Unfortunately, Asparagus is seasonal, meaning you cannot buy it fresh throughout the year. 

Do not worry, because there is a way to store and preserve Asparagus once the season gets over. Of course, frozen Asparagus is nowhere as good as new Asparagus. However, what else can you do if you can not buy it fresh? This article will tell you all about freezing Asparagus the correct way so that it retains all the deliciousness.

How To Freeze Asparagus? A Step By Step Guide


Can You Freeze Asparagus?

The short, straightforward answer to this question is a yes. You can freeze Asparagus quickly and easily without a lot of effort. However, the freezing process requires precision and patience. Once you eat Asparagus for the first time, you can not get enough of it. If you have bought too much Asparagus, consider freezing it all! Freezing it can help you satisfy those cravings after the Asparagus season ends.

When Not to Freeze Asparagus?

  • If the Asparagus tips appear yellow or black, it is best not to freeze them. The yellow color indicates that the Asparagus is old. However, the dark green, almost black color, means that it is spoiled. Neither of them is ideal for freezing. Because their shelf life has already decreased to the most extent, there is no point in freezing them. 
  • If the Asparagus has wrinkles or slime, chuck it in the bin. It has already spoiled, and you can not eat or freeze it. Always use the freshest Asparagus for freezing to give them the best chance of preservation. 
  • If you have purchased pre-packaged Asparagus and it has surpassed the expiry date, do not freeze it. Pre-packaged Asparagus is not as good as fresh Asparagus. When it expires, it is of no use. It might look fresh and new to you, but it is older than you think. 

The rule of thumb while freezing Asparagus is to use it fresh. Spoiled, off-tasting, discolored Asparagus is not ideal for freezing. Why expend all that effort for preserving something old instead of new? If the Asparagus is old but not spoiled, use it in some salad or pasta immediately. If you want to preserve it at all, keep it in a jar of water in the fridge. That will increase its shelf life for a day or two.
