Cooking can be really boring to level as a high level player because you have to travel around Azeroth and farm all kinds of meats and eggs for the recipes.
Fortunately, there is a festival called Pilgrim’s Bounty which start at November 21, and ends at November 27. This festival is the best and fastest method to level your Cooking from 1 to 350! The ingredients are so cheap I just wrote estimate numbers, you might need to buy less or more of them.
