Remove the steaks from the refrigerator shortly before cooking while you prepare the remaining ingredients. Pat both sides thoroughly dry with paper towels, as excess moisture can prevent proper browning. Season generously with salt, black pepper, and optional smoked paprika. Drying the surface and seasoning evenly help this sirloin steak recipe develop a delicious crust.

Place a heavy skillet over medium-high to high heat and allow it to become thoroughly hot. Add the olive oil and swirl it around the pan. The oil should shimmer but should not produce excessive smoke. A properly heated skillet helps create the browned surface that gives this sirloin steak recipe its steakhouse-style flavor.

Carefully place the steaks in the hot skillet, leaving enough space between them. Let them sear without moving for approximately 3–4 minutes, depending on thickness and heat. When a deep golden-brown crust forms, flip the steaks using tongs. Avoid pressing down on the meat because doing so does not improve browning and can cause juices to escape.

Reduce the heat slightly and add the butter, crushed garlic, rosemary, and thyme. Once the butter melts and begins to foam, tilt the pan carefully and spoon the fragrant butter over the steaks repeatedly. Continue cooking the second side for approximately 3–4 minutes, adjusting the time to achieve your preferred doneness. This garlic-butter technique adds richness and helps make the sirloin steak recipe especially flavorful.

Insert an instant-read thermometer horizontally into the thickest part of each steak, avoiding contact with the pan. For food safety, the USDA recommends cooking whole beef steaks to 145°F (63°C), followed by at least a three-minute rest. If you prefer a different level of doneness, remember that lower temperatures carry additional food-safety risks. Cooking time varies with steak thickness, starting temperature, and pan heat, so use temperature rather than time alone.

Transfer the steaks to a clean plate or cutting board and let them rest for at least three minutes; five to ten minutes can be helpful for thicker steaks. Spoon a little garlic butter over the top and finish with chopped parsley or a squeeze of lemon juice. Slice against the grain when serving, which shortens the muscle fibers and makes each bite easier to chew. Serve your freshly cooked sirloin steak recipe while warm.
