1. Blanching Method to Freeze Mushrooms

Blanching is a proven method to kill any bacterial contaminants and extend the shelf life of a substance by halting its enzymatic processes. Similarly, when you blanch mushrooms you are indirectly hindering their enzymatic degradation process.

Start by slicing or trimming the unwanted parts of the mushroom and soaking them in lemon water for a few minutes. Follow these time limits for soaking respective mushrooms- 5 minutes for whole, 3 min for sliced, and 3 ½ minutes for quarter or button ones.

Then, blanch them for a maximum of five minutes duration and lay them on a separate sheet to dry. Flash freeze these blanched mushrooms for three hours by lining them on a cookie tray lined with parchment paper.

Finally, shift them into freezer-safe bags or containers and freeze them for later use. This method primarily helps to get rid of bacteria like Salmonella that are a threat to the shelf life of mushrooms.

First things first, take a small brush that you would usually use to brush oil in cake tins. Clean mushrooms using this brush and remove any traces of soil and dust. Avoid washing mushrooms with water because they will turn extra mushy if you wash them with water.

Add 2 tbsp oil to a pan and heat the pan on a high flame. Add your mushrooms and cook them for several minutes till they are nicely cooked from all sides. Since you didn’t wash the mushrooms in the prior step, it will help you retain water-soluble vitamins like flavonoids. Turn off the flame once they turn golden brown.

Line these cooked mushrooms on a baking tray and freeze the tray for three hours, at least. Then take clean airtight bags or containers and place all the frozen chunks in these bags. Add labels to them specifying the date of freezing for future reference.


Lastly, place these bags in the freezer. Remember to remove any excess traces of air from these bags before freezing. Also, do not stack or stuff other things over the bags, or else the mushrooms will break apart. Do not skip the flash freezing step unless you want to lose the original flavor of the mushrooms.
