Easy French Dip Sliders Recipe

Why You’ll Love This Recipe

I love this recipe because it’s simple to assemble and always delivers incredible flavor. The caramelized onions add sweetness that pairs perfectly with the savory roast beef, while the melted provolone creates a rich, cheesy layer in every bite. I also appreciate that the sliders can feed a crowd with very little effort, making them ideal for gatherings or busy weeknights. The warm au jus takes these sandwiches to another level by adding extra moisture and bold flavor with every dip.

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

• 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
• ½ cup unsalted butter, melted
• 1½ tablespoons dried onion soup mix
• 1 packet au jus gravy mix
• 3 cups water
• Fresh chopped parsley for garnish (optional)

Directions

1. I melt the butter in a large skillet over medium heat and add the sliced onions. I cook them for about 12 to 15 minutes, stirring occasionally, until they’re soft, golden brown, and caramelized.
2. I stir in the fresh thyme, salt, and black pepper, then remove the onions from the heat and set them aside.
3. I preheat my oven to 350°F. Keeping the rolls connected, I slice them horizontally to separate the tops from the bottoms. I place the bottom half into an 11 x 7-inch baking dish with the cut side facing up.
4. I layer half of the provolone cheese over the rolls, followed by the sliced roast beef. Then I evenly spread the caramelized onions over the beef before adding the remaining provolone slices. Finally, I place the tops of the rolls back on.
5. In a small bowl, I combine the melted butter with the dried onion soup mix. I generously brush the butter mixture over the tops of the rolls, making sure they’re evenly coated.
6. I loosely cover the baking dish with foil, ensuring it doesn’t touch the tops of the rolls. I bake the sliders for 25 minutes, then remove the foil and continue baking for another 5 minutes until the tops are beautifully golden.
7. While the sliders bake, I prepare the au jus according to the package directions using the water. Once the sliders are ready, I garnish them with fresh parsley if desired and serve them warm alongside small bowls of au jus for dipping.

Variations

I sometimes replace the provolone with Swiss cheese for a slightly nuttier flavor or use mozzarella for an extra cheesy bite. When I want more richness, I spread a thin layer of horseradish sauce or Dijon mustard on the rolls before assembling the sliders. I also enjoy adding sautéed mushrooms alongside the onions for an earthy flavor. For a touch of freshness, I occasionally add baby spinach after baking. If I want a little kick, I sprinkle crushed red pepper flakes into the butter glaze.

Storage/Reheating

I store leftover sliders in an airtight container in the refrigerator for up to 3 days. When I’m ready to enjoy them again, I reheat them in a 325°F oven for about 10 to 15 minutes until they’re warmed through and the cheese has melted again. If I’m in a hurry, I microwave individual sliders for about 30 to 60 seconds, although I find the oven keeps the rolls much crispier. I store any leftover au jus separately in the refrigerator and gently reheat it before serving.

FAQs

Can I make these sliders ahead of time?

I often assemble the sliders several hours ahead, cover them tightly, and refrigerate them until I’m ready to bake. I add the butter topping just before they go into the oven for the best results.

What is the best cheese for French Dip Sliders?

I usually choose provolone because it melts beautifully and complements the roast beef perfectly. Swiss, mozzarella, or white American cheese are also excellent choices.

Can I use leftover roast beef instead of deli meat?

Yes. I like using thinly sliced leftover roast beef whenever I have it. It gives the sliders an even richer homemade flavor.

Can I freeze these sliders?

I freeze the baked sliders without the au jus in a freezer-safe container for up to 2 months. I thaw them overnight in the refrigerator before reheating in the oven.

What should I serve with French Dip Sliders?

I enjoy serving these sliders with crispy fries, potato chips, coleslaw, pasta salad, roasted vegetables, or a fresh green salad. The warm au jus is always essential for dipping.
