Preheat oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish.
In a large bowl, mix together shredded chicken, cream of chicken soup, sour cream, peas and carrots, cheddar cheese, garlic powder, and seasoned salt until well combined.
Cut each biscuit into four pieces.
Gently fold the biscuit pieces into the chicken mixture, making sure they are evenly coated.
Spread the mixture evenly into the prepared baking dish.
Bake for 35 minutes, or until the biscuits are cooked through and the casserole is bubbly and lightly golden on top.
Let rest for 10 minutes before serving.
Enjoy!
