Method
 

Step 1:
  1. Preheat the oven to 180°C (350°F). Lightly grease a baking dish and set it aside.
Step 2:
  1. Melt 1 tablespoon of butter in a skillet over medium heat. Add the sliced onion and cook for 5–7 minutes until soft, golden, and lightly caramelized. Remove from heat.
Step 3:
  1. Using a sharp knife, slice the sweet rolls horizontally as one block, keeping the tops and bottoms connected.
Step 4:
  1. Place the bottom half of the rolls into the prepared baking dish. Layer the deli roast beef evenly over the rolls.
Step 5:
  1. Spread the cooked onions evenly over the roast beef, then sprinkle with black pepper and kosher salt.
Step 6:
  1. Place the provolone cheese slices over the beef and onions, covering the entire surface.
Step 7:
  1. Place the top half of the rolls over the cheese layer and gently press down.
Step 8:
  1. In a small saucepan, melt the remaining butter over low heat. Stir in the dried onion soup mix and chopped fresh thyme.
Step 9:
  1. Using a pastry brush, generously brush the butter mixture over the tops of the rolls, making sure it seeps into the edges.
Step 10:
  1. Cover the baking dish loosely with foil and bake for 15 minutes.
Step 11:
  1. Remove the foil and bake for an additional 5–7 minutes, or until the tops are golden brown and the cheese is fully melted.
Step 12:
  1. While the sliders bake, prepare the au jus by bringing the water to a gentle boil in a small saucepan. Whisk in the au jus gravy mix and simmer for 2–3 minutes until smooth.
Step 13:
  1. Remove the sliders from the oven and let them rest for 3–5 minutes. Slice into individual sliders and garnish with fresh parsley.
Step 14:
  1. Serve warm with the au jus on the side for dipping.
