1. Prepare the beef: Choose freshly sliced roast beef from the deli for convenience or slow-cook a roast, such as chuck or top round, with beef consommé, garlic, onion, and Worcestershire sauce for around 7.5 hours until tender.

2. Caramelize the onions: Thinly slice onions and cook them slowly in butter over low heat until golden brown. This process takes 30-45 minutes.

3. Slice the rolls: Split the King’s Hawaiian Rolls in half while keeping the tops and bottoms intact.

4. Assemble the sliders: Begin layering the bottom halves of the rolls with a slice of provolone cheese, followed by the roast beef, caramelized onions, and another layer of cheese.

5. Replace the top halves: Place the top portions of the rolls back on to complete the assembly.

6. Prepare the garlic butter: Melt butter and mix it with minced garlic, parsley, and salt. Brush this over the tops of the sliders evenly.

7. Preheat the oven: Set the oven to 350°F (175°C) and prepare a baking dish.

8. Bake the sliders: Place the sliders in the baking dish, cover with aluminum foil, and bake for 15-20 minutes. Remove the foil and bake for an additional 5-10 minutes until the tops are golden and the cheese has melted.

9. Prepare the Au Jus: Mix the Au Jus packet with water or beef consommé and whisk until combined. Bring the mixture to a boil for a flavorful dipping sauce.

10. Serve and enjoy: Serve the sliders warm alongside the prepared Au Jus for dipping, and pair with sides like French fries or potato chips.
