Kitchen Tools You’ll Need

Step-by-Step Beginner-Friendly Instructions

1. Preheat the oven to 350°F (175°C). Lightly grease your baking dish.
2. Slice the slider buns in half horizontally, keeping the tops and bottoms connected as a slab. Place the bottom half in the baking dish.
3. Mix the sauce by stirring the Russian dressing and horseradish together in a small bowl. Spread evenly over the buns.
4. Layer the fillings: Add corned beef, Swiss cheese, and sauerkraut in even layers. Finish with another light layer of Swiss cheese.
5. Add the bun tops, pressing gently so everything holds together.
6. Make the topping: Stir melted butter, garlic, and caraway seeds. Brush generously over the tops.
7. Bake uncovered for 18–20 minutes, until the cheese is melted and the tops are golden and glossy.
8. Cool slightly, slice, and serve warm

Multitasking tip: While the sliders bake, prep a simple salad or chips for serving.

Pro Tips

• Make ahead: Assemble up to 8 hours in advance, cover tightly, and bake when ready.
• Extra crispy tops: Loosely tent with foil for 10 minutes, then uncover to finish baking.
• No sauerkraut? Swap with caramelized onions for a milder flavor.
• Serving idea: Pair with pickles, kettle chips, or a simple coleslaw.
