This is a recipe I don’t make often enough. These French dip sliders are a favorite in my house. I use a package of slider rolls, some roast beef deli meat, slices of provolone cheese, onions, and a tangy Dijon mustard sauce to top them off.

They’re really easy to assemble and bake in about 15 to 20 minutes. I can have a batch on the table in less than 30 minutes from start to finish, which is great when you have a hungry family to feed.

If you love sliders, don’t forget our pizza sliders. They also make a great appetizer or main dish. We also have a fun pancake slider recipe that is perfect for breakfast.

Kim’s Tips for Great French Dip Sliders

• A side of au jus: I like to serve these sliders with a side of au jus. Usually, I grab a packet and whisk it with some water to keep things really easy.
• Be careful of the saltiness: If you are sensitive to salt, consider omitting the seasoned salt or skipping the au jus.
• Slider rolls: I’ve made these on plain slider rolls and Hawaiian slider rolls. The Hawaiian rolls add a bit of sweetness. Both work great, so use whichever one you like best.

How to make French dip sliders step-by-step

Preheat the oven to 350°F.

Leave the slider buns intact and slice them in half lengthwise. Place the bottom half of the buns into a 9×13-inch baking dish.

Lay the cheese slices over the buns, then top with the sliced onions and roast beef. Place the tops of the buns back onto the sliders. Set aside.

In a small saucepan over low heat, melt the butter. Stir in the Worcestershire sauce, mustard, garlic powder, onion powder, and seasoned salt.

Pour the mixture over the sliders.

Cover the baking dish loosely with foil and bake for 10 to 15 minutes, until the cheese is melted and the sliders are heated through. Remove the foil and bake for another 5 minutes, or until the tops are golden brown.

Use a sharp knife to separate the sliders. Serve hot with a side of au jus. Either homemade or store bought works great!

• In a small saucepan over low heat, melt the butter. Stir in the Worcestershire sauce, Dijon mustard, garlic powder, onion powder, and seasoned salt.
  ½ cup unsalted butter

  1 tablespoon Worcestershire sauce

  1 teaspoon Dijon mustard

  ½ teaspoon garlic powder

  ¼ teaspoon onion powder

  ¼ teaspoon seasoned salt
• Pour the butter mixture evenly over the tops of the sliders.
• Cover the baking dish loosely with foil and bake for 10 to 15 minutes, until the cheese is melted and the sliders are heated through. Remove the foil and bake for another 5 minutes, or until the tops are golden brown.
• Use a sharp, serrated knife to separate the sliders. Serve hot with au jus for dipping.

Notes

1. Butter topping: The butter topping is meant to be poured over the sliders and baked. It isn’t used as a dipping sauce.
2. Au jus for dipping: The au jus in the photos is store-bought. A packet, jarred au jus, or homemade au jus all work.
3. Make a foil tent: If the tops start browning too quickly before the cheese melts, cover the sliders loosely with foil and move the pan to a lower oven rack.
4. How to make ahead: To make these ahead, assemble the sliders through the meat and cheese layer, cover, and refrigerate. Wait to add the butter topping until right before baking so the buns don’t get soggy. If baking straight from the fridge, add 5 to 7 extra minutes as needed.
5. Storage: Store leftover sliders in an airtight container in the refrigerator. Reheat them in a 300°F to 350°F oven, covered with foil, for 10 to 15 minutes or until warmed through. An air fryer also works at 350°F for 4 to 5 minutes. I’d skip the microwave since it can make the buns soft and the roast beef rubbery.
