Creating delicious Ranch Chicken Enchiladas is straightforward if you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C).
2. Mix Filling: In a large bowl, combine the shredded chicken, ranch dressing, cream of chicken soup, garlic powder, onion powder, diced green chilies, and half of the cheddar and Monterey Jack cheese. Mix well until all ingredients are combined.
3. Prepare Tortillas: If your tortillas are stiff, microwave them for about 15 seconds to make them pliable.
4. Fill Tortillas: Spoon a generous amount of the chicken mixture into the center of each tortilla. Roll them up and place seam-side down in a greased 9×13-inch baking dish.
5. Top with Cheese: Once all tortillas are in the dish, sprinkle the remaining cheddar and Monterey Jack cheese evenly over the top.
6. Bake: Cover the baking dish with aluminum foil and bake in the preheated oven for 20 minutes. Then, remove the foil and bake for an additional 10-15 minutes, until the cheese is bubbly and golden.
7. Serve: Once baked, remove from the oven and let it cool for a few minutes before serving.
