A Field Guide to Dill — Feathery, Bright, and the Only Herb That Truly Belongs on Cucumber

Dill is a divisive herb — most people love it or have decided they don’t. It’s also the herb that defines half of Scandinavian, Eastern European, and Middle Eastern cooking, and the only fresh herb that genuinely makes cucumber better.

What dill actually tastes like

Bright, faintly anise, with a soft grassy quality and a subtle citrus note. The feathery fronds are delicate; the stems are surprisingly assertive. The fresh herb and the dried seeds (dill seed) are completely different ingredients — dill seed is warm and almost caraway-like, used in pickling.

The variety to know

Most home cooks only need common dill (Anethum graveolens). “Bouquet” and “Fernleaf” are popular cultivars sold as plants — either is fine. The supermarket bunch is what you’ll buy 95% of the time, and it’s perfectly good. Look for fronds that are bright green and feathery, not yellowing or wilted.

What dill pairs with

Dill loves cucumber, yogurt, sour cream, feta, salmon (cured or fresh), trout, eggs, potatoes, beets, peas, and lemon. It pairs naturally with parsley, chives, mint, and tarragon — the soft-herb family. It does not pair well with rosemary, sage, oregano, or any of the woody Mediterranean herbs; the flavors fight badly. Dill plus garlic plus yogurt plus cucumber is the foundation of tzatziki and half of summer cooking.

When to add it

Almost always raw and at the end. Dill loses its volatile oils within a minute of heat — cook it and you lose 80% of the flavor. The exception is the stems, which can simmer in a pickling brine or a fish poaching liquid where you want a subtler infusion. For fresh dishes, snip the fronds with kitchen scissors over the finished plate.

How to store it

Dill is fragile — second only to cilantro in how fast it can wilt. Trim the stems, stand the bunch in a glass with an inch of water, loosely cover with a bag, and refrigerate. It will hold five to seven days. Dill also freezes well: chop and freeze flat on a tray, then bag it. Frozen dill is fine for tzatziki, soups, and dressings.

Three ways to use dill this week

The site’s recipe library doesn’t yet have a dedicated dill recipe — the herb tends to live in spontaneous, no-recipe applications. Three to try: (1) Quick tzatziki — grated cucumber (salted and squeezed), full-fat Greek yogurt, garlic on a Microplane, a fistful of dill, lemon juice, olive oil, salt; rest 30 minutes before serving. (2) Dilled potato salad — boiled new potatoes, sour cream, dijon, scallions, half a cup of chopped dill, lots of black pepper. (3) Quick-cured salmon — equal parts salt and sugar (¼ cup each), zest of a lemon, a heavy handful of chopped dill; pack onto a 1-lb salmon fillet, cover, and refrigerate 24 hours.

The tools that make dill easier

Kitchen scissors, not a knife — dill’s feathery fronds bruise under a blade. A Microplane zester for the garlic and lemon zest that almost always join dill on the plate. For storage, an upright glass herb keeper extends shelf life dramatically; see How to Store Fresh Herbs So They Actually Last.
