Preheat your oven to 425°F (220°C) and lightly grease a 9x13-inch casserole dish.

In a large mixing bowl, combine the shredded rotisserie chicken, cream cheese, shredded cheddar cheese, hot sauce, and ranch dressing until smooth.

In another bowl, whisk together the hot sauce, melted butter, garlic powder, onion powder, and cayenne pepper (if using).

Pour half of the prepared sauce mixture into the bottom of your greased casserole dish.

Scoop about 2 tablespoons of the chicken filling into the center of each tortilla, roll it up tightly, and place it in the prepared dish.

Drizzle the remaining sauce over the top and sprinkle additional shredded cheddar cheese.

Bake for 20-23 minutes until the cheese is melted and bubbly.

Let cool for a few minutes, then drizzle with ranch dressing and garnish with chopped green onions.
