Bring a large pot of salted water to a boil and cook the chicken breasts until the internal temperature reaches 165°F.

Preheat the oven to 350°F and prepare a 9x13 inch baking dish with cooking spray.

In a saucepan, combine cream cheese, ranch dressing, Frank's RedHot sauce, black pepper, garlic powder, and onion powder, cooking until smooth.

Remove from heat, then add shredded chicken, 1 cup each of mozzarella and cheddar cheese, and most of the green onions; mix well.

Transfer the mixture to the baking dish, smooth it out, and layer with remaining mozzarella and cheddar cheese on top.

Bake for 20-30 minutes until bubbly and golden on top.

Broil on high for 2-3 minutes for a golden finish, watching closely to prevent burning.

Garnish with reserved green onions and serve with tortilla chips, veggie sticks or baguette slices.
