Perfect Porterhouse Steak

Ingredients:

1 2”-thick Porterhouse steak, trimmed (about 2 lb.)
1 tablespoon vegetable oil
Kosher salt and freshly ground black pepper
3 tablespoons unsalted butter, room temperature

Preparation:

1.Let steak sit at room temperature 30 minutes before cooking, which will help it cook quickly and more evenly.

2.Heat broiler. Heat a large skillet, preferably cast iron, over medium-high heat, then heat oil in pan until smoking. Season steak very generously with salt and pepper and cook until a deep brown crust forms on underside (do not turn), about 4 minutes. Transfer steak to a cutting board, turning it browned side up.

3.Cut meat from bone in 2 pieces (strip steak and filet mignon). Slice both pieces straight down perpendicular to the bone 1” thick. Replace sliced steak around the bone (it should look like a whole sliced steak) and return to skillet, browned side up. Top with butter and broil until butter is melted and steak is medium-rare, 4–6 minutes. Serve steak with buttery pan juices spooned over.
