Kang first got the idea of writing about vegetation or plants when, as a university student, she came across the work of the noted South Korean writer Yi Sang. In particular, she was struck by the quote "I believe that humans should be plants." Kang's lifelong exploration of the themes of violence and humanity are also sampled in the book, which primarily deals with human beings' natural and daily choices in terms of food. Talking to Sarah Shin for The White Review, she said, "While writing The Vegetarian, I was harboring questions about human violence and the (im)possibility of innocence. On the reverse side of the protagonist Yeong-hye’s extreme attempt to turn her back on violence by casting off her own human body and transforming into a plant lies a deep despair and doubt about humanity." In February 2016, while talking to Bethanne Patrick of Literary Hub, Kang explained, "The idea for the book originally came to me as an image of a woman turning into a plant. I wrote a short story, “The Fruit of My Woman,” in 1997, where a woman literally turns into a plant. After several years (2003–2004) I reworked this image in The Vegetarian, in a darker and fiercer way."
In a February 2016 interview with The Guardian, Han Kang said, "As a teenager I suffered typical questions: why pain, why death? I thought that books held the answers, but curiously I realized they contain only questions. Their writers were weak and vulnerable just like we were." Writing the book was a difficult task, she said, with the main cause being her joint problems which started in her mid-30s. She wrote the entire novella in longhand. Kang received help from a video artist and a psychiatric hospital when researching the book. The second part of the book is primarily inspired by Kang's experiences with the aforementioned artist whose body of work was extensively studied.
The Vegetarian was first published in Korean in 2007 in South Korea as Chaeshikjueuija by Changbi Publishers. ASIA Publishers subsequently bought the rights to the book and published the English translation for distribution in South Korea. It also published the English versions of Kang's short story "Convalescence", and her 2016 novel Human Acts.

The book was translated from Korean into English by Deborah Smith, a British translator, who has been translating Korean into English since 2010. She is the founder of Tilted Axis Press, a non-profit publishing house focusing on contemporary fiction specifically from Asia. Speaking at the Seoul International Book Fair on 15 June 2016, Smith said that a translator "must be unfaithful to some aspects in order to be faithful to others. I try to stay faithful to the spirit, and faithful to the letter as much as I can, without compromising the spirit." Talking about the process, Kang said, "Deborah usually sends me the file of her translation after she finishes, with notes and questions. And I send it back to her with my answers and notes. It is just like having a chat endlessly. I truly enjoy this process. I am lucky to have met Deborah, a wonderful translator who can render subtlety and delicacy." Smith has said that her first attempt at Korean translation involved "looking up practically every other word in the dictionary". Smith has translated some of Kang's other works, including Human Acts (2016) and The White Book (2017).
