You absolutely can! You will just need a large enough container that will allow the turkey to be completely immersed in the brine. If you choose to brine your turkey, this will add extra moisture to the turkey and some extra flavor from the salt. If you choose to brine, you will want the turkey to brine for at least 8 hours. Keep in mind, the turkey has to be completely thawed before adding it to the brine or the brine won't be able to do its job. The basic turkey brine recipe is 4 quarts of water mixed with 1 cup of kosher salt.
