I'm not overly familiar with the website, but the few recipes from it I have come across are usually accompanied with an in-depth recount of the thought process that went into the recipe, including failed experiments and iterations, commentary on the origin of the dish and the author's experience with it, why a certain ingredient or technique was chosen in place of another, etc...

Look for Serious Eats recipes/articles about Ramen, Pizza or Yorkshire Pudding for some good examples.

It definitely looks and feels like OC (I really know nothing about Tasty, so I cannot comment on their alleged plagiarism).
