I wouldn't qualify it as a Gen Z thing. As a Xennial, I have a quite a few Gen Z coworkers and most of them actively talk about recipes and meals they're making and they are not just slapping some Mac and Cheese together and calling it. Some of the meals they're talking about cooking are fairly advanced. At least two have dedicated pizza ovens and make their own dough. A number of them are cooking involved multi-course meals I'd never have tried until I was in my late 30's... Hearing their recipes and such I'm fairly impressed on a regular basis.

I think it's more related to experience and available time and CASH. One of them has fallen a bit back into hello fresh, a few times a week, but they just had a kid, so no blame there.
