Remove steaks from refrigerator and any packaging and let sit at room temperature for at least 30 minutes.
Rub each side with the olive oil to coat. Combine the salt, pepper, and white pepper in a small bowl. Rub both sides of each steak with the rub mixture.
Preheat oven to 375 degrees. Preheat a heavy, oven-safe skillet over high heat until it is smoking hot. Sear steaks in the hot pan for 2-3 minutes per side. If the steak has a side of fat, turn the steak onto its side and render the fat by searing it for 2-3 minutes as well.
Slide the skillet with the seared steaks in it into the oven to finish cooking. Remove the steaks from the oven 5 degrees before the desired level of doneness is achieved, or 130 degrees F for medium rare.
While the steaks are cooking, use a fork to combine the butter with garlic in a small bowl.
When the steaks are removed from the oven immediately top with 1 tablespoon of the butter mixture and allow the steaks to rest 10 minutes before cutting into them. The temperature of the steak will continue to rise as it rests by about 5 degrees.
Restaurant Basting Method:
Pat steaks dry. Do not add oil to the meat, but still season generously. Heat 2 tablespoons cooking oil in a large heavy skillet over medium-high heat. Add in steak and sear 2-3 minutes. Flip and sear an additional 30 seconds before adding in 4 tablespoons butter and any aromatics you want to use like rosemary, thyme, or smashed garlic cloves. Tip the pan and use a spoon to start basting the steak with the liquids as it cooks. Once the second side has had a chance to cook for 3 minutes, flip again and continue flipping every 1 minute, basting constantly, until the desired internal temperature is reached.
Preheat your oven to 250 degrees Farhenheit. Place a wire rack onto a rimmed baking sheet. Season steaks as instructed in steps 1 and 2 and place onto the wire rack. Bake in the 250 degree oven until the internal temperature of the steaks reaches 10-15 degrees below your target temperature. Remove from the oven and sear in oil in a heavy skillet over high heat to form a deep golden brown crust.
Preheat an outdoor grill to high heat (about 500 degrees). Sear steaks for 3 minutes per side. Reduce the heat to medium-low and continue cooking with the lid closed until the steaks reach the desired level of doneness (130 degrees F for medium-rare). When the steaks are removed from the grill, immediately top with 1 tablespoon butter each, tent with aluminum foil, and allow the steaks to rest 5 to 10 minutes before cutting into them.
