Season the steak liberally on both sides with the salt, black pepper, and garlic powder. Allow to rest at room temperature while the oven preheats.

Preheat the oven to 400°F.

Line a large baking sheet with parchment paper. Set aside.

Set a large frying pan over high heat and add the olive oil and butter. Once oil mixture is very hot and shimmering, add the steak. Sear without moving until nicely browned on underside, 1-2 minutes. Flip and sear the other side until browned, about 1 minute longer.

Transfer the seared steak to the prepared baking sheet.

Roast the steak on middle rack of oven for 7-10 minutes, depending on desired level of doneness. Allow meat to reach an internal temperature of at least 130°F for a medium steak.

Check to see that steak is done. Remove from oven or add time as needed.

Allow the steak to rest for 5 minutes before slicing and serving. Sprinkle with additional salt if desired.
