Which of the OG6 Avengers can cook?
Based on the evidence from the films, I divided our six into three groups.
Group 1: Don't cook and don't try
Throughout his journey in the MCU, Clint has shown no signs of cooking skills, only eating skills.
We've seen him eating Laura's food, obviously, Grills' cooking, restaurant food and takeout. But he's never cooked on screen, and hasn't shown any willingness to do so.
No evidence of culinary skills, despite the assumption that it would be wise for the Red Room to teach Black Widows to be good housewives. The Red Room did not, as we can observe in this illustration:
Nat was never seen cooking, and even when it made sense to cook, she chose ready-to-eat foods or simply made a sandwich.
But she knows how to make cocktails, so that's a plus.
Group 2: Do try, but they better not
Self-admitted that he sucks at cooking, but at least he tries.
It makes sense that he knows the basics, but he learned them during a time of not-so-great taste. It doesn't look like he was trying to take it to the next level, but it does look like others have had some experience with his cooking, and now it's an entertaining topic.
He can cook eggs. With varying success. What else he can do (with more consistent success) is start fires and experiments.
For which he ends up being kicked out of the kitchen of his own house.
By the way, the kitchen is officially Pepper's, which already says something.
Group 3: Cook and do it well
Bruce can cook. But despite the fanon that he is a super chef who can cook dishes from all the cuisines of the world, there is no evidence of this in the films.
Instead, we are shown him preparing very simple dishes, and he is not always confident in his skills.
Perhaps between his solo film and She-Hulk he's gotten better in that regard.
What he definitely knows how to do is prepare different cocktails.
If this post can be considered a top list, then Thor will most likely be our winner.
He cooks food from different cuisines (apparently from different planets), serves it skillfully, learns quickly and shows enthusiasm.
And we can see this already in his first film. When he first arrived on Earth, he was already using the toaster oven and making French toasts, which he had probably never tried before.
He then cooked for Jane and learned to make excellent pancakes, judging by her reaction.
And even though his food doesn't always look appetizing to Midgardians, he knows what he's doing.
He can also make you a Bloody Mary for breakfast.
Thus, once again we come to the destruction of stereotypes. This time the stereotype that since Thor had servants for most of his long life, he cannot have the desire to cook and cannot learn and do it well. In fact, he turns out to be the closest thing on the team to a professional chef.
