how long should you cook chicken for?
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. Boneles â¦ s chicken will be done  in 30-40 minutes. I use Shake & Bake many times and it seals in the juices if the chicken is skinless and no bone. 2  The temperatures and how long you should cook it are on the box. 3  Place the chicken on slide aluminum foil on a cookie sheet.
