We love using homemade chicken seasoning, but any store-bought variety will work just as well. Be aware that the salt content can differ between brands, so it's a good idea to taste a bit of the seasoning beforehand to ensure it's adequately salted. If necessary, add extra salt to the chicken. Chicken thighs can range in size from 5 to 10 ounces; the given cooking time is based on 6-ounce thighs. Larger thighs may require additional time in the oven. Leftover chicken can be stored in an airtight container in the refrigerator for up to 5 days. Alternatively, you can freeze the cooked and cooled chicken thighs for up to 4 months.
