History / Background

To understand Reuben sliders, we first need to appreciate the legendary Reuben sandwich itself—one of America’s most iconic deli creations. The original Reuben sandwich has a fascinating and hotly debated origin story that dates back to the early 20th century, with two main cities claiming bragging rights: Omaha, Nebraska, and New York City.

The Omaha story credits Reuben Kulakofsky, a Lithuanian-born grocer who supposedly created the sandwich around 1925 during late-night poker games at the Blackstone Hotel. The story goes that Kulakofsky assembled corned beef, Swiss cheese, sauerkraut, and Russian dressing on rye bread to feed his poker buddies. The sandwich was so beloved that it eventually appeared on the hotel’s restaurant menu. The Blackstone’s owner, Charles Schimmel, entered the sandwich in a national competition in 1956, where it took top honors and gained national attention.

The New York claim centers on Arnold Reuben, owner of Reuben’s Delicatessen, who allegedly created the sandwich in 1914 for actress Annette Seelos. His version quickly became popular with Broadway stars and the Manhattan elite, cementing the Reuben’s place in American culinary history.

Regardless of its true birthplace, the Reuben sandwich represents a beautiful fusion of culinary traditions—German (sauerkraut), Irish (corned beef), and Jewish-American deli culture (the rye bread and overall deli aesthetic). By the mid-20th century, it had become a staple in delicatessens across America, particularly in urban areas with strong Jewish and Eastern European immigrant communities.

The slider variation is a much more recent innovation, born from the modern trend of creating “party-sized” versions of classic dishes. Sliders themselves have an interesting history—the term originally referred to small burgers from White Castle, founded in 1921, which were small enough to “slide” down easily. The concept of making sliders from various sandwiches gained momentum in the 2000s, particularly with the rise of food blogs and Pinterest.

Reuben sliders likely emerged from home cooks and caterers looking for ways to serve the beloved sandwich format at parties and gatherings. The genius of baking them all together on Hawaiian rolls—with that buttery, slightly sweet bread creating the perfect contrast to the savory filling—transformed the Reuben into an easy, crowd-pleasing appetizer. The baked slider method, where multiple sandwiches are assembled together and baked as one unit, became wildly popular on Pinterest and food blogs around 2010-2015.

Today, these easy Reuben sliders represent the perfect marriage of nostalgic deli flavors and modern entertaining convenience. They honor the traditional sandwich while making it more accessible and party-friendly for today’s home cooks.

Ingredient Notes

Let’s break down what makes these Reuben sliders so incredibly delicious and why each ingredient matters:

Hawaiian Sweet Rolls – These soft, slightly sweet dinner rolls are the secret weapon! The sweetness beautifully balances the salty, tangy filling. King’s Hawaiian is the most popular brand, but store brands work great too. Look for them in the bakery section in a 12-pack. Substitution: Regular dinner rolls or slider buns work, but you’ll miss that signature sweet contrast.

Corned Beef – The star of the show! Use quality deli-sliced corned beef for best results. You can get it freshly sliced from the deli counter (ask for it sliced medium-thin) or buy pre-packaged corned beef. About 1 pound should give you plenty. Budget tip: Leftover St. Patrick’s Day corned beef, thinly sliced, is perfect for this. Substitution: Pastrami makes excellent “pastrami sliders” with a smokier flavor.

Swiss Cheese – Traditional for Reubens, Swiss cheese has that nutty, mild flavor and melts beautifully. Get sliced Swiss cheese from the deli for best melting quality. You’ll need about 12 slices. Substitution: Provolone or Gruyere work well if you can’t find Swiss, though the flavor will be slightly different.

Sauerkraut – This fermented cabbage brings the essential tangy punch that makes a Reuben a Reuben. It’s crucial to drain it VERY well—excess moisture will make your sliders soggy. Buy it in jars or cans in the condiment aisle. Important: Always squeeze it dry with paper towels! Substitution: If you find sauerkraut too tangy, rinse it first, though purists might argue this isn’t a true Reuben.

Thousand Island Dressing – This creamy, slightly sweet, tangy dressing is what ties everything together. Store-bought is perfect and convenient. Substitution: Russian dressing is very similar and equally traditional. Some people even prefer it!

Butter – Melted butter mixed with seasonings gets brushed on top, creating that golden, crispy, flavorful crust that makes these sliders irresistible. Don’t skip this step—it’s what elevates them from good to amazing.

Seasonings for Butter – Garlic powder, onion powder, and poppy seeds (or sesame seeds) add extra flavor to that buttery top. These are optional but highly recommended for that “wow” factor.

Dijon Mustard – A little mustard mixed into the butter adds depth and a subtle tang that enhances all the other flavors.

