Baking time refers to the duration required to cook food in an oven. It varies based on the type of dish, temperature, and size of the food. For example, a cake may need 25 to 35 minutes at 350°F, while a roast could take several hours at a lower temperature. Accurate baking time is crucial for achieving the desired texture and flavor. Overbaking can lead to dryness, while underbaking may result in a raw center. Using a timer and checking for doneness with tools like a toothpick or thermometer can help ensure perfect results.
