Food blogging is an enormous market. The best foodies don't get money from Adsense though, it's through sponsorship/affiliate deals, books if they hit it big.
It's quite a stereotyped field though, and I would imagine it's a saturated market. Everyone wants to be like Deliciously Ella [1]. Don't even try unless you have a studio setup for the photography. Lots of food authors are pivoting towards more (usually female oriented) "lifestyle" blogs which happen to have recipes.
A lot of food blogs target healthy eating, or niche diets like keto/paleo. There are also tons of specialist food blogs covering bread, cakes, etc.
