Pin it
These are the kind of sliders that disappear before you set the plate down. I make them when I need something hot and filling but don't want to stand over the stove all night. The rolls turn golden and crisp on top while the cheese gets stretchy inside, and that little cup of warm au jus on the side makes every bite taste like a real French dip sandwich shrunk down to party size.
What goes into the pan
A short list that rewards good deli meat and real butter. Buy the best roast beef your counter has and a block of provolone that melts smoothly. The onions are the secret weapon here, so don't skip them.
- Hawaiian sweet rolls. The soft, slightly sweet base that contrasts with the savory beef and soaks up the au jus without falling apart.
- Deli roast beef. Thinly sliced and piled high; it warms through in the oven and stays tender as long as you don't overcook it.
- Provolone cheese. Mild and melty, it binds the beef to the bread and gives that pull-apart stretch.
- Yellow onion. Cooked down until sweet and jammy, adding real French onion flavor.
- Beef broth. The foundation of the dipping jus; use low-sodium so you control the salt.
- Worcestershire sauce. Adds deep umami and that classic French dip backbone.
- Butter and garlic. Brushed over the tops so the rolls bake up glossy and crisp.
- Dried thyme. A subtle earthy note that ties the meat and broth together.
How they come together
- Caramelize the onion. Melt one tablespoon butter in a skillet over medium-low heat. Add the sliced onion and cook, stirring occasionally, for twelve to fifteen minutes until soft and golden. Season lightly with salt and pepper.
- Make the au jus. Simmer beef broth, one teaspoon Worcestershire, and thyme in a small saucepan for about five minutes. Keep it warm on the back burner.
- Build the sliders. Slice the entire tray of rolls in half horizontally without separating the individual rolls. Layer the bottom half with roast beef, then provolone, then a spoonful of the caramelized onions. Replace the top half.
- Brush and bake. Melt the remaining butter with the minced garlic and brush generously over the roll tops. Cover with foil and bake at 350°F for ten minutes, then uncover and bake five more minutes until the cheese is melted and the tops are toasted.
- Serve hot. Cut into individual sliders and set out the warm au jus in small bowls for dipping.
The onion makes the difference
Soft, sweet onions separate a great French dip slider from a plain roast beef sandwich. Cook them slowly in butter over medium-low heat until they collapse and turn golden, about twelve to fifteen minutes. If you rush it over high heat they burn and turn bitter.

Cheese that melts just right
Provolone is my go-to because it melts into thin, creamy sheets without overwhelming the beef. Swiss works too, but it can get a little stringy. If you only have mozzarella on hand, use it, though the flavor will be milder. The key is covering the beef completely so the cheese acts like a glue between the meat and the roll.
Keep the bread crisp
Hawaiian rolls are soft by design, which means they can turn mushy if the beef is too wet. Pat the roast beef with a paper towel before layering, and never pour au jus inside the sandwich. The garlic butter on top is enough fat to toast the crust. Bake covered first so the cheese melts, then uncovered so the tops turn golden without drying out the middle.
Leftovers and reheating
Wrap leftover sliders tightly and refrigerate for up to three days. Reheat them uncovered on a baking sheet at 325°F for about ten minutes. The oven brings the tops back to a crunch far better than a microwave, which steams the bread. You can also freeze assembled but unbaked sliders for up to one month. Bake from frozen, covered, adding an extra five minutes.
Sides that complete the plate
These sliders are rich, so I like something sharp or crunchy alongside. Dill pickles, a simple coleslaw, or a vinegar-dressed green salad balance the salt and butter. For a bigger spread, pair them with Easy Hot Ranch Sausage Dip before the meal. The USDA recommends reheating beef to an internal temperature of 165°F when using leftovers, see the USDA roast beef safety guide.
FAQs
- Can I use frozen Hawaiian rolls?
Yes, but thaw them completely first so they bake evenly. Cold rolls in the center will stay doughy while the tops brown too fast.
- What cut of roast beef works best?
Thinly sliced deli roast beef is ideal because it warms through quickly without drying out. Ask for rare or medium-rare slices if your deli offers a choice.
- Can I make these ahead of time?
Absolutely. Assemble the sliders up to four hours ahead and keep the tray wrapped in the refrigerator. Brush with garlic butter right before baking.
- How do I keep the rolls from getting soggy?
Pat the roast beef with a paper towel before layering, and never pour au jus inside the sandwich. The garlic butter on top is enough fat to toast the crust beautifully.
- Can I use a different cheese?
Swiss, mozzarella, or Gruyere all work well. Provolone is classic for its mild flavor and smooth melt, but use what you have on hand.
- How do I store and reheat leftovers?
Wrap leftovers tightly and refrigerate for up to three days. Reheat uncovered on a baking sheet at 325°F for about ten minutes to bring the tops back to a crunch.
- Can I freeze French dip sliders?
Freeze assembled but unbaked sliders for up to one month. Bake from frozen, covered, adding an extra five minutes before uncovering.
