**Preheat Oven**: Preheat your oven to 350°F (175°C).
**Prepare the Filling**: In a large mixing bowl, combine the shredded chicken, 1 cup of the shredded cheese, sour cream, cream of chicken soup, garlic powder, cumin, and chili powder (if using). Stir until well combined.
**Layer the Casserole**: Spread a thin layer of enchilada sauce on the bottom of your 9x13 inch casserole dish. Place a layer of tortillas on top, tearing them if needed to fit the pan.
**Add the Chicken Mixture**: Spread half of the chicken mixture over the tortillas. Add another layer of tortillas, followed by a layer of enchilada sauce, and then the remaining chicken mixture.
**Top with Cheese**: Place a final layer of tortillas on top, pour over the remaining enchilada sauce, and sprinkle with the remaining shredded cheese.
**Bake**: Cover the casserole with aluminum foil and bake for 25 minutes. Then, remove the foil and bake for an additional 10 minutes, or until the cheese is melted and bubbly.
**Serve**: Let the casserole cool slightly before serving. Garnish with green onions and cilantro, if desired.
