Make It Your Way

One of the best things about this Crispy Reuben Sandwich Recipe is how easy it is to make it truly your own. Whether you like it extra cheesy, a bit tangier, or with a different protein twist, small tweaks can bring a whole new vibe to this classic.

Swap the Meat: If you prefer something lighter or just want to try a different flavor, swapping corned beef for pastrami adds a smoky, peppery punch. I once combined half corned beef and half pastrami — the blend was gorgeous and full of depth.
Change up the Cheese: While Swiss cheese is the classic melt, I love experimenting with Gruyère or Havarti. They melt beautifully and add their own unique nutty or creamy notes.
Make it Vegetarian: Skip the meat altogether and layer your sandwich with marinated tempeh or sautéed mushrooms for a hearty vegetarian spin. Adding extra Swiss and sauerkraut keeps that signature tang and richness.
Try a Different Bread: Dark rye is ideal, but sometimes I use marble rye or even pumpernickel for a slightly sweeter or more robust bread flavor. Just make sure it’s sturdy enough to hold all the fillings together.
Butter vs Mayo for Crispiness: While softened butter on the outside is perfect for a golden crust, spreading mayonnaise instead gives a lovely tang and extra crunch. I recommend trying both to see which you like best!
Double the Dressing: If you love that creamy thousand island flavor, try adding a little extra inside your sandwich. Just be careful to drain the sauerkraut really well to avoid sogginess.

Step-by-Step: How I Make Crispy Reuben Sandwich Recipe

The image shows a toasted sandwich held by a woman's hand, split in half revealing multiple layers inside. The top and bottom layers are dark brown, grilled rye bread with visible grill marks. Inside, there are several layers of pinkish sliced meat stacked thickly in the middle. Under the meat, there is a layer of creamy melted white cheese that stretches slightly from the sandwich. Below the cheese, there is a layer of thin, light-colored shredded cabbage or sauerkraut adding texture. The sandwich is placed on a wooden surface with another half resting in front. photo taken with an iphone --ar 2:3 --v 7

Step 1: Lay the Flavor Foundation

Start by laying out two slices of hearty dark rye bread on your cutting board. Sprinkle a generous ½ cup of shredded Swiss cheese on each slice, covering it evenly. The cheese is the melty magic here, so don’t be shy. Next, drizzle about 2 tablespoons of thousand island dressing over the cheese on each slice, adding that creamy tang which is so signature to the sandwich. Then, layer half of your thinly sliced corned beef evenly over the dressing. Top that with half of the well-drained sauerkraut—this helps keep the sandwich crisp inside. Finally, cap each with the remaining two bread slices. Spread about a tablespoon of softened butter on the outside of the top bread slice, readying it to crisp up in the pan.

Step 2: Prep the Pan for Perfect Crisp

Heat a large skillet over medium heat — this is the sweet spot. Medium heat ensures the outside of your sandwich crisps up golden and buttery while gently melting the cheese inside without burning the bread. Patience here is key to getting that flawless texture.

Step 3: Grill to Golden Perfection

Place your sandwiches butter-side-down in the hot skillet. Listen for that satisfying sizzle! Let them cook undisturbed for about 3 minutes until the bread turns a gorgeous golden brown and feels crispy to the touch. While that side cooks, spread the remaining butter on the outside of the top slices—you'll get that even buttery crunch on both sides. When ready, carefully flip the sandwiches and cook the other side for another 2 to 3 minutes. This side will crisp up nicely and the cheese inside will melt to gooey perfection.

Step 4: Rest, Slice, and Serve

Once both sides are golden and the cheese is melted, transfer the sandwiches to a cutting board. Let them rest for just a minute so the molten cheese settles a bit—this makes slicing easier and prevents a gooey mess. Then cut each sandwich in half and serve immediately for best flavor and that perfect crispy-soft contrast in every bite.

Top Tip

Mastering the Crispy Reuben Sandwich Recipe is all about balancing texture and flavor. These tips have saved me from soggy sandwiches, burnt bread, and bland bites — so I’m excited to share them with you!

Drain the Sauerkraut Thoroughly: I learned the hard way that excess moisture from sauerkraut ruins the crispiness — always press out as much liquid as possible for that perfect crunch.
Use Medium Heat: Cooking on medium heat ensures golden, crispy bread and fully melted cheese. Too hot, and you risk burnt bread; too low means a limp sandwich.
Butter the Outside Generously: Spreading softened butter on the bread's exterior creates that irresistible golden crust that locks in flavor and crunch.
Flip Carefully and Only Once: Flipping the sandwich just once after the first side crisps helps the sandwich hold together and ensures even cooking.

How to Serve Crispy Reuben Sandwich Recipe

The left side shows plain slices placed one above the other, showing a soft, porous texture with small holes. On the right side, the two slices are topped with a thick layer of shredded white cheese, covering almost the entire surface of each slice. The cheese shreds have a slightly curly texture and are piled loosely, giving a fluffy look. The background is a white marbled texture. Photo taken with an iphone --ar 2:3 --v 7

Garnishes

Keep it simple yet classic with crisp dill pickle spears or tangy pickled red onions on the side. A sprinkle of freshly ground black pepper or a small handful of fresh parsley adds a nice pop of color and freshness to your plate. For a little extra zing, a drizzle of extra thousand island dressing or some spicy mustard makes a perfect dipping partner.

Side Dishes

The Crispy Reuben Sandwich pairs beautifully with classic deli-style sides such as kettle-cooked potato chips, crispy French fries, or a simple mixed green salad dressed with vinaigrette. For a heartier meal, creamy coleslaw or a warm bowl of tomato soup bring a comforting balance to the tangy sauerkraut and rich cheese.

Make Ahead and Storage

Storing Leftovers

Wrap any leftover sandwiches tightly in plastic wrap or foil and store them in the refrigerator. They will keep well for up to 2 days, maintaining much of that delicious flavor but starting to lose some crispiness.

Freezing

You can freeze a Crispy Reuben Sandwich, but it's best to assemble without the buttered bread exterior and freezing before cooking. Wrap tightly in freezer-safe foil or bags and freeze for up to a month. Thaw overnight in the refrigerator before cooking to avoid sogginess.

Reheating

To reheat, pop your sandwich into a preheated skillet or air fryer. This method crisps the bread back up nicely without making your sandwich soggy like the microwave would. Heat for about 3–4 minutes on medium heat until warmed through and golden crisp again.

Frequently Asked Questions:

Can I substitute pastrami for corned beef in this Crispy Reuben Sandwich Recipe?

Absolutely! Pastrami offers a smokier, peppery flavor compared to corned beef's milder taste. You can even mix both for a flavorful twist on the classic sandwich.

How do I prevent my sandwich from getting soggy?

Drain your sauerkraut thoroughly to avoid excess moisture. Also, cooking the sandwich on medium heat with butter on the outside helps create a barrier, keeping the bread crispy.

Can I use a different type of cheese instead of Swiss?

Yes, Gruyère, Havarti, or Provolone are excellent substitutes that melt well and complement the flavors in the sandwich beautifully.

What’s the best way to reheat a leftover Crispy Reuben Sandwich?

Reheat leftovers in a skillet or air fryer to regain that crispy texture. Avoid microwaving since it makes the sandwich soggy.
