It's not the verb but the noun..got it wrong because of that
Because "cook" typically takes on its verb form when left alone like this, my first thought was 요리.
I see I'm not alone in needing an article to clarify this is meant to be "A cook" rather than a command.
Anything that ends in ra- is usually a command.
If that's helpful
Chef is more common...
Difference between 요리 & 요리사?
요리 is "cooking" or "dish" while 요리사 is "chef".
