These crowd-pleasing sliders feature thinly sliced roast beef warmed in seasoned beef broth, then layered with buttery caramelized onions and melted provolone cheese on soft slider buns. After a quick bake until golden and bubbly, they're served alongside the same aromatic broth for dipping. The combination of tender beef, sharp cheese, and savory dipping sauce creates that irresistible French dip experience in handheld form.
The smell of these sliders takes me back to my first apartment, where my friend Mark showed up with deli roast beef and a packet of rolls after we both had terrible days at work. We stood around my tiny oven watching the cheese bubble, dipping each bite into juice dripping down our wrists, and suddenly everything felt manageable again. Now they are my go-to for feeding a crowd because watching people hover around the platter, seconds disappearing between conversations, reminds me that good food fixes most moods.
Last winter I made these for a snow day gathering and my brother-in-law, who claims to dislike anything fancy, ate four while pretending he was just helping clean up. The next week he texted asking for the recipe, claiming his kids had begged him to make them. They are the kind of food that turns skeptics into believers.
Ingredients
- Roast beef: Thinly sliced deli beef absorbs the au jus beautifully without becoming tough
- Slider rolls: Brioche adds sweetness but standard potato rolls work perfectly
- Provolone cheese: It melts creamy and mild without overpowering the beef
- Yellow onion: Slowly cooking them down brings out natural sweetness
- Butter: Two tablespoons helps caramelize the onions properly
- Mayonnaise: A thin layer adds creaminess and moisture
- Horseradish sauce: Optional but cuts through the rich cheese
- Beef broth: The base of your dipping liquid
- Worcestershire sauce: Adds deep umami notes
- Soy sauce: Enhances the beef flavor subtly
- Garlic and onion powder: Build layers of savory flavor

Instructions

- Make the au jus:
- Combine broth, Worcestershire, soy sauce, garlic powder, onion powder, salt, and pepper in a separate pan, bring to simmer, then add beef for 2 to 3 minutes
- Prep the rolls:

- Layer it up:
- Spread with mayo and horseradish if using, then add warm beef, onions, and a slice of provolone to each

These have become my emergency contribution for every potluck and football Sunday because people literally lean in when I walk through the door with that warm beef and cheese aroma. Last month my neighbor texted at midnight asking for the recipe after tasting them at our block party.
Make It Ahead
Assemble everything on the baking sheet, wrap tightly with foil, and refrigerate up to 8 hours. Let them sit at room temperature while the oven preheats so they bake evenly.
Cheese Swaps
Provolone melts beautifully but Swiss adds a nutty sharpness that cuts the richness. Mozzarella makes them extra gooey while Gruyère feels fancy and tastes incredible with the onions.
Serving Ideas
Pair these with a crisp green salad with vinaigrette to balance the richness. Cut them into smaller bites for appetizers or keep them whole for a main course that feels substantial.
- Set out extra napkins because dipping gets messy
- Warm any leftover au jus for seconds because people will want it
- Double the recipe because twelve disappears faster than you expect
There is something deeply satisfying about food you can eat with your hands while talking, dipping, and reaching for just one more. These sliders turn any Tuesday into a celebration.
Recipe FAQs
- → What type of beef works best?
-
Thinly sliced deli roast beef is ideal—look for a quality cut like rare roast beef from the deli counter. The thin slices warm quickly in the broth and stay tender.
- → Can I prepare these ahead of time?
-
Yes, assemble the sliders completely and refrigerate for up to 4 hours. Bake just before serving, adding a few extra minutes if baking cold. Keep the au jus separate and reheat when ready to serve.
- → What cheese alternatives work well?
-
Swiss or mozzarella both melt beautifully and complement the beef. Gruyère adds a nutty richness, though it has a stronger flavor profile.
- → How do I store leftovers?
-
Store cooled sliders in an airtight container for up to 2 days. Reheat in a 180°C oven for 8-10 minutes. Keep au jus refrigerated separately and reheat on the stove before serving again.
- → Can I make the au jus more flavorful?
-
Add a splash of red wine or a teaspoon of Dijon mustard to the broth. Some cooks add a beef bouillon cube for extra depth, or include fresh thyme sprigs while simmering.
- → What sides pair well?
-
A crisp green salad with vinaigrette cuts through the richness. Roasted potatoes, coleslaw, or simple vegetable sticks also complement these sliders nicely.
