I love how this recipe brings all the richness of a classic French dip into a bite-sized, handheld version that’s ready in just 20 minutes. The combo of savory roast beef, gooey melted cheese, and buttery slider buns with a golden finish is seriously irresistible. I also enjoy how the French onion soup does double duty — warming up the beef and serving as the flavorful dipping jus on the side. Minimal prep, maximum payoff.

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

1 pound roast beef, thinly sliced
10.5 ounces French onion soup
2/3 cup water (½ soup can of water)
9 King’s Hawaiian slider buns
9 slices Provolone cheese
2 tablespoons unsalted butter
⅛ teaspoon kosher salt
⅛ teaspoon garlic powder
chopped parsley for garnish (optional)

Directions

I start by preheating the oven to 350°F (175°C).
In a saucepan, I warm up the French onion soup and water over medium heat.
I add the thinly sliced roast beef to the soup and heat until warmed through.
On a rack set inside a baking pan, I place the bottom halves of the slider buns and top each with a slice of provolone cheese.
I evenly layer the heated roast beef over the cheese.
Using a slotted spoon, I scoop out the onions from the soup and spread them over the beef.
I place the top halves of the buns on the sliders.
In a microwave-safe bowl, I melt the butter, then stir in the salt and garlic powder.
I brush the seasoned butter evenly over the bun tops.
I bake the sliders for about 5 minutes, just until the cheese melts and the buns are lightly toasted.
I remove them carefully from the oven and serve warm with the leftover soup as au jus for dipping.

Servings and timing

This recipe makes 9 sliders and takes just 20 minutes from start to finish — 10 minutes to prep and another 10 to bake. Perfect for a quick dinner or a game-day snack that I can throw together fast.

Variations

When I want to switch things up, I like to use Swiss or Gruyère cheese instead of provolone for a nuttier flavor. If I’m craving a little heat, I’ll add a few sliced banana peppers or a swipe of horseradish sauce before layering on the roast beef. For a more rustic flavor, crusty dinner rolls also work in place of the Hawaiian buns, though I do love that touch of sweetness they add.

Storage/Reheating

If I have any leftovers, I store them in an airtight container in the fridge for up to 2–3 days. To reheat, I wrap them in foil and place them in a 350°F oven for about 10 minutes. This keeps the buns soft while bringing back that melty cheese goodness.

FAQs

What’s the best roast beef to use for these sliders?

I like using thinly sliced rare roast beef from the deli counter. It stays tender and reheats quickly in the French onion broth without drying out.

Can I make these sliders ahead of time?

Yes, I assemble them ahead but hold off on brushing the butter or baking until I’m ready to serve. That way, they stay fresh and don’t get soggy.

Can I use homemade French onion soup?

Absolutely. If I have time, homemade soup adds a deeper flavor, but store-bought works great in a pinch.

What can I use instead of King’s Hawaiian buns?

I sometimes use mini brioche buns or soft dinner rolls. Anything soft and slightly sweet gives a great balance to the savory filling.

How do I serve these for a crowd?

I double or triple the recipe and bake them in large batches. I like serving them right on the baking sheet with small ramekins of au jus for dipping.

Conclusion

These French Dip Sliders are one of my go-to quick meals when I want something warm, hearty, and full of flavor without spending a lot of time in the kitchen. They’re easy to adapt, perfect for gatherings or weeknight dinners, and that dip in the jus takes them over the top. Once I tried them, they became an instant favorite in my rotation.
