Step 1: Preheat oven to 275°F (135°C). Pat steaks dry with paper towels.
Step 2: Rub steaks with olive oil, then season generously with salt and pepper on all sides.
Step 3: Place steaks on a wire rack set over a baking sheet. Bake for 25-30 minutes until internal temperature reaches 115°F (46°C) for medium-rare.
Step 4: While steaks bake, combine butter, garlic, rosemary, and thyme in a small bowl.
Step 5: Heat a cast-iron skillet over high heat until smoking hot. Sear steaks for 1-2 minutes per side until deeply browned.
Step 6: Top steaks with garlic herb butter and let rest for 5 minutes before serving.
