Great question! You do not have to be trained to be a chef!
If you want to be a chef I would suggest reading food blogs, cook books, and food magazines to learn about recipes. You can also get a job in a kitchen and learn about what a day to day looks like for a chef.
I love cooking and am not a chef. The way I learn is by reading as much as I can, and by practicing cooking every day! You can start by making simple meals and soon you will be a well trained chef!
Hope this helps!
