Pat the sirloin steaks dry with paper towels. Season with salt, pepper, and smoked paprika. Heat 2 tablespoons of olive oil in a large cast-iron skillet over medium-high heat. Once the oil is shimmering, carefully place the steaks in the hot skillet. Sear for 3-4 minutes per side for medium-rare, or longer for desired doneness.

In the last minute of cooking, add 2 tablespoons of butter and minced garlic to the skillet. Tilt the skillet and spoon the garlic butter over the steaks, basting continuously. Remove the steaks from the skillet and set aside to rest for 5-10 minutes before slicing.
