Ingredients
- ⅓ cup mayonnaise
- 1 ½ tablespoons ketchup
- 1 ½ teaspoons horseradish
- ½ teaspoon Worcestershire sauce
- Salt and pepper, to taste
- 1 package slider buns (12 count)
- ½ pound sliced corned beef, freshly cut deli version preferred
- 1 cup sauerkraut, drained
- 12 slices Swiss cheese (about 8 ounces)
- ¼ cup (½ stick) butter, melted
- 1 tablespoon Dijon mustard
- ½ teaspoon garlic powder
- 1 tablespoon parmesan cheese
- 2 teaspoons poppy seeds
- Parmesan, to sprinkle over sandwiches, if desired
Instructions
- Step 1: Preheat the oven to 350ºF (175ºC).
- Step 2: Whisk together mayonnaise, ketchup, horseradish, Worcestershire sauce, salt, and pepper to make the Russian dressing. Set aside.
- Step 3: Slice the slider buns in half horizontally. Place the bottom halves in an oven-safe dish without separating them.
- Step 4: Spread the Russian dressing evenly over the bottom buns. Layer with half the corned beef slices, half the Swiss cheese, then the sauerkraut. Top with the remaining corned beef and cheese. Place the top buns over the stack.
- Step 5: Combine melted butter, Dijon mustard, garlic powder, parmesan cheese, and poppy seeds. Drizzle this mixture evenly over the top buns. Sprinkle extra parmesan if desired.
- Step 6: Cover the dish with foil and bake for 30 minutes, or until the cheese is melted and the sliders are thoroughly heated.
- Step 7: Remove the foil and broil the sliders for about one minute to achieve a golden top, if you like.
- Step 8: Cut the sliders apart and serve warm.
Tips & Variations
- Use freshly sliced corned beef from the deli for the best texture and flavor.
- Drain the sauerkraut well to prevent soggy sliders.
- Try adding a few thin slices of pickles inside for extra tang.
- Substitute Swiss cheese with provolone for a milder taste.
- For a spicier kick, add a dash of hot sauce to the Russian dressing.
Storage
Store any leftover sliders in an airtight container in the refrigerator for up to 3 days. Reheat covered in a low oven (around 300ºF) until warmed through to keep the bread from drying out. Avoid microwaving if possible, as it can make the buns soggy.
