French Dip Sliders tuck tender roast beef, soft onions and melted provolone into sweet Hawaiian rolls. A garlic butter topping gives the bread a golden finish. Warm au jus on the side adds a rich, savory dip without soaking the whole batch. Serve them for game day, a casual lunch or an easy dinner.
Why I Love This Recipe
There is plenty to like about a sandwich that bakes as one batch. The sweet bread balances the savory filling, and the dipping sauce makes each bite feel a little special. Thin deli roast beef also keeps the prep simple.
- Easy to share: Cut along the roll seams for small, neat sandwiches.
- Soft and toasty: Covered baking warms the filling before the tops get their golden finish.
- Dip when ready: Separate au jus keeps the bread from turning soggy.
- Simple ingredients: No roast to cook or gravy packet to track down.

How to Make French Dip Sliders
Cook the onion first so it adds flavor without leaving water in the bread.
Step 1: Soften the Onion
Melt 1 tablespoon unsalted butter in a skillet over medium heat.
Add 1 medium onion, thinly sliced, and 1/8 teaspoon ground pepper.
Cook for 12–15 minutes, stirring often, until soft, translucent and lightly golden. Lower the heat if the edges brown before the onion softens.
Step 2: Build the Sliders
Heat the oven to 350°F (175°C).
Grease a white 9×13-inch rectangular ceramic baking dish with 1 teaspoon unsalted butter; leave it unlined.
Slice 12 connected Hawaiian rolls horizontally into a bottom slab and a matching top slab. Set the bottom slab in the dish.
Spread 1 pound thinly sliced cooked deli roast beef evenly over the bottoms, folding it loosely rather than packing it down.
Divide all the cooked onion from Step 1 evenly over the beef.
Set 12 thin square provolone slices, totaling 6 ounces, over the onion, one slice per roll. Keep them separate, with no overlaps or doubled slices.
Replace the top slab so each upper roll sits over its matching bottom.
Step 3: Mix the Butter Topping
Melt 3 tablespoons plus 2 teaspoons unsalted butter in a microwave-safe bowl in short bursts.
Stir in 1 teaspoon Worcestershire sauce and 1/2 teaspoon garlic powder until well mixed.
Step 4: Butter and Bake
Brush all the butter topping from Step 3 evenly over all 12 roll tops, including the edges.
Cover the dish loosely with foil and bake for 20 minutes.
Remove the foil and bake for 5–10 minutes, until the tops are golden, every cheese slice is fully melted and the center is heated through. If the tops color too fast, loosely cover them again.
For a conservative reheating check with refrigerated cooked beef, aim for 165°F (74°C) in the center of the filling.
Sprinkle 1 tablespoon finely chopped fresh parsley evenly over every roll as soon as the dish comes out.
Rest for 5 minutes before cutting.
Step 5: Warm the Au Jus
While the sliders bake, put 1 1/2 cups low-sodium beef broth, 1 tablespoon Worcestershire sauce, 1/4 teaspoon garlic powder and 1/4 teaspoon onion powder in a small saucepan.
Bring to a gentle simmer over medium heat, then reduce the heat and simmer for 5 minutes. Keep it warm over low heat until serving.
The sauce should be thin and savory, rather than thick like gravy.
Step 6: Cut and Serve
Cut the rested batch along its seams into 12 sliders, keeping the top and bottom together.
Serve 2 sliders per person with about 1/4 cup warm au jus, divided from the prepared sauce, for a quick dip just before each bite.
For dinner, add a green salad or roasted green beans on the side.
Why This Recipe Works (Quick Science)
Thin slices of beef warm more evenly than thick stacks. Softening the onion first removes some moisture and gives it a sweeter taste. The covered part of baking traps warmth around the filling so the cheese can melt before the bread gets too dark.
The final uncovered bake dries the buttered tops a little, leaving golden bread with soft crumb underneath. Keeping the au jus separate matters too: bread absorbs thin liquid fast, so dipping at the table gives you more control over the texture.
Common Mistakes to Avoid
- Using wet onions: Cook away visible liquid before adding them to the bread.
- Packing the beef tightly: Loose folds let the filling heat through more evenly.
- Leaving cheese in thick stacks: Thin slices melt more readily and spread across each roll.
- Skipping the foil: The tops can brown before the middle warms.
- Pouring sauce over the batch: Save the au jus for individual dips.
- Cutting right away: A short rest helps the sandwiches hold together.
What to Serve With French Dip Sliders
Warm au jus is the key pairing. Put out small dipping bowls so everyone can dip as they eat. A crisp green salad balances the rich cheese and butter. Roasted green beans also make an easy dinner side. Keep those sides separate so the rolls stay dry until you choose to dip them.
Make-Ahead Tips
Cook the onions up to a day ahead and chill them in a covered container. Let them cool before assembling the sliders. Assemble the sandwiches, cover tightly and refrigerate for up to 24 hours. Add the butter topping just before baking. A chilled batch may need 5–10 extra minutes covered; check the center rather than relying only on the clock.
Leftovers and Storage
Refrigerate sliders and au jus in separate sealed containers within 2 hours of cooking. Use within 3–4 days. Reheat the sliders covered at 325°F (165°C) until the center reaches 165°F (74°C), then uncover briefly to refresh the tops. Warm the au jus separately and bring it to a boil before serving leftovers. Freeze wrapped sliders for up to 2 months for best quality; thaw in the refrigerator before reheating.

Frequently Asked Questions (FAQ)
Q: What roast beef works best?
A: Choose fully cooked deli roast beef sliced thin enough to fold. Very thick slices can make the small sandwiches hard to bite.
Q: Can I use leftover roast beef?
A: Yes. Slice it thinly against the grain and use the same weight. Trim any tough edges first.
Q: Can I use another cheese?
A: Swiss is a good swap. Use the same weight in thin slices that fit each roll.
Q: Do I have to use sweet rolls?
A: No. Soft plain slider rolls work too. Choose rolls close in size to the Hawaiian rolls so the filling ratio stays similar.
Q: Is au jus the same as gravy?
A: No. Au jus is a thin dipping liquid. This quick version uses beef broth for flavor and has no flour or cornstarch.
Q: Can I leave out the onions?
A: Yes. Skip the onion and its tablespoon of cooking butter. The roast beef and provolone still make a flavorful filling.
Q: Why are the centers cool when the tops are brown?
A: The bread may have browned before the filling warmed. Cover loosely with foil and keep baking until the center is heated through.
Q: Can I make a larger batch?
A: Double the ingredients and use separate dishes rather than piling more filling into one pan. Check each dish for doneness.
Q: How do I avoid soggy bottoms?
A: Cook excess moisture out of the onions, keep the au jus separate and avoid holding dipped sandwiches for later.
Final Thoughts
French Dip Sliders bring together soft bread, savory beef and a simple dipping sauce in a shareable bake. Keep the filling loose, let the cheese melt fully and dip each bite when you are ready. Leave a comment with your favorite side to serve alongside them. Happy cooking!
