Without a doubt, yes, you can freeze asparagus! Freezing seasonal produce is the easiest preservation method you can do at home.

In this article, we share the nitty-gritty of freezing asparagus, using frozen asparagus, and everything in between. So, keep reading!

The Best Way to Freeze Asparagus

Before we go further to the practical details of freezing asparagus, it is worth mentioning that raw vegetables don’t freeze very well—asparagus is one of them.

Raw vegetables contain enzymes that cause loss of flavor, color, and texture. You need to at least cook or blanch raw asparagus to inactivate these enzymes for long term storage. (*)

Perhaps, you’re asking whether you can freeze asparagus without blanching? Blanching is highly recommended before freezing raw vegetables. Without blanching, frozen asparagus won’t preserve its flavor and color and lose its texture during freezing.

Check this step-by-step guide on how to freeze fresh asparagus. (*)

1. Selecting the asparagus

If you forage wild asparagus, pick before the buds start to open. Otherwise, the spears turn woody and tough.

Choose only young, tender spears to freeze. The spears should be fresh, green, and firm.

2. Washing, sorting, and chopping asparagus

Wash each spear under running water. Get rid of any dirt, sand, and other particles.

Trim the bottom end of each spear that is woody and tough.

Next, you can chop the spears into 2 to 3 pieces or freeze as whole spears.

Sort the asparagus spears into three groups—small, medium, and large. Different sizes require a certain amount of blanching time. Skip this step if the stalks come in a uniform size.

3. Blanching the asparagus

Blanching is a crucial step in freezing vegetables. Improper blanching may ruin the vegetables during freezing.

Prepare one pot filled with water and bring to a boil. In the meantime, prepare another pot (or bowl) filled with ice and cold water.

When the water is boiling, place the chopped spears into the pot. Boil small stalks for 2 minutes, while the medium and large ones need 3 and 4 minutes, respectively.

Instead of boiling the asparagus, you can also steam them. Steaming takes 1 ½ time longer than water blanching. (*)

Use a timer to measure the time precisely and prevent under- or overcooking.

Next, remove the boiled asparagus and transfer it to the icy bath. Let them cool promptly for 3 to 4 minutes.

Drain the blanched asparagus in a colander and pat dry with a kitchen towel. Make sure they are thoroughly dry to prevent ice crystals from forming during freezing.

4. Flash freezing

Spread the prepped asparagus stalks on a baking sheet. Place them in the freezer for a couple of hours.

This step is optional but useful to prevent the stalks from sticking together when frozen. Proceed to the next step if you want to skip this one.

5. Freezing for long term

Pack the (frozen) stalks in a freezer-safe container or a freezer bag. Spread them evenly. If possible, pack an individual serving size.

Squeeze as much air as possible from the freezer bag and seal it tightly.

Label the bag with a freezing date and place it in the freezer for long term storage.

Frozen foods should be maintained at 0 °F (−18 °C) or lower. Make sure to check your freezer’s temperature and set it to 0 °F.
