I usually start with Food Wishes, Serious Eats, or the New York Times. Julia Child for French food, Just One Cookbook for Japanese food. Budget Bytes when the bank account is looking a little thin. Dessert Person when I have a lot of time and want to knock the socks off my friends.
Adam Liaw (Masterchef Australia) is one of my all-time favourites - https://www.youtube.com/@adamliaw
Andy Cooks I’ve been getting into lately - https://www.youtube.com/@andy_cooks
Babish has a good variety as well - https://www.youtube.com/@babishculinaryuniverse
Chef Ranveer for Indian - https://www.youtube.com/@RanveerBrar
The “What’s Eating Dan” series from America’s Test Kitchen is also great for a more scientific look at cooking - https://www.youtube.com/playlist?list=PLnbzopdwFrnZc-UgGYETAQair7VzS7_Z8
