Bronze Fennel Uses: Fronds, Stalks and Seeds

Got a patch of bronze fennel? Use it as an herb and a seed plant, not a vegetable: you cook with its fronds, stalks, seeds, flowers and pollen.¹ It’s a purple-leaved garden form of common fennel and tastes of anise like any fennel, but it doesn’t form the white bulb sold as Florence fennel.² Pick the fronds young, while they’re deep purple and taste of licorice, and save the tall stalks for a bed to grill a whole fish on.

Pick the fronds young

The flavor shifts through the season. Forager Chef Alan Bergo finds the young, deep purple fronds taste of licorice, while after flowering they often turn green and taste more vegetal.¹ For anything raw, cut the purple growth.

Fronds in salads and as a garnish

Bergo suggests picking a few fronds and tossing them into a salad.¹ Specialty Produce, a distributor that sells bronze fennel, calls the leaves an attractive garnish for salad, pasta and rice dishes.³ The color is the main reason to grab it over green fronds.

You can also stir chopped fronds into mayonnaise or aioli, a potato salad or slaw dressing, or a citrus vinaigrette, though we didn’t find published recipes for these. Chop them just before serving.

With fish

Fennel and fish come up again and again. Fennel seeds and oil flavor fish, and herb fennel goes into fish dishes.⁴ Two recipes show how the fresh plant gets used:

Recipe	Fish	How the fennel is used	Source
Wild fennel-grilled fish	One 3 to 3½ lb whole fish such as rock cod or sea bass	Six 12- to 18-inch wild fennel branches: a bed on the grill, one stalk in the cavity with lemon, the rest laid over the fish; discarded after grilling	Georgeanne Brennan⁵
Grilled trout with lemon and fennel fronds	Four 1 lb whole trout, or smallmouth bass or branzino	½ cup chopped fronds tossed with lemon, oil and salt, stuffed into the cavities	Saveur⁶

Bronze fennel’s stalks and fronds can stand in for the wild fennel in Brennan’s recipe. Neither forms a bulb, and both are Foeniculum vulgare. Brennan’s own swap for wild fennel is cultivated fennel stalks and leaves plus 2 teaspoons of fennel seeds.⁵

You can also wrap a frond-stuffed fish in foil or parchment and bake it. You’ll sometimes read that bronze fennel suits salmon and other fatty fish best, but we found no source for that.

Stalks

Bronze fennel’s tall stalks aren’t the crisp stalks you get on bulb fennel. Specialty Produce suggests steaming or grilling them and serving them with fish, pork and poultry.³ We didn’t find any source that slices them raw for salad, and older stalks are likely to be stringy. Your best bet is the grilling bed above.

With pasta: a Sicilian model

The classic wild fennel pasta is Sicily’s pasta con le sarde, with sardines. Great Italian Chefs notes that wild fennel grows abundantly in Sicily and says fennel bulbs with their tops, or soaked fennel seeds, make a good substitute where it’s hard to find.⁷ Bronze fennel fronds make a reasonable stand-in for the wild fronds. Specialty Produce also suggests the leaves as a garnish for pasta.³

You may also hear that bronze fennel’s licorice note makes it a natural for tomato and basil red sauces. We found no recipe that shows it.

With root vegetables

Specialty Produce says bronze fennel seeds go well with carrots, beets and jicama.³ Chopped fronds are also nice scattered over roasted carrots, beets or potatoes, or stirred into a cream sauce for potatoes.

In soups, stews and stock

Illinois Extension lists soups and stews among herb fennel’s uses.⁴ If you want the fronds’ aroma, add them near the end. People sometimes say fennel is a staple of French stocks. We found no source for that, but tossing a few stalks into a fish or vegetable stock is a sensible use for trimmings.

In butter and marinades

Compound butter is a great home for fronds.

Ratio (Method): Mix 2 to 3 tablespoons of finely chopped fronds into 4 ounces of softened butter with a pinch of salt, and taste. Use it on fish, vegetables or grilled chicken.

For marinades, chopped fronds with garlic, black pepper, lemon and oil suit chicken and pork. Specialty Produce pairs bronze fennel with pork and poultry,³ though we found no published marinade.

Seeds

The seeds are just fennel seeds. Bergo uses bronze fennel seed in Italian fennel sausage and in rubs and seasonings for fish.¹ Fennel seed also goes into pastries, sweet pickles, breads and biscuits. For more, see fennel seed.

Flowers and pollen

Bergo lists the flowers and pollen among the plant’s edible parts.¹ The pollen is the pricey finishing spice sold as fennel pollen. See fennel pollen uses for how cooks use it.

Tea

Specialty Produce says you can make fennel tea from the seeds.³ You may read that bronze fennel tea has antiseptic effects that help prevent foodborne illness, and that over-steeping destroys its good compounds. We found no source for either, and we’re not making health claims. Germany’s BfR has said fennel tea may contain high amounts of alkenylbenzenes such as estragole, while the health risk couldn’t yet be conclusively assessed.⁸ See bronze fennel for more on estragole.

Keeping it

Specialty Produce says fresh bronze fennel keeps up to 5 days in the fridge.³ Illinois Extension says you can air-dry fennel foliage and store it for later.⁴ Both are general guidance, not measured shelf lives.
