I seem to remember the 12th Doctor telling his name (it might have just been his last name) to a character in one episode, about halfway through his run. I'm inclined to think it was "Bazel", although I may be wrong.
Is there actually a 12th Doctor episode where he says his name (and we, the viewers hear it)?
I am looking for the episode (or its lack of existence), not the name itself; there's already a question asking about the name.
The scene you're thinking of is in series 9 episode 8, The Zygon Inversion.
DOCTOR: What's your name?
OSGOOD: Osgood.
DOCTOR: No, no, no. Your first name?
OSGOOD: What's your first name?
DOCTOR: Basil.
OSGOOD: Petronella.
DOCTOR: Let's just, er, stick with what we had.
This is almost certainly a joke, however, like the other instance in the question you linked.
Note: the American pronunciation of the word "basil" has a long A sound, but the British has a short A sound. That's why you're remembering "Bazel".
