8 ounces (225 g) provolone cheese, sliced: Melts beautifully and pairs perfectly with the beef.
1 pound (454 g) thin-sliced deli roast beef: Tender meat that absorbs the au jus, making every bite delectable.
1 teaspoon (1 g) dried oregano leaves: Adds an earthy note that complements the meat and cheese.

How to Make French Dip Sliders

Cook the Onions: Heat a skillet over medium heat and add the sliced onion, 3 tablespoons of the softened butter, kosher salt, and black pepper. Cook for 10 to 12 minutes, stirring occasionally, until the onions are soft and caramelized. Remove from heat and set aside.
Make the Butter Mixture: While the onions cook, mix the remaining 3 tablespoons of softened butter with 1 tablespoon of the au jus gravy mix in a small bowl until fully combined; set aside.
Prepare the Au Jus: In a small saucepan, whisk together the remaining au jus gravy mix and 2 cups of water. Heat over low heat, stirring occasionally, and keep warm for serving.
Preheat the Oven: Set the oven to 350°F (177°C). Slice the Hawaiian sweet rolls in half horizontally and place the bottom halves in a parchment paper–lined 9×13-inch baking dish or on a rimmed baking sheet.
Layer the Ingredients: Start by layering half of the provolone cheese evenly over the bottom halves of the rolls. Next, add the sliced roast beef, followed by the caramelized onions. Sprinkle the dried oregano evenly over the onions, and then add the remaining provolone cheese. Finally, place the tops of the rolls over the filling.
Add Butter & Bake: Spread the butter mixture evenly over the tops of the rolls. Cover loosely with aluminum foil and bake for 20 minutes, until the cheese is melted and the sliders are heated through.
Garnish & Serve: Remove the sliders from the oven and uncover. Sprinkle the French-fried onions and chopped parsley over the top. Serve warm with the prepared au jus on the side for dipping.

Storing & Reheating

To store leftover sliders, place them in an airtight container at room temperature for up to two hours. If you refrigerate them, consume them within 3 days for the best flavor. For longer storage, freeze the assembled sliders in a tightly sealed container for up to 3 months. To reheat, place them in a preheated oven at 350°F (177°C) for about 10-15 minutes until warmed through—this helps to maintain their soft texture and melt the cheese again.

Chef’s Helpful Tips

Avoid overcooking the onions; aim for golden brown without letting them burn to enhance their sweetness.
For a cleaner cut, warm the knife before slicing the rolls; this helps to prevent tearing.
If you’re concerned about sogginess, layer cheese between the beef and onion layers—this provides a barrier.
Make the au jus in advance and keep it warm so it’s ready when the sliders come out of the oven.
Experiment with different cheeses or add horseradish for an extra kick.

Indulging in these French Dip Sliders is like giving yourself a warm hug. Each bite is packed with flavors that complement one another beautifully, making them perfect for any occasion. Whether you set them out as an appetizer at your next gathering or enjoy them as a comforting dinner, they’re sure to impress.

Recipe FAQs

Can I make these sliders ahead of time?

Absolutely! You can assemble the sliders and store them in the refrigerator for up to 24 hours before baking. Just cover them tightly with plastic wrap. When ready to bake, remove the wrap and follow the baking instructions.

What can I substitute for roast beef?

If you want to switch it up, you can use thinly shaved turkey, ham, or even grilled portobello mushrooms for a vegetarian option. Just ensure you adjust seasoning as needed.

How can I make the au jus from scratch?

For a homemade au jus, simmer beef broth with a splash of soy sauce and a bit of garlic powder. You can enhance its flavor by adding fresh herbs like thyme or rosemary.

Can I use different types of rolls?

Yes, feel free to switch out the Hawaiian rolls for any slider buns you prefer, such as whole wheat or gluten-free options. Just keep in mind that it may slightly change the sweetness and texture of your sliders.
