# What You Need:

→ For the Sliders

01 - 12 slider buns or Hawaiian rolls
02 - 1 lb thinly sliced roast beef
03 - 12 slices provolone cheese
04 - 2 tablespoons unsalted butter, melted
05 - 1 tablespoon Dijon mustard
06 - 1 tablespoon Worcestershire sauce
07 - 1 teaspoon garlic powder
08 - 1 tablespoon poppy seeds (optional)

09 - 2 tablespoons unsalted butter
10 - 1 large yellow onion, thinly sliced
11 - Pinch of salt

→ For the Au Jus

12 - 2 cups beef broth, low sodium
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:

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, keeping the bottoms and tops connected. Place the bottom half in the 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, combine beef broth, Worcestershire sauce, soy sauce, and garlic powder in a saucepan. 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 -
  • The melted cheese and tender beef create that perfect pull apart quality that makes sliders irresistible
  • They come together in under an hour but taste like something from a restaurant
  • The au jus dipping sauce transforms each bite into something incredibly rich and satisfying
02 -
  • Dont rush the onions, their natural sweetness is what balances the salty beef and cheese
  • Let the sliders rest for 3 minutes after baking so the cheese sets slightly and doesn't slide right off when you cut them
  • The aujus should be warm but not boiling hot when served or it'll cool down your sliders too fast
03 -
  • If your slider buns are especially tall, slice a bit off the top half so they fit comfortably in guests mouths
  • Warm your beef broth in the microwave for 30 seconds before making the au jus for faster results
  • Line your baking dish with parchment paper that hangs over the sides, then use it as handles to lift the whole slab out for easier cutting
