Method
Sliders
- Preheat the oven to 375°F. Brush a 9 x 13-inch baking dish with a little melted butter.
- Heat the olive oil in a large skillet over medium heat. Cook the onion for 5 minutes, stirring occasionally, until softened with golden edges.
- Slice the rolls horizontally through the center without separating them. Place the bottom slab in the baking dish.
- Layer half the provolone, all the roast beef, the onions, and the remaining provolone over the rolls. Add the top slab.
- Stir the remaining melted butter with 1 teaspoon Worcestershire sauce, garlic powder, and poppy seeds. Brush the mixture over the roll tops.
Au Jus and Finish
- Cover the baking dish with foil and bake for 10 minutes.
- While the sliders bake, combine the beef broth, remaining 2 teaspoons Worcestershire sauce, soy sauce, and black pepper in a saucepan. Simmer for 5 minutes.
- Uncover the sliders and bake for 5 minutes, until the cheese melts and the tops are golden. Let stand for 2 minutes, slice, and serve with warm au jus.
Notes
Refrigerate leftover sliders and au jus separately for up to 3 days. Reheat the sliders uncovered at 350°F until hot so the roll tops regain some texture. Assemble the filling up to 8 hours ahead, but wait to add the butter topping until baking. Baked sliders can be frozen for 1 month, although the rolls will be softer after thawing.
