When using your oven, check cooking progress by looking through the window. Opening the oven door for even a few seconds lowers the temperature inside by as much as 25°F. If your oven doesn’t have a window, try not to open the door to check your food until it’s as close to the expected finish time as possible. Turn off your oven several minutes before your food is fully cooked. As long as the door remains closed, enough heat will be stored inside to finish cooking your meal.
