Ingredients
1 2-pound bone-in porterhouse steak (about 2 inches thick), room temperature
Coarse salt and freshly ground pepper
1 tablespoon unsalted butter, room temperature
Compound Butter, for serving
Preparation
Preheat oven to 425 degrees.
Heat a large cast-iron or other heavy ovenproof skillet over medium-high heat. Pat steak dry with paper towels. Season steak generously all over with salt and pepper. Add butter to skillet. When melted, place steak in skillet. Cook until well seared, about 4 minutes a side. Transfer skillet to oven. Continue to cook until a thermometer inserted in thickest part of steak reads 120 degrees for medium-rare, 10 to 12 minutes. Transfer steak to rimmed baking sheet fitted with a wire rack. Let rest 10 minutes before slicing. Serve with Compound Butter.
