How to Blanch Fennel

Blanching vegetables is a method of partially cooking vegetables through the plunging of them briefly into boiling water. It can be a way of preserving nutrients so that you can freeze the vegetable or a method of keeping the vegetable crisp for a salad while making it easier to digest.


Fennel is a fall vegetable, and if you want to freeze some for out-of-season use, you can try this method.

Things You'll Need

  • Fennel
  • Sharp knife
  • Large pot
  • Water
  • Colander

Readying the Fennel

  1. Cut out and discard the core of the fennel. Slice the fennel bulb thinly, as if using for a salad.

    Discard the stalks and fronds; these do not freeze well.

  2. Bring a large pot of water to boil.

  3. Put the fennel in the pot, being careful not to splash yourself.

  4. Cook for 3 minutes.

  5. Drain the fennel in the colander and rinse it with cold water to stop the cooking.
