French Dip Sliders are made with tender roast beef, sweet caramelized onions, and melted provolone cheese tucked inside soft slider rolls. They’re baked until warm and golden, then served with savory au jus for dipping.
These are one of my favorite ways to turn a classic French dip sandwich into an easy meal for a crowd. The caramelized onions take a little extra time, but they add so much flavor with the roast beef, melted provolone, and warm au jus.
Why I Love French Dip Sliders
About the Ingredients ⭐
- Butter: Used to caramelize the onions and brush the tops of the rolls before baking.
- Onion: Slowly cooking the sliced onion brings out its sweetness and gives the sliders that classic French dip flavor.
- King’s Hawaiian Rolls: Soft, slightly sweet rolls that are the perfect size for sliders.
- Roast Beef: Thinly sliced deli roast beef keeps these sliders quick and easy to assemble.
- Provolone Cheese: Melts over the roast beef for a creamy, cheesy layer.

How To Make French Dip Sliders
Caramelize the onions:
- In a large skillet, melt 2 tablespoons of butter over medium heat.
- Add the sliced onions and sprinkle with salt.
- Cook the onions, stirring occasionally, for about 20-25 minutes or until golden brown and caramelized. Adjust the heat as necessary to prevent burning.
Assemble and bake the sliders:
- Preheat your oven to 350°F (175°C).
- Place the bottom halves of the slider rolls in a 9×13-inch baking dish.
- Evenly distribute the caramelized onions over the bottom half of the rolls.
- Layer the thinly sliced roast beef over the onions.
- Place a slice of provolone cheese on top of each portion of beef.
- Cover with the top halves of the slider rolls.
- Brush the tops of the rolls with the melted butter.
- Cover the baking dish with aluminum foil and bake in the oven for 15 minutes.
- Remove the foil and bake for an additional 5 minutes, or until the cheese is melted and the tops are golden brown.
Make the au jus:
- While the sliders are baking, prepare the au jus dipping sauce according to the packet instructions, typically by mixing the au jus mix with 2 cups of water.
- Add Worcestershire sauce and garlic powder to the prepared au jus, stirring to combine. Heat the mixture over medium heat until warmed through.
Serve:
- Cut the sliders apart and serve warm with the au jus on the side for dipping. Enjoy!
Tips I Found Helpful 💙
- Take your time with the onions. Cook them slowly until they’re soft and caramelized for the best flavor.
- Keep the rolls connected. Slice the whole sheet of rolls in half horizontally instead of separating each roll.
- Layer the roast beef evenly. This makes sure every slider gets plenty of meat and cheese.
- Brush the tops with melted butter. It helps the rolls bake up soft with a lightly golden top.
