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

Preparing the French Dip Sliders
Caramelizing the Onions
Let’s start by building a deep flavor base for our French Dip Sliders. In a large skillet, melt the 3 tablespoons of unsalted butter over medium heat. Once the butter is shimmering, add your thinly sliced medium onion. We want to cook these onions low and slow until they are beautifully softened and begin extract to turn a rich, golden brown. This process can take anywhere from 15 to 25 minutes, so be patient! Stir them occasionally to prevent sticking. Once the onions are nicely caramelized, stir in the minced fresh thyme, 1/4 teaspoon of kosher salt, and 1/4 teaspoon of black pepper. Cook for another minute until the thyme is fragrant. This aromatic mixture will be a star player in our sliders.
Assembling the Sliders
Now it’s time to bring our sliders together. Slice your 12 sweet rolls in half horizontally. If your rolls are on the larger side, you might consider a slightly more generous amount of roast beef per slider. Arrange the bottom halves of the rolls on a large baking sheet, cut-side up. Layer about half of the provolone cheese slices evenly over the bottom of the rolls. Next, we’ll pile on the 14 ounces of sliced deli roast beef. Don’t be shy – we want a hearty portion of roast beef on each slider! Once the roast beef is in place, top it with the remaining provolone cheese slices. Finally, spoon the caramelized onion mixture evenly over the cheese. This combination of savory beef, melted cheese, and sweet, caramelized onions is what makes these French Dip Sliders so irresistible.
Creating the Au Jus Dipping Sauce
No French Dip is complete without its signature au jus! In a medium saucepan, combine the 3 cups of water with the 1 packet of au jus gravy mix and the 1 & 1/2 tablespoons of dried onion soup mix. Whisk everything together thoroughly to ensure there are no lumps. Bring this mixture to a gentle simmer over medium heat. Let it simmer for about 5-10 minutes, stirring occasionally, until the gravy has thickened slightly and the flavors have melded. The dried onion soup mix adds an extra layer of savory goodness that complements the au jus perfectly. Keep this au jus warm on the stovetop while you finish assembling and baking the sliders. It’s essential for that authentic French Dip experience.
Baking and Finishing the Sliders
Carefully place the top halves of the sweet rolls over the filled bottom halves. Now, for the final touch that makes them golden and glorious: whisk together the 1/2 cup of melted unsalted butter. Brush this melted butter generously over the tops of all 12 sliders. This butter will help the rolls become wonderfully toasted and slightly crispy. Place the baking sheet with the assembled sliders into a preheated oven at 350°F (175°C). Bake for about 10-15 minutes, or until the rolls are golden brown and the cheese is completely melted and bubbly. Keep an eye on them to prevent burning, as oven temperatures can vary. The aroma filling your kitchen at this point will be incredible!
Serving the French Dip Sliders
Once the sliders are out of the oven, they are ready to be served! You can either serve them whole, or if you prefer, carefully cut them into individual sliders with a sharp knife. Arrange them on a platter. Pour the warm au jus into small ramekins or a serving bowl, making sure to get all those delicious bits from the bottom of the saucepan. The beauty of French Dip Sliders is the interactive element. Guests can dip their sliders into the rich, savory au jus as much or as little as they like. For an extra pop of color and freshness, you can sprinkle some fresh chopped parsley over the sliders just before serving, though this is entirely optional. Enjoy these delightful mini sandwiches!

Frequently Asked Questions:
Can I make the au jus ahead of time?
Absolutely! The au jus can be made up to 2 days in advance and stored in an airtight container in the refrigerator. Gently reheat it on the stovetop or in the microwave before serving. This is a great way to save time if you’re preparing these French Dip Sliders for a party.
What are some good variations for these French Dip Sliders?
We love the classic, but you can definitely mix things up! Consider adding caramelized onions for an extra layer of sweetness, a sprinkle of Gruyère or provolone cheese for added richness, or even a touch of horseradish sauce for a little kick. Some people even like to add a thin slice of pickle for a briny contrast.
How should I reheat leftover French Dip Sliders?
The best way to reheat these French Dip Sliders is in a moderate oven (around 300°F or 150°C) for about 10-15 minutes, or until warmed through. This helps to maintain the integrity of the bread and the fillings. Avoid microwaving if possible, as it can make the bread soggy.
