What is kohlrabi?

Kohlrabi is a unique vegetable that can be eaten cooked or raw. It’s a mix between a cabbage and a turnip. Trim the leaves, peel the skin, and then treat it similar to a potato. Boil, roast, steam, or add it to a casserole. Kohlrabi gratin or scalloped kohlrabi is especially tasty, and most people will think it’s just a potato casserole.

Can I eat kohlrabi raw?

Yes, kohlrabi slice or sticks are the perfect addition to a crudité platter. Trim the leaves, peel the skin first. When eaten raw, kohlrabi has the flavor similar to radish but sweeter. Try serving with your favorite veggie dip, or add it to the top of a salad for a little crunch. You’ll find it resembles jicama or fennel.

Scalloped Kohlrabi

We have been recently been getting kohlrabi in our weekly CSA box from the Purdue Student Farm. I’ll be honest, I had no idea what to do with this interesting vegetable. I turned to my favorite cookbook when it comes to vegetables called Vegetables on the Side, The Complete Guide to Buying and Cooking.

Each chapter is dedicated to a vegetable, complete with explanations and recipes. It was here that I learned how to cook kohlrabi. I found a recipe for Kohlrabi Gratin with Onions, which is really just another name for Cheesy Kohlrabi Casserole or Scalloped Kohlrabi.

FAQs

Do you peel kohlrabi before cooking? ›

Whether you're cooking kohlrabi or serving it raw, you will need to completely peel and discard the thick, tough outer layer (you may need a sharp knife for this; the skin is quite tough and indigestible). Cut the kohlrabi. To enjoy the crunch of raw kohlrabi, you'll want to cut it into delicate pieces.

What to do with raw kohlrabi? ›

You can eat it raw in slaws and salads, as well as roasted and stir-fried.

Should you cook kohlrabi? ›

All parts of the kohlrabi can be eaten, both raw and cooked. It is delicious steamed, sautéed, roasted, stuffed, creamed, in soup or stew, and eaten raw. Smaller kohlrabi tends to taste sweeter; the vegetable develops a sharper, more radish-like flavor as it matures.

What's the best way to eat kohlrabi? ›

Kohlrabi is incredibly versatile. Cut or slice as desired, steam, and most anything goes. Add steamed kohlrabi to dishes, like stir fries, pasta, soups, and stews. It's also fun to mash them with cauliflower or potatoes.

How do you know when kohlrabi is done? ›

Harvest kohlrabi when the bulb is two to three inches in width. If the bulb gets too large, it will become tough, woody and bitter. Spring-planted kohlrabi harvested in summer is more likely to become fibrous if you allow them to become over-mature. Fall-harvested kohlrabi can grow a bit bigger without losing quality.

What does kohlrabi taste like cooked? ›

A member of the cabbage family, kohlrabi carries a signature sweet-but-peppery flavor profile, with a taste and texture reminiscent of broccoli stems.

Can you eat too much kohlrabi? ›

Kohlrabi is a healthy ingredient, and it's low in calories. Eating too much of any cruciferous vegetable can cause gas that can make you uncomfortable. Moderate your portion sizes to help ensure that you are able to enjoy the benefits of kohlrabi without negative digestive effects.

Should you refrigerate raw kohlrabi? ›

Kohlrabi can be stored in the refrigerator for several weeks. Storage life can be extended if kohlrabi is placed in sealed perforated plastic bags. To prevent cross-contamination, keep kohlrabi away from raw meat and meat juices.

What does kohlrabi taste like raw? ›

What does kohlrabi taste like? Like many members of the brassica family, kohlrabi is subtly sweet and vaguely peppery when you eat it raw. Its texture is akin to a jicama or a broccoli heart, and the faster-maturing spring varieties can be juicy like apples, though rarely as sweet.

Does kohlrabi get soft when cooked? ›

The canonical application for kohlrabi that I'm familiar with is soup, for which you shred the vegetable (or if you're feeling fancy, julienne it). Naturally, the smaller pieces then get pretty soft when cooked.

What is kohlrabi and how do you prepare it? ›

Kohlrabi tastes similar to a broccoli stalk, but a bit more tender and sweet. Don't forget to remove the tough outer peel, then use the bulb either raw or cooked. It can be prepared much like a broccoli stalk, too—if raw, shred it and use it in slaw or thinly slice and use in a salad.

Do you eat the skin of kohlrabi? ›

When serving raw, you may want to gauge the thickness of the skin—if it feels particularly thick and rubbery, you can remove it with a vegetable peeler. But the skin is perfectly edible. Many people actually eat kohlrabi right out of the garden, like an apple, in big crunchy bites.

How do you know when kohlrabi is ready to eat? ›

Kohlrabi is ready to harvest when its bulb is 1 to 3 inches in diameter, or about the size of a tennis ball. Do not pick the vegetable in warm weather, as the root becomes woody. Kohlrabi leaves are also edible.

Why is my kohlrabi bitter? ›

The best quality kohlrabi—sweet, crisp, juicy—results from fast growth without heat or moisture stress. If the plants are overheated or struggling to take up water, they will produce chemicals that have strong, bitter flavors.
