What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples, and a few are easy to source from your local deli or grocery store.

• Slider buns (12 small, soft rolls; I love King’s Hawaiian for their sweet, tender crumb)
• Corned beef (about 1 pound thinly sliced; deli-style or leftover cooked corned beef works great)
• Swiss cheese slices (12 slices; opt for good-quality Swiss for meltiness and flavor)
• Sauerkraut (1 cup, drained; or quick-pickle shredded cabbage for a fresher crunch)
• Unsalted butter (3 tablespoons, softened; for toasting the buns)
• For the Tangy Thousand Island Sauce:
• 1/2 cup mayonnaise (I prefer Hellmann’s for creaminess)
• 2 tablespoons ketchup
• 1 tablespoon sweet pickle relish (adds a nice zing)
• 1 teaspoon Worcestershire sauce
• 1 teaspoon apple cider vinegar (for a little brightness)
• 1/2 teaspoon garlic powder
• Salt and pepper to taste

You can swap the slider buns for gluten-free rolls if needed, and I’ve also tried turkey pastrami as a leaner alternative to corned beef—both work wonderfully. For a dairy-free take, substitute vegan cheese and mayonnaise, which still gives you that creamy, tangy vibe.

Equipment Needed

• A large skillet or griddle (non-stick works best for even toasting of the sliders)
• Mixing bowl (for the Thousand Island sauce)
• Spatula or tongs (to flip and press the sliders gently)
• Measuring spoons and cups (for precise sauce mixing)
• Baking sheet or pan (optional, if warming sliders in the oven afterward)

If you don’t have a skillet, a cast iron pan or even a sandwich press can work just fine. I once used a George Foreman grill on a whim, and it gave a fun crispness, though the sliders cook faster so watch closely. For butter spreading, a silicone brush helps evenly coat buns without waste. Keep your skillet well-seasoned or non-stick for best results, and don’t rush the toasting—it’s the key to that coveted crispy exterior.

Preparation Method

1. Make the Thousand Island Sauce: In a small mixing bowl, combine 1/2 cup mayonnaise, 2 tablespoons ketchup, 1 tablespoon sweet pickle relish, 1 teaspoon Worcestershire sauce, 1 teaspoon apple cider vinegar, and 1/2 teaspoon garlic powder. Stir well until smooth. Season with salt and pepper to taste. Set aside in the fridge to let flavors meld (about 10 minutes).
2. Prepare the Slider Buns: Slice the slider buns in half horizontally. Spread softened butter evenly on the cut sides of all buns—this will help create that golden, crispy crust.
3. Toast the Bottom Buns: Heat a large skillet over medium heat. Place the bottom halves of the buns buttered side down in the skillet. Toast until golden brown and crispy, about 2–3 minutes. Remove and set aside.
4. Assemble the Sliders: On each toasted bottom bun, layer approximately 1.5 ounces (about 45 grams) of corned beef, then a heaping tablespoon of sauerkraut or quick-pickle cabbage slaw, and top with a slice of Swiss cheese.
5. Toast the Top Buns: Butter the top halves of the buns and place them buttered side down in the skillet until golden and crispy, about 2 minutes.
6. Combine & Melt: Carefully place the assembled bottom buns back into the skillet, cheese side up. Top each with the toasted bun halves. To melt the cheese and warm through, lower the heat to medium-low and cover the skillet with a lid or foil for 3–5 minutes. Peek to make sure cheese is melty but buns don’t burn.
7. Serve with Sauce: Remove sliders from the skillet, slice if needed, and serve immediately with a generous dollop of the tangy Thousand Island sauce on the side or spread on the top bun before assembling for an extra kick.

Quick tip: If you notice the buns are browning too fast before the cheese melts, lower the heat and cover the pan—it traps heat and melts cheese without scorching the bread. Also, pressing gently with your spatula helps the layers stick together nicely.

