Instructions
Remove the steak from the fridge at least 1 hour before cooking to bring to room temperature.
Pat steak completely dry. Rub with olive oil, then coat evenly with the mixed salt, pepper, paprika, and garlic powder.
CAST IRON METHOD: Preheat cast-iron skillet over high heat until smoking hot. Add a drizzle of olive oil and sear steak 2–3 minutes per side until a golden-brown crust forms.
GRILL METHOD: Preheat grill to 500°F (260°C). Sear over direct heat 3 minutes per side, then move to indirect heat.
Add butter, garlic, rosemary, and thyme to the pan. Tilt and baste steak continuously for 1–2 minutes.
Transfer cast-iron skillet to a 375°F (190°C) oven and roast 5–8 minutes, OR continue on indirect grill heat 5–8 minutes, until desired doneness.
Use a meat thermometer: Rare 120°F, Medium-Rare 130°F, Medium 140°F. Remove 5°F before target temperature.
Transfer to a wooden cutting board, tent loosely with foil, and rest 10–15 minutes.
Cut along the bone separating the Filet and Strip sides. Slice each against the grain into thick strips.
Mix butter, garlic, herbs, and lemon zest into compound butter. Place a generous dollop on top of the hot steak and let melt. Finish with a sprinkle of flaky sea salt.
