1. Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper for easy cleanup.
2. In a large bowl, combine the shredded chicken, buffalo sauce, melted butter, and ranch dressing. Stir until the chicken is evenly coated.
3. Place the bottom halves of the slider buns on the prepared baking sheet. Distribute the buffalo chicken mixture evenly over the buns.
4. Sprinkle the mozzarella cheese and crumbled blue cheese (if using) over the chicken mixture.
5. Place the top halves of the buns over the cheese, pressing down gently.
6. Brush the tops of the buns with olive oil and sprinkle with sliced green onions, salt, and pepper.
7. Cover the sliders with aluminum foil and bake for 15 minutes. Remove the foil and bake for an additional 5 minutes, or until the cheese is bubbly and the tops are golden brown.
8. Remove from the oven and let cool slightly before serving. Enjoy the sliders warm for the best experience!

These sliders are a breeze to prepare, and I love using rotisserie chicken to save time. It’s a little trick I picked up from my grandmother—make the most of what you have and let the flavors speak for themselves.
