Since heat rises, the top of the oven is often hotter than the bottom. It’s a great place for quick cooking methods like broiling or browning the outside of food. That said, the best rack position for your dish depends on if you want heat on the top of food, the bottom, or evenly distributed. See your oven’s owner’s manual to learn more about the settings it offers and how you can use them to get the best results for your dish.
