Video of my farms and kitchens at work: The best thing you can do to reduce the time to cook food is to reduce the time it takes for the cooks to haul food back and forth. Kitchens need to be close to your food stockpile, and they also need to be close to the farms. Here is the basic setup for a max population colony. You'll see that for each kitchen there is a path to the stockpile and to the farm, that way if raw food is still lying out on the farm, they can go grab it from there. The distance between the ovens and the raw food is kept as small as possible. You'll also notice that there are no doors on the opposite sides of the kitchen. That prevents other colonists from running through the kitchen and creating a traffic jam. The beds are also there so that the workers can go to sleep and get back to work as quickly as possible. You'll also notice that is why the chapels are so close to the kitchen as well. This is the work crew schedule: I have them working limited shifts because my colony is so happy overall, they don't care. It boosts food production. Same with the farm crew: You'll notice that I have the kitchen staff set to sleep in the afternoons. That's to increase the likelihood that there are open beds closeby. That's also why I have the farmers set to sleep at night. I only give them one shift off, and they are still happy because I have so many other positive happiness modifiers in my colony. I actually don't even need to do that, since they overproduce so much food. They make so much, I don't even need a fully staffed farm crew.
