Method
Preparation
Cook the chicken by your preferred method—boil, bake, or use rotisserie chicken.
Preheat your oven to 350°F (175°C) and grease a 9x13 inch baking pan.
In a mixing bowl, add the cooked chicken and shred it with a fork if necessary.
Incorporate 3/4 cup of the shredded cheese, garlic powder, and cream cheese. Mix well until combined.
Making the sauce
In a saucepan, melt the butter over medium heat, then stir in the flour and taco seasoning, cooking for about 1 minute.
Gradually whisk in 2 cups of chicken broth until smooth.
Add half a cup of the shredded cheese and cook over medium heat until the mixture thickens and starts to bubble.
Remove the pot from the heat and stir in the sour cream and diced chilies. Avoid bringing the mixture to a boil at this stage.
Assembly and baking
In each tortilla, spoon in some of the chicken cheese mixture, roll it up, and place it seam-side down into the greased baking dish.
Pour the sauce evenly over the enchiladas and top with the remaining shredded cheese.
Bake for 22 minutes, then switch to high broil for an additional 3 minutes to achieve a golden and bubbly cheese topping.
Notes
You can swap the chicken with shredded pork or beef for a different flavor. For a vegetarian option, try using black beans or sautéed vegetables. Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, simply place them in a preheated oven until heated through.
