How many calories are in a leek?

One trimmed leek weighs about 89g and is 54 calories, and a cup of chopped leek works out to the same weight and the same 54. Per 100g leeks are 61 calories, which is more than onion at 40 and roughly double cabbage at 31.

Why are leeks higher in calories than onions?

Mostly carbohydrate. Per 100g a leek is 61 calories against an onion's 40, and the gap is 14.2g of carbs per 100g against onion's 9.3g of carbs per 100g. It is still a vegetable you would have to eat a lot of to notice: three whole leeks come to about 160 calories.

Are leeks keto-friendly?

In small amounts. Leeks are 12.4g of net carbs per 100g, so a whole leek is 11g, which is most of a strict 20g day. Half a leek softened into a sauce for two people costs about 3g each, and that is the sensible way to use them on keto.

Do leeks have much iron?

More than most vegetables: 2.1mg of iron per 100g, so one leek carries 1.9mg. That is about a quarter of an adult man's daily 8mg and a tenth of the 18mg a menstruating woman needs. It is non-heme iron, so vitamin C alongside it helps absorption, and leeks bring 12mg of vitamin C per 100g of their own.

What part of a leek do you eat?

The white and pale green shaft, which is what the 61 calories per 100g here describes: USDA measures the bulb and lower leaf portion. The dark green tops are edible but fibrous, and most cooks save them for stock rather than throwing them out.

Does cooking change the calories in leeks?

Boiling does, because the leek takes on water and loses some solids to the pot, and USDA files boiled leeks as a separate item at close to half the calories of the raw one by weight. Softening them in butter or oil goes the other way: a tablespoon of butter across two leeks roughly doubles the total.

Are leeks good for you?

They carry 59mg of calcium per 100g, 83mcg of vitamin A per 100g and 180mg of potassium per 100g, which is a broader spread than an onion of the same weight. Like garlic and onion they belong to the allium family and contain the same sulfur compounds those are studied for.

How do you clean leeks properly?

Grit hides between the layers, so rinsing the outside does nothing. Slice the leek lengthwise or into rounds first, then drop the pieces into a bowl of cold water and swish: the sand sinks and the leek floats. Lift them out rather than pouring, or you tip the grit back over them.

How long do leeks last in the fridge?

Whole and unwashed, about two weeks in the crisper, longer than most alliums that have been cut. Wrap them loosely, since a sealed bag turns the outer layers slimy. Once sliced they go soft in three or four days, and washed leeks keep worse than dirty ones.
