Season steaks generously with salt, garlic salt, and black pepper mixture.
Preheat your oven to 375 degrees.
Add olive oil to a large cast-iron skillet over high heat. Once the oil is hot, add the meat and sear all sides and edges until browned (about 15-30 seconds per side) to seal in the juices.
Place skillet with steaks in the oven for 6 to 8 minutes or until internal temperature of meat reaches 120 degrees. Remove from oven and let stand for 3 to 4 minutes, allowing the meat to reach an internal temperature of 135 degrees – a perfect medium rare.
