What is Fennel? (And How to Cook It)

Welcome to fennel 101! This underrated veggie deserves a place on everyone's table. Read on to learn how to cut it, how to cook it, and more!

Fennel

Everyone goes crazy for kale, but if I had my way, fennel would be all the rage too. It’s one of the most underrated vegetables, and if you’re not already cooking with it, you absolutely should be. It has a fresh, aromatic anise flavor, and it can be eaten raw, sautéed, roasted, or even added to soups and sauces. If you’ve never worked with it before, this funky-looking veggie might be intimidating from the outside, but don’t let it scare you. Once you know how to approach it, it’s easy to work with.

What is fennel?

Fennel is a member of the carrot family, though it’s not a root vegetable. The base of its long stalks weave together to form a thick, crisp bulb that grows above ground. Above the bulb, at the tip of the stalks, it has light, feathery leaves that resemble dill. When it goes to seed, fennel also produces small yellow flowers among the leaves. Every part of it is edible, from the bulb to the flowers, and it can be eaten raw or cooked.

Though the stalks and leaves are edible, fennel recipes most often call for the bulb. When raw, it has a crisp texture similar to celery and a fresh licorice flavor. It caramelizes as it cooks, taking on a sweeter flavor and tender, melt-in-your mouth texture.

And did I mention that it has all sorts of health benefits too? It’s low in calories, but high in nutrients like dietary fiber, potassium, and vitamin C, to name a few.

Shaved fennel

How to Cook Fennel

One of my favorite things about fennel is that its character changes depending on how you cut it. And with this vegetable, how you cut it and how you cook it go hand in hand.

If I’m craving raw fennel, I almost always thinly shave the bulb on my mandoline, removing any tough core pieces. Then, I marinate it in lemon juice, olive oil, and salt. This crisp, thinly sliced fennel is delicious on its own or in a larger salad. Dress it up with herbs, nuts, and shaved Parmesan cheese, toss it with greens and simple vinaigrette, or use it in one of these salad recipes:

Shaving fennel is also a great move if you want to sauté it. The thin slices will melt and brown in the pan, taking on a delicious caramelized flavor. Try this technique in my Sun-Dried Tomato Pasta Recipe!

How to cut fennel

If I plan to roast fennel, I slice it 1/2-inch wedges. First, I clip off the stalks so that I’m left with the white bulb. I cut it in half vertically and then cut each half into several wedges.

How to cook fennel

To roast the wedges, spread them cut-side-down on a baking sheet with a little space between each one. Toss them with olive oil, salt, and pepper, and roast at 400 degrees for 25-35 minutes, until the wedges are tender and caramelized around the edges.

Serve the wedges as a side dish with a squeeze of lemon or add them to a salad. You could also remove the tough core pieces and toss the roasted fennel with pasta or add it to a hearty vegetarian lasagna.

Fennel fronds

Recipes most often call for the bulb, but don’t toss those tops! Finely mince the fronds to use as an aromatic garnish for salads, soups, pasta, and more, or save the fennel stalks and leaves to use in homemade vegetable broth.

    Thank you for this article! I just wanted to mention that flannel seeds are also very aromatic and you can roast in alongside you other spices such as coriander seeds and grind it for different dishes. We add some flannel seeds to our bread dough when making bread and it makes it so much better.
