French Dip Sliders with Crispy Onions Recipe
Beef, melty provolone, and a crunch in every bite, with warm au jus for dunking.

French dip sliders with crispy onions are the one dinner in my house nobody negotiates about. Four girls, one husband, zero agreement most nights, and every single one of them shows up for these. Tender roast beef, melty provolone, a buttery Hawaiian roll, and a little cup of au jus for dunking. Then the crispy fried onions tucked under the top bun, which is the part that makes people ask what's in these.
Fifteen years in restaurants taught me one thing about a French dip: the jus is not a garnish. It's the whole point. A dry French dip is just a roast beef sandwich with ambition. So these get jus two ways, a quick dunk on the beef before it goes in the pan and a warm cup on the side.
The adults in my house add a little creamy horseradish on the side. The kids pretend it doesn't exist. Everybody wins. If you want to go low and slow, the crockpot French dip sliders method below turns a chuck roast into fall-apart beef and makes its own au jus while you're doing literally anything else.
Why You'll Love This Recipe
Dinner and the game day spread in one pan. Twelve sliders, one 9x13, about 40 minutes.
The crunch survives. Onions go in two rounds, so you still get crisp after the cheese melts.
No soggy bottoms. A 5-minute pre-toast on the bottom buns keeps them sturdy enough to dunk.
Two ways in. Deli roast beef for weeknights, crockpot chuck roast when you want it shreddy.
Grown-up option on the side. Light horseradish cream for the adults, nothing weird on the kids' plates.

Ingredients for French Dip Sliders
Sliders
1 (12-count) package Hawaiian sweet rolls, kept connected (savory butter rolls work too)
1 lb thinly sliced deli roast beef, ask for it shaved thin so it doesn't pull out in one bite
8 slices provolone (about 6 oz), Swiss or pepper jack also work
1 1/2 cups crispy fried onions, divided
Butter topping
4 tbsp salted butter, melted
1 tsp Worcestershire sauce
1/2 tsp garlic powder
1/2 tsp dried parsley
Au jus
1 (1 oz) packet au jus gravy mix
2 cups water
1 tsp Worcestershire sauce
Creamy horseradish (optional, on the side)
1/2 cup sour cream
1 to 2 tbsp prepared horseradish, start light
1 tsp lemon juice
Pinch of salt
How to Make French Dip Sliders with Crispy Onions
Heat the oven. Heat to 350°F. Line or lightly grease a 9x13 baking dish.
Make the jus. Whisk the au jus mix, water, and Worcestershire in a small saucepan. Simmer over medium, stirring, 3 to 5 minutes until slightly thickened. Keep warm on low.
Toast the bottoms. Slice the rolls in half as one slab with a serrated knife. Set the bottom slab cut side up in the dish and bake 5 minutes, until the surface feels dry and just starts to turn golden.
Dunk the beef. Loosen the roast beef into ruffles, dip it in about 1/4 cup of the hot jus, and let the excess drip off. Damp, not dripping.
Build the sliders. Layer 4 provolone slices on the toasted bottoms, then the beef, the remaining 4 slices, and 1 cup of crispy onions. Add the top slab.
Brush the tops. Stir the melted butter with Worcestershire, garlic powder, and parsley. Brush it all over the tops.
Bake covered. Cover with foil and bake 12 minutes, until the cheese is melted at the edges.
Crisp the tops. Uncover, scatter the remaining 1/2 cup onions over the top, and bake 5 to 7 minutes until the tops are deep golden. Watch the last 2 minutes closely.
Stir the horseradish cream. While the sliders bake, mix the sour cream, horseradish, lemon juice, and salt. Chill.
Rest and serve. Rest 3 minutes, cut along the roll lines, and serve with cups of warm jus and horseradish cream on the side.
Crockpot French Dip Sliders Method
2 1/2 to 3 lb boneless chuck roast, seasoned with 1 tsp kosher salt and 1/2 tsp pepper
1 yellow onion, sliced
1 (1 oz) packet au jus gravy mix
2 cups low-sodium beef broth
1 tbsp Worcestershire sauce
Set the seasoned roast on the sliced onion in a 6-quart crockpot.
Whisk the au jus mix, broth, and Worcestershire and pour it over the roast.
Cook on LOW 8 to 9 hours or HIGH 5 to 6 hours, until the beef shreds easily with a fork.
Shred the beef. Strain the cooking liquid and skim the fat. That's your au jus, so skip Step 2 above.
Use about 3 cups of shredded beef, drained well, in place of the deli beef at Step 4 and bake as written. Leftover beef freezes beautifully.