Equipment Needed

You won’t need any fancy equipment for these mini Reuben sandwiches—just basic kitchen tools:

• 9×13-inch baking dish – The perfect size for a 12-pack of rolls
• Sharp serrated knife – For cutting the rolls horizontally (crucial for clean cuts!)
• Cutting board – For prep work
• Small saucepan or microwave-safe bowl – To melt the butter
• Pastry brush – For brushing the butter mixture on top
• Aluminum foil – To cover the sliders while baking
• Paper towels – Essential for draining the sauerkraut thoroughly
• Colander or strainer – For draining sauerkraut
• Measuring cups and spoons – For accurate measurements
• Small mixing bowl – For the butter mixture

Optional but helpful:

• Parchment paper – Line the baking dish for easier cleanup
• Kitchen shears – Alternative to knife for separating sliders after baking

Tips & Variations

Rachel Sliders:
Swap the corned beef for deli turkey and replace the sauerkraut with coleslaw for “Rachel sliders”—another classic deli sandwich variation that’s equally delicious.

Pastrami Sliders:
Use pastrami instead of corned beef for a smokier, spicier flavor profile. Some people actually prefer these!

Extra Cheesy:
Add a layer of cream cheese spread on the bottom rolls before adding the other ingredients for an ultra-creamy, decadent version.

Spicy Reuben Sliders:
Mix a teaspoon of hot sauce or sriracha into your Thousand Island dressing, or add sliced jalapeños to the filling for a spicy kick.

Mini Version:
Use 24 mini dinner rolls instead of 12 standard slider rolls for bite-sized party appetizers perfect for cocktail parties.

Rye Flavor:
Can’t find rye slider buns? Mix 1 teaspoon of caraway seeds into your butter mixture to add that classic rye bread flavor to Hawaiian rolls.

Lighter Option:
Use reduced-fat Swiss cheese, light Thousand Island dressing, and reduce the butter to 2 tablespoons brushed more lightly for a lower-calorie version.

Vegetarian Sliders:
Replace corned beef with thick slices of roasted portobello mushrooms or tempeh “bacon” for a meat-free version that still delivers big flavor.

Pro Chef Tips

The Secret to Perfect Slicing: Freeze your connected rolls for 10 minutes before slicing. This firms them up slightly, making it much easier to cut through cleanly without squishing the soft bread.

Even Distribution is Key: When layering ingredients, make sure everything reaches all the way to the edges. The outer sliders deserve just as much filling as the middle ones!

Double-Butter Technique: For restaurant-quality richness, brush melted butter on the bottom of the rolls before adding fillings, then again on top. It adds extra flavor and helps prevent soggy bottoms.

The Rest Period Matters: Letting the sliders rest for 2-3 minutes after baking allows the cheese to set slightly and makes them much easier to handle without falling apart.

Cheese Placement Strategy: Place cheese directly on top of the sauerkraut (not the meat) so it melts down into the sauerkraut, creating a delicious, cohesive layer that holds everything together.

Butter Every Crevice: Don’t just brush the tops—use your pastry brush to get that butter mixture into every little valley between the rolls. This creates maximum flavor and that irresistible golden crust.

Temperature Check: If the tops are browning too quickly but the cheese isn’t fully melted, tent with foil and lower the oven temperature to 325°F for a few extra minutes.

The Toothpick Test: For parties, stick a decorative toothpick through each slider before baking (through the top). This makes them easy to identify and grab, plus they look more professional.

Common Mistakes to Avoid

Wet Sauerkraut: This is the number one mistake! If you don’t drain and squeeze your sauerkraut thoroughly, you’ll end up with soggy, mushy sliders. Really wring it out aggressively—you can’t over-do it.

Separating the Rolls Too Early: Don’t separate the individual rolls until after baking! Keeping them connected makes assembly infinitely easier and helps them stay moist during baking.

Skipping the Covered Baking Step: Baking covered first is crucial—it allows the cheese to melt and everything to heat through without burning the tops. Don’t skip straight to uncovered baking.

Over-Browning the Tops: Watch carefully during that final uncovered baking time. Every oven is different, and you want golden brown, not dark brown or burnt. Check at 5 minutes.

Not Enough Sauce: Don’t be stingy with the Thousand Island dressing! You need enough to keep these sliders moist and flavorful. Spreading it on both the top and bottom helps tremendously.

Using Cold Ingredients: If your corned beef and cheese are ice-cold from the fridge, they’ll take longer to heat through and may result in overcooked bread. Let them sit at room temperature for 15 minutes before assembly.

Forgetting to Spray the Pan: Always grease your baking dish! Even with the butter on top, the bottoms can stick, and there’s nothing worse than half your slider staying in the pan.

Storage & Meal Prep

Refrigerator Storage:
Leftover Reuben sliders can be stored in an airtight container in the refrigerator for up to 3 days. For best results, wrap them individually in foil or plastic wrap to keep them from drying out. They won’t be quite as crispy as fresh, but they’ll still be delicious!

Reheating Methods:
The best way to reheat is in the oven to restore some of that crispy top. Preheat to 325°F, wrap sliders in foil, and heat for 12-15 minutes until warmed through. You can also microwave individual sliders for 30-45 seconds, but they’ll be softer. For a crispier result, microwave first, then finish in a 400°F oven for 3-4 minutes.

