To make one cup of chopped green onions, I removed the small portion on the root ends and chopped the green onion from the white stem up to the tips of the leaves. It took 6 whole pieces of medium-sized green onions to make a cup of chopped green onions, weighing 3.46 oz or 98 grams.

Most often, recipes that include green onions require either chopped or sliced, depending on the type of dish. So if your recipe calls for a cup of chopped green onions, choose a medium-sized bunch with 6 or 7 stems. But if it suggests sliced green onions, go for half a bunch only.

One chopped small green onion can make about 2 tablespoons, while one medium-sized chopped green onion can make 3 ½ tablespoons. However, using the green leaves alone will yield 1 ½ and 2 ½ tablespoons of small and medium green onions, respectively.

Usually, green onions for garnishing are chopped or thinly sliced. If the ingredients require 1 tablespoon of chopped green onion, you will have to cut ½ of your small green onion or a little more than ⅓ of medium green onion.
