Ingredient Spotlight

Hawaiian Sweet Rolls are Essential: King’s Hawaiian rolls provide the perfect sweet-savory balance and stay soft even after baking. Their slight sweetness complements the savory beef and creates that signature slider texture. Regular slider buns work but won’t have the same flavor.

Deli Roast Beef Quality: Ask your deli for thinly sliced rare roast beef so it doesn’t overcook during baking. The quality of your deli meat makes a huge difference—spring for the good stuff. Pastrami is also an excellent alternative that adds extra flavor.

Provolone Cheese Choice: Use mild, young provolone from the deli counter—not aged provolone which has sharper, funkier flavors. The mild version melts beautifully and provides creamy richness without overpowering the beef.

Au Jus Mix Convenience: While homemade au jus is amazing, packaged au jus mix delivers great flavor with zero effort. It’s the secret weapon that makes these party-ready in minutes.

Ingredients

For the Caramelized Onions:

2-3 tablespoons unsalted butter
1 large yellow onion, thinly sliced
¼ teaspoon sugar (helps caramelization)
¼ teaspoon salt
¼ teaspoon black pepper
2 teaspoons fresh thyme, minced (optional)

For the Sliders:

1 package (12 count) Hawaiian sweet dinner rolls
1 lb deli roast beef, thinly sliced (or pastrami)
10-12 slices provolone cheese (mild, not aged)
1½ cups crispy fried onions (optional but delicious)
¼ cup mayonnaise or Dijon mustard (for spreading)

For the Garlic Butter Topping:

½ cup (1 stick) unsalted butter, melted
1½ tablespoons dried onion soup mix (or au jus mix)
1 teaspoon Worcestershire sauce
¾ teaspoon garlic powder or minced garlic
½ teaspoon onion powder
1 tablespoon sesame seeds
1 tablespoon fresh parsley, chopped (for garnish)

For the Au Jus:

1 packet (1 oz) au jus gravy mix
3 cups water (or beef broth for richer flavor)
1 tablespoon Worcestershire sauce (optional)

Ingredient Notes:

Quality matters most: Use good quality deli roast beef—it’s the star ingredient
Room temperature is key: Let butter soften slightly before melting for easier mixing
Don’t skip: The garlic butter topping is what makes these special—don’t just use plain butter

Essential Equipment

You’ll Need:

9×13-inch baking dish — greased or buttered
Large skillet — for caramelizing onions
Small bowl — for mixing garlic butter
Serrated knife — for cutting rolls
Pastry brush — for applying butter topping

How to Make French Dip Sliders (Step-by-Step)

Step 1: Caramelize the Onions

In a large skillet over medium heat, melt 2-3 tablespoons butter. Add thinly sliced onions and ¼ teaspoon sugar, coating them in the butter. Cook, stirring occasionally, for 12-15 minutes until the onions are soft, golden brown, and caramelized but not burnt. Add thyme, salt, and pepper in the last minute of cooking. Remove from heat and set aside. The onions should be sweet, jammy, and deeply flavored.

Pro tip: Don’t rush the caramelization—those 12-15 minutes develop incredible sweetness and depth.

Step 2: Prep the Rolls and Pan

Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or cooking spray. Without separating the rolls, use a serrated knife to slice the entire sheet of Hawaiian rolls horizontally through the middle, creating a top and bottom half. Place the bottom half of the rolls in the prepared baking dish, keeping them connected as one piece.

Common mistake: Separating the rolls before cutting—keeping them connected makes assembly much easier.

Step 3: Layer the Fillings

Spread mayonnaise or Dijon mustard evenly over the bottom rolls. Layer half of the provolone cheese slices over the bottom, covering the entire surface. Add all the roast beef in an even layer, folding or layering slices to cover completely. Spread the caramelized onions evenly over the beef. If using crispy fried onions, add them now for extra crunch. Top with the remaining provolone cheese slices, making sure to cover all the beef. Place the top half of the rolls over the cheese.

Pro tip: Layer ingredients edge-to-edge so every slider has filling in every bite.

Step 4: Make and Apply Garlic Butter Topping

In a small bowl, combine melted butter, onion soup mix (or au jus mix), Worcestershire sauce, garlic powder, onion powder, and sesame seeds. Mix well until everything is combined. Use a pastry brush to generously brush the entire surface of the top rolls with the garlic butter mixture, making sure to get into all the crevices. Don’t be shy—use all the butter for maximum flavor.

Test kitchen discovery: The seasoned butter is what creates that addictive golden, crispy top.

