Ingredients
- 42 g (3 tbsp) unsalted butter

- 2 g (2 tsp) fresh thyme, minced
- 1.5 g (¼ tsp) kosher salt
- 0.5 g (¼ tsp) black pepper
- 12 sweet rolls
- 10 slices provolone cheese
- 400 g (14 oz) sliced deli roast beef
- 115 g (½ cup) unsalted butter, melted
- 12 g (1½ tbsp) dried onion soup mix
- 1 packet au jus gravy mix
- 720 ml (3 cups) water
- Fresh chopped parsley (optional garnish)
How to Make Them
1. Caramelize the Onions:
In a large skillet, melt 3 tablespoons butter over medium heat. Add sliced onions and stir to coat. Cook for 12–15 minutes, stirring occasionally, until soft and golden. Stir in thyme, salt, and pepper. Remove from heat.
2. Build the Sliders:
Preheat your oven to 350°F (175°C). Slice the sweet rolls horizontally without separating them. Place the bottom half into a greased 11×7-inch baking dish.
Layer with half of the provolone cheese, followed by all the roast beef, the caramelized onions, and the rest of the cheese. Place the top half of the rolls over everything.
3. Brush with Butter:
Mix the melted butter with the dried onion soup mix. Brush generously over the tops of the rolls.
4. Bake:
Cover loosely with foil and bake for 25 minutes. Remove foil and bake for 5 more minutes until golden and melty.
5. Make the Au Jus:
While sliders bake, prepare the au jus by whisking the gravy mix into 3 cups of water in a saucepan. Heat according to package directions until warm.
6. Serve:
Slice the sliders, garnish with parsley if you like, and serve with warm au jus for dipping.
Tips for Slider Success
- Use a serrated knife to slice the rolls neatly.
- Make ahead? You can assemble the sliders earlier in the day and bake when ready.
- Too much liquid? Drain the roast beef slightly if it’s overly juicy to avoid soggy bottoms.
- Feeding a crowd? Double the recipe and use a large sheet pan.

They’re just as good reheated the next day (if they even last that long).
What to Serve with French Dip Sliders
- Crispy potato wedges or fries
- Pickles for a little bite
- Caesar salad to balance the richness
- Sparkling lemonade or light beer for sipping
How to Store Leftovers

- Keep au jus in a separate container and reheat on the stove or in the microwave.
FAQs About French Dip Sliders
Can I use a different cheese?
Absolutely. Swiss or mozzarella work well if provolone isn’t your favorite.
Can I make this ahead of time?
Yes—assemble ahead and bake when ready to serve.
Is this freezer-friendly?
Best fresh, but you can freeze baked sliders. Just wrap tightly and reheat covered with foil.
