese between two slices of toasted rye, then grill it until the cheese melts into golden, stretchy perfection. The tangy Russian dressing ties everything together, creating that unmistakable Reuben flavor. This isn't just a sandwich—it's a full meal experience with every bite delivering that smoky, tangy, cheesy harmony.

What sets this recipe apart is the attention to detail: the bread must be toasted to a crispy golden brown, the cheese needs to melt evenly without burning, and the corned beef should be just warm enough to enhance its natural flavors. The sauerkraut adds that essential tangy crunch, while the Russian dressing provides the perfect balance of sweet and tangy notes. Once you try this version, you'll never settle for anything less than the real deal.

Whether you're hosting a game day gathering or craving a classic comfort meal, this Reuben delivers restaurant-quality results with minimal effort. The instructions are straightforward, and the ingredients are easy to find—making it the perfect sandwich for any occasion. Let's get started on recreating this iconic dish at home!

Ingredients for arby's corned beef reuben

Eight essential ingredients for that iconic Arby's Reuben flavor at home.

The corned beef is everything here. Deli-sliced is ideal, but if you're starting with a whole brisket, look for one with good marbling—it stays juicier. Costco or local butchers often have great options. For the Swiss cheese, Emmental or Gruyère work too, but classic Swiss melts best. The rye bread? Marble rye is perfect, but any dark rye will do. Toast it until it's crispy golden—no skipping this step, trust me. The sauerkraut should be jarred and drained, but if it's too sour, rinse it well before using.

No Russian dressing? Mix mayo, ketchup, and a splash of vinegar—it’s a solid stand-in. Short on mayo? Greek yogurt works too. The Dijon mustard adds depth, but if you don’t have it, yellow mustard at half the amount will do. For the pickle chips, any crunchy chips work—even potato chips in a pinch. The garlic powder is non-negotiable though; it’s what ties the whole sandwich together. If you’re feeling fancy, add a drizzle of honey to the Russian dressing for that extra-sweet touch.

Corned beef keeps for 4-5 days in the fridge, but use it within 3 days for best flavor. The rye bread stays fresh for 3-4 days if wrapped tightly, and the Swiss cheese can last up to 2 weeks in the fridge. For leftovers, wrap the sandwiches in foil and reheat in a skillet for 1-2 minutes per side—it’s the only way to get that perfect melt again. Freeze the filling (corned beef, cheese, sauerkraut) separately for up to 3 months if you want to assemble fresh later.

Step-by-step instructions for Arby's corned beef Reuben

Here's how to recreate that iconic sandwich at home—juicy corned beef, melted Swiss, and tangy sauce between crispy rye.

Heat 2 tablespoons vegetable oil in a large skillet over medium-high heat until shimmering. Add the 1 lb corned beef in a single layer and cook for 2-3 minutes per side until lightly browned but still tender. You want to warm it through without overcooking—it should be heated all the way through but still juicy when you cut into a piece.

Here's the thing—don't press down on the meat or it'll squeeze out all the flavor. If any slices stick, gently lift them with a thin spatula. Remove from heat and let rest for 2 minutes before assembling. This resting time keeps the meat juicy when you slice it later.

In a small bowl, combine the 0.5 cup Russian Dressing, 2 tablespoons mayonnaise, 1 teaspoon Dijon Mustard, 0.5 teaspoon garlic powder, 0.5 teaspoon kosher salt, and 0.25 teaspoon black pepper. Mix until completely smooth—this sauce is what ties everything together. I like to taste it at this stage to adjust seasoning if needed.

This sauce should be thick but still spreadable. If it's too thin, let it sit for 5 minutes to thicken slightly. The tangy Russian Dressing and creamy mayo combination is what gives that classic Reuben flavor. Don't skip the Dijon—it adds that necessary depth that store-bought sauces often miss.

Lay out 4 slices of rye bread on a clean work surface. Spread about 1 tablespoon of the sauce mixture on each slice. Then layer 2 slices of corned beef on each sandwich, slightly overlapping them. Place 2 slices of Swiss cheese on top of the meat—this is where the magic happens when it melts.

Add 1.5 tablespoons of drained sauerkraut to each sandwich (about 3 tablespoons total per sandwich), spreading it evenly. The sauerkraut should be well-drained—if it's too wet, pat it dry with a paper towel first. Top with the remaining 4 slices of rye bread to complete the sandwiches.

Heat a clean skillet over medium heat and melt the 2 tablespoons unsalted butter until foaming. Add the assembled sandwiches and cook for 3-4 minutes per side until the bread is golden brown and the cheese is fully melted. You'll see the cheese stretch and bubble—that's your signal it's ready.

Here's where it gets tricky: press down gently on each sandwich with a spatula for 10 seconds to help the cheese melt completely. Watch carefully—the bread should be crispy while the cheese remains gooey inside. If the bottom starts to burn before the top is done, reduce the heat slightly.

Transfer the sandwiches to a cutting board and let rest for 1 minute before slicing diagonally into halves or thirds. The sandwiches will be hot and gooey—this resting time helps everything set slightly so it's easier to handle. Arrange on a platter and sprinkle with the remaining sauce mixture if desired.

For that classic Arby's touch, serve with 0.25 cup pickle chips on the side. The crunch contrasts perfectly with the soft, melted sandwich. Cut into wedges and serve immediately while everything is warm and the cheese is still gooey. This sandwich is best enjoyed fresh out of the pan!

Storing and reheating your leftovers

Fridge Storage Tips

Store your corned beef Reuben sandwiches in an airtight container with parchment paper between layers to prevent sogginess. I wrap mine tightly in plastic wrap first, then place in a container with a lid. Keep them in the fridge for up to 2 days—the flavors actually meld better overnight, but the bread stays crispier when fresh. 🥪

Freezer-Friendly Assembly

Freeze the corned beef, Swiss cheese, and sauerkraut separately in a ziplock bag for up to 3 months. When ready to eat, toast the rye bread fresh, assemble the sandwich, and reheat in a skillet for 2-3 minutes per side over medium heat. This method preserves texture better than freezing the whole sandwich.

Reheating Perfection

For the best results, reheat sandwiches in a nonstick skillet with 1 tablespoon butter over medium heat for 3-4 minutes per side. Press down gently with a spatula for 10 seconds to remelt the cheese—this is the secret to that gooey, restaurant-style texture. Avoid microwaving; it makes the bread rubbery and the cheese grainy. 🔥

Sauerkraut Refresh

If your sauerkraut loses its crunch after storage, rinse it in cold water and pat dry with a paper towel. For extra tang, add 1 teaspoon apple cider vinegar to the drained sauerkraut before using. This trick revives the flavor and texture perfectly for sandwiches.

Bread Revitalization

Revive stale rye bread by toasting it in a skillet with 1 tablespoon butter for 1-2 minutes per side until golden and crispy. This step is non-negotiable—it recreates that essential Arby's crunch. For extra flavor, sprinkle with garlic powder while toasting. 🍞

Sauce Salvation

If your Russian dressing sauce separates after storage, whisk in 1 tablespoon mayonnaise to restore its creamy texture. For extra tang, add ½ teaspoon Dijon mustard or a dash of hot sauce. Store any leftover sauce in a small jar with a tight lid in the fridge for up to 5 days.
