Arby's Corned Beef Reuben Recipe: Swiss-Melted Layers That Rival the Classic

This Arby's corned beef Reuben recipe delivers the iconic sandwich experience you know and love—tender corned beef, melted Swiss cheese, and tangy sauerkraut between perfectly toasted rye bread.

The secret lies in slow-braised corned beef that stays juicy and flavorful, paired with a crispy bread exterior that holds up to every bite. I've recreated this classic sandwich after years of perfecting the balance between rich, savory flavors and that signature tangy crunch.

The key to authentic results starts with the corned beef—slow-cooked until fork-tender yet retaining its natural juices. We'll build the sandwich with proper layering: sauerkraut first for that essential tang, followed by melted Swiss cheese that creates a creamy, gooey center.

The rye bread gets toasted just enough to crisp up without burning, ensuring it can hold all those flavorful layers without falling apart.

What makes this recipe truly special is the combination of textures and flavors working in perfect harmony—crispy bread, tender beef, creamy melted cheese, and the bright acidity of sauerkraut.

Each element has been tested and refined to deliver that same satisfying bite you remember from Arby's, but with the flexibility to make it at home whenever cravings strike.

Serve with classic sides like potato chips or a simple coleslaw to complete the experience. This isn't just a sandwich—it's a nostalgic meal that brings back memories of your favorite fast-food classic, now made with restaurant-quality techniques in your own kitchen.

Ingredients for arby's corned beef reuben

Four slices of toasted rye, tender corned beef, and Swiss that melts just right.

The corned beef is everything here. Look for pre-cooked brisket at the deli counter—it should be fork-tender but not falling apart. Costco or local butchers often have the best quality, but the regular supermarket deli works too. If you're starting from scratch, slow-cook it with garlic powder, black pepper, and a bay leaf for that authentic tang. The Swiss cheese? Semi-soft slices melt best—avoid the super-hard stuff. Rye bread matters too—dark rye with a good crunch holds up better than light varieties.

No Russian dressing? Mix mayo, pickle relish, white vinegar, sugar, and a pinch of salt—it's easier than you'd think. Sauerkraut too sour? Rinse it under cold water to mellow the flavor. Substitute sauerkraut with quick-pickled red cabbage if you're feeling adventurous. The mustard is non-negotiable—it adds that signature tang. For the corned beef, if you can't find pre-cooked, slow-cook a brisket with spices until it's fall-apart tender. And yes, you can make this ahead—assemble the sandwiches and refrigerate them for up to 24 hours before toasting.

This sandwich is best eaten fresh off the grill, but leftovers reheat beautifully. Wrap in foil and warm in a 350°F oven for 10 minutes to revive the crispiness. Store components separately: corned beef in the fridge for 3-4 days, cheese wrapped in parchment, and bread in a sealed bag. The Russian dressing keeps for 1 week in the fridge. Pro tip: Toast the bread just before serving—that's when it gets its perfect crunch.

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

Let's build this iconic sandwich layer by layer—just like the original.

Start by slicing the 1.5 lb corned beef brisket into thin strips about ¼-inch thick. If your brisket is pre-cooked, you can slice it right away. For slow-braised brisket, make sure it's fully cooled before slicing—this prevents the meat from tearing. Arrange the slices on a cutting board and season lightly with ½ tsp garlic powder, ½ tsp black pepper, and 1 tsp salt. This step ensures every bite has that signature Arby's flavor without overpowering the sandwich.

Here's the thing—don't skip this seasoning. The corned beef already has salt from the curing process, so go easy with the extra seasoning. You want to enhance, not dominate. If you're using pre-sliced corned beef from the deli, check for any excess saltiness first. Some brands are saltier than others, and you don't want to ruin the balance.

In a small bowl, combine 2 tbsp mayonnaise, 2 tbsp dill pickle relish, 1 tbsp white vinegar, and 1 tsp sugar. Mix well until everything is fully incorporated and smooth. This dressing is the secret weapon of the Reuben—it cuts through the richness of the cheese and corned beef while adding that classic tangy sweetness. If you're using store-bought Russian dressing, you can skip this step, but making it fresh gives you that authentic Arby's taste.

Let the dressing sit for 5 minutes before using it. This resting time allows the flavors to meld together, creating a more cohesive taste. If you're in a hurry, you can use it immediately, but that extra time makes a noticeable difference in the final sandwich. Trust me, it's worth the wait.

