# How to make it:
01 - Preheat the oven to 350°F. Line a 9x13-inch baking dish with parchment paper or lightly grease it.
02 - In a skillet over medium heat, melt 2 tablespoons butter. 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 while keeping the bottoms and tops connected. Place the bottom half in the prepared baking dish.
04 - Layer half the cheese slices over the buns. Evenly distribute the roast beef, then top with caramelized onions and remaining cheese. Place the top half of the buns over the cheese.
05 - In a small bowl, mix 2 tablespoons melted butter, Dijon mustard, Worcestershire sauce, and garlic powder. Brush evenly over the tops of the buns. Sprinkle with poppy seeds if desired.
06 - Cover the 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 - While sliders bake, prepare the au jus. 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.
