Can You Freeze String Beans?

String beans are a firm favourite when they are in season and if you are growing these veggies in your garden then you probably find you can keep harvesting them for weeks. You can’t possibly eat them all so can you freeze string beans for later instead?

The Quick Answer

Yes, you can freeze string beans. String beans can be frozen for around 8 months. You do have to prepare and blanch them beforehand but they do freeze well and stay fresh tasting.

How to Freeze String Beans

Freezing string beans is fairly easy to do, but there is a little preparation work to do upfront. This is to blanch the beans first because if you try and freeze them raw, they may spoil in the freezer and not end up tasting quite as good.

Luckily, once you get the blanching process worked out, it’s easy to do, and you can freeze lots of vegetables that would usually spoil in the freezer the same way:

  1. Prepare Beans
    Trim and cut out your beans. You can cut them into smaller pieces to make them easier to use later. As you trim the beans, throw out any beans that show any signs of damage or spoiling. You only want to freeze the best quality string beans as this will ensure the best results.
  2. Wash
    Wash the beans in cool water and let them drain.
  3. Prepare for Blanching
    Next, you need to prepare for blanching. You need a saucepan of boiling water, a way to drain the beans and some ice water. To make the ice water, you can either put a bowl of water in the fridge to cool or pop some ice cubes into a bowl of water. The amount of water you need will depend on how many beans. You need approximately a gallon of water per pound of beans.
  4. Boil Water
    Pop the saucepan of water on to boil and make sure your ice water and equipment are nearby because you will need to move fairly quickly once the beans are boiling.
  5. Boil Beans
    When the water is boiling, put the string beans into the water and bring them back to the boil for about two to four minutes.
  6. Cool
    Once the time is up, you need to take the string beans out of the boiling water and plunge them immediately into the ice water and leave until they are cooled. This halts the cooking process and makes sure your beans are only par-cooked and not completely cooked.
  7. Drain
    Drain the beans from the water and allow them to dry.
  8. Freeze
    Next, you need to grab a baking sheet or flat freezer-safe dish. Put some parchment paper onto it, and then pour the string beans onto it. Make sure there is only a single layer of beans, and then put this into the freezer for about an hour.
  9. Bag Up
    Once the string beans are frozen, you can take them out of the freezer and transfer them into a freezer bag. Doing this extra step of freezing on a baking tray first allows you to be able to take out a portion of the string beans at a time and avoid them freezing together in a big clump.
  10. Freeze
    Label the bag with the date and contents and pop the bag into the freezer.

3 Tips for Freezing String Beans

Now you know how to freeze them, we’ve got our 3 top tips which we strongly recommend following when freezing string beans to have the best results:

  • Keep Them Airtight – When you are freezing your string beans, you want to keep them as airtight as possible so squeeze out the air before you pop the freezer bag into the freezer.
  • Consider Use – When cutting your beans, make sure you think about how you plan to use them. If you like to use them in smaller pieces for soups and stews, then cut them up this way before freezing. If you prefer to keep your string beans whole for stir fry and side dishes, then do this. It makes it much easier to deal with when you grab them out of the freezer, especially as you might be able to cook your string beans from frozen.
  • The Fresher, The Better – If you plan on freezing beans, try to freeze them as soon as you pick them. The fresher they are, when you freeze, the fresher they will taste when you thaw them out and cook them.
