🍔 Ingredient notes
- Rolls - Sweet hawaiian rolls add great flavor to these roast beef sliders. You can also use regular dinner rolls or slider buns if you don't want the added sweet flavor.
- Roast Beef - Get thinly shaved deli roast beef to make these oven baked sliders easily. You can also use leftover roast beef that you cut thinly on your own.
- Cheese - Provolone cheese adds a mild flavor that pairs well with the onions, roast beef and hawaiian rolls. Swiss cheese, gouda, white cheddar cheese or pepper jack would be other great options.
- Toppings - In addition to the caramelized onions and provolone cheese, the rolls are then topped with melted butter that is seasoned with garlic powder and dried onion. For a more plain sandwich, this topping can be omitted.
📋 Substitutions and variations
- Extra Toppings - Feel free to add extra toppings to the sandwiches if you like. Hot or sweet peppers, pickles or spicy mustard would be great additions.
- Gluten Free - Use your favorite gluten free rolls.
- Dairy Free - Replace the cheese and butter with dairy free alternatives.
🔪 Step by step instructions
First, make the parmesan black pepper mayo by whisking the mayo, parmesan cheese, garlic powder, pepper and salt together in a small bowl.
In a skillet, heat the butter over medium heat until it melts. Add the sliced onions with the red wine vinegar, salt and pepper. Saute the onions for 10-12 minutes until they are softened and slightly caramelized.
While the onions are cooking, slice the hawaiian rolls in half evenly through the middle so you have an even top and bottom layer.
Place the bottom buns in a greased 9x13 baking dish or on a baking sheet. Spread the parmesan black pepper mayo evenly over the cut side of the bottom buns.
Pile the roast beef slices evenly over the mayo mixture and then spread the caramelized onions on top.
Layer the provolone cheese over the top of the onions and add the top buns as the final layer.
In a small saucepan, melt the butter over low heat with the garlic powder and onions. Let the mixture simmer until it's fragrant and lightly browned.
Pour the butter topping over the buns and use a pastry brush to evenly distribute the mixture all over the buns.
Cover the baking dish with aluminum foil and bake at 350˚ for 20 minutes. Remove the foil and bake another 10 minutes until the sandwiches are lightly browned and the cheese is melted.

⭐ Expert tips
- Slice the onions thinly so they caramelize evenly and quickly. Make sure to stir them occasionally so they do not stick to the bottom of the pan and burn.
- Use a serrated knife to easily slice through the rolls. Place a hand on top of the rolls to make sure the rolls stay in place while you are slicing them.
- Instead of placing the roast beef in slices on the bread, separate the slices and place in them in little piles.
- Use a pastry brush to help spread the butter mixture over the entire tops of the rolls.
- If you like the buns to be a little bit more crunchy turn on the broiler for a couple of minutes at the end of baking.
- Before serving, use a knife to cut around the individual rolls for easy serving.
⏲️ Make ahead instructions
The roast beef hawaiian roll sliders may be assembled up to 24 hours ahead of time and stored in the refrigerator covered tightly in plastic wrap.
When you are ready to bake them, remove the plastic wrap and replace with foil. Baking times will be a bit longer since the sandwiches will be colder from storing them in the refrigerator.
🥡 Storage suggestions
These delicious roast beef sliders will keep in an airtight container in the refrigerator for 3-5 days and can easily be reheated in the microwave or in the oven.
