1. 1
   Add butter and a splash of olive oil to a skillet over medium heat.
   ▶ ≈0:48
2. 2
   Slice the yellow onion thinly and add to the skillet. Cook for about 8 minutes until softened and lightly caramelized.
   ▶ ≈1:02
3. 3
   Turn off the heat and sprinkle garlic and herb seasoning over the warm onions to bloom the flavors.
   ▶ ≈3:32
4. 4
   Slice the Hawaiian rolls in half horizontally. Preheat the oven to 375°F.
   ▶ ≈1:45
5. 5
   Spread a small amount of yellow mustard on the bottom half of each roll, then layer with provolone cheese slices.
   ▶ ≈2:50
6. 6
   Layer the thinly sliced roast beef generously over the cheese, then scatter the caramelized onions on top.
   ▶ ≈3:40
7. 7
   Add another layer of cheese on top, then place the top half of the roll over it. The cheese acts like edible glue to hold everything together.
   ▶ ≈5:00
8. 8
   Melt the remaining butter and mix with a pinch of garlic and herb seasoning and a dash of Worcestershire sauce to make a butter topping.
   ▶ ≈5:19

    Bake in the 375°F oven covered with foil for 15 minutes.

    Remove the foil and bake for another 5 to 10 minutes until the tops are a beautiful golden brown and the cheese is fully melted with a crispy top.
    ▶ ≈5:58
12. 12
    While the sliders bake, prepare the au jus sauce: Mix 2 tbsp of au jus seasoning with 1¾ cups water, heat, and add a few dashes of Worcestershire sauce. Simmer for a few minutes until thickened. Alternatively, use 1½ cups beef broth with a pinch each of granulated garlic and onion, plus Worcestershire sauce, then thicken at the end with a cornstarch slurry (1 tsp cornstarch mixed with 1 tbsp water).
    ▶ ≈6:20
