How long should I cook a steak on each side to achieve the desired level of doneness?

The cooking time for a steak depends on its thickness and desired doneness. A general guideline is to cook a 1-inch thick steak for about 3-4 minutes on each side for medium-rare, 4-5 minutes for medium, and 5-6 minutes for well-done. It's important to use a meat thermometer to ensure the steak reaches the desired internal temperature.
