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)
Preparing the Onion and Herb Mixture
Sautéing the Onions
Start 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 the thinly sliced medium onion. We want to cook these onions down until they are softened and nicely caramelized, which will bring out their natural sweetness and add a wonderful depth of flavor. Stir them occasionally to prevent sticking, and this process will likely take about 8-10 minutes. Patience here is key for great flavor!
Adding Aromatics
Once the onions are tender and starting to turn a beautiful golden brown, it’s time to add the fresh thyme. Sprinkle in 2 teaspoons of minced fresh thyme, along with 1/4 teaspoon of kosher salt and 1/4 teaspoon of black pepper. Stir everything together well and cook for another minute or two until the thyme becomes fragrant. This step really wakes up the aromatics and infuses the onions with their herbaceous notes. Remove the skillet from the heat and set this delicious onion and herb mixture aside.
Assembling the Sliders
Preparing the Rolls and Roast Beef
Now, let’s get the sliders ready for assembly. Take your 12 sweet rolls and carefully slice each one in half horizontally. This will create the tops and bottoms for your sliders. Arrange the bottom halves of the rolls in a single layer in a 9×13 inch baking dish. Next, take your 14 ounces of sliced deli roast beef. You’ll want to gently separate the slices so they don’t stick together too much. Layer the roast beef evenly over the bottom halves of the sweet rolls in the baking dish. Don’t be afraid to let it pile up a little; we want a generous roast beef filling in every slider!
Adding Cheese and Onions
It’s time to add the provolone cheese, which will melt beautifully and bind everything together. Place 10 slices of provolone cheese on top of the roast beef layers. Try to cover as much of the roast beef as possible with the cheese. Following the cheese, evenly distribute the sautéed onion and herb mixture that you prepared earlier over the cheese. Make sure you get a good amount of those sweet, savory onions onto each slider.
Making the Dipping Au Jus
Combining Gravy Mix and Water
While the sliders are getting ready to bake, let’s prepare the essential au jus for dipping. In a medium saucepan, combine 3 cups of water with 1 packet of au jus gravy mix and 1 & 1/2 tablespoons of dried onion soup mix. Whisk these ingredients together thoroughly to ensure there are no clumps, especially from the gravy mix.
Simmering the Au Jus
Place the saucepan over medium-high heat and bring the mixture to a boil. Once it starts to boil, immediately reduce the heat to low and let it simmer gently for about 5-7 minutes. This simmering time allows the flavors to meld together and the sauce to thicken slightly. Stir occasionally to prevent the bottom from scorching. Once it has simmered, remove it from the heat and set it aside. This rich, savory liquid will be your dipping sauce.
Baking the French Dip Sliders
Butter and Baking Instructions
Now it’s time to bring it all together! Carefully pour the melted 1/2 cup of unsalted butter evenly over the tops of the sweet rolls in the baking dish. This butter will soak into the rolls, making them golden brown and delicious as they bake. Make sure to get all the nooks and crannies. Cover the baking dish tightly with aluminum foil. Place the covered baking dish into a preheated oven at 350 degrees Fahrenheit (175 degrees Celsius). Bake for 15 minutes, then remove the foil and bake for another 10-15 minutes, or until the rolls are golden brown and the cheese is melted and bubbly.
Serving and Garnishing
Once the sliders are beautifully baked, carefully remove the baking dish from the oven. You can garnish with fresh chopped parsley if you like, for a pop of color and freshness. Serve the French Dip Sliders immediately with the warm au jus in small bowls for dipping. These are best enjoyed fresh, while the cheese is still gooey and the rolls are warm and soft. Enjoy this crowd-pleasing appetizer or quick meal!

FAQs:
Can I make the roast beef ahead of time for the French Dip Sliders?
Absolutely! You can easily prepare the roast beef and the au jus a day or two in advance. Store them separately in airtight containers in the refrigerator. When you’re ready to assemble your French Dip Sliders, simply reheat the roast beef gently and warm the au jus. This is a fantastic way to save time, especially if you’re hosting a group.
What kind of bread is best for French Dip Sliders?
While slider buns or small rolls are ideal for the “slider” format, a soft but sturdy bread is key. Brioche buns offer a slight sweetness that complements the savory beef wonderfully. Alternatively, small baguette sections or even Hawaiian rolls can work. The most important thing is that the bread can hold up to the moisture from the au jus without becoming too soggy.
