Dip sandwiches french are French Dip Sliders made with split slider buns, thin roast beef, provolone, caramelized onions, and a hot au jus for dipping, ready in 40 minutes total. This recipe serves 12 sliders and uses a 350°F oven for an easy, structured bake that keeps the buns soft and the cheese melted.
I am Alexia Michaels, a senior health and fitness researcher at XNutrion, so I pay close attention to recipe details, timing, and consistency when I test a dish like this. I measured this batch to fit a 9×13-inch baking dish and keep the sliders simple enough for game day, buffet service, or a fast family dinner.
French Dip Sliders deliver a soft bun, savory beef, and provolone that melts into the onion layer without turning soggy. The au jus stays separate for dipping, which helps each slider hold its structure while still tasting rich and warm.
When I tested this recipe, I kept the butter topping thin and even so the buns browned lightly instead of getting heavy. That detail matters when you want French Dip Sliders to travel well from oven to table.

Why does Dip Sandwiches French work so well for parties?
Dip sandwiches french works well for parties because French Dip Sliders are compact, fast to bake, and easy to serve with the au jus kept hot on the side. The recipe makes 12 sliders in about 40 minutes, which helps me plan a simple buffet without last-minute stress.
- It scales cleanly for a crowd. One 9×13-inch dish holds 12 sliders, so I can set up a full tray without extra pans. For heavier appetites, I plan 2 sliders per person and add a simple side.
- It stays practical during game day timing. The onions can cook while the broth warms, so the steps overlap efficiently. That makes French Dip Sliders easier to finish before kickoff or during halftime.
- It holds together better than a loose sandwich. The bun layer, roast beef, and provolone stack neatly in the baking dish. The melted butter topping also helps the tops brown and stay appealing on a buffet line.
- It reheats in a controlled way. The sliders can be warmed back up while the au jus is reheated separately. That keeps the bread from soaking through too early.
The ingredient balance matters because the caramelized onions add sweetness, while the Worcestershire and au jus mix add depth without overpowering the roast beef. I tested that contrast with a few different bun styles, and the soft rolls gave the best structure for French Dip Sliders.
What ingredients do you need for French Dip Sliders?
French Dip Sliders use 12 slider buns, roast beef, provolone, caramelized onions, and a simple au jus made from beef broth and gravy mix. The topping uses melted butter, Dijon mustard, Worcestershire sauce, onion powder, garlic powder, and optional sesame seeds for a finished top.

- 12 slider buns or Hawaiian sweet rolls, split horizontally
- 1 1/2 pounds thinly sliced roast beef
- 8 slices provolone cheese
- 1 large yellow onion, thinly sliced
- 2 tablespoons unsalted butter
- 1 tablespoon olive oil
- 1 teaspoon Worcestershire sauce
- 1 teaspoon garlic powder
- 1/2 teaspoon kosher salt
- 1/4 teaspoon black pepper
- 2 cups beef broth
- 1 tablespoon au jus gravy mix
- 2 tablespoons unsalted butter, melted
- 1 teaspoon Dijon mustard
- 1 teaspoon Worcestershire sauce
- 1 teaspoon onion powder
- 1/2 teaspoon garlic powder
- 1 tablespoon sesame seeds, optional
The roast beef and provolone do most of the heavy lifting here because they create the classic French dip flavor in each bite. The beef broth plus au jus gravy mix also matters, since it gives the sliders a dipping sauce that tastes intentional rather than thin.
How do you make French Dip Sliders step by step?
The method is straightforward: cook the onions, warm the au jus, layer everything in a baking dish, brush on the butter topping, and bake until the cheese melts. French Dip Sliders come together quickly because the skillet and saucepan work in parallel, which keeps the total cook time at 25 minutes.
Step 1 — Prep the oven and baking dish
Preheat the oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish so the bottoms release cleanly after baking.
Step 2 — Caramelize the onions
Heat 2 tablespoons butter and the olive oil in a skillet over medium heat. Add the sliced onion and cook for 8 to 10 minutes, stirring occasionally, until softened and lightly caramelized.

Step 3 — Season the onions
Stir in 1 teaspoon Worcestershire sauce, 1 teaspoon garlic powder, salt, and pepper. Cook for 1 minute more, then remove the skillet from the heat.
Step 4 — Warm the au jus
In a small saucepan, whisk together the beef broth and au jus gravy mix. Heat over medium heat until hot, then reduce the heat to low to keep warm.
Step 5 — Assemble the sliders
Place the bottom halves of the slider buns in the prepared baking dish. Layer half of the roast beef over the buns, then add the caramelized onions and provolone cheese. Top with the remaining roast beef and the bun tops.
Step 6 — Brush on the butter topping
In a small bowl, mix the melted butter, Dijon mustard, 1 teaspoon Worcestershire sauce, onion powder, and 1/2 teaspoon garlic powder. Brush or spoon the mixture evenly over the tops of the buns, then sprinkle with sesame seeds if using.

Step 7 — Bake and serve

Frequently Asked Questions About French Dip Sliders
Can I make French Dip Sliders ahead of time?
Yes, you can assemble French Dip Sliders ahead of time and bake them later. I recommend keeping the butter topping separate until just before baking so the buns stay tender instead of overly soft.
How many French Dip Sliders should I plan per person?
Plan on 2 sliders per person for most gatherings. If you are serving French Dip Sliders as the main meal, 3 per person is a safer amount for bigger appetites.
What is the best way to keep them warm for serving?
Keep French Dip Sliders covered with foil in a low oven for short periods. I also keep the au jus on low heat so the dipping sauce stays hot without reducing too far.
Can I reheat leftover French Dip Sliders?
Yes, reheat them covered in the oven until warm and heat the au jus separately. That method protects the bun texture better than microwaving everything together.
Are Hawaiian rolls a good choice for this recipe?
Yes, French Dip Sliders Hawaiian Rolls work very well because they are soft and slightly sweet. That texture balances the savory roast beef, cheese, and onions.
