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, split horizontally
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)

Caramelizing the Onions

Begin extract by preparing the flavorful base for your French Dip Sliders. In a large skillet, melt 3 tablespoons of unsalted butter over medium heat. Once the butter is shimmering and fragrant, add your thinly sliced medium onion. Stir the onions to coat them evenly with the butter.
Allow the onions to cook, stirring occasionally, for about 20-30 minutes. The goal here is to caramelize them, meaning you want them to soften, turn golden brown, and become wonderfully sweet. Don’t rush this step; slow and steady wins the race for maximum flavor. If the onions start to stick to the bottom of the pan, you can add a tablespoon of water to deglaze and scrape up any browned bits, which are packed with flavor.
Once the onions have reached a rich golden-brown hue and a tender consistency, stir in the minced fresh thyme, kosher salt, and black pepper. Cook for another minute until the thyme is fragrant, ensuring its delicate herbal notes are released into the caramelized onions. Remove the skillet from the heat and set aside. These beautifully sweet and savory onions will be a key component of your sliders.

Assembling and Baking the Sliders

Now, let’s assemble these delightful sliders. Take your 12 split sweet rolls and arrange the bottom halves in a single layer in a 9×13 inch baking dish. Don’t worry if they’re a little snug; they’ll meld together as they bake.
Next, evenly distribute the thinly sliced deli roast beef over the bottom halves of the rolls. Aim for a generous, even layer to ensure every bite is packed with meaty goodness. Don’t be afraid to let the beef drape a little; it will soften as it bakes.
Layer the provolone cheese slices on top of the roast beef. For these sliders, I like to use about 10 slices, ensuring that each slider gets a good amount of gooey, melted cheese. The provolone’s mild, creamy flavor pairs perfectly with the roast beef and caramelized onions. Then, spoon the caramelized onion mixture evenly over the cheese. Make sure to get all those flavorful bits into the dish!

Preparing the Au Jus Dipping Sauce

While the sliders are assembling, it’s time to prepare the essential au jus for dipping. In a medium saucepan, combine the melted 1/2 cup of unsalted butter, the dried onion soup mix, and the au jus gravy mix. Whisk these together until they are well combined.
Gradually whisk in the 3 cups of water. Continue to whisk until you have a smooth, lump-free mixture. Place the saucepan over medium heat and bring the mixture to a gentle simmer. Let it simmer for about 5-10 minutes, stirring occasionally, until the au jus has thickened slightly and the flavors have melded beautifully. This rich, savory broth is what makes French Dip Sliders so special.

Baking and Serving the French Dip Sliders

Now it’s time to bake your sliders to golden perfection. Place the top halves of the sweet rolls over the assembled sliders. You can brush the tops of the rolls with a little extra melted butter if you like, for an added touch of richness and to help them crisp up.
Cover the baking dish tightly with aluminum foil. Bake in a preheated oven at 350°F (175°C) for about 15-20 minutes. This steaming period allows the rolls to soften slightly and absorb some of the delicious juices from the roast beef and onions, and most importantly, it melts the cheese beautifully.
After the initial baking time, remove the aluminum foil and bake for another 5-7 minutes, or until the tops of the rolls are lightly golden brown and toasted. Keep a close eye on them to prevent burning. The cheese should be fully melted and wonderfully gooey.
Once baked, carefully remove the sliders from the oven. You can garnish them with fresh chopped parsley if desired for a pop of color and freshness. Serve the French Dip Sliders immediately, accompanied by small bowls of the warm au jus for dipping. Encourage your guests to generously dip each slider into the rich broth before taking a bite. Enjoy the incredibly satisfying combination of tender roast beef, melted provolone, sweet caramelized onions, and soft rolls dipped in savory au jus!
