French Dip Sliders

Servings: 12 servings
Author: This Worthey Life

Ingredients

  • 12 slider buns
  • 1 stick softened unsalted butter
  • 1/2 tbsp freshly cracked black peppercorns
  • 24 mini slices of swiss cheese
  • 12 mini Mozzarella provolone, or fontina slices
  • 1 large yellow or sweet onion
  • 2 tbsp of unsalted butter
  • 2 tbsp of extra virgin olive oil
  • your favorite pickles for serving

Instructions

  • Preheat oven to 350°.
    Make the Au Jus (see directions below).
    Make the Horseradish Sauce (see directions below).
    Make the black pepper butter: Add one stick of softened unsalted butter to a bowl. Add a half tablespoon of freshly cracked black peppercorns. 
    Place the bottom of the slider buns on a cooking sheet and slather each one with a healthy dollop of black pepper butter.
    Set a large skillet on the stovetop over medium heat, add a tablespoon of butter and a tablespoon of extra virgin olive oil; when the oil is hot, toast the buns until the edges are golden brown. Remove the buns and repeat the process with the top buns. Set aside. 
    Arrange the toasted bun bottoms on a sheet pan and a tablespoon of the horseradish sauce to each bun. Add a slice of Swiss and a slice of Provolone cheese.
    Add grilled onions and a generous amount of roast beast, then top with two more slices of cheese. *Do not add the top buns yet. Place the sliders into the preheated oven for 12-14 minutes. Slide the rack out and add the top buns. Cover the sliders with a length of aluminum foil and slide them back into the oven and back for an additional 2-3 minutes. 

Notes

Horseradish Sauce Recipe
1/2 cup sour cream
1/3 cup horseradish sauce
1 tbsp pickle juice
1/2 tsp Worcestershire sauce
pinch of freshly cracked black peppercorns
pinch of sea salt optional
Directions:
Mix well, and set aside or place the bowl inside the fridge until you are ready to make the sliders. You can make the Horseradish sauce ahead of time. 
Au Jus Recipe
2 cups beef stock or broth
2 -3 tbsp of french onion soup mix
1 tbsp of Worcestershire sauce
1 tbsp of extra virgin olive oil
Directions:
Place a small saucepan over low heat and add the beef stock or broth, French onion mix, Worcestershire sauce, and extra virgin olive oil; stir until the mixture is well combined.
When the mixture begins to boil, remove the saucepan from heat, cover with a tight-fitting lid, and set it aside until you are ready to serve the sliders. 
How to make your own Seasame Seed Sliders

If you can't find sesame seed or onion roll sliders make your own, here's how. Combine 3 tablespoons of unsalted butter with a single tablespoon of honey into a small bowl—and microwave for one minute.
Brush the tops of the buns with the melted butter and honey mixture. Top buns with either sesame seeds or dried onions, or both! 
Serve immediately with the au jus and pickles on the side.
