How to Freeze Cauliflower

Step 1: Cut and wash

Chop up your fresh cauliflower into nice bite-size bits, sectioning off florets from the stem with a sharp knife. Want to avoid a mess on your counter-top? Here’s expert advice for how to cut cauliflower from Ina Garten, the Barefoot Contessa herself.

Next, thoroughly rinse the florets in a good-size colander in the sink, to get rid of any residual dirt. Pat dry with a clean dish or paper towel and get ready to blanch.

Step 2: Blanch

Next, fill a large saucepan with enough water to cover the cauliflower and bring to a boil. Add the florets and let boil for 1-2 minutes. Drain, then immediately place in a bowl full of ice water for 1-2 minutes. This technique is known as blanching. By boiling the fresh vegetables, you kill any bacteria and the partial cook time locks in the cauliflower’s vitamins, helping it stay (and taste!) fresh once frozen.

Drain the cauliflower and pat dry with a clean towel.

Step 3: Individually freeze the florets

To ensure that your cauliflower doesn’t stick together in one frozen chunk, you’ll want to first freeze the cauliflower individually. To do this, place cauliflower florets in a single layer on a waxed paper- or foil-lined baking sheet—don’t overcrowd them—and freeze for 1-2 hours.

Step 4: Freeze (again!)

You’re almost done! Transfer the frozen cauli florets to a heavy-duty freezer bag. Label with the use-by date and stick it back in the freezer for storage.

Cauliflower can be frozen safely for up to eight months. Learn more about freezing food of all kinds, next.
