These French dip sliders are Hawaiian rolls stuffed with roast beef, caramelized onions, and cheese. Super easy to make and perfect for a large crowd!

If you love sliders, then you'll definitely enjoy these ham and cheese sliders and tuna melt sliders.

Why I Love These French Dip Sliders

• They're made with store-bought deli meat and store-bought Hawaiian rolls so all you have to do is assemble them and pop them in the oven!
• Perfect for entertaining, birthday parties, game day, and busy weeknights.
• They're incredibly flavorful, the caramelized onions, melty cheese, and au jus gravy add so much flavor.
• Absolutely delicious!

Ingredient Notes

Au Jus Gravy Mix – I used store-bought.

Roast Beef – Purchased at the deli. If you're not a fan of roast beef, feel free to use sliced turkey, ham, or chicken.

Dried Onion Soup Mix – Store-bought.

How To Make

1. Add some butter to a skillet and melt over medium heat. Add the onions and sugar, cook for 15 minutes stirring frequently. Season with salt, pepper, and thyme. Remove it from the heat and set it aside.
2. Preheat the oven to 350 degrees F.
3. Take the rolls out of the package, leaving the rolls intact. Take a large knife and slice the rolls across so you have the tops and bottom separated. Place the bottom, cut side up into a baking dish. Top with half of the cheese. Add the roast beef. Top with the onions, spreading them out. Add the remaining cheese, then add the tops of the rolls on top.
4. In a small bowl stir together the melted butter and onion soup mix. I like to brush this mixture on top of the rolls to make sure it's evenly distributed but you can just pour the butter sauce on top.
5. Cover loosely with foil, make sure the foil is not touching the tops of the rolls, and bake for 25 minutes. Uncover and bake an additional 5 minutes to brown the rolls.
6. While the rolls are baking, prepare the au jus per the package directions with the water. Serve the rolls with an optional garnish of parsley and au jus on the side for dipping.

Top Tips For The Perfect Sliders

• You don't need the au jus mix! These sliders are just as good without the onion mix and au jus. Just the roast beef, caramelized onions, and provolone cheese are incredible when served on rolls.
• Feel like taking these to the next level? Make your own onions rolls!
• Add whatever toppings you want. If you love mayo and ketchup, add some.
• I used provolone cheese but feel free to use cheddar cheese or mozzarella cheese.
