A whole beef tenderloin is impressive for a dinner party, especially served with a luxurious sauce. weezieduzzit uses a simple formula for a rich sauce: Reduce a cup of good beef stock by half, then add a cup of brandy and reduce again by half, and finally, add a cup of cream and reduce by half. Season to taste.
This beef tenderloin with roasted shallots, bacon, and port has "the most delicious sauce," foodie_guru says, while abgilliam calls Ina Garten's Gorgonzola sauce "fantastic." And OCEllen says Béarnaise sauce (pictured) is "always show stopping delicious!"
