Description

These Roast Beef Sliders are a delicious and easy-to-make appetizer or meal option, featuring thinly sliced roast beef layered on soft slider buns with melted Swiss or provolone cheese, caramelized onions, and a flavorful horseradish-beef broth drizzle. Perfect for parties or casual gatherings, these sliders bake quickly in the oven until warm and gooey.


Ingredients

Scale

Sliders

  • 1 lb thinly sliced roast beef
  • 12 soft slider buns
  • 8 oz Swiss or provolone cheese, sliced
  • 1 cup caramelized onions (about 2 medium onions)
  • 1/2 cup beef broth
  • 2 tbsp horseradish sauce


Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C) to prepare for baking the sliders evenly.
  2. Prepare Buns: Slice the slider buns in half horizontally. Arrange the bottom halves on a baking sheet lined with parchment paper to prevent sticking and ensure easy cleanup.
  3. Layer Roast Beef: Place a generous amount of thinly sliced roast beef on the bottom half of each bun, providing a hearty base for the sliders.
  4. Add Cheese and Onions: Top the roast beef with slices of Swiss or provolone cheese and then add a layer of caramelized onions for sweetness and depth of flavor.
  5. Mix Sauce and Drizzle: In a small bowl, combine beef broth and horseradish sauce. Drizzle this mixture evenly over the layered sliders to add moisture and a spicy kick.
  6. Assemble and Bake: Cover each slider with the top half of the buns. Bake in the preheated oven for 15-20 minutes, or until the sliders are heated through and the cheese has melted to perfection.

Notes

  • You can caramelize onions ahead of time and store them in the refrigerator for convenient assembly.
  • Use your favorite cheese variety if Swiss or provolone aren’t available.
  • For extra flavor, add a touch of garlic powder or Worcestershire sauce to the beef broth mixture.
  • Serve with pickle slices or additional horseradish sauce on the side for dipping.
  • To keep sliders warm before serving, cover them loosely with foil.
