The other night I threw the chicken breasts into the oven to cook up quick so that I could add them to the pasta. In 30 minutes, I had juicy, thoroughly cooked chicken breasts.
You could even cook up your chicken ahead of time if you're needing chicken for a cold pasta or cold salad. Cook the chicken, let it cool and cut/dice as needed. You'll still have flavorful, moist chicken! This would work great on a busy weeknight, too. While your chicken is cooking, prepare some veggies or a salad for a quick and delicious dinner.
Preheat your oven to 400*. Cover a rimmed baking sheet with two sheets of foil. Place your chicken breasts on the foil lined baking sheet. Sprinkle with whatever seasonings you desire on your chicken. Place a piece of foil over the top of the breasts, crimping around the edges of the pan so that you have created a completely covered baking sheet. Put the baking sheet in the oven for 30 minutes.
After the 30 minutes, check to make sure your chicken is done. If needed, cover with the foil again and cook an additional 15-20 minutes or however long you need until it's done.
