Ingredients You’ll Need
- Hawaiian rolls: These soft, slightly sweet rolls form the base of your sliders. They’re light and fluffy, contrasting beautifully with the savory filling. If unavailable, any slider rolls can replace them.
- Deli sliced roast beef (1 lb): For the best results, use high-quality, thinly sliced roast beef. You can always use more if you really want that meaty goodness!
- Swiss or provolone cheese (10-12 slices): This is where the cheese lovers will rejoice! Both cheeses melt beautifully, providing that satisfying stretch. Feel free to combine both for an extra flavor kick.
- French fried onions (1 cup): These add a delightful crunch that complements the soft ingredients. You can substitute with caramelized onions for a different take.
- Butter (4 tablespoons): Helps to create that golden, crispy top. It also adds a rich flavor that ties everything together.
- Au jus gravy mix (1 packet or 1 oz): This mix provides a quick and delicious dipping sauce. It’s easy to follow, but you can make your own homemade version if you’re feeling adventurous.
- Garlic powder (½ tsp): Adds depth and aroma. Fresh minced garlic is fantastic too if you prefer.
- Onion powder (½ tsp): Enhances the overall onion flavor profile, complementing the beef and ensuring a savory taste.
- Sesame seeds (½ tsp, optional): For a little extra texture and visual appeal, though not necessary.
- Fresh parsley or thyme (for garnish, optional): Brightens up the dish visually and adds a fresh flavor.
How to Make French Onion Beef Sliders with Au Jus

Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). Lightly grease a 13×9 baking dish with cooking spray, or for easier cleanup, line it with parchment paper. This step ensures that the sliders won’t stick and makes serving and cleanup a breeze. While the oven heats up, you’ll want to get everything together.
Slice the Rolls
Remove the Hawaiian rolls from the package, making sure to keep them attached as one block. Carefully slice the rolls in half horizontally. This creates the bottom and top layers for your sliders. It’s critical to keep them still attached to maintain their structure when baking.
Layer the Cheese and Beef
Once the rolls are cut, place the bottom layer in the prepared baking dish. Lay half the cheese slices evenly over the rolls, ensuring complete coverage. Next, pile on the deli-sliced roast beef, spreading it evenly across to maximize flavor in every bite. Don’t skimp here! The roast beef is the star of the show.
Add the Crunch
Now sprinkle the French fried onions generously over the beef layer. This step adds the delightful crunch we crave, contrasting wonderfully with the savory fillings. Then, add the remainder of the cheese slices over the onions, making sure every inch is well covered; you want that melty goodness!
Top It Off
Once your layers are complete, carefully place the top half of the rolls back on to finish the sliders. This sandwich-like construction creates a perfect pocket for all that delicious filling.
Create the Savory Glaze
In a microwave-safe bowl, go ahead and melt the butter. Once melted, measure out 1 tablespoon from the au jus gravy mix packet. Stir this into the melted butter along with the garlic powder and onion powder until well combined. This buttery mixture will glaze the tops of the rolls, enhancing the flavor and aiding in the browning.
Brush and Sprinkle
With a pastry brush, apply the buttery mixture evenly over the tops of the rolls. If you fancy, you can sprinkle sesame seeds on top to elevate the presentation and flavor. The buttery glaze will also help create a beautifully golden brown top while baking.
Bake Until Golden
Pop the baking dish in the oven and bake uncovered for 15 to 20 minutes. You’ll know they’re ready when the edges are golden and crisp, and the cheese is perfectly melted. Keep an eye on them, as ovens can vary in cooking times; that golden hue is your cue.
Prepare the Au Jus
While your sliders are baking, prepare the remaining au jus according to the packet instructions. Leave out the tablespoon you measured earlier. This will ensure you still have enough flavorful dipping sauce without overpowering the sliders.
Garnish and Serve
Once your sliders are out of the oven, you can garnish them with fresh parsley or thyme if you desire, adding a pop of color and freshness. Serve these warm alongside your prepared au jus for dipping. You’ll watch them disappear before your eyes!
Tips for Success
- When slicing the rolls, ensure they are done evenly to prevent difficulty in pulling them apart later.
- For an even richer flavor, consider using a combination of Swiss and provolone cheese.
- If you don’t have time to make the sliders fresh, prep everything a few hours ahead and keep it in the fridge, then bake just before serving.
- For the ultimate texture, try toasting the butter mixture before applying it to the rolls—it enhances the flavor and gives the bread an optimal crunch.
- Make sure your au jus doesn’t boil; keep it warm for dipping instead.
Serve It With
Pair your sliders with a variety of side dishes to enhance the meal experience:
- Crunchy coleslaw: Provides a refreshing contrast to the richness of the sliders.
- Oven-baked fries: Always a fun pairing, they make for a hearty combination.
- Pickles: A tangy side that cuts through the richness.
- A simple green salad: Offers a light balance to your heavy sliders.
- Chips and dip: Perfect if you’re serving these for a party and want to add variety.
How To Store & Reheat Leftovers
- Room Temperature: The sliders can sit out for about two hours before needing refrigeration to ensure food safety due to meat.
- Refrigeration: Store leftover sliders in an airtight container for up to 3 days. When storing, consider leaving the au jus separate to maintain both components’ quality.
- Freezing: You can freeze the assembled sliders (before baking) for up to 3 months. Wrap them tightly in foil and place them in a freezer-safe bag.
- Reheating: To reheat, bake in a preheated 350°F oven for about 10 minutes, covered with foil, then uncover for the last few minutes until warm and cheese is melted. Alternatively, you can microwave a slider for about 30 seconds, though the oven method helps maintain texture better.
- Quality Notes: The sliders may not be as crisp when reheated but should still be flavorful! Refresh the flavors with a squeeze of fresh lemon over the top before serving.
Tips & Variations
- Different Cheeses: Swap Swiss or provolone for cheddar or pepper jack for a kick.
- Add Vegetables: Thinly sliced mushrooms or sautéed bell peppers can add another layer of flavor and nutrition.
- Make it Spicy: Add jalapeño slices or a drizzle of sriracha for those who like heat.
- Vegan Version: Substitute the beef with a plant-based option, and use vegan butter and cheese for a delightful alternative.
- Seasonal Flair: Incorporate seasonal ingredients like sautéed spinach or cooked butternut squash for a fall twist.
