What is Fennel?

Fennel is a flowering plant in the carrot family but it is not a root vegetable. It originated in the Mediterranean region but is grown all over the world today. 

The most common type of fennel is Florence fennel also known as Anise fennel. Florence fennel is a vegetable fennel and is shorter than its herb fennel cousin, which grows between 3 and 5 feet tall.

Florence fennel has feathery leaves and a yellow flower. The long stems come together at the bottom to form a crisp bulb that grows above the ground. The leaves, stalks, and bulb have a fresh flavor with a mild hint of licorice. The flowers and seeds have a more potent licorice flavor. Fennel is one of the three main herbs used in the preparation of absinthe, a popular alcoholic drink.

Fennel can also grow naturally in many parts all over the world. Wild Fennel can grow so abundantly that in some places it has been declared an invasive weed. Wild fennel is edible and can be foraged for its stalks, leaves, flowers, and seeds, though, unlike its cultivated cousin, it does not form a bulb.

What Parts of Fennel are Edible?

All parts of the fennel plant are edible. Traditionally the feathery leaves were used when cooking fish but today the crisp bulb is the most popular part of the vegetable. The stalks, flowers, and seeds are also edible and delicious.

How to Eat Fennel

Eating Fennel bulb

The fennel bulb is crisp and has a similar texture to celery. When cooked it caramelizes and develops a sweeter flavor retaining the licorice overtones. It becomes tender and soft.

Slicing the fennel bulb thinly before sautéing ensures they caramelize evenly becoming sweet and soft.

To roast the fennel bulb cut it into large wedges, lay them on an oven pan, drizzle with olive oil, salt and pepper, and roast in the oven for about half an hour until they are caramelized on the edges and soft inside.

Eating Fennel stalks

Fennel stalks are quite tough and can be a bit woody making them difficult to eat. They add wonderful flavor to stocks and broths. Younger stalks are often crunchy and not tough and these can be chopped up into stir-fries, salads, pasta or roasted as you would the bulb.

The stalks, even older woody ones, are great to use as a bed when roasting chicken and other meat as they keep their shape while imparting their flavor into the meat.

Fennel seeds look similar to cumin and have a licorice flavor similar to anise seed. They are brown or green when fresh and slowly turn grey as they dry. Green seeds are the best when cooking but dried seeds are often used too.

The addition of fennel seeds is an important seasoning in many Indian and Middle Eastern dishes and is also an ingredient in Chinese five-spice powder. In Italy, fennel seeds are an important ingredient in making sausage. In India, roasted fennel seeds are used as an after-meal digestive and breath freshener.

Fennel seeds are often used in baking to add a licorice flavor to the goods. So they can be used in both sweet and savory dishes.

A spoonful of fennel seeds can be crushed slightly and added to boiling water to create a delicious and healthy fennel tea.

How to Eat Fennel Flowers

The small yellow fennel flowers are the most potent but also the most expensive part of the fennel plant. They are sometimes known as fennel pollen. A little pollen goes a long way when added to soups, stews, sauces, and meat rubs. They can be used raw in salads or dried and added to dishes. The flowers can also be dried and used to make fennel tea.

How to Buy Fennel

When buying fennel at the grocery store or farmers market choose carefully. Look for a bulb that is heavy and white. Make sure it has no cracks or moist areas and that no parts are starting to turn brown. The leaves should be bright green and the stalks should be crisp.

As fennel dries, it loses its flavor so choose the freshest fennel to ensure maximum flavor.

Fennel will last about four days in the fridge but will have more flavor the sooner you eat it. Once the fennel plant has flowering buds, the bulb is overripe.

Dried fennel seeds can last about 6 months in a sealed container. Be sure to check the expiry date when buying fennel seeds.

Storing Fennel and Preserving Ideas

Fennel Bulbs - Storing Fennel and Preserving Ideas

Fennel bulbs, stalks and leaves only last a few days in the fridge and should be eaten sooner rather than later for maximum flavor. To maximize their shelf life do not wash them until you are ready to use them. Fennel that has come from your garden or farmers market will last a few more days than grocery store-bought fennel.

The leaves and stalks freeze well. Simply rinse in water, dry, and place in a sealed plastic bag. To make using frozen fennel leaves more convenient you can chop the fennel up relatively finely and place it in an ice tray. Make sure each ice cube is packed full of fennel. Pour water into the ice cube hollows to fill up the gaps. Freeze. Remove the fennel ice cubes from the ice tray and place them in a plastic bag in the freezer. Now when your recipe calls for fennel all you need to do is drop one or more fennel ice cubes into the pot.

As the fennel bulb has a high water content it does not freeze as well as the leaves and stalks. If you do want to freeze the fennel bulb, blanch the bulbs first before placing them in a freezer bag in the freezer. You can cut the bulb into wedges before blanching to make it easier to use later.

The bulb can be pickled to lengthen its shelf life. Pickled fennel is great in salads or on its own as a side dish.

Fennel seeds can be dried and kept in an airtight container for up to 6 months.

Fennel flowers can be dried and kept in an airtight container for up to 2 years. An easy way to dry the flowers is to hang them upside down in a paper bag. When they are dry, simply give them a good shake and the flowers should fall to the bottom of the bag.

Health Benefits of Fennel

Fennel is low in calories but high in nutrients. It is packed with dietary fiber, potassium and vitamins A, C and B6. Animal studies have found that fennel may reduce aging-related memory deficit and reduce hot flashes in menopausal women.  Due to fennel’s high potassium content, people with kidney problems should avoid eating large amounts of fennel.
