Easy Italian Chicken

Pour salad dressing into a large resealable plastic bag. Add chicken breasts, seal bag, and shake to coat. Marinate in the refrigerator for at least 1 hour or overnight (the longer you marinate, the more flavor the chicken will absorb).

Preheat the oven to 350 degrees F (175 degrees C).

Remove chicken from marinade and place in a lightly greased 9x13-inch baking dish; discard remaining marinade.

Bake in the preheated oven, turning chicken occasionally, until cooked through and juices run clear, about 1 hour. An instant-read thermometer inserted into the center should read at least 165 degrees F (74 degrees C).
