If you haven’t looked already (as it’s very common that people don’t), the official Phoenix Guides are very in depth without going into LiveView (that’s left up to the LiveView guides). It depends on what you are looking for, of course. I’ve never read anything other than those myself (and I could probably use a refresher, honestly).

I liked TDD Phoenix by @germsvel , but it’s still using Phoenix 1.5 unfortunately. Recently I also found dwyl/phoenix-todo-list-tutorial

You will most probably will never find a tutorial that will cover everything.

I would recommend to get started with some basic tutorials. I strongly recommend not using generators, ecto or anything else to minimize the noise.

Phoenix by itself is built on very simple concepts, once you understand how Plugs work, and heex, you will pretty much know 80% of how framework works.
