How to Blanch and Freeze Cauliflower

Fresh cauliflower florets

Freezing is the best way to preserve cauliflower. It doesn't dehydrate well, and loses nutrients and gets mushy if you pressure can it.

Giving the cauliflower florets a quick blanching in boiling water before freezing them ensures that they will retain a good texture when you get around to cooking with them.

The single layer initial freeze prevents the cauliflower florets from clumping together. The fact that they stay loose is a big advantage when, for example, you have a quart container of frozen cauliflower but only need to take out a cup of it for a recipe.

Here are the easy steps for freezing cauliflower:

Clean and Cut into Florets

Soak the whole cauliflower for a few minutes in water to get rid of any dirt or garden bugs. Remove the green parts. Chop the whole cauliflower head in half. Cut out the solid stem section. After that you can break the florets apart by hand, but use a knife to cut big florets into smaller ones no more than 1 1/2-inches thick.

While you are preparing the cauliflower, have a pot of water coming to a boil on the stove. Also get a big bowl of ice water ready.

Blanch

Once the cauliflower is separated into florets, drop the florets into the pot of rapidly boiling water. Let them cook for 5 minutes. Drain the cauliflower in a colander. You can also steam the cauliflower for 5 minutes rather than boiling it.

Chill

Immediately transfer the blanched cauliflower to the bowl of ice water. This stops the residual heat in the florets from continuing to cook them. Leave the cauliflower in the ice water for 3 minutes. Drain well in a colander.

Single Layer Freeze

Spread the blanched and chilled cauliflower florets in a single layer on a baking sheet. Freeze for 1 - 2 hours.

Transfer the frozen cauliflower to freezer bags or containers and label with the date. Frozen cauliflower will keep for 1 year. It is still safe to eat after that, but its quality will decline.

Tips

It is not necessary to thaw frozen cauliflower before cooking it.

Subtract the blanching time from the cooking time when you use frozen cauliflower in a recipe.
