It depends on where you live and what type of environment you grow up in. I can tell you that in a lot of southern and/or rural areas of the US, old school household gender roles are still frequently adhered to. That's the case for much of my family for instance, most of the women still do the bulk of the cooking. My family is also sort of split as to how they treat women as well. There is a significant chunk of my family who still hold the sexist "women belong in the kitchen and are inferior to men" mindset (and it's not going away anytime soon as even the kids are being taught this), that's on my maternal grandmother's side. My maternal grandfather's side is immensely more egalitarian and doesn't generally demand adherence to gender roles, but even there, the women STILL usually gravitate towards cooking.
Restaurants are different however. Even going way back in time, it was common for men to be the cooks. In fact, some restaurants even frowned upon women being involved in cooking (especially the upscale ones requiring a lot of expensive higher education, Ratatouille referenced this in its plot with Colette). If you look at lists of the best and most famous chefs in the world, men vastly outnumber women.
