Beef Tenderloin Steak Aux Poivre, Pomme Puree Recipe

The key to a moist tenderloin is a two-step cooking process: searing and resting. First, sear the beef in a hot pan for 5–10 minutes to create a browned crust, then finish in a 275°F oven until the internal temperature reaches 125°F. Most importantly, let the meat rest for at least 10 minutes before slicing to allow the juices to redistribute throughout the fibers.

Yes, you can prepare the pomme puree up to 48 hours in advance. Store it in an airtight container in the refrigerator with a piece of plastic wrap pressed directly against the surface to prevent a skin from forming. To reheat, warm it gently on the stovetop over low heat, adding a splash of milk or a knob of butter to restore its signature silky texture.

If you prefer not to use brandy, you can substitute it with cognac or a dry sherry to maintain the depth of flavor. For a non-alcoholic alternative, use a high-quality beef stock mixed with a teaspoon of Worcestershire sauce. While you will skip the flambé step, reducing the liquid “au sec” (until nearly dry) remains crucial for concentrating the peppery notes of the sauce.

A thin sauce usually results from insufficient reduction or skipping the final enrichment step. Ensure you reduce the red wine until it is nearly gone before adding the demi-glace. To achieve a professional, glossy finish, whisk in cold cubes of butter (mounting with butter) just before serving, which adds body and a velvet-like sheen to the sauce.

Absolutely. While traditional potato puree is classic, this recipe works beautifully with a creamy sweet potato mash for a hint of sweetness that contrasts the spicy peppercorns. You can also serve the steak over a parsnip puree or cauliflower mash for a lower-carb option. Regardless of the base, use a stick blender to ensure the texture is perfectly smooth and refined.
