My French Dip Sliders were born from my love of the classic sandwich but I wanted something easier to share at parties. Now they're my go-to party food! The way those buttery rolls get toasted and crispy while holding juicy roast beef melty cheese and sweet onions is absolutely incredible. And that warm au jus for dipping? Pure magic!

Why These Are Always Gone First

These sliders are seriously addictive! They're like little bites of heaven combining everything we love about French dip sandwiches in a fun slider size. I love how easy they are to make ahead and they always disappear first at every gathering.

What You'll Need

  • Slider Rolls: Those Hawaiian ones work perfectly here.
  • Roast Beef: Get it sliced nice and thin.
  • Cheese: Swiss or provolone both melt beautifully.
  • Onions: Caramelized until they're sweet and golden.
  • Special Spread: My horseradish-mayo kicks things up.
  • Butter: For that amazing topping.
  • Seasonings: Garlic onion powder Worcestershire and parsley.
  • Beef Broth: Get the good stuff for your jus.

My Best Tips

Always toast those rolls first it makes such a difference. I keep caramelized onions in my freezer for quick prep. Spring for good roast beef and broth you'll taste the difference. That covered-then-uncovered baking method? That's how you get perfectly moist insides and crispy tops.

Mix It Up

Not a fan of horseradish? Dijon works great too. Sometimes I use cheddar for extra punch or add mushrooms for even more flavor. When I'm really pressed for time I use jarred au jus it's still delicious.

Keeping Them Fresh

If you have leftovers (which rarely happens!) keep the sliders and jus separate in the fridge. Wrap the sliders in foil to reheat them they'll taste almost like fresh-baked.

Perfect Party Food

Whether it's game day a casual get-together or just family dinner these sliders always hit the spot. We love them with crispy fries or a fresh salad on the side. Just make sure you make enough they go fast!

Frequently Asked Questions

→ Can I make these ahead?

Yes, assemble up to 24 hours ahead without butter topping. Add topping just before baking.

→ Why toast rolls first?

Pre-toasting helps prevent soggy bottoms and adds texture.

→ Why add flour to jus?

It gives body to prevent rolls from getting too soggy when dipping.

→ Can I use different rolls?

Hawaiian rolls provide ideal sweetness and texture, but other slider rolls work too.

→ What's the best cheese to use?

Both provolone and Swiss work well - provolone is milder, Swiss more tangy.
