Question: how long to cook thawed chicken breast at 350?
Answer: Thaw frozen chicken slowly in your refrigerator, or thaw it faster by putting it in a leak-proof package or plastic bag and submerging in cold tap water. Bake a 4-oz. chicken breast at 350°F (177˚C) for 25 to 30 minutes. Use a meat thermometer to check that the internal temperature is 165˚F (74˚C).
