Preparing Kohlrabi For Freezing
Before you freeze your kohlrabi, there are a few steps you need to follow to make sure it retains the best flavor and texture.
First wash them to remove any dirt or debris, gently rubbing them with a produce brush if necessary. Next, cut the leaves and the stem off each end of the bulb.
Use a vegetable peeler or sharp knife to remove the tough outer skin. Then you can choose to cut it into slices or cubes.
Do You Have To Blanch Kohlrabi Before Freezing?
You don’t have to blanch kohlrabi before freezing. But I recommend doing it because it helps it maintain the crisp texture, and also locks in the fresh flavor.
How To Blanch Kohlrabi To Freeze
To blanch your kohlrabi before freezing, all you need to do is flash-cook it in boiling water for a few minutes.
Fill a cooking pot with water and bring it to a boil on the stove. While you wait, fill a large bowl with ice water.
Once the water comes to a rolling boil, carefully drop in the pieces and let them cook for 2-3 minutes. Do not overcook them.
Remove the pieces quickly using a slotted spoon, place them into an ice bath right away, and let them cool for 1-2 minutes to stop the cooking process.
Methods For Freezing Kohlrabi
Freezing kohlrabi is simple and quick, and there are a few different steps you can follow. The technique you choose depends on the amount of time you have and your personal preference.
Freezing Kohlrabi In Pieces
It’s best to cut your kohlrabi into pieces before freezing it, rather than leaving it whole. This will take up less space, and also results in a better end product.
You can cut the bulbs into either cubes or slices, depending on how you plan to use them later.
Flash Freezing Kohlrabi
Flash freezing is an optional extra step, but it will prevent the pieces from sticking together in one large clump.
Can I Freeze Kohlrabi Leaves & Stems As Well?
Yes you can freeze kohlrabi leaves and stems as well as the bulb. Use small, tender leaves for the best texture and flavor, as the larger ones tend to become tough and woody as they age.
First wash them and pat them dry, or use a salad spinner to remove the excess water.

How To Store Kohlrabi In The Freezer

Instead of plastic bags you could use any type of container you have, as long as it’s airtight to prevent freezer burn.
How Long Does Frozen Kohlrabi Last?
Frozen kohlrabi lasts for about 8 months or longer when properly prepared and stored. To extend the life, try using a food vacuum sealer.
Here are answers for some of the most common questions I get asked about freezing kohlrabi.
Can you freeze kohlrabi without blanching it?
Yes, you can freeze kohlrabi without balancing it. However, skipping this step may degrade the flavor and texture, and it might not last as long in the freezer.
How do I thaw frozen kohlrabi?
The best way to thaw frozen kohlrabi is to rinse it under cool water briefly, or add it directly to your dish while cooking.
Can I freeze kohlrabi raw?
You can freeze kohlrabi raw, but taking a few minutes to blanch it first will preserve the flavor and texture better.
Can you freeze mashed kohlrabi?
I don’t recommend freezing mashed kohlrabi. Mashing it first breaks down the structure of the vegetable, which will most likely cause it to become mushy. It’s better to mash it after you thaw it.
How do you cook frozen kohlrabi?
You can cook frozen kohlrabi the same way you do when it’s raw. Simply place the frozen pieces into a frying pan, or thaw them first. You can add them to any of your favorite recipes, like soups, stir fry, and other dishes.
Does kohlrabi freeze well?
Yes, kohlrabi freezes quite well due to its naturally crisp and hard texture. Blanching it first will help it last longer and preserve the flavor.
Can you freeze kohlrabi whole?
You can freeze kohlrabi whole, however I recommend cutting it up first. When you freeze the bulbs whole they tend to crack, which can negatively impact the texture and taste.
