Sliders are the perfect snack to fit in your hand, and trust me – you’ll have to stop yourself from eating the whole tray. Just be sure to grab a napkin because these flavors just can’t be contained!
Typically, French Dip sandwiches are made by slow cooking roast beef and using the drippings from the meat to create the au jus. Our recipe opts for roast beef right from the deli and is topped with a seasoned salt mustard sauce for an extra touch. This French Dip Sliders recipe might be quick and simple, but it certainly doesn’t skimp out on any of the classic flavors!

How To Make French Dip Sliders
For the Sliders:
- 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 x 13-inch baking dish.
- Lay the cheese slices over the buns, then top with the sliced roast beef. Add the onions, and place the tops of the buns back onto the sliders. Set aside.
For the Mustard Sauce:
- 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.
- Bake uncovered for 10 to 15 minutes until the cheese is melted and 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!
Tips and Variations
- These French Dip Sliders work great with leftover pot roast for a simple and time saving alternative.
- Add a little brown sugar to the mustard sauce for a sweet and savory flavor.
- Change up the type of cheese like swiss or gouda, or a yellow or stone ground mustard to combine and create new flavors.
- Add a pickle for a fun crunch!
Storage and Reheating
Refrigerator: Store these French Dip Sliders in a sealed container for up to 2 days in the fridge.
Reheating: When reheating, wrap the sandwich(es) in foil and place on the top oven rack. Heat for about 7-10 minutes until the cheese has melted and sandwiches are warmed through.

Looks really good. I made the sauce first to see how it would taste before doing full recipe and found the sauce to be too buttery. Would it taste differently poured over sliders and baked?

Hi Sandra!
Thanks so much! The sauce is very rich and buttery by itself, but it mixes well with the sliders when they're baked together. The butter flavor is toned down since it soaks into the buns. Another option is to reduce the butter some or even add some brown sugar in place of the mustard for a sweet and savory dish instead. Hope you have a wonderful weekend! :)

I’m planning on trying this recipe for the sliders, however, I couldn’t find any info on the au jus. Does it need to be purchased or is there a recipe to make it from scratch? Thanks
