How to Cook Beef Tenderloin?

Thaw in refrigerator for at least two days before preparing.

Rub Chateaubriand with softened butter then sprinkle with Original Steak Seasoning or coarse salt. Place Chateaubriand fat side up on a rack in a shallow roasting pan. Do not add water or cover.

Roast in 450°F oven until a meat thermometer registers 135°F for medium rare doneness (about 30 to 40 minutes) or 145°F for medium doneness (about 40 to 45 minutes). Beef Tenderloin is best when cooked to medium rare doneness. Well done is not recommended because the meat becomes dry and has less flavor. Allow roast to rest for 10 minutes before slicing.
