Whatâs the difference between marjoram and oregano? Depends on who you ask. Many botanists believe they are the same but a chef will tell you the difference is huge. Oregano was long considered âwild marjoramâ but the plants do not look particularly similar. To confuse matters further, marjoram is a member of the mint family and considered the twin of thyme. Marjoram has a more mild, sweet flavor than oregano with perhaps a hint of balsam. It is said to be âtheâ meat herb but compliments all foods except sweets.
