Quick Recipe Overview

  • Prep Time: 15 minutes
  • Cook Time: 25 minutes
  • Total Time: 40 minutes
  • Servings: 12 sliders
  • Course: Appetizer, Dinner, Sandwich
  • Cuisine: American

Ingredients

For the Sliders

  • 3 tablespoons unsalted butter
  • 1 medium onion, thinly sliced
  • 2 teaspoons fresh thyme, minced
  • ¼ teaspoon kosher salt
  • ¼ teaspoon black pepper
  • 12 sweet rolls
  • 10 slices provolone cheese
  • 14 ounces sliced deli roast beef

For the Topping

  • ½ cup unsalted butter, melted
  • 1½ tablespoons dried onion soup mix

For the Au Jus

  • 1 packet au jus gravy mix
  • 3 cups water
  • Fresh chopped parsley, for garnish

Step-by-Step Instructions

1. Caramelize the Onions

Preheat your oven to 350°F (175°C).

Melt 3 tablespoons of butter in a skillet over medium heat. Add the sliced onion, thyme, kosher salt, and black pepper.

Cook for about 8–10 minutes, stirring occasionally, until the onions are soft and lightly golden. Remove from the heat.

2. Prepare the Slider Rolls

Without separating the individual rolls, carefully slice the entire package of sweet rolls horizontally. Place the bottom half in a lightly greased baking dish.

Layer the roast beef evenly over the rolls.

3. Add the Cheese and Onions

Arrange the provolone slices over the roast beef. Spoon the caramelized onions evenly across the cheese.

Place the top half of the rolls over the filling.

4. Make the Butter Topping

In a small bowl, combine the melted butter with the dried onion soup mix.

Brush the mixture generously over the tops of the rolls, making sure the butter reaches the edges.

5. Bake the Sliders

Cover the baking dish loosely with foil and bake for about 15 minutes.

Remove the foil and continue baking for another 5–10 minutes, or until the cheese is completely melted and the tops are lightly golden.

6. Prepare the Au Jus

While the sliders bake, whisk the au jus gravy mix with 3 cups of water in a saucepan.

Bring to a simmer and cook according to the package directions, stirring until smooth and slightly thickened.

7. Garnish and Serve

Sprinkle the finished sliders with fresh chopped parsley.

Separate the sliders and serve warm with individual cups or a small bowl of au jus for dipping.

Recipe Tips for Success

  • Don’t overcook the roast beef. The deli roast beef only needs to heat through in the oven.
  • Take your time with the onions. Cooking them slowly gives them a sweeter, richer flavor.
  • Keep the rolls together while slicing. This makes assembling and baking the sliders much easier.
  • Cover before baking. Foil helps keep the sliders soft while the cheese melts.
  • Uncover at the end. This gives the tops a lightly toasted, buttery finish.
  • Serve the au jus hot. The warm dipping sauce is what gives these sliders their classic French dip character.

Ingredient Substitutions

  • Provolone: Substitute mozzarella, Swiss, or a mild white cheese.
  • Sweet rolls: Hawaiian-style rolls or other soft dinner rolls work well.
  • Deli roast beef: Use thinly sliced leftover roast beef if you have it.
  • Fresh thyme: Use about ½ teaspoon dried thyme if fresh thyme isn’t available.
  • Unsalted butter: Salted butter can be used; simply reduce or omit some of the added salt.

Recipe Variations

Cheesy French Dip Sliders

Add extra provolone for an even cheesier filling.

Mushroom French Dip Sliders

Sauté thinly sliced mushrooms with the onions for a richer, heartier filling.

Spicy French Dip Sliders

Add sliced pepperoncini or a few thinly sliced jalapeños before adding the cheese.

Garlic Butter Sliders

Add a small amount of garlic powder to the melted butter topping for extra savory flavor.

Storage and Reheating

Store leftover sliders in an airtight container in the refrigerator for up to 3 days.

To reheat, place them in a covered baking dish and warm at 325°F (165°C) until heated through. Reheat the au jus separately on the stovetop.

For the best texture, avoid microwaving the sliders for too long, as the rolls can become soft.

Serving Suggestions

Serve these sliders with:

  • French fries or potato wedges
  • Crispy roasted potatoes
  • Coleslaw
  • Pickles
  • Green salad
  • Onion rings
  • Extra caramelized onions
  • Warm au jus for dipping

They’re especially good for game-day gatherings, parties, family dinners, and casual entertaining.

Frequently Asked Questions

Can I make French Dip Sliders ahead of time?

Yes. Assemble the sliders, cover them tightly, and refrigerate them for several hours before baking. Add the butter topping shortly before baking for the best texture.

What is the best cheese for French Dip Sliders?

Provolone is a classic choice because it melts smoothly and has a mild, savory flavor. Swiss or mozzarella are also good alternatives.

Can I use leftover roast beef?

Absolutely. Thinly slice leftover roast beef and use it in place of deli roast beef. Since cooked roast beef can be thicker, slice it as thinly as possible for easier slider bites.

Can I freeze these sliders?

You can freeze the assembled, unbaked sliders, but the texture of the rolls may change slightly after thawing. For the best results, freeze them well wrapped and bake after thawing.

How do I keep the sliders from getting soggy?

Don’t add the au jus directly to the sliders before baking. Bake the sandwiches separately and serve the au jus on the side for dipping.

Can I use another type of roll?

Yes. Soft dinner rolls, Hawaiian rolls, or small brioche-style rolls can all work well.

Is French Dip the same as a French sandwich?

A French dip is an American roast beef sandwich traditionally served with a savory beef-based dipping sauce called au jus. These sliders turn that idea into a smaller, party-friendly version.

  • Provolone gives these sliders a classic French dip flavor, but Swiss or mozzarella can also be used.
  • For deeper flavor, cook the onions slowly until golden and caramelized.
  • Covering the sliders during the first part of baking helps keep the rolls soft while the cheese melts.
  • Serve the au jus warm in small bowls for easy dipping.
  • These sliders are best served fresh while the cheese is hot and melted.
