Why This Reuben Slider Recipe is a Must-Try
Reuben sliders are essentially a scaled-down, more shareable version of the beloved Reuben sandwich.

This recipe shines for several reasons, making it a staple in many kitchens:

- Flavor Harmony: The combination of savory corned beef, sharp Swiss cheese, tart sauerkraut, and sweet-and-tangy Thousand Island dressing creates a symphony of flavors that is both comforting and exciting. The buttery, seasoned bun tops add an extra layer of deliciousness and visual appeal.

While often associated with St. Patrick’s Day, these delightful sliders are a fantastic option year-round. Whether you’re using freshly cooked corned beef or convenient deli slices, this recipe offers a quick and satisfying meal or appetizer that everyone will rave about. Let’s dive into the delicious details!
Essential Ingredients for Perfect Reuben Sliders
Gathering your ingredients is the first step to creating these incredible sliders. Here’s a detailed look at what you’ll need and some helpful tips for each component. You’ll find all precise measurements and instructions in the printable recipe card at the very end of this post.
Ingredient Spotlight & Smart Substitutions
Each ingredient plays a crucial role in building the signature Reuben flavor. Here’s what you need to know and how you can customize it:
- CORNED BEEF: We typically cook a 2.5-pound corned beef, often in an Instant Pot or Crockpot, which yields about 1.25 pounds of cooked meat. This is a fantastic recipe for utilizing leftover corned beef! For convenience, feel free to use high-quality deli corned beef, either pre-sliced or a whole piece that you can dice or shred at home. If using deli meat, choose a thicker cut for better texture. Shredding or cutting the meat into smaller pieces ensures a more manageable slider that doesn’t fall apart when bitten into.
- SAUERKRAUT: This tangy, fermented cabbage is non-negotiable for a true Reuben. The key to preventing soggy sliders is to thoroughly drain excess moisture from the sauerkraut. You can achieve this by placing it in a fine-mesh sieve and pressing out the liquid, or by squeezing it in a cheesecloth or clean kitchen towel until it’s relatively dry. This step makes a significant difference in the final texture of your sliders.
- SWISS CHEESE: Classic Swiss cheese slices are our go-to, providing that signature nutty flavor and beautiful melt. However, you can certainly experiment with shredded Swiss cheese or even other melty cheeses like Gruyere, Emmental, or provolone for a slightly different flavor profile. Mozzarella could work in a pinch if you prefer a milder cheese.
- BUNS: The foundation of your slider! Regular slider buns work perfectly, as do sweet Hawaiian rolls, which add a lovely hint of sweetness that complements the savory fillings. For a unique twist and a bit more chew, mini pretzel rolls are an excellent choice. Choose whichever you enjoy most, ensuring they are fresh and soft.
- DRESSING: Thousand Island dressing is the traditional sauce for Reuben sandwiches, offering a creamy, tangy, and slightly sweet counterpoint to the rich meat and sharp cheese. If you prefer, Russian dressing is a very similar alternative, often with a bit more spice from horseradish or chili sauce. For those who love a bit of heat, a horseradish sauce could also be a delicious swap, or even a spicy brown mustard for a different kick.
- TOPPINGS & GARNISHES: To add an extra layer of texture and flavor, consider a sprinkle of Everything Bagel seasoning (our personal favorite!) or simple poppy seeds on the buttery tops of the buns before baking. For serving, some people enjoy adding crisp pickle slices, a side of coleslaw, or even pickle relish for a burst of freshness and tang. These are entirely optional but can elevate the experience!
Step-by-Step: Crafting Your Delicious Reuben Sliders
These step-by-step photos and instructions are designed to help you visualize each stage of making this recipe. For a convenient printable version, complete with all measurements and detailed instructions, simply Jump to Recipe at the bottom of this page.
- Prepare Your Pan: Begin by preheating your oven to 350°F (175°C). Lightly spray a 13×9 inch baking pan (or an 11×7 inch pan for a tighter fit) with non-stick cooking spray. This prevents sticking and ensures easy removal of your baked sliders.
- Prep the Corned Beef: Take your cooked corned beef and cut it into small, bite-sized pieces or shred it finely. This is a crucial step for easy eating. In our step photos, you might notice larger slices, which can make the sliders a bit harder to handle. Smaller pieces ensure every bite is perfect and prevents the fillings from pulling out.
- Arrange the Buns: If your slider buns are not already separated, carefully slice them horizontally through the middle. Place the bottom halves of the buns in a single layer into your prepared baking pan. Don’t worry if they fit snugly; that’s ideal for a cohesive slider pull-apart tray.