Toaster Oven Method:
Perfect for reheating 1-2 sliders! Wrap in foil and heat at 325°F for 8-10 minutes. Remove foil for the last 2 minutes to crisp up the top.

Individual Portioning:
If you’re meal prepping, separate and wrap individual sliders after they’ve cooled. This makes grabbing a quick lunch or snack super convenient throughout the week.

Party Leftovers:
These actually make fantastic next-day lunches! The flavors have had time to meld even more, creating an incredibly tasty sandwich.

Make-Ahead & Freezer Notes

Advance Assembly:
These are PERFECT for make-ahead entertaining! Assemble the sliders completely (through adding the top roll) up to 4 hours before baking. Cover tightly with plastic wrap and refrigerate. When ready to bake, prepare the butter mixture, brush it on top, and bake as directed, adding 5 extra minutes to the covered baking time since they’ll be cold.

Overnight Preparation:
You can even assemble these the night before! Just don’t add the butter topping until you’re ready to bake. Cover tightly and refrigerate overnight, then add butter topping and bake as directed in the morning or before your party.

Freezing Unbaked Sliders:
Assemble the sliders completely in a disposable aluminum baking pan, cover very tightly with plastic wrap and then aluminum foil, and freeze for up to 1 month. Don’t add the butter topping before freezing. To bake from frozen: Thaw overnight in the refrigerator, add butter topping, and bake as directed.

Freezing Baked Sliders:
While these are best fresh, you can freeze baked sliders. Cool completely, wrap individually in plastic wrap, then place in a freezer bag for up to 2 months. To reheat from frozen: Unwrap, place on a baking sheet, cover with foil, and bake at 325°F for 20-25 minutes until heated through.

Best Freezer Strategy:
Honestly, these are so quick to assemble that I prefer freezing them unbaked rather than baked. The texture is much better when they’re freshly baked rather than reheated.

Serving Suggestions

These baked Reuben sliders are incredibly versatile and work beautifully with so many different sides and occasions:

Classic Deli Sides:
Serve with dill pickle spears, potato chips, coleslaw, or potato salad for that authentic deli experience. A crispy dill pickle on the side is practically mandatory!

Hot Sides:
Pair with French fries, sweet potato fries, tater tots, or crispy potato wedges for a more substantial meal.

Salad Pairings:
Balance the richness with a crisp green salad, Caesar salad, or a tangy German potato salad. The freshness cuts through beautifully.

Soup Combinations:
These pair wonderfully with tomato soup, French onion soup, potato soup, or a light vegetable soup for a cozy, comfort-food meal.

Game Day Spread:
Serve as part of a larger game day spread with wings, nachos, chips and dip, and vegetable platters for variety.

Party Platter:
Create an impressive appetizer table by serving these alongside other finger foods like mozzarella sticks, jalapeño poppers, and chicken skewers.

Beverage Pairings:
These go great with beer (pilsners, lagers, or IPAs work wonderfully), hard cider, iced tea, or lemonade. For wine drinkers, try a crisp Riesling or Pinot Grigio.

Extra Dipping Sauces:
While Thousand Island is traditional, offer additional options like spicy brown mustard, honey mustard, or horseradish sauce for variety.

FAQs Section

Can I use different types of bread?
Absolutely! While Hawaiian rolls are traditional and provide that delicious sweet-savory contrast, you can use regular dinner rolls, slider buns, or even small potato rolls. Rye rolls would be incredibly authentic, though they’re harder to find in the connected format.

Do these really need to be baked, or can I just assemble them cold?
Baking is what makes these special! The heat melts the cheese into gooey perfection, melds all the flavors together, and creates that irresistible buttery, golden crust on top. Cold assembled sandwiches just won’t have the same magic.

Can I make these in advance for a party?
Yes! This is one of the best features of this recipe. Assemble them completely (except for the butter topping) up to 4 hours ahead, cover, and refrigerate. Add the butter topping and bake right before serving. Your guests will be amazed when you pull these hot, melty sliders from the oven!

Why are my sliders soggy?
Nine times out of ten, this is because the sauerkraut wasn’t drained well enough. You need to really squeeze out all that liquid. Also, make sure you’re not using too much Thousand Island dressing, which can also contribute to sogginess.

Can I substitute the Hawaiian rolls with regular hamburger buns?
You can, but you’ll need to assemble them individually rather than as one connected unit, which takes more time. The beauty of this recipe is the convenience of the connected rolls. If you use individual buns, reduce baking time by about 5 minutes.

How do I keep the tops from getting too brown?
If your oven runs hot or the tops are browning too quickly, tent the pan with foil during the uncovered baking phase. You want golden brown, not dark brown. Also, make sure your oven rack is in the center position, not too close to the top heating element.

Are these appropriate for a brunch or lunch?
Absolutely! While often served as appetizers, these make a fantastic lunch or brunch main dish. Serve 2-3 sliders per person with sides for a complete meal.

Can I make a vegetarian version?
Yes! Replace the corned beef with roasted portobello mushrooms, tempeh bacon, or even extra sauerkraut and cheese for a vegetarian version. You could also use plant-based deli slices if available in your area.
