03 - 12 slices provolone cheese
04 - 2 tablespoons unsalted butter, melted

13 - 1 tablespoon Worcestershire sauce
14 - 1 teaspoon soy sauce
15 - 1 teaspoon garlic powder
16 - Salt and freshly ground black pepper, to taste
# How To Make It:
01 - Preheat oven to 350°F. Line a 9x13-inch baking dish with parchment paper or lightly grease it.
02 - Melt 2 tablespoons butter in a skillet over medium heat. Add sliced onions and a pinch of salt. Cook, stirring occasionally, until deeply caramelized, about 12-15 minutes. Set aside.
03 - Slice the slider buns horizontally, keeping bottoms and tops connected. Place bottom half in the prepared baking dish.
04 - Layer half the cheese slices over the buns. Distribute roast beef evenly, then top with caramelized onions and remaining cheese. Place top half of buns over the cheese.
05 - In a small bowl, mix melted butter, Dijon mustard, Worcestershire sauce, and garlic powder. Brush evenly over tops of buns. Sprinkle with poppy seeds if desired.
06 - Cover dish with foil and bake for 15 minutes. Remove foil and bake another 5-7 minutes, until tops are golden and cheese is melted.
07 - In a saucepan, combine beef broth, Worcestershire sauce, soy sauce, and garlic powder. Bring to a simmer and cook for 5 minutes. Adjust seasoning with salt and pepper.
08 - Serve sliders warm with small bowls of au jus for dipping.
# Expert Tips:
01 -
- These sliders balance tender beef, sweet onions, and salty cheese in every bite
- The homemade au jus transforms them from ordinary sandwiches into something restaurant worthy
02 -
- Assembly matters because the bottom bun needs direct contact with the beef to prevent sogginess
- The foil step is crucial for melting the cheese without burning the bun tops
03 -
- Pat the roast beef gently with paper towels if it seems excessively wet
- Let the sliders rest for 3 minutes before cutting so the cheese sets slightly
