The best position for the oven rack depends on what you’re cooking. In a conventional oven, placing the rack on the top third of the oven may help you cook recipes faster and is ideal for broiling, toasting, browning or crisping dishes. Placing the rack on the bottom third of the oven is best for roasting, baking or creating a crust on pies and bread. A convection oven helps cook evenly on all racks so placement is less important for most baking and roasting tasks.
