Ingredients

For the Sliders:

12 Hawaiian rolls
500g thinly sliced roast beef (deli-style or homemade)
200g provolone cheese, sliced
1 small onion (100g), thinly sliced
2 tablespoons unsalted butter (30g)
1 tablespoon Worcestershire sauce (15ml)
1 teaspoon Dijon mustard (5g)
½ teaspoon garlic powder (1g)
½ teaspoon dried thyme (1g)
½ teaspoon salt
¼ teaspoon black pepper

For the Au Jus (Dipping Sauce):

500ml beef broth (low sodium)
1 teaspoon Worcestershire sauce (5ml)
½ teaspoon garlic powder (1g)
½ teaspoon onion powder (1g)
¼ teaspoon black pepper
1 teaspoon cornstarch mixed with 2 teaspoons water (optional, for thickening)

For the Buttery Topping:

3 tablespoons butter (45g), melted
1 teaspoon Worcestershire sauce (5ml)
½ teaspoon garlic powder (1g)
½ teaspoon dried parsley (1g)
1 teaspoon sesame seeds (optional, for garnish)

Instructions

Step 1: Preheat & Prep

Preheat your oven to 180°C (350°F).
Lightly grease a 9×13-inch baking dish or line it with parchment paper.

Step 2: Caramelize the Onions

In a skillet over medium heat, melt 2 tablespoons butter.
Add the thinly sliced onions and cook for 8–10 minutes, stirring occasionally, until they become golden and caramelized.
Stir in Worcestershire sauce, Dijon mustard, garlic powder, thyme, salt, and pepper. Remove from heat.

Step 3: Assemble the Sliders

Slice the Hawaiian rolls in half horizontally, keeping them connected. Place the bottom half in the prepared baking dish.
Layer with half the provolone cheese, followed by the roast beef, then the caramelized onions, and finally the remaining cheese slices.
Place the top half of the rolls over the filling.

Step 4: Make the Buttery Topping

In a small bowl, mix the melted butter, Worcestershire sauce, garlic powder, and parsley.
Brush the mixture evenly over the tops of the rolls.
Sprinkle with sesame seeds (optional).

Step 5: Bake the Sliders

Cover the dish with foil and bake for 15 minutes.
Remove the foil and bake for another 5 minutes, or until the tops are golden brown and slightly crispy.

Step 6: Prepare the Au Jus

In a saucepan over medium heat, combine beef broth, Worcestershire sauce, garlic powder, onion powder, and black pepper.
Bring to a gentle simmer for 5 minutes.
If you prefer a slightly thicker sauce, stir in the cornstarch slurry and cook for another 1–2 minutes, until slightly thickened.

Step 7: Serve & Enjoy!

Remove the sliders from the oven and let them cool slightly.
Cut them apart and serve warm with the au jus dipping sauce on the side!

Tips & Tricks for the Best French Dip Sliders

✨ Use high-quality roast beef – Deli-style roast beef works great, but for even better flavor, use leftover homemade roast beef!

✨ Don’t skip the caramelized onions – They add a sweet, savory depth that elevates the sliders.

✨ Make them ahead – Assemble the sliders a few hours before baking and keep them in the fridge. When ready, just pop them in the oven!

✨ Toast the bottom layer – If you like a crispier bun, lightly toast the bottom half before assembling the sliders.

✨ Serve with extra cheese – Melted Swiss cheese or Gruyère can be mixed with provolone for even more gooey goodness.
