Step-by-Step Instructions

These steps are written directly from your provided instructions, expanded only for clarity and technique—but not altered in any way.

1. Caramelize the onions

In a large skillet over medium heat, melt the 3 tablespoons of unsalted butter. Add the thinly sliced onion and stir to fully coat the slices in butter. Continue cooking, stirring occasionally, for 12–15 minutes until the onions are soft, golden, and slightly brown around the edges. They should not be burned.

2. Season the onions

Remove the skillet from the heat. Add the minced fresh thyme, kosher salt, and black pepper. Stir well to combine and set the skillet aside.

3. Prepare the rolls

Preheat your oven to 350°F. Without pulling the rolls apart, remove them from the package so they are still connected. Using a large serrated knife, slice horizontally through the entire block of rolls to separate the tops from the bottoms. Place the bottom half (cut side up) into an 11×7 baking dish.

4. Build the sliders

Layer half of the provolone slices evenly over the bottom half of the rolls. Add all 14 ounces of sliced deli roast beef across the cheese layer. Spread the caramelized onions evenly over the roast beef. Add the remaining provolone slices on top. Carefully place the top half of the rolls back on.

5. Add the buttery topping

In a small bowl, stir together the melted 1/2 cup unsalted butter and the 1 1/2 tablespoons dried onion soup mix. Brush this mixture evenly over the tops of the rolls (or pour it gently if you prefer).

6. Bake

Loosely cover the baking dish with foil, ensuring the foil doesn’t touch the tops of the rolls. Bake for 25 minutes. Remove the foil and continue baking for an additional 5 minutes until the rolls are lightly browned.

7. Prepare the au jus

While the sliders bake, prepare the au jus according to the package instructions using the 3 cups of water. Keep warm for serving.

8. Finish & serve

Remove the sliders from the oven. Add optional fresh parsley over the top. Serve warm with the au jus on the side for dipping.

Tips & Variations

Make it spicy

Add a touch of crushed red pepper to the onions or sprinkle a little over the cheese.

Vegetarian option

Substitute roast beef with sautéed mushrooms—use a mix of cremini and portobello for depth, and add a splash of soy sauce to mimic the savory flavor.

Gluten-free version

Use gluten-free slider buns and a gluten-free au jus mix or homemade broth.

Cheese swaps

• Mozzarella for extra melt
• Swiss for a nutty flavor
• Havarti for a mild, buttery finish

Onion variations

Use sweet onions, red onions, or a combination for a more complex flavor.

Pantry-friendly substitutions

• Dried thyme can replace fresh thyme (use half the amount).
• Sub brioche rolls if sweet rolls are unavailable.
• Use beef broth in place of au jus if needed.

Flavor Profile & Pairings

French Dip Sliders are savory, buttery, slightly sweet from the rolls, and incredibly melt-in-your-mouth tender. The caramelized onions bring warmth and depth, while the provolone adds creamy richness that ties everything together. Dipping each bite into warm au jus enhances the flavor with satisfying saltiness and umami.

• Fresh green salad
• Crispy baked potatoes

FAQs

Ingredient Spotlight

Provolone Cheese

Provolone is a mild Italian cheese known for its smooth melt and buttery flavor. For best results, choose freshly sliced deli provolone rather than pre-packaged slices, which tend to be stiffer and melt a little less evenly.

How to Store It

Keep provolone wrapped tightly in its deli paper or place it in an airtight container in the refrigerator. Use within 5 days for best flavor.

Deli Roast Beef

Choosing a high-quality sliced roast beef elevates these sliders tremendously. Opt for freshly sliced deli beef rather than packaged versions for the most tender texture and best flavor.

How to Store It

Keep sealed in the refrigerator for up to 3–4 days.

Pro Cooking Tips

• Don’t rush the onions—slow cooking makes them sweet and rich.
• Use a serrated knife to slice the rolls cleanly.
• Brush the butter topping instead of pouring to keep distribution even.
• Keep the sliders covered during the first bake to prevent scorching.
• Let the sliders rest for 5 minutes before slicing to keep layers intact.

Storage & Freezing Guide

Refrigeration

Store leftovers in an airtight container for up to 3 days.

Freezing

Freeze baked sliders once completely cooled. Place in a freezer-safe bag or wrap tightly in foil. Freeze for up to 2 months.

Thawing

Thaw in the refrigerator overnight. Reheat in the oven for the best texture.