Cooking Tips & Techniques

When it comes to these Crispy Reuben Sandwich Sliders, timing and layering matter more than you might expect. Buttering the buns evenly is critical—too little, and you won’t get that perfect crisp; too much, and things get greasy. I’ve learned the hard way that medium heat is your friend here, letting the buns toast slowly without burning.

Don’t rush melting the cheese! Covering the pan traps steam and heat, which is a simple trick to get gooey Swiss cheese without overcooking the meat or drying out the bread. Also, draining your sauerkraut well (or quick-picking cabbage with minimal liquid) keeps the sliders from getting soggy—a common pitfall.

One time, I skipped toasting the buns first, and the sliders turned out mushy—lesson learned. Toasting separately seals the buns and adds that crunch contrast against the tender corned beef. Multitasking by making the sauce while buns toast saves precious minutes, making this recipe ideal for busy cooks.

Variations & Adaptations

• Vegetarian Version: Swap corned beef for grilled portobello mushrooms or a thick slice of roasted beet for an earthy twist. Use vegan Swiss cheese and mayo to keep it plant-based.
• Spicy Kick: Add a dash of hot sauce to the Thousand Island or mix diced jalapeños into the slaw for some heat without overpowering the classic flavors.
• Gluten-Free Option: Use gluten-free slider buns or mini gluten-free bread rounds. The rest of the ingredients are naturally gluten-free, but double-check the sauerkraut and Worcestershire sauce labels to be safe.
• Cooking Method: Try baking the sliders in a preheated oven at 350°F (175°C) for about 10 minutes to melt cheese and warm through, then broil for a minute to crisp the tops if you prefer less stovetop time.

Personally, I once added caramelized onions to the layers for extra sweetness and texture—totally changed the game and earned rave reviews from my picky eaters!

Serving & Storage Suggestions

Serve these sliders hot and fresh off the stove for that unbeatable crisp and melty cheese. They pair beautifully with a side of crunchy dill pickles, crispy kettle chips, or a light cucumber salad to balance the richness.

Store any leftovers in an airtight container in the refrigerator for up to 2 days. To reheat, wrap them in foil and warm in a 350°F (175°C) oven for 10 minutes, or pop them in a skillet over low heat, covered, until heated through and cheese re-melted. Avoid microwaving if you can—it tends to make the buns soggy.

Flavors develop nicely if you let the sauce sit for a few hours before serving—it gets tangier and more vibrant. Just keep the sauce refrigerated and give it a quick stir before adding to the sliders.

Nutritional Information & Benefits

Each slider contains approximately 220 calories, with 12 grams of protein and 14 grams of fat, making it a satisfying snack or light meal. The corned beef provides iron and B vitamins, while Swiss cheese adds calcium and protein. The homemade Thousand Island sauce keeps added sugar and preservatives low compared to store-bought versions.

This recipe is naturally gluten-free if you swap the buns, and you can customize fat content by choosing lean corned beef or lighter cheese options. For those watching sodium, rinsing the corned beef lightly can help reduce saltiness without sacrificing flavor.

From a wellness perspective, this recipe balances indulgence with wholesomeness—comfort food that doesn’t feel like a guilty secret, just pure enjoyment.

Frequently Asked Questions

Can I make the Thousand Island sauce ahead of time?

Absolutely! The sauce actually tastes better if you make it a few hours ahead and chill it. Just stir before serving.

What can I use instead of corned beef?

Try pastrami, turkey pastrami, or even thinly sliced roast beef. For vegetarians, grilled mushrooms or roasted beets work well.

How do I keep the sliders from getting soggy?

Drain the sauerkraut well or use quick-pickled cabbage with minimal liquid. Toast the buns separately to create a barrier against moisture.

Can I freeze these sliders?

While you can freeze assembled sliders, the texture of the buns may change. It’s better to freeze the components separately and assemble fresh when ready.

What’s the best way to reheat leftovers?

Oven reheating wrapped in foil at 350°F (175°C) for about 10 minutes keeps the sliders crispy and melty. Avoid microwaving if possible.
