A typical 1 cup cooked serving of leeks contains 0.8 grams of protein (0.81 g per 100 g), which makes it only a minor source of protein. That covers roughly 2% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Only about 10% of the calories in leeks come from protein, so it is more of an energy food than a protein food. It is worth eating for other reasons; the protein it adds to a day is incidental.
Among the 105 vegetables in the database, leeks ranks 84th by protein per serving, and 752nd out of all 796 foods on the site. Set against alfalfa sprouts, another vegetable entry in the database, a serving carries about 0.5 g less protein (alfalfa sprouts has 1.3 g per 1 cup).
It is an incomplete protein on its own; pairing it with other plant foods across the day covers the full range of essential amino acids. The serving above is measured by volume at 104 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
