Step-by-Step Instructions for BEST French Dip Sliders
  1. Melt 3 tablespoons of unsalted butter in a large skillet over medium heat. Add thinly sliced medium onions and cook for about 8-10 minutes until softened and golden brown. Stir in fresh thyme, kosher salt, and black pepper, then set aside.
  2. Slice sweet rolls horizontally while keeping halves together, creating a sturdy base for the sliders. Set aside on a baking sheet.
  3. Layer sautéed onion mixture on bottom halves of sliced rolls, add provolone cheese, and top with deli roast beef. Cap with top halves of the rolls.
  4. In a small saucepan, melt 0.5 cup of unsalted butter over medium heat. Whisk in dried onion soup mix and au jus gravy mix, then add 3 cups of water. Simmer for 2-3 minutes until thickened.
  5. Pour au jus into a shallow dish for dipping. Serve sliders warm dipped in au jus just before enjoying.
