Place chicken and vegetables in a 9 x 13-inch baking dish that has been sprayed with cooking spray. Drizzle with oil, sprinkle with herbs and salt, and toss to coat.
Cover tightly with plastic wrap and foil; freeze until ready to bake.
When ready to bake, thaw dish in refrigerator overnight.
Remove the cover and bake in a 375-degree oven for 1 hour. Check to see if the chicken is cooked through. Return to the oven, if necessary, until chicken is done and vegetables are tender.
