French Dip Sliders Recipe
Introduction
French Dip Sliders are a perfect crowd-pleaser, offering tender roast beef, melted provolone, and savory caramelized onions nestled in soft sweet rolls. Served with flavorful au jus for dipping, these sliders make for an irresistible appetizer or meal.

Ingredients
- 3 tablespoons unsalted butter
- 1 medium onion, thinly sliced
- 2 teaspoons fresh thyme, minced
- 1/4 teaspoon kosher salt
- 1/4 teaspoon black pepper
- 12 sweet rolls
- 10 slices provolone cheese
- 14 ounces sliced deli roast beef
- 1/2 cup unsalted butter, melted
- 1 1/2 tablespoons dried onion soup mix
- 1 packet au jus gravy mix
- 3 cups water
- Fresh chopped parsley for garnish (optional)
Instructions
- Step 1: In a large skillet over medium heat, melt the butter. Add the sliced onions and coat them in the butter. Cook, stirring occasionally, for about 12-15 minutes until the onions are soft and browned but not burnt.
- Step 2: Stir in the minced thyme, kosher salt, and black pepper, then remove from heat and set aside.
- Step 3: Preheat the oven to 350°F (175°C). Carefully slice the sweet rolls horizontally to separate the tops from the bottoms, keeping the rolls intact.
- Step 4: Place the bottom halves of the rolls, cut side up, in an 11×7-inch baking dish. Layer half of the provolone cheese slices over the bottoms.
- Step 5: Add the sliced roast beef evenly over the cheese, then spread the caramelized onions on top. Follow with the remaining cheese slices, and place the top halves of the rolls on to close the sliders.
- Step 6: In a small bowl, mix together the melted butter and dried onion soup mix. Brush this mixture evenly over the tops of the rolls for a flavorful crust.
- Step 7: Cover the baking dish loosely with foil, ensuring the foil does not touch the rolls. Bake for 25 minutes, then remove the foil and bake for an additional 5 minutes to brown the tops.
- Step 8: While the sliders bake, prepare the au jus gravy according to the package instructions using 3 cups of water.
- Step 9: Serve the sliders warm, garnished with fresh chopped parsley if desired, and the au jus on the side for dipping.
Tips & Variations
- For extra flavor, try adding a thin layer of horseradish sauce or Dijon mustard under the cheese before baking.
- Use different cheese varieties like Swiss or cheddar to customize the flavor.
- To keep rolls from getting soggy, layer the cheese both under and over the roast beef.
- Leftover sliders can be reheated in the oven wrapped in foil to maintain softness.
Storage
Store any leftover sliders covered in the refrigerator for up to 3 days. Reheat in a 350°F oven wrapped loosely in foil until warmed through to preserve moisture. Refrigerate unused au jus in an airtight container and reheat gently on the stove before serving.

Can I prepare these sliders ahead of time?
Yes, you can assemble the sliders a few hours ahead and refrigerate them unbaked. Just add the butter mixture and bake before serving.

Ingredients
Slider Ingredients
- 3 tablespoons unsalted butter
- 1 medium onion, thinly sliced
- 2 teaspoons fresh thyme, minced
- 1/4 teaspoon kosher salt
- 1/4 teaspoon black pepper
- 12 sweet rolls
- 10 slices provolone cheese
- 14 ounces sliced deli roast beef
Topping and Sauce Ingredients
- 1/2 cup unsalted butter, melted
- 1 & 1/2 tablespoons dried onion soup mix
- 1 packet au jus gravy mix
- 3 cups water
- Fresh chopped parsley for garnish (optional)
Instructions
- Caramelize the onions: In a large skillet over medium heat, melt the butter. Add the sliced onions and coat them in the butter. Cook, stirring occasionally, for 12-15 minutes until the onions are soft and browned but not burnt. Stir in the minced thyme, kosher salt, and black pepper. Remove from heat and set aside.
- Preheat the oven: Set your oven to 350°F (175°C) to prepare for baking the sliders.
- Prepare the rolls: Without separating the rolls, slice them horizontally with a large knife to separate the tops from the bottoms. Place the bottom halves, cut side up, in an 11×7-inch baking dish.
- Assemble the sliders: Layer half of the provolone cheese over the bottom rolls. Next, add the sliced deli roast beef, followed by a generous spread of the caramelized onions. Top with the remaining cheese slices, then place the roll tops over the cheese.
- Make the butter topping: In a small bowl, combine the melted butter and dried onion soup mix. Brush this mixture evenly over the tops of the rolls, or pour gently to cover them thoroughly.
- Bake the sliders: Loosely cover the baking dish with foil, avoiding contact with the roll tops. Bake for 25 minutes. Then remove the foil and continue baking for an additional 5 minutes to brown the tops.
- Prepare the au jus: While the sliders bake, prepare the au jus gravy mix according to the package instructions using 3 cups of water.
- Serve: Garnish the baked sliders with fresh chopped parsley if desired, and serve warm with the au jus on the side for dipping. Enjoy your flavorful French Dip Sliders!
Notes
- Use sweet rolls for a slightly sweet contrast to the savory roast beef and cheese.
- Be careful not to burn the onions while caramelizing for best flavor.
- Loosely covering the sliders with foil prevents the tops from burning while allowing even baking.
- The au jus gravy mix enhances the dipping experience but can be made from scratch if preferred.
- These sliders are great for parties and can be easily doubled or halved depending on the number of guests.
