I mainly follow interesting food-related YouTubers:

Wang Gang - Chinese professional chef who does instruction videos on classic Chinese dishes, with a bent towards the Sichuan canon

Chinese Cooking Demystified - Is a bit what it says on the tin. American guy and his Chinese wife living in China, teaching you how to make Chinese food (generally with good insight in how to substitute stuff you can’t find outside of China)

Italia Squisita - Super well known Italian chefs. It started as a page to lol at dumb Americans and Brits ruining Italian food, but now it’s more instructional. They do a good series where they present “basic and gourmet” versions of the same dish.
