- One 7 to 10 pound beef tenderloin, trimmed
- Salt and freshly ground black pepper
- Fresh rosemary leaves
- One day ahead of serving: Rinse the tenderloin with cool water and pat dry with paper towels. Generously season with salt, pepper, and rosemary. Wrap the tenderloin in plastic wrap and refrigerate for at least 8 hours.
- Preheat oven to 450 degrees. Remove the wrapping from the tenderloin and place in a shallow roasting pan. Cook for 40 minutes for medium rare. Remove the tenderloin from the oven, cover with foil and let rest 10 minutes. Slice thinly to serve.
