The average "how to cook on a food network" show was, ultimately, one person in the kitchen of a large home cooking for the camera, produced once a week. There are plenty of people delivering that style of cooking show with high production quality today. Obviously it's not the same because some things are less deliverable with smaller or one-person teams (Miss Piggy is not going to visit some Youtube show the way she visited Martha Stewart) but there are people making this content ranging from big shops like NYT Cooking to smaller outfits like Binging with Babish, Glen and Friends Cooking, etc. and there are even outfits like this dedicated to more niche topics like Tasting History or Emmymade.
