My top three resources for cooking:
Alton Brown. I've been a fan of his for over 20 years at this point. He used to make cooking shows for the Food Network, but has been making YouTube videos that are, IMO, his best work yet. He's like the Bill Nye of cooking. Each episode is a deep dive into a topic, with explanations of the science and history behind the steps of the recipe.
J. Kenji López-Alt. He's behind Serious Eats and has a YouTube channel. Serious Eats in particular prefaces their recipes not with filler stories like some sites, but detailed explanations of the decisions they made for the recipe, and often different options you can take. When I want to cook something new, I will usually look for a bunch of recipes from different sources to get a feel for what they have in common and how they differ. If there's an article on Serious Eats, especially by Kenji, I can probably just stop there.
Brian Lagerstrom. These are the most conventional cooking videos on the list, but he's also THE most directly practical cook on this list. By that I mean, there have been more occasions where I've seen him make a recipe, decided to try it out, and actually done it fairly soon after with success. The recipes are very well-explained, and sometimes even shows you why you should do things a certain way by showing you what happens if you don't. Every food presenter will workshop recipes, but it's rare that they show you the failed versions to teach you something!
All of these are great for explaining the process of cooking. It's one thing to just copy a recipe, but understanding the why behind it is so much more useful to teaching you how to cook in general. That helps you build overall skills, and develop the ability to modify recipes, improvise, and maybe even develop your own recipes.
I'll also second Chef John and Babish. When I go looking for a specific recipe, they're names I look out for and know have good information. I also quite like Adam Ragusea, but he is the reason I installed SponsorBlock. (He's gotten much better, but there was a particularly annoying period where he was REALLY chasing ad dollars. Can't really blame him, he has a family and wanted to make a career of the channel, and did.)
Best of luck! Cooking can be fun, and such a good skill to have. :)
