Ingredients

• 1lb deli sliced roast beef (or more!): Layer on a generous amount of deli-sliced roast beef for that tender, savory filling that makes these sliders so delicious.

• 10-12 slices swiss or provolone cheese (or half/half of both), divided: Melt in the flavor with slices of Swiss or provolone cheese (or a mix of both!), this cheese adds that perfect creamy, gooey texture.

• 1 cup French fried onions: Add a crispy crunch with French fried onions that bring texture and a burst of flavor to every bite.

• 4 tbsp butter: Melted butter is the secret ingredient to making these sliders golden, crispy, and irresistibly delicious.

• 1 packet (1oz) au jus gravy mix: For the dipping sauce that pulls it all together, you’ll need a packet of au jus gravy mix, it adds rich, savory flavor.

• ½ tsp garlic powder: A pinch of garlic powder adds just the right touch of savory depth to the sliders.

• ½ tsp onion powder: Onion powder complements the garlic perfectly and gives the sliders an extra layer of flavor.

• ½ tsp sesame seeds for garnish (optional): Top it off with a sprinkle of sesame seeds for an optional, but tasty, garnish that adds a bit of extra flair.

• Fresh parsley or fresh thyme for garnish (optional): Fresh parsley or thyme gives these sliders a touch of freshness and a pop of color, making them look as good as they taste.

Step-by-Step Instructions

You can find a printable recipe card at the bottom of this post.

1. Preheat your oven to 350℉.

2. Spray the bottom of a 13×9 pan or baking dish, or simply line with parchment paper or nonstick foil.

3. Remove your Hawaiian rolls from the package, keeping the rolls together and not pulling them apart. Carefully slice the whole block of rolls in half horizontally and separate the whole top layer from the bottom layer.

4. Place the bottom layer into your prepared pan.

5. Lay down your first half of cheese slices across the bottom layer, covering the surface.

6. Next, pile on the deli-sliced roast beef evenly over the cheese layer.

7. Sprinkle the French fried onions evenly all over the beef.

8. Lay down the remaining slices of cheese evenly across the top of the onion layer, covering the whole surface.

9. Place the top layer of the rolls on top.

10. In a small glass or heat-safe dish, melt the butter in the microwave.

11. Remove one tbsp from the packet of au jus gravy mix.

12. Add the 1 tbsp au jus gravy mix, garlic powder, and onion powder to the melted butter and stir until combined.

13. Brush the melted butter mixture all over the top of the rolls.

14. If using sesame seeds, sprinkle them across the top of the rolls.

15. Place the pan of sliders into the oven uncovered, and let cook for 15-20 minutes until browned and crisp on top and cheese is melted.

16. Meanwhile, prepare the au jus mix if you would like to use it for dipping the sandwiches in. Simply prepare the mix according to the directions of the packet. It won’t make a huge difference that 1 tbsp was removed from the packet- it will still come out just as flavorful to dip the sliders into.

17. Once the sliders come out of the oven, garnish with fresh parsley or thyme if desired.

17. Serve with au jus on the side for dipping if desired.

Tips for the Perfect French Onion Beef Dip Sliders

• Use quality beef: Go for deli-sliced roast beef for the best flavor, and don’t be afraid to load it up. The more beef, the better!

• Don’t skimp on the cheese: Make sure each slider has plenty of Swiss or provolone cheese for that gooey, melty goodness. Mixing both cheeses gives a perfect balance of flavor.

• Brush that buttery goodness: Be sure to evenly brush the buttery au jus mix over the top of the rolls. It’ll give the sliders that golden, crispy finish you’re craving.

• Crisp up the rolls: Bake the sliders just until the tops are golden brown and the cheese is perfectly melted. You want a little crunch without overdoing it.

• Don’t forget the dip: The au jus gravy mix isn’t just for flavoring the sliders; it’s the ultimate dipping sauce! Make sure you have some on the side for that extra punch of savory goodness.

• Garnish for a fresh finish: A little sprinkle of fresh parsley or thyme adds a pop of color and freshens up the rich, savory flavors of the sliders. It makes them look as good as they taste!

• Make it ahead: These sliders are great for prepping in advance! Assemble them, cover, and refrigerate for a few hours or overnight, just pop them in the oven when you’re ready to serve. Perfect for stress-free entertaining.

Get Creative!

• Switch up the cheese: Try different cheese combinations like cheddar and gouda for a smoky twist or mozzarella for extra stretchiness. The options are endless!

• Add some kick: If you like a little heat, throw in some jalapeño slices or drizzle a bit of hot sauce over the beef before adding the cheese. It’ll bring a nice spicy contrast to the richness.

• Switch the beef: Swap out roast beef for other deli meats like turkey or ham, or even shredded chicken for a lighter option. You can also use a beef brisket or pulled pork for a more robust flavor.

• Sneak in some veggies: Add caramelized onions, sautéed mushrooms, or even spinach for extra flavor and texture. It’s a great way to sneak in some greens without compromising on taste.

• Make it a slider bar: Set up a mini slider bar with different toppings like pickles, sautéed peppers, or different sauces (think BBQ, ranch, or even buffalo sauce). Let everyone build their own perfect slider!

• Play with the buns: Experiment with different types of rolls – sesame, pretzel, or even soft dinner rolls. You could even try a low-carb option like cloud bread or lettuce wraps for a twist!

Serving & Storing

• Serving tip: These sliders are perfect for sharing at parties, family gatherings, or game days. Serve them with a side of crispy fries, chips, or a light salad for a complete meal. Don’t forget the au jus for dipping, it’s a must!

• Keep them warm: If you’re serving these sliders at a party, you can keep them warm in a slow cooker on the “keep warm” setting or wrapped in foil in the oven for a bit. That way, your guests can enjoy them fresh and hot throughout the event.

• Storing leftovers: Leftovers? No problem! These sliders store well in an airtight container in the fridge for up to 3 days. Just reheat them in the oven at 350°F for about 10 minutes to bring back that crispy texture.

• Freezing option: You can freeze these sliders before baking. Assemble the sliders, cover tightly with plastic wrap and foil, and freeze for up to 3 months. When you’re ready to enjoy, just bake them from frozen at 350°F for 20-25 minutes.

• Perfect for meal prep: These sliders make a great meal prep option! Assemble them in advance, and store the unbaked sliders in the fridge overnight. Pop them in the oven when you’re ready for an easy, comforting dinner.
