Here is a list of freezer cooking supplies we also refer to frequently. The obvious ones are ziploc bags and disposable foil pans. Any reliable freezer-safe disposable bag brand will do. Also, depending on the freezer meal (like our zucchini lasagna recipe), the disposable aluminimum foil pans work great. We love the freezer bag stands too and wouldn't do a freezer cooking day without them! You use these bag stands to hold the bag upright making it much easier to place ingredients into the bag as you go.
