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.

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.
