Ingredient Notes

For exact ingredient amounts and full instructions, see the printable recipe card below.

• Hawaiian Rolls: Hawaiian rolls stay soft and buttery while balancing the savory roast beef and caramelized onions perfectly. You can also use my Buttery Bread Machine Rolls.
• Roast Beef: Thinly shaved deli roast beef works best for these sliders and layers easily onto the rolls.
• Smoked Cheddar Cheese: Adds a rich, smoky flavor that pairs perfectly with the caramelized onions and roast beef. Freshly grated cheese melts best.
• Onions: Sweet onions or yellow onions work great and become rich and flavorful once caramelized.
• Worcestershire Sauce: Adds extra savory flavor to the onions and gives these sliders even more depth.

Variations & Substitutions

• French dip style: Serve with warm au jus or beef broth for dipping.
• Add mushrooms: Cook mushrooms with the onions for extra flavor.
• Switch up the cheese: Try Provolone, Swiss, Mozzarella, Havarti, Gouda, or Gruyere. Gruyere cheese gives these sliders a more classic French onion flavor.
• Use ground beef: Swap the roast beef for cooked ground beef.
• Make them spicy: Add jalapenos or use pepper jack cheese.
• Change the topping: Sprinkle sesame seeds, fresh thyme, or Everything Bagel seasoning on top before baking.

How to Make French Onion Beef Sliders

Step 1. Preheat oven to 350 degrees. In a skillet, melt 1 tablespoon butter over medium-low heat. Add onions and cook until softened and caramelized. Stir in Worcestershire sauce and set aside.

Step 2. Slice the Hawaiian rolls in half horizontally and place the bottom half onto a large baking sheet. Layer the roast beef evenly over the rolls, followed by the caramelized onions.

Step 3. Sprinkle the grated cheese evenly over the onions, then place the top half of the rolls on top to create the sliders.

Step 4. Melt the remaining butter in a microwave-safe bowl and brush over the tops of the rolls. Sprinkle with garlic powder, onion powder, and seasoning, then loosely cover the baking sheet with aluminum foil.

Step 5. Place the baking sheet into the preheated oven and bake for about 15 minutes, or until the cheese is melted and the sliders are heated through.

Step 6. Remove the foil and bake an additional 5 minutes, or until the tops are golden brown. Remove from oven and serve warm. Enjoy!

Tips

• Cook the onions low and slow for the best caramelized flavor.
• Freshly grated cheese melts smoother than pre-shredded cheese.
• Covering the sliders with foil helps keep the Hawaiian rolls soft while baking.
• Don't overbake or the bottoms of the rolls can become too crispy.
• For extra flavor, brush a little extra butter on top before serving.
• Let the sliders rest for 2-3 minutes before serving so the cheese stays inside the sandwiches better.

Serving Suggestions

Serve these sliders with Ultimate Potato Salad, Crispy Parmesan Potatoes, or French Onion Rice for an easy comfort food meal everyone will love. Hosting a party or game day gathering? Pair them with Fried Pickle Dip, chips, and your favorite appetizers!

Storage & Reheating

• Store leftover sliders in an airtight container in the fridge for up to 4 days.
• Freeze for up to 3 months and thaw overnight before reheating.
• Reheat in the oven or air fryer at 350 degrees until warm and melty. The microwave works too, but the rolls will be softer.
