How Do You Measure A Chopped Onion?
The most common way to measure a chopped onion is by using a measuring cup. Simply scoop the chopped onion into the measuring cup and level it off with a knife or spatula. Alternatively, you can estimate based on the size of the onion you started with and how finely you chopped it. Generally, one medium onion will yield about one cup of chopped onion, while one small onion will yield about half a cup of chopped onion.
