Cook the vegetables for a short amount of time in boiling water to stunt their ripening enzymes. Check out this master guide from Colorado State University for precise blanching times for a variety of vegetables. 3. Chill Throughly - Remove the vegetables from the boiling water and immerse in ice water until the temperature has fully come down. This may take as long as the veggies were immersed in boiling water -- don't rush it! 4. Pack Tightly - The way you package your vegetables for freezing can make or break the finished product. We recommend the tray method of spreading veggies on a sheet tray until frozen solid, and then transferring to a heavy plastic bag or other container. 5. Thaw Within a Year - Frozen veggies don't last indefinitely and while they won't become toxic if you forget the zucchini in the back of your fridge for 2 years, the thawed result won't taste as good as if you used it sooner. Do you have any tips or best practices for freezing vegetables? What do you freeze?
