Set your oven to 350°F. Line your baking pan with parchment paper for easy cleanup.
Slice the Hawaiian rolls in half horizontally, keeping the top and bottom sections intact. Place the bottom halves on the prepared pan.
In a large mixing bowl, stir together the shredded chicken, cheddar cheese, buffalo sauce, ranch dressing, salt, and pepper. Mix until every piece of chicken is coated.
Spread the buffalo chicken mixture evenly over the bottom buns. Sprinkle green onions on top, then add the top halves of the rolls.
Melt the butter in a small bowl (about 10 seconds in the microwave). Stir in the ranch seasoning mix until well blended.
Brush the butter mixture over the tops of the buns. Cover the pan loosely with foil and bake for 15–20 minutes. Remove the foil and bake for an additional 5 minutes, or until the tops are golden and slightly crisp.
Notes
Make-Ahead Tip: Assemble the sliders (without the butter topping), cover tightly, and refrigerate up to a day in advance. Add the butter mixture right before baking.
For Crispier Tops: Remove the foil during the last 5–7 minutes of baking to let the rolls brown nicely.
Feeding a Crowd: Double the recipe and use two pans—these go fast!
For Milder Flavor: Use less buffalo sauce or mix half buffalo and half barbecue sauce for a toned-down version.
Quick Cleanup: Line your pan with both parchment and foil to catch any melted cheese or sauce drips.
