French Dip Sliders

These French Dip Sliders are cheesy, savory, and perfect for dipping. Just layer and bake, and your party sandwiches are ready in no time!

These French Dip Sliders take everything you love about a classic French dip sandwich and turn it into an easy pan of bite-sized sandwiches. Sweet Hawaiian rolls are stuffed with deli roast beef, melty provolone, and crispy fried onions, then brushed with a garlicky butter and served with warm au jus for dipping. They are perfect for game day, parties, and busy weeknights, and they feed a crowd with very little effort.

Why This Recipe Works

Everything is assembled on the whole slab of rolls at once, so there is no building sandwiches one at a time. Deli roast beef means no roasting or slicing, and the creamy onion spread, melted provolone, and crunchy onions give every bite layers of flavor. The seasoned butter on top bakes into a golden, savory crust, and the au jus on the side gives you the dipping you expect from a classic French dip.

Ingredient Notes:

• Hawaiian Sweet Rolls (12 rolls): Soft and slightly sweet, they balance the salty beef and cheese and stay tender when dipped. Leaving them connected makes slicing and assembling quick.
• Deli Sliced Roast Beef: The no-cook shortcut for the filling. Thin slices pile up tender and are easy to layer.
• Crispy Fried Onions: Add crunch and a toasty onion flavor that mimics the caramelized onions on a traditional French dip.
• Provolone Cheese: Melts smoothly and has a mild, slightly tangy flavor that pairs well with roast beef without overpowering it.
• Onion Soup Mix: Seasons the spread with deep, savory onion flavor.
• Mayo: Mixes with the onion soup mix into a creamy spread that adds moisture and richness to the rolls.
• Butter: Melted and brushed on top for a golden, flavorful crust.
• Au Jus Gravy Mix, divided: Half goes into the butter topping for savory flavor, and the other half is prepared as the dipping sauce.
• Garlic Powder: Adds a warm garlic note to the butter topping.
• Parsley Flakes: Adds a little color and a fresh, herby touch on top.

Directions:

Step One – Preheat oven to 350 degrees F.

Step Two – Slice Hawaiian sweet trolls lengthwise and place the bottom half into your casserole dish.

Step Three – Add all roast beef, crispy fried onions, and provolone cheese to the sweet rolls.

Step Four – In a separate bowl mix the mayo with onion soup mix and spread this on the top half of your sweet rolls. Add them on top of sliders in the casserole dish.

Step Five – In a separate bowl melt butter and mix in 1/2 of the Au Ju Gravy mix, garlic powder and parsley flakes. Brush this on top of your slider buns and place in the oven.

Step Six – Bake or 20 minutes. Meanwhile prepare the remaining Au Ju Gravy mix according to the package directions. Once cooked slice sliders and serve them with Au Ju Gravy and enjoy.

Tips for the Best French Dip Sliders

• Keep the rolls connected and cut them as one slab, which saves time and holds the layers together.
• Spread the mayo mixture all the way to the edges so every slider gets the onion flavor.
• Fold or ruffle the roast beef as you layer it, which makes the sliders thicker and more tender.
• Press the crispy onions lightly into the cheese so they stay put when you slice.
• Brush the butter on evenly, including the edges, for a golden top on every roll.
• Cover with foil first so the cheese melts before the tops brown, then uncover to crisp the tops.
• Serve the au jus in small bowls so everyone can dip their own.