- Layer the Fillings: Evenly distribute the prepared corned beef over the bottom bun halves. Follow this with a generous layer of the well-drained sauerkraut, spreading it over the meat. Finally, cover the sauerkraut with the Swiss cheese slices, ensuring good coverage for maximum melt.
- Add the Dressing: Drizzle or spread the Thousand Island dressing evenly over the Swiss cheese layer. This creamy dressing is essential for the classic Reuben flavor and helps bind everything together.
- Top and Season: Place the top halves of the slider buns back onto your layered sandwiches. In a small bowl, melt the butter, then brush it generously over the tops of all the buns. Finally, sprinkle your choice of Everything Bagel seasoning or poppy seeds over the buttered tops for an extra burst of flavor and a beautiful golden crust.
- Bake to Perfection: Place the uncovered baking pan into your preheated oven and bake for approximately 20 minutes. The sliders are ready when the cheese is gloriously melted, the corned beef is heated through, and the tops of the buns are golden brown and slightly crispy.
Frequently Asked Questions & Expert Tips for Reuben Sliders
Absolutely! Reuben sliders are fantastic for making ahead, especially if you’re preparing for a party. I recommend assembling them a few hours, or even up to a day, before you plan to bake and serve. The key to successful make-ahead sliders is ensuring your sauerkraut is squeezed extremely dry to prevent the buns from becoming soggy. Also, for optimal freshness and texture, hold off on adding the Thousand Island dressing, melted butter, and seasoning until just before baking. Once assembled (without dressing/butter/seasoning), cover the baking pan tightly with plastic wrap and store it in the refrigerator. When you’re ready to bake, remove from the fridge, add the dressing, brush with melted butter, and sprinkle with seasoning before popping them into the oven.
If you happen to have any leftovers (a rare occurrence with these!), store them in an airtight container in the refrigerator for up to 3 days. To reheat, place the sliders on a baking sheet or in a baking pan and cover them loosely with aluminum foil to prevent the buns from drying out. Bake in a preheated 325°F (160°C) oven for about 10-15 minutes, or until they are warmed through and the cheese is re-melted. For an even quicker and crispier reheat, I often use my air fryer on the reheat function, which works wonderfully to restore their delicious texture.
While regular plain slider buns are perfectly fine, experimenting with different types can elevate your sliders! Hawaiian sweet rolls add a subtle sweetness that beautifully complements the savory corned beef and tangy sauerkraut. For a more robust flavor and chewy texture, mini pretzel buns are an excellent choice that pairs well with the salty and savory elements. Brioche slider buns also offer a rich, buttery flavor and a soft texture. The most important thing is to choose fresh, soft buns that can hold up to the hearty fillings.
While traditional Reuben sliders feature corned beef, you can definitely adapt the recipe! If you’re a fan of pastrami, it’s a fantastic substitute for a classic “Rachel” sandwich twist. You could also try thinly sliced roast beef for a different flavor profile. Just remember that the unique brined flavor of corned beef is what gives a Reuben its distinctive taste, so be aware that other meats will alter the overall profile.
Reuben sliders are quite hearty on their own, but they pair wonderfully with a variety of side dishes. For a classic deli experience, serve them alongside a crisp dill pickle spear or some extra coleslaw. Potato salad, a simple green salad with a light vinaigrette, or even a bowl of warm potato chips are also excellent choices. For a more substantial meal, consider a cup of tomato soup or a side of crispy oven-baked fries.
Serving Your Delicious Reuben Sliders
Once your Reuben sliders emerge from the oven, glistening and golden, allow them to cool for just a few minutes before serving. The melted cheese and hot fillings can be quite hot, and a brief rest also helps the flavors meld. We love to serve them brushed with melted butter and generously sprinkled with Everything Bagel seasoning (or simple poppy seeds for a classic look) for that extra touch of texture and flavor.
These mini sandwiches are naturally a huge hit around St. Patrick’s Day, providing a fun and flavorful way to celebrate. However, their deliciousness isn’t limited to one holiday! We frequently make them for game nights, casual weekend lunches, and even as a speedy and satisfying weekday dinner because everyone absolutely loves them. Arrange them artfully on a large platter for an impressive presentation that invites everyone to dig in. Pair them with a simple side like crunchy potato chips, a fresh green salad, or some dill pickles for a complete and satisfying meal.
