Knowing how to cook a steak to a requested doneness makes the difference between an edible meal and one sent back to the kitchen. Sirloin steak is a cut of lean beef trimmed from the rump area to make for a less tender consistency. Pan-frying sirloin keeps the steak cooking in its own juices so flavor is not lost. The steak is cooked to medium-well when the exterior appears charred and the interior is almost cooked through.
Place the sirloin on a plate and season it with salt and pepper. Use other dry seasonings of your choice such as onion, garlic salt, rosemary or oregano. Alternatively, place the steak in a bag filled with marinade and put it in the refrigerator to marinate prior to cooking.
Heat a skillet on medium-high. Coat the skillet with olive oil or butter. Place the seasoned steak in the skillet and pan-fry the steak for 12 to 14 minutes. Flip it halfway through with tongs or a spatula for even doneness.
Check the sirloin with a meat thermometer throughout the pan-frying process. The sirloin is cooked to medium-well when the thermometer reads 165 degrees Fahrenheit.
