Let’s dive into the step-by-step process of freezing kohlrabi. These steps are straightforward, making it easy for any home cook to preserve this nutritious vegetable for future use.

Whether you have a surplus from your garden, or you found a good deal at the farmer’s market, freezing kohlrabi ensures you’ll have this versatile veggie ready for your culinary creations all year round.


First things first, let’s discuss how to freeze this little green gem. Begin by washing the kohlrabi thoroughly. We don’t want any dirt or grit sneaking into our dishes. Once it’s clean, peel off the thick outer skin. You’ll find a tender, delicious interior waiting for you.

Slice or cube

Next, you’ll want to cut your kohlrabi into slices or cubes, whichever you prefer. Just remember, smaller pieces will thaw more quickly later on. Once you’ve got your kohlrabi all chopped up, it’s time to blanch it.


Blaching your kohlrabi involves boiling the pieces for about 2 minutes and then quickly cooling them in ice water. Blanching helps preserve the flavor, color, and texture of the kohlrabi during freezing.


After blanching, spread the pieces out on a baking sheet lined with parchment paper. Freeze them for a few hours until they’re solid.

This prevents the pieces from sticking together in the freezer. Once they’re frozen, transfer them into freezer bags or containers, press out as much air as you can, seal them up, and pop them back in the freezer.

Instead, with your kohlrabi safely stashed in your freezer, you can have peace of mind knowing that you have a stash of this delicious and nutritious veggie ready to jazz up your dishes whenever you please.

Keep in mind, though, while kohlrabi can last up to a year in the freezer, the sooner you use it, the better it will taste.
