Fennel is a unique and flavorful vegetable that brings a subtle licorice-like taste and crisp texture to a wide range of dishes. In this guide, you’ll discover the nutrition benefits of fennel, along with simple tips for selecting, storing, and cooking it to perfection. Plus, explore a variety of delicious fennel recipes to help you make the most of this versatile ingredient in your kitchen.

I love picking up a gorgeous bulb of fennel at my farmers market when it’s in season. I also enjoy growing this vegetable—which does well in my California Mediterranean climate—in my garden. The fresh, crunchy anise flavors of fresh fennel in salads just can’t be beat. And the aromatic flavor of fennel seeds is equally delicious in many recipes. For centuries, fennel has influenced the cuisine of the Mediterranean, where it originates. Roasted with greens and beans, caramelized with onions, and flavoring savory foods, fennel pairs particularly well with fall and winter flavors, such as apples and pears.

Nutrition Benefits of Fennel

Related to parsley, dill and cumin, fennel has a white or pale green bulb with green, celery-like stalks, topped with a delicate fringe of leaves. Every part of fennel—seed, bulb, stalk, and leaves—is edible. And it’s super-nutritious; for only 27 calories in 1-cup sliced, you get a reward of 11% DV (Daily Value) fiber, 17% DV vitamin C, 6% DV folate, 10% DV potassium, and 8% DV manganese. And fennel also contains unique phytochemicals with antioxidant activity, such as rutin, quercetin, and kaempferol.

How to Use Fennel

Fresh fennel has a firm, healthy bulb with straight, upward stalks, is lightly fragrant and shows no sign of flowering. It looks similar to dill and is often confused with anise for its lightly licorice scent and flavor. If you are lucky enough to find whole fresh fennel—bulb, stalks, and feathery leaves—don’t be afraid to use the whole fennel, root to stem. Lots of recipes call for sliced fennel bulb. But the stalks, fronds (and even seeds, for that matter) offer so much texture and flavor to dishes, as well. To prepare, cut the stalks where they meet the bulb and slice the bulb into salads and sandwiches. Sautéed or braised, bulbs are traditionally paired with savory dishes, while the stalks add subtle flavor and texture to soups, stews and stock. Feathery fennel leaves lend subtle flavor and enhance beautifully as a garnish.

Top 5 Tips for Cooking with Fennel

1. Perk Up Salads
Fennel is made to take salads to the next level. Its crunch and subtle licorice nuance have a way of pleasing any palate with its unexpected presence. A natural in Mediterranean cuisine, this recipe for Tuscan Asparagus Fennel Farro Salad celebrates all of the flavors of the Tuscan countryside: fennel, onion, olive oil, lemons, pine nuts. Plus, a springy addition of asparagus livens this salad right up!

2. Grill It
Cooking over an open flame may not come to mind when you think of fennel, think again. Slices or wedges of this bulb become mellow and delicately sweet. Drizzle wedges with lemon zest and juice, olive oil and fresh herbs, like chives or thyme, or use slices in salads, or mixed into a savory rice or bean dish.

Try adding sliced fennel along with other veggies in roasted dishes, such as this Roasted Kohlrabi with Pumpkin Seeds recipe.

3. Roast It
The magic of caramelized fennel is matched only by onions. Give it a try with your favorite veggies to roast—zucchini, butternut squash, carrots, potatoes, or a combination of several. Just put veggies on a sheet pan, toss with olive oil, a bit of salt and pepper, and oven roast at 425 degrees for about 20 minutes, tossing once halfway through. Drizzle with red wine vinegar before serving. This would be a great addition to my recipe for Roasted Kohlrabi with Pumpkin Seeds.

Fennel adds a delicious flavor to savory dishes, such as this recipe for Tuscan Kale and White Bean Savory Pie.

4. Add Pizzazz to Savory Dishes
With so many usable parts that resemble other go-to veggies—onion, celery, dill—don’t be afraid to include fennel bulb, leaves, and seeds in savory recipes, such as hearty main dishes, casseroles, pasta, and stews. You can even slice fennel bulb onto an open-faced beet sandwich or veggie burger, like my Edamame Ancient Grain Veggie Burgers, for example. Or serve the stalk in your next crudité plate, or dice and use in dips. The leaves can be added to most anything, from salads to soups, but don’t let their feathery beauty go unappreciated—they have magnificent garnish potential!

Use fennel in a variety of soups, such as this creamy pureed Fennel Carrot Soup with Ginger and Turmeric.

5. Soup it Up
Fennel’s unique flavor makes it as much a seasoning as a main ingredient. For this reason, I love to add any part of it to soups and stews, cooking it into mellow deliciousness that won’t scream out licorice flavor, but will instead induce pause to put one’s finger on that interesting flavor.