Food Safety Note
Heat deli roast beef until steaming hot (165°F), which USDA recommends for deli meats if you're serving anyone pregnant, older, or immunocompromised. Chuck roast is safe at 145°F with a 3-minute rest, but it won't shred until well past that. For a party spread, keep the jus and beef at 140°F or above, and don't leave sliders or horseradish cream out more than 2 hours (1 hour above 90°F).
What I Tested
Pouring the jus over the whole pan, like a lot of versions do, turned the bottom buns into bread pudding, so now only the beef gets dunked and the bottoms get a 5-minute toast. Putting all the onions on top at the start burned them before the cheese melted, and putting them all inside made them soft, so they go in two rounds. The packet jus made with regular beef broth plus extra Worcestershire was salty enough to make your eyes water. Water for the packet version and low-sodium broth for the crockpot version fixed it.
Variations and Swaps
Slow cooker French dip sliders: Use the crockpot method above for shreddy, fall-apart beef.
Homemade au jus without a packet: Simmer 2 cups low-sodium beef broth, 1 tsp Worcestershire, 1 tsp soy sauce, and 1/2 tsp onion powder for 5 minutes.
Cheese swap: Swiss for classic French dip, pepper jack if you like a little heat.
Leftover pot roast sliders: Swap in 3 cups shredded leftover roast.
Spicy French dip sliders: Add sliced pepperoncini or giardiniera on top of the beef.
Tips
Shaved beef matters. Thick deli slices slide out of the bun in one bite and take the cheese with them.
Cut the slab first. Slice the whole package of rolls in half while connected. Separating them first is chaos.
Tent if needed. If the tops brown before the cheese melts, your oven runs hot. Re-cover with foil.
Party mode: Keep the jus in a small slow cooker on WARM so nobody gets a cold dunk in the third quarter.
Make ahead: Assemble through Step 5 up to 4 hours ahead and refrigerate. Brush the butter on right before baking and add 3 to 5 minutes.
Serving Suggestions
A jar of refrigerator bread and butter pickles cuts right through the richness.
Set them out with the rest of your game day appetizers.
On a cold night, start with a small cup of Mama's French onion soup.
Kettle chips or fries for the full diner situation.
Storage, Reheating, and Freezing
Storage: Refrigerate leftover sliders airtight up to 3 days. Store the jus and horseradish cream in separate containers, up to 3 days.
Reheating: Cover with foil and warm at 350°F for 10 to 12 minutes until hot in the center, uncovering for the last 2. Reheat the jus on the stove until simmering. The microwave works, but the onions go soft.
Freezing: Wrap assembled, unbaked sliders (without the butter topping or top onions) tightly and freeze up to 2 months. Thaw overnight in the fridge. Crockpot beef frozen in its jus keeps up to 3 months.
Frequently Asked Questions
Can I make French dip sliders ahead of time?
Yes. Assemble them through the cheese and top buns up to 4 hours ahead, cover, and refrigerate. Brush on the butter topping right before baking and add 3 to 5 minutes to the covered bake time since they start cold. Make the jus ahead too and rewarm it on the stove.
How do you keep French dip sliders from getting soggy?
Toast the bottom buns for 5 minutes before building, dunk only the beef instead of pouring jus over the pan, and put a layer of provolone on the bottom as a moisture barrier. Serve the rest of the jus on the side so each person dunks right before they bite.
What cheese is best for French dip sliders?
Provolone is our go-to because it melts smooth without getting greasy and has a mild bite that works with beef. Swiss is the classic French dip choice and a little nuttier. Pepper jack adds heat. Avoid pre-shredded cheese here, since slices melt more evenly across the pan.
How long do crockpot French dip sliders take?
The beef takes 8 to 9 hours on LOW or 5 to 6 hours on HIGH, until it shreds easily with a fork. After that, assembly and baking take about 30 minutes. The crockpot makes its own au jus from the cooking liquid, so strain it, skim the fat, and serve it warm.
Can I make au jus without a packet?
Yes. Simmer 2 cups low-sodium beef broth with 1 teaspoon Worcestershire, 1 teaspoon soy sauce, and 1/2 teaspoon onion powder for about 5 minutes. Taste before adding salt. For a slightly thicker jus, whisk in 1 teaspoon cornstarch mixed with a splash of cold water and simmer another minute.
What do you serve with French dip sliders?
Pickles, kettle chips, fries, or a crunchy slaw balance the rich beef and cheese. For game day, set them next to a couple of dips and a veggie tray. For dinner, a simple green salad or a cup of French onion soup turns them into a full meal.
