Seared Sirloin Steak

Ingredients

• 1 sirloin steak, about 1 inch thick
• Kosher salt, to taste
• Freshly ground black pepper, to taste
• 1 tablespoon unsalted butter
• 1 tablespoon olive oil (not extra virgin) or other neutral vegetable oil

1. Pat the steak dry with paper towels. Season both sides with salt and let stand at room temperature, 30 minutes to 1 hour, or refrigerate up to 72 hours. (If refrigerating, bring the steak back to room temperature before cooking by resting for 1 hour.) Pat dry with paper towels and season with more salt and pepper. Press the pepper into the steak to adhere.
2. In a large skillet, melt the butter with the oil over medium-high heat. When the butter foam subsides, add the steak. Sear until a brown crust forms, about 2 minutes per side. Use strong tongs to press the edge of the steak into the pan, rolling and cooking edges until the fat is rendered. Return steak to pan flat-side down, reduce heat to medium, and cook until desired degree of doneness, about 2–2½ minutes for medium rare. For medium rare, the internal temperature should be 125–130°F, internal color should be an opaque, lighter red, and the texture should be just resilient to the touch—droplets of red juice should rise to the surface of the steak. Cooking time will vary based on steak thickness.
3. Remove the steak from pan and transfer to a cutting board or plate, tent with foil, and rest for 5–20 minutes. This is a good time to make a simple pan sauce, if desired. Internal temperature will increase about 5°F during resting. Source
