Main Ingredients

  • 12 buns Hawaiian or regular slider buns
  • ½ Cup Butter divided
  • 1 Onion yellow, medium, thinly sliced
  • 4 Sprigs Thyme, fresh divided
  • 1 teaspoon Water
  • Kosher Salt
  • Black Pepper freshly ground
  • 3 Tablespoon Dijon mustard Stone Ground
  • ½ Pound Deli Roast Beef
  • 9-12 Slices Provolone Cheese
  • 1 teaspoon Worcestershire Sauce
  • 2 Tablespoons Mayonnaise
  • 1 teaspoon Dijon Mustard
  • 1 teaspoon Toasted Sesame Seeds
  • 1 Tablespoon Parsley freshly chopped

For the Au Jus

  • 1 Clove Garlic minced
  • 1 Cup Beef Broth low sodium
  • 1 Tablespoon Worcestershire Sauce

Instructions
 

Preparation

  • Preheat oven to 350° and grease a 9"-x-13" baking sheet with cooking spray. Place the bottom half of the rolls in the bottom of the pan.
  • In a large skillet over medium heat, melt 2 tablespoons of butter. Add onion and 2 sprigs thyme, water and season with salt and pepper.
  • Cook, stirring occasionally, until the onions begin to soften and turn slightly golden. Continue cooking, stirring occasionally, until onions are caramelized, about 20 to 25 minutes. Remove from heat.
  • Spread an even layer of mustard onto bread. Top with a layer of roast beef and a layer of provolone. Top with caramelized onions, then cover with the tops of the rolls.
  • Melt all but one tablespoon of the remaining butter and mix with Worcestershire, mayonnaise, dijon mustard, and the toasted sesame seeds. Spread over the buns. Cover with foil. Bake until golden and cooked through, about 20-30 minutes. Sprinkle the parsley on top after baking.
  • Meanwhile, melt remaining 1 tablespoon butter in a medium skillet over medium heat. Stir in garlic and cook until fragrant. Add beef stock, Worcestershire sauce and remaining 2 sprigs thyme, stripped from stem. Season with salt and pepper. Simmer for 10 minutes until reduced slightly.
  • Serve squares with au jus on the side for dipping.

Notes

Toast sesame seeds in a pan over medium heat, stirring often until they start to turn golden. To reheat, place sliders on a baking sheet, cover with foil and reheat in a 350 degree oven for 12 minutes.
