In a large mixing bowl, combine the shredded cooked chicken, softened cream cheese, sour cream, garlic powder, onion powder, and half of the shredded Monterey Jack cheese. Using a spatula, mix thoroughly until the ingredients are well blended and creamy. Season with salt and pepper to taste.
Preheat your oven to 350°F (175°C) and lightly grease a 9x13-inch baking dish to prevent sticking.
Take one flour tortilla and place it on a clean surface. Spoon a generous amount of the creamy chicken mixture into the center of the tortilla. Carefully roll the tortilla up tightly, ensuring the filling is enclosed. Place the rolled tortilla seam-side down in the prepared baking dish. Repeat this process with the remaining tortillas and filling.
Once all tortillas are in the baking dish, evenly pour the green salsa over the top, ensuring all enchiladas are covered.
Sprinkle the remaining shredded Monterey Jack cheese over the enchiladas as a delightful topping.
Bake in the preheated oven for 25-30 minutes, or until the cheese is melted, bubbly, and golden.
Remove the baking dish from the oven and allow it to cool for about 5 minutes, making it easier to serve.
Just before serving, garnish the enchiladas with fresh cilantro and sliced jalapeños for an extra kick if desired.
Notes
