How to Freeze Garden Vegetables
By: Dan Aiston
If your garden has produced more vegetables than you can eat or know what to do with, you may want to consider freezing the excess harvest in order to enjoy your hard work later on in the year. Most garden veggies can be frozen and will keep well if stored properly in airtight containers. When freezing veggies always start with the highest quality of your yield to ensure best results and you will also need to blanch most veggies using boiling water or steam before loading up your freezer.
Preparing the Veggies
- Select young, freshly picked veggies. Garden veggies that have already been sitting out for several days will lose some of their freshness, and freezing may cause them to lose additional flavor. To ensure that the vegetables stay fresh for as long as possible, choose vegetables that are just barely ripe or slightly unripe. Steer clear of overripe veggies which may go bad even when frozen.
- Avoid veggies with blemishes, bruises, and soft spots. If you do use damaged garden veggies, remove these damaged spots before beginning the process.
- Wash your vegetables. Even if the garden they came from is organic and free of potentially harmful pesticides, they will still be covered in dirt and bacteria. If necessary, use a potato brush to gently scrub away any stuck-on grime.
- Cut up your veggies. Remove any non-edible parts and chop the veggies into your preferred size for eventual serving.
- Fill a large pot with at least 1 to 2 gallons of water. A blancher pot, which holds 6 to 8 quarts of water and contains a perforated basket for holding food works best, but any large pot that comes with a lid will also work.
- Boil the water over high heat. The water should reach a full boil before you add your veggies.
- Place 1 lb of your prepared veggies into a metal steaming basket. A wire-mesh strainer or cheesecloth may also work.
- Lower the veggies into the water. Make sure they are completely immersed.
- Cover your pot with a lid. Boil the veggies for as long as necessary according to expert boiling times. These do vary. For instance, cut corn takes 5 minutes while asparagus takes only 4.
- Remove the veggies from the pot and immediately transfer to large container of ice water. By shocking the veggies with ice water, you halt the cooking process and preserve the color of the veggies. Keep the veggies in the cold water for the same amount of time as you boiled them. Water must be at least below 60 degrees Fahrenheit and use approximately 1 pint of water for each pound of veggies.
- Drain veggies completely.
- Boil 1 to 2 inches of water in large pot. You need a pot that has a lid and fits an interior rack. The rack must be positioned 3 inches or more above the bottom of the pot.
- Place a single layer of prepared veggies in a steaming basket or cheesecloth bag. Do not pile the veggies so the steam can be evenly distributed. Asparagus, broccoli, and chili peppers do the best using this method.
- Set basket onto rack. Cover the pot and continue heating for as long as necessary for each veggie.
- Remove veggies from the pot. Shock veggies by transferring to ice bath. Allow ice bath for as long as steam.
- Drain veggies completely using strainer or large pasta drainer.
Packing and storing
- Lay blanched, drained veggies flat on shallow tray. Veggies should be arranged loosely in a single layer and should not overlap.
- Place the tray in the freezer. Wait until the veggies are firm before removing tray.
- Fill freezer bags or freezer containers with frozen veggies. You must leave an appropriate amount of empty space to allow food a chance to expand as it freezes.
- Label each bag/container with a felt tip marker. Write down the contents of the package and the date food was frozen.
- Place the sealed, labeled packages into your freezer. For best results, only pack 2 to 3 pounds of veggies for each cubic foot. If the veggies are packed any tighter than that, they may take too long to freeze.
- Keep the temp of your freezer set at 0 degrees Fahrenheit. The majority of garden veggies will retain their freshness, taste, and nutritional value for a year or longer if kept at this temperature.
- Start with easy-to-freeze veggies if you are new to the process. These include green beans, carrots, peas, peppers, squash, and sweet corn.
- If freezing your garden veggies goes well, consider freezing fruits as well. Most fruits freeze well, especially those in the berry family.
- Make sure to look up the exact recommendations for each garden veggie before blanching and packing. Each veggie has its own specifications concerning selection, preparation, blanching method, blanching time, and packing method. Under-blanching may stimulate the enzymes inside the veggies, causing them to decay. Over-blanching may cause your fresh garden veggies to lose nutritional value and flavor.
- Avoid freezing garden veggies that are almost always eaten raw, like celery, lettuce, and cucumbers. These veggies do not survive the blanching and freezing process well. However, veggies that can either be eaten raw or cooked, like carrots, do very well in the freezing process.
