How to Blanch Green Beans

Blanching is a cooking method often referred to as “blanch and shock.” First you boil water, then place the green beans in for a couple of minutes, and finally move the green beans to a bowl of ice water to “shock” or stop the cooking process. 

Before you begin blanching you will want to wash and trim your green beans. I rinse mine in a colander under cold water and then shake to dry. As for trimming, you (or your kids) can snap off the hard ends by hand or you can cut them with a knife. 

It is such a simple method but it makes a huge difference in the overall quality and taste of the green bean. 

What is the purpose of blanching?

There a several reasons for blanching. When you blanch a vegetable if brightens the color. This is especially good for green vegetables like broccoli or green beans. Blanching removes any bitter taste from vegetables. Blanching also affects the texture. When you blanch green beans you end up with a very crisp and tender bean. The blanch method is a tool used to preserve the nutrients in preparation for freezing vegetables. 

Frequently Asked Questions:

Do you salt water when blanching vegetables?

I salt the water when blanching green beans because it improves the taste and also helps the green beans maintain their color.

How long do you blanch green beans?

Once the water is boiling you will only blanch the green beans for 2-3 minutes depending on their size.

How to look for the best green beans?

When buying green beans you want to find firm, bright green beans that snap. Avoid any limp or discolored beans.

How do I freeze green beans?

Once you have blanched your green beans, arrange the beans on a sheet pan lined with parchment paper and place in the freezer. Once they are frozen, you can put the green beans in an airtight bag and enjoy them throughout the year.
