How To Freeze Thai Basil

There are three different ways of freezing Thai basil. Firstly, you can freeze it in freezer bags without blanching. Then you can freeze it in freezer bags with blanching. Finally, you can freeze it in ice cube trays.

Freezing Without Blanching

1. Wash and dry your Thai basil.

Put your Thai basil in a colander and rinse under a cold tap. Don’t use the hot tap as you don’t want to cook the Thai basil. When you have done this, put the basil on a paper towel and then pat it dry. Transfer the leaves onto another paper towel and leave for a few minutes until they are completely dry. You don’t want to put damp Thai basil in the freezer as this can cause ice crystals to form and this will make the basil go soggy when defrosted. 

2. Put the Thai basil on a baking tray.

Line the baking tray with greaseproof paper and place the Thai basil leaves on the tray. Make sure that they are not touching so that they don’t stick together when you bag them up. Then you will be able to take out just as many leaves as you need and not waste any. Freeze the Thai basil for about 12 hours.

3. Transfer the Thai basil into freezer bags.

Once the Thai basil leaves are frozen, take them out of the freezer and put them into a freezer bag. Make sure that you squeeze out all the air from the bag otherwise freezer burn may occur. The Thai basil will still be safe to use but it might lose taste and texture. Put a label on the bag with the date you put it in the freezer and what it is. If you freeze a lot of herbs this is very useful as you might not be able to tell what is in the bag.
