Pan-searing is done in a skillet using a small amount of oil to achieve a browned crust. This method is effective for porterhouse steak, as it allows for control over the heat. Start by heating the skillet on medium-high; then add oil and the steak. Sear each side for about 3 to 4 minutes before transferring the skillet to an oven set at 400°F (204°C) until the desired doneness is reached. The American Meat Science Association notes that pan-searing can create flavorful crusts while retaining juices. Using a meat thermometer can help ensure that the steak reaches the proper internal temperature for even doneness.
Should Porterhouse Steak Be Sear Before Cooking in the Oven?
Yes, porterhouse steak can benefit from searing before cooking in the oven. Searing enhances the flavor and texture of the steak.
Searing creates a caramelized crust on the outside of the steak. This process locks in juices and improves the overall taste. The Maillard reaction occurs during searing, which produces complex flavors and appealing aromas. This initial high-heat step also helps to establish a beautiful, golden-brown exterior, while the oven ensures the steak cooks evenly throughout. Thus, combining both methods results in a more flavorful and enjoyable dish.
