Quick Answer
Fennel is a crunchy, aromatic vegetable with a distinctive licorice-like flavor. The white bulb is eaten raw in salads or cooked (roasted, braised, grilled). The feathery green fronds are used as an herb. Cooking mellows the anise flavor significantly, making it sweeter and more subtle.
Understanding Fennel
Mediterranean Staple
Fennel is a flowering plant in the carrot family, native to the Mediterranean. It's been used for thousands of years in Italian, Greek, and French cuisines. The entire plant is edible and aromatic.
Mild Licorice Flavor
Fennel has a distinctive anise/licorice taste that's polarizing. But here's the secret: cooking mellows the licorice flavor significantly, turning it sweet and subtle. Many licorice-haters love roasted fennel.
Versatile Vegetable
Raw fennel is crisp and refreshing (perfect for salads). Roasted fennel becomes caramelized and sweet. Braised fennel turns silky and mellow. It's one of the most versatile vegetables in the kitchen.
Fennel Anatomy - What Parts to Use
Fronds (Feathery Tops)
Edible: Yes - use like an herb
Garnish, salads, pesto, finish dishes
💡 Tastes like mild dill meets anise
Stalks
Edible: Yes - but tough
Stocks, broths, flavoring liquids
💡 Too fibrous to eat, great for flavor
Bulb
Edible: Yes - the star!
Raw in salads, roasted, braised, grilled
💡 Remove tough core before cooking
Core
Edible: Technically yes
Usually removed (tough)
💡 Cut out the triangular center
🌱 Zero Waste Vegetable
Fennel is incredibly versatile - nothing needs to go to waste. Bulb for eating, fronds for garnishing, stalks for stocks, and if you let it flower, you can even harvest the seeds. It's one of the most useful vegetables in the Mediterranean cooking tradition.
How to Prep Fennel
Basic Prep Steps
Cut off stalks where they meet the bulb (save fronds!)
Slice off the root end (bottom)
Remove any tough or discolored outer layers
Cut bulb in half from top to bottom
Cut out the tough triangular core from each half
Slice, dice, or wedge as recipe requires
💡 Pro Tips
- →For salads: use a mandoline for paper-thin slices
- →For roasting: cut into wedges through the core (holds together)
- →Rub cut fennel with lemon to prevent browning
- →Don't discard fronds - use like fresh herbs!
⚠️ The Core Matters
The triangular core at the base is tough and fibrous. For raw preparations, always remove it. For roasting in wedges, you can leave a bit attached to hold the layers together - it will soften with cooking.
Cooking Methods
Raw (Sliced Thin)
Crisp, refreshing, bright anise flavor
Best for: Salads, slaws, appetizers
💡 Use a mandoline for paper-thin slices. Toss with lemon to prevent browning.
Roasted
Caramelized, sweet, mellow flavor
Best for: Side dish, pasta topping, grain bowls
💡 Cut into wedges, keep core attached (holds together). High heat = best caramelization.
Braised
Silky, melt-in-mouth, very mild
Best for: Elegant side, with fish or pork
💡 Braise in white wine and chicken broth. Cover until very tender.
Grilled
Charred, smoky, crisp-tender
Best for: Summer sides, salads, Mediterranean dishes
💡 Cut into thick slices, brush with oil. Medium-high heat.
Sautéed
Tender-crisp, lightly caramelized
Best for: Quick side, pasta, risotto
💡 Slice thin, cook in butter until golden at edges.
In Soup
Adds subtle sweetness and depth
Best for: Creamy soups, Italian wedding soup
💡 Sauté first to develop flavor, then simmer.

Frequently Asked Questions

Raw fennel has a crisp texture and mild licorice/anise flavor with a fresh, slightly sweet taste. When cooked, the licorice flavor mellows significantly and becomes sweeter and more subtle. Many people who dislike licorice actually enjoy cooked fennel.
Is fennel the same as anise?
No, they're different plants! Fennel and anise share a similar licorice-like flavor compound (anethole), but fennel is a vegetable with an edible bulb, while anise is an herb used primarily for its seeds. Fennel is milder and less sweet than anise.
What parts of fennel are edible?
All parts of fennel are edible! The bulb is the main attraction (raw or cooked). The feathery fronds are used as an herb (like dill). The stalks are tough but good for stocks. Fennel seeds (from the flowers) are a spice. Nothing goes to waste!
Can you eat fennel raw?
Yes! Raw fennel is delicious. Slice it thin and add to salads - it has a crisp, refreshing crunch like celery with a mild anise flavor. Raw fennel is particularly good with citrus, apple, or in Italian-style salads with olive oil and parmesan.
What can I substitute for fennel?
For texture: celery is the closest substitute. For flavor: a combination of celery + a pinch of anise seeds or fennel seeds. Bok choy stems work for the crunch. There's no perfect substitute for fennel's unique flavor profile.
