1 Broil 4- to 5-ounce boneless, skinless chicken breasts 12 to 15 minutes, turning over about halfway through the cooking time and brushing with sauce or seasoning if desired. 2  Remove chicken when it reaches 170 degrees F and is no longer pink.
You should bake 2 lbs. of chicken breasts in the oven at 350  degrees for one hour if the chicken is on the bone. If the chicken  is boneless it will take less time. generally bake mine at 350 degrees for 35-40 minutes and then cut at the thickest point to see if the juices run clear. If you bake too long it becomes too dry. I always bake my thawed chicken breasts at 375 degrees for 50 min. and they come out juicy and fully cooked. The juices need to run clear.
