- 1 (4 to 5 pound) fillet of beef, trimmed and tied
- 2 tablespoons unsalted butter, at room temperature
- 1 tablespoon kosher salt
- 1 tablespoon coarsely ground black pepper
Preheat the oven to 500 degrees F.
Place the beef on a sheet pan and pat the outside dry with a paper towel. Spread the butter on with your hands. Sprinkle evenly with the salt and pepper. Roast in the oven for exactly 22 minutes for rare and 25 minutes for medium-rare.
Note: Be sure your oven is very clean or the high temperature will cause it to smoke.