Step 5: Bake Until Golden and Melty

Cover the baking dish with aluminum foil. Bake for 15 minutes covered to melt the cheese and warm the beef through. Remove the foil and bake for an additional 5-10 minutes until the tops are golden brown and crispy. The cheese should be completely melted and the rolls should be toasted on top. If the tops aren’t golden enough, broil for 1-2 minutes, watching carefully to prevent burning.

Pro tip: The foil prevents the tops from browning too quickly before the insides are hot.

Step 6: Make the Au Jus

While the sliders bake, make the au jus. In the same skillet used for onions (don’t clean it—those browned bits add flavor), add 3 cups water and bring to a simmer. Whisk in the au jus gravy mix packet according to package directions, stirring until smooth. Add Worcestershire sauce if using. Simmer for 5-10 minutes until slightly reduced and flavorful. Taste and adjust seasoning—you can add more au jus mix if it’s too mild. Keep warm until ready to serve.

Test kitchen discovery: Using the onion pan to make au jus adds incredible depth from the caramelized bits.

Step 7: Slice and Serve

Remove sliders from the oven and let rest for 2-3 minutes. Sprinkle with fresh chopped parsley if using. Use a sharp knife to cut through the natural divisions in the rolls, creating 12 individual sliders. Serve immediately with warm au jus on the side in small bowls for dipping. Each person can dip their slider into the au jus for that classic French dip experience.

Pro tip: Cut while still warm for easiest slicing—the melted cheese will hold everything together.

Expert Tips & Tricks

Temperature Matters: Make sure your oven is fully preheated to 350°F—this ensures even cooking and properly melted cheese. Too hot and the tops burn before the insides are warm.

Don’t Overbake: The sliders are done when the tops are golden and the cheese is melted, usually 20-25 minutes total. Overbaking dries out the rolls and toughens the beef.

The Secret to Extra Flavor: Add a thin layer of horseradish sauce or creamy horseradish to the rolls before adding beef for authentic French dip flavor. It adds a subtle kick that elevates everything.

Common Mistake: Using aged or sharp provolone—it doesn’t melt as smoothly and has overpowering flavors. Stick with mild deli provolone for best results.

Make-Ahead Magic: Assemble the sliders completely, cover tightly with foil, and refrigerate for up to 24 hours before baking. Add 5 minutes to the covered baking time.

Your Questions Answered

Can I use regular dinner rolls instead of Hawaiian rolls?
Yes, but you’ll miss the signature sweet flavor that makes these special. Hawaiian rolls are recommended for authentic slider taste, but any soft dinner rolls work in a pinch.

Do I have to caramelize the onions?
No, but they add incredible flavor. You can skip them for even faster prep, or use crispy fried onions only.

Can I make these without au jus?
Yes, but the au jus for dipping is what makes them “French dip” style. They’re still delicious without it, just more like regular roast beef sliders.

What other meats work besides roast beef?
Pastrami, corned beef, turkey, or ham all work wonderfully. Each creates a different flavor profile but the same great texture.

How do I prevent soggy sliders?
Don’t add too much mayo or mustard, and make sure your beef isn’t too juicy. The foil cover helps steam things perfectly without making them soggy.

Can I use Swiss cheese instead of provolone?
Absolutely! Swiss is traditional for French dip and melts beautifully. Mozzarella also works well.

How do I keep them warm for a party?
Keep covered with foil in a warm oven (200°F) for up to 1 hour. The au jus can stay warm in a slow cooker on low.

Recipe History & Cultural Context

French Dip Sliders are a clever modern adaptation of the classic French dip sandwich, which was invented in Los Angeles in the early 1900s. Two restaurants—Philippe the Original and Cole’s—both claim to have created the original French dip, though the exact origin remains deliciously disputed. The traditional sandwich features thinly sliced roast beef on a French roll, served with beef juice (au jus) for dipping.

The slider format emerged as party food and game day fare became increasingly popular in American culture. By baking a whole tray of connected Hawaiian rolls topped with savory butter, home cooks discovered they could serve a dozen sandwiches with minimal effort—no individual assembly required. Hawaiian sweet rolls, invented by Robert Taira in Hawaii in the 1950s, became the go-to choice because their soft, sweet texture contrasts perfectly with savory fillings.

French Dip Sliders embody everything we love about modern convenience cooking—taking a beloved classic and making it more shareable, more party-friendly, and easier to prepare while maintaining all the flavors that made the original famous. They’ve become a staple at Super Bowl parties, potlucks, and casual gatherings, proving that sometimes the best innovations are simply making great food more accessible to everyone.
