All about LEEKS: season, buying, storing, using, flavour combinations, alternatives, and 50+ RECIPES

(Approx. reading time 5 mins 10 secs)

Leeks are an underrated vegetable, usually only used in soups where the flavour gets sadly lost. They are an allium, which makes them a member of the onion family along with garlic, shallots and chives and full of flavour!

Leeks are affordable, easy to find, incredibly versatile and, when cooked properly, delicious. When raw the flavour can be very strong, but when cooked it becomes sweet and delicate. Leeks are also a great way to eat fresh vegetables in winter when not much else is available unless it’s imported (especially if you live in colder climates).

Check all the posts where I talk about onions.

Leeks have been part of our menus for centuries. There’s archaeological evidence of leeks being used in ancient Egypt and Mesopotamia. And it is now one of the symbols of Wales where it’s commonly used is dishes like leek and potato soup and cock-a-leekie.

If you’d like to try growing your own, check the RHS website for great information. Leeks are a good way to keep your garden productive during Autumn and Winter as they are the easiest member of the onion family to grow.

Season

Leeks can be found in markets from September to May, but they are at their best between October and March.

Leeks are most definitely a Winter and Autumn vegetable, but thanks to greenhouses, nowadays leeks can be found year-round.

Buying

Leeks should be firm and undamaged. The green parts should be bright and the white unblemished.

Avoid buying trimmed and pre-chopped leeks, they are very expensive and dry out a lot faster. If you’re going for convenience, it’s better to get frozen leeks (usually sliced) or canned (either sliced or whole baby leeks).

Baby leeks tend to be more expensive than fully grown, but the flavour is also more delicate. If you enjoy eating baby leeks, you might want to try growing your own.

Storing

Cut the roots and any dried out tops on the leeks and keep in the fridge for up to two weeks inside a plastic container or a bag. Don’t wash the leeks until you’re going to use them or you’ll risk them going bad faster.

Leeks can also be frozen whole or chopped (and they are now also sold in the frozen section of supermarkets), and they will last up to one year if properly protected.

If you’re growing your own leeks, you can keep them in the garden until you need them. They will just grow bigger and somewhat thicker, but that can be solved by either cutting them smaller or cooking them longer.

Using

Leeks can have a lot of dirt between the leaves. Cut them lengthwise in half or quarters and wash them under running water. If you’re going to chop the leeks, chop them first and then wash with running water as well. Throw away the hard root if you didn’t before (or better, keep them to make stock).

The green tops can be used, their flavour is less like onions and more like greens. They can be stringy, so better left for stocks, or blended soups. Outer leaves can be used unless they are damaged or dried.

Once chopped 1 kilo (2 pounds) of leeks will be between 4 to 5 cups (depending on how much is discarded and how big or small the leeks are cut).

  • Raw: baby leeks can be sliced or chopped and eaten raw. Fully grown leeks can be eaten raw if sliced very thinly and used sparingly as the flavour can be overwhelming. Best for salads or as garnish.
  • Fried: best for chopped leeks or baby leeks. Fry until soft or golden. Can be used as an onion replacement for the base of a sauce, soup, or stew.
  • Deep fried: best for baby leeks. When battered and deep fried they go great on a tempura platter.
  • Stir-fried: chopped or baby leeks, takes about 5 minutes.
  • Steamed: for chopped or baby leeks.
  • Boiled: for chopped, whole, or baby leeks. It should take between 5 to 10 minutes. Be careful because over-boiled leeks become mushy and slimy. A great addition to soups and stews, but a bit bland as a side.
  • Roast: best for whole or baby leeks. Leeks can be roasted uncovered (and turning every 10 minutes or so) or wrapped in foil.
  • Grilled: for whole or baby leeks. They can be grilled on a hob or open fire, uncovered or wrapped in foil. A great BBQ vegetable.
  • Braised: best for chopped or baby leeks. Fry for a few seconds, add stock and cover. It should take between 10 and 20 minutes depending on the thickness.
  • Pickled: yes, leeks can be pickled, either as real or quick pickles. Baby leeks are best, but it will also work for the white section of fully grown ones if sliced.

Flavour combinations

Much like onions, leeks go with pretty much everything savoury and they are in fact a great alternative to onions.

However, there are some flavour combinations that make the leeks be at their best:

  • Vegetables: potatoes, green leaves, winter squashes, carrots, green beans, garlic, cauliflower, peas, artichokes, seaweed, mushrooms, celery, bell peppers.
  • Fruits: citrus, apples, prunes, raisins.
  • Herbs, spices, and condiments: vinegar, paprika, parsley, aniseed, coriander, bay, thyme, mustard, soy sauce, tarragon, sage, ginger, chilli.
  • Others: cheese, nutritional yeast, chicken, smoky flavours, pasta, bread, rice, tofu, barley, lentils, beans.

Alternatives

If you’re not a fan of leeks or if you’re trying to cook a recipe that calls for them but you don’t have any leeks at home, don’t worry. There are several ways to replace leeks in recipes, either with ingredients that taste similar or fulfill the same function.

  • If used for flavour: yellow or brown onions, shallots, ramps (basically wild leeks, they can be very hard to find in shops but easy to forage), or negi (a Japanese vegetable).
  • If used as a garnish: green onions (scallions)
  • If used as a vegetable side: asparagus, chard, pak choi.