Lightly toast the 4 slices rye bread in a dry skillet over medium heat for about 1-2 minutes per side, until they're just golden brown. You want the bread to be warm and slightly crispy, but not burnt. The toasting adds texture and prevents the sandwich from becoming soggy. If you prefer a softer bread, you can skip toasting, but I always recommend it for that classic Reuben crunch.

While the bread is toasting, drain and rinse the 1.5 cups sauerkraut if it's too sour. The goal is to keep the tang without making the sandwich taste like vinegar. Pat the sauerkraut dry with a paper towel to remove any excess moisture. This step is crucial—wet sauerkraut will make your sandwich soggy, and you don't want that.

Spread 2 tbsp yellow mustard on one side of each toasted rye slice. This adds an extra layer of tangy flavor that balances the richness of the cheese and corned beef. On one slice of bread, layer ¼ of the sauerkraut, followed by ¼ of the sliced corned beef brisket. Repeat this layering process with the remaining sauerkraut and corned beef on the other slice. The key here is to distribute everything evenly so each bite has the perfect mix of flavors.

Now for the cheese—place 1 oz of Swiss cheese on each layer of corned beef. The Swiss cheese should be sliced thinly so it melts evenly and doesn't overwhelm the sandwich. If you're using pre-sliced cheese, make sure it's semi-soft for easy melting. This is where the magic happens—the cheese melts into the corned beef and sauerkraut, creating that gooey, Swiss-melted goodness that makes this sandwich legendary.

To assemble the sandwich, place one slice of bread (mustard-side down) on a plate, then add the second slice (mustard-side up) on top of the cheese and corned beef layer. Spread 2 tbsp of the Russian dressing evenly over the top slice. Now, here's the critical part—cover the sandwich with a piece of aluminum foil and place it in a 350°F oven for 5-7 minutes. This gentle heating melts the cheese perfectly without drying out the bread.

Once the cheese is fully melted and the sandwich is heated through, remove it from the oven. Let it rest for 2 minutes before cutting diagonally into two triangles. This resting time allows the layers to set slightly, making it easier to handle and ensuring the first bite is as perfect as the last. Serve immediately while everything is warm and gooey—this sandwich doesn't wait!

Troubleshooting this dish

Bread Too Soggy

If your rye bread turns soggy, it's usually from excess moisture in the sauerkraut or Russian dressing. Start by patting the sauerkraut completely dry with paper towels to remove all liquid.

For extra insurance, I recommend toasting the bread for 30 seconds longer on each side to create a stronger barrier. Also, use less dressing—just 1 tbsp per sandwich instead of 2 tbsp. The dressing should complement, not drown, the other flavors. 🥖

Cheese Not Melting

Swiss cheese needs the right conditions to melt properly. First, ensure you're using semi-soft slices—harder cheeses won't melt as smoothly. When assembling, place the cheese directly on the corned beef, not on the bread. Cover the sandwich tightly with aluminum foil and bake at 350°F for 5-7 minutes.

If your oven runs hot, reduce to 325°F to prevent burning. For extra help, sprinkle a pinch of salt on top before melting—it lowers the melting point slightly. 🧀

Corned Beef Too Dry

Pre-sliced deli corned beef can dry out quickly, especially if it's been sitting out. To fix this, slice the beef just before assembling the sandwich. If it's already dry, try reheating it in a skillet with 1 tbsp beef broth or water over low heat for 2-3 minutes.

The moisture will revive the texture without making it mushy. For future batches, store pre-sliced corned beef in airtight containers with a damp paper towel to keep it moist. 🥩

Sauerkraut Too Sour

If your sauerkraut tastes overly acidic, rinse it under cold water for 30 seconds and drain well. For a milder flavor, mix in 1 tsp sugar or ½ tsp honey to balance the tang. Another trick is to use quick-pickled red cabbage instead—it has a similar texture but less acidity.

If you're short on time, squeeze the sauerkraut in a clean kitchen towel to remove excess liquid before layering. 🥬

Russian Dressing Too Thin

A runny Russian dressing can make your sandwich messy. To thicken it, mix in ½ tsp cornstarch or 1 tsp grated carrot and let it sit for 5 minutes to absorb the moisture.

If you're making it from scratch, reduce the mayo slightly to 1.5 tbsp and add ½ tsp Dijon mustard for better body. For store-bought dressings, look for ones labeled "thick" or "creamy" to avoid this issue altogether. 🥫

Sandwich Falling Apart

If your Reuben crumbles when you cut it, the bread likely wasn't toasted enough or the layers weren't pressed together firmly.

Next time, toast the bread until it's golden brown and slightly crispy, then press the sandwich together in the oven under a small weight (like a cast-iron skillet) for 1 minute before baking. Also,
