'chef-prepared' originates from the combination of 'chef,' a term for a professional cook, and 'prepared,' meaning made ready for use.

'Chef' comes from the French word 'chef de cuisine,' meaning 'head of the kitchen,' while 'prepared' is derived from the Latin 'praeparare,' meaning 'to make ready.'

Initially, 'chef-prepared' simply meant 'prepared by a chef,' but it has evolved to imply a higher quality or gourmet standard.
