Ingredients

Scale

Slider Ingredients

  • 3 tablespoons unsalted butter
  • 1 medium onion, thinly sliced
  • 2 teaspoons fresh thyme, minced
  • 1/4 teaspoon kosher salt
  • 1/4 teaspoon black pepper
  • 12 sweet rolls
  • 10 slices provolone cheese
  • 14 ounces sliced deli roast beef

Topping and Sauce Ingredients

  • 1/2 cup unsalted butter, melted
  • 1 & 1/2 tablespoons dried onion soup mix
  • 1 packet au jus gravy mix
  • 3 cups water
  • Fresh chopped parsley for garnish (optional)

Instructions

  1. Caramelize the onions: In a large skillet over medium heat, melt the butter. Add the sliced onions and coat them in the butter. Cook, stirring occasionally, for 12-15 minutes until the onions are soft and browned but not burnt. Stir in the minced thyme, kosher salt, and black pepper. Remove from heat and set aside.
  2. Preheat the oven: Set your oven to 350°F (175°C) to prepare for baking the sliders.
  3. Prepare the rolls: Without separating the rolls, slice them horizontally with a large knife to separate the tops from the bottoms. Place the bottom halves, cut side up, in an 11×7-inch baking dish.
  4. Assemble the sliders: Layer half of the provolone cheese over the bottom rolls. Next, add the sliced deli roast beef, followed by a generous spread of the caramelized onions. Top with the remaining cheese slices, then place the roll tops over the cheese.
  5. Make the butter topping: In a small bowl, combine the melted butter and dried onion soup mix. Brush this mixture evenly over the tops of the rolls, or pour gently to cover them thoroughly.
  6. Bake the sliders: Loosely cover the baking dish with foil, avoiding contact with the roll tops. Bake for 25 minutes. Then remove the foil and continue baking for an additional 5 minutes to brown the tops.
  7. Prepare the au jus: While the sliders bake, prepare the au jus gravy mix according to the package instructions using 3 cups of water.
  8. Serve: Garnish the baked sliders with fresh chopped parsley if desired, and serve warm with the au jus on the side for dipping. Enjoy your flavorful French Dip Sliders!

Notes

  • Use sweet rolls for a slightly sweet contrast to the savory roast beef and cheese.
  • Be careful not to burn the onions while caramelizing for best flavor.
  • Loosely covering the sliders with foil prevents the tops from burning while allowing even baking.
  • The au jus gravy mix enhances the dipping experience but can be made from scratch if preferred.
  • These sliders are great for parties and can be easily doubled or halved depending on the number of guests.
