How Do You Cook A Whole Beef Tenderloin?
To cook a whole beef tenderloin, preheat the oven to 425°F. Pat the beef dry with paper towels and season with salt and pepper. In a large skillet over medium-high heat, sear the beef on all sides until browned. Transfer the beef to a roasting pan and roast for about 35-40 minutes, or until a meat thermometer inserted into the thickest part of the beef reads 135°F for medium-rare. Let the beef rest for 15 minutes before slicing and serving.
