How long should you saute a steak for well done?

To achieve a well-done steak, sauté it for about 4-5 minutes per side over medium heat, depending on the thickness of the cut. Use a meat thermometer to ensure an internal temperature of 160°F (71°C) is reached. Keep in mind that cooking times can vary, so it's essential to monitor the steak closely to prevent overcooking. Let it rest for a few minutes before slicing to retain its juices.
