1. Cool It
Let food cool completely before freezing. If you freeze it when it’s warm, it produces excess moisture; the moisture freezes and turns into ice. Plus, putting hot food into the freezer can also partially thaw other food around it.
2. Wrap It
The best way to store food in the freezer is in vacuum-sealed bags or containers—removing all the air prevents moisture loss and keeps food from getting icy. The next best choice is to tightly wrap with heavy-duty foil or freezer paper.
3. Label It
A freezer stocked with ready-to-go dinners does you no good if you don’t know what’s in there. Label and date everything that you freeze. If you’re really organized, make an “eat-by” note on your calendar. Eat properly wrapped food within 3 to 6 months of freezing. Vacuum-sealed food will stay fresh for at least 1 year and sometimes up to 2 years.
