Ingredients

12 mini brioche buns (or your favorite slider rolls)
12 oz thin‑sliced corned beef (about 340 g)
6 oz Swiss cheese, sliced into quarters (≈170 g)
1 cup sauerkraut, drained and rinsed
¼ cup Russian dressing (store‑bought or homemade)
2 tbsp unsalted butter, melted
1 tsp smoked paprika (optional, for extra depth)
Salt & pepper to taste

Directions

Preheat the oven to 425°F (220°C). Line a large baking sheet with parchment paper or a silicone mat.
Prep the buns: Slice each brioche bun in half horizontally. Brush the cut sides lightly with the melted butter; this will create a glossy, golden crust.
Season the butter: Stir smoked paprika, a pinch of salt, and freshly ground black pepper into the remaining butter. Brush this spiced butter over the outer faces of the buns for extra flavor.
Assemble the base: Place the bottom halves of the buns, butter‑side up, on the prepared baking sheet.
Layer the corned beef: Distribute the thin‑sliced corned beef evenly across each bun base, ensuring each slider gets about 1 oz of meat.
Add sauerkraut: Spoon a tablespoon of drained sauerkraut over the meat on each slider. Pat gently so it stays in place during baking.
Drizzle Russian dressing: Lightly drizzle ½ teaspoon of dressing over each sauerkraut mound. This adds the classic tang without making the buns soggy.
Top with Swiss cheese: Place a quarter‑slice of Swiss cheese on each slider. The cheese will melt and create that signature gooey layer.
Cover with top bun: Lay the top halves of the buns, butter‑side down, over the cheese.
Bake for 8‑10 minutes, or until the buns turn a deep golden‑brown and the cheese is fully melted. For extra crispness, switch to the broiler for the last 1‑2 minutes—watch closely!
Rest & serve: Remove from the oven and let the sliders rest for 2 minutes. This allows the cheese to set slightly, making them easier to pick up.
Plate the sliders on a serving platter, garnish with a sprinkle of fresh chives or dill if desired, and serve warm.

Pro Tips & Tricks

Use a wire rack on the baking sheet to allow hot air to circulate around the sliders, giving an even crisp.
Dry the sauerkraut thoroughly with a clean kitchen towel; excess moisture can make the buns soggy.
Thin‑slice the corned beef or even give it a quick flash‑freeze to make slicing easier and more uniform.
Make a quick Russian dressing by whisking together mayo, ketchup, horseradish, Worcestershire sauce, and a dash of hot sauce.
For extra crunch, sprinkle a thin layer of panko breadcrumbs on the buttered side before baking.

Variations & Substitutions

Protein Swaps

• Smoked turkey for a lighter option.
• Roasted tempeh (marinated in soy‑ginger) for a vegetarian twist.
• Pulled pork with a light BBQ glaze for a Southern spin.

Bread Alternatives

• Gluten‑free mini rolls or lettuce cups for a low‑carb version.
• English muffin halves for a heartier bite.
• Bagel bites for a chewier texture.

Cheese & Sauce Tweaks

• Swap Swiss for Gruyère for a nuttier melt.
• Use a tangy spicy mustard instead of Russian dressing for a sharper bite.
• Add a thin slice of pickles for extra crunch.

Storage & Reheating

These sliders keep well in the refrigerator for up to 2 days. Store them in an airtight container, separating the top buns with parchment to prevent sogginess. To reheat, place the sliders on a baking sheet and warm at 350°F (175°C) for 5‑7 minutes, or pop them under a brief broiler blast for a freshly crisp finish. For a quick microwave fix, wrap each slider in a damp paper towel and heat for 30‑45 seconds—though the texture will be softer than oven‑reheated.
