Step-by-Step Instructions

Step 1: Trim, tie, and season the tenderloin

If your tenderloin is not pre-trimmed, remove any large pieces of surface fat and the thick silver skin (the shiny, tough membrane) with a sharp knife, working carefully so you do not gouge the meat. If the roast has a thinner “tail” end, tuck it under so the roast is a fairly even thickness throughout.

Use kitchen twine to tie the tenderloin at 1 1/2–2 inch intervals along its length. This helps it cook evenly and hold a round shape. Pat the meat completely dry with paper towels.

In a small bowl, combine 2 tbsp olive oil, 2 tbsp kosher salt, 2 tbsp coarsely cracked black pepper, and 4 minced garlic cloves to form a loose paste. Rub this mixture all over the tied tenderloin, pressing the cracked pepper so it adheres and fully coats the exterior. Place the roast on a rack set over a rimmed baking sheet or in a large roasting pan.

Step 2: Let the roast stand and preheat the oven

Let the seasoned tenderloin stand at room temperature for about 30 minutes. This takes the chill off the meat so it cooks more evenly and helps the pepper-garlic crust adhere beautifully. Meanwhile, position a rack in the center of your oven and preheat to 275°F (135°C) for gentle, even roasting.

Just before you are ready to sear, pat any very wet spots on the surface with a paper towel (do not remove the seasoning) to avoid steaming. Preheat a large, heavy, oven-safe skillet (cast iron or stainless steel) over medium-high heat.

Step 3: Sear the pepper-crusted tenderloin

Add 1 tbsp olive oil and 2 tbsp butter to the hot skillet. When the butter is melted and the fat is shimmering, carefully lay the tenderloin in the pan. It should sizzle immediately. Sear on the first side, without moving, for 2–3 minutes until a deep golden-brown crust forms. Use tongs to roll and turn the roast, searing all sides and the ends, about 2–3 minutes per side, 8–10 minutes total.

If you like, add 2–3 sprigs of fresh thyme or rosemary to the pan and spoon some of the hot, aromatic butter over the roast as it sears. This builds a flavorful crust and adds a subtle herbal note.

Step 4: Roast to medium-rare perfection

Once the tenderloin is well browned all over, transfer the entire skillet to the preheated 275°F (135°C) oven. Roast until the thickest part of the meat registers 120–125°F (49–52°C) on an instant-read thermometer for medium-rare. This typically takes about 20–30 minutes, depending on the thickness of your roast and how efficient your oven is. Begin checking at the 20-minute mark.

For other levels of doneness, aim for 115–120°F (46–49°C) for rare, 125–130°F (52–54°C) for medium, keeping in mind the temperature will rise 5–10°F (3–5°C) as the meat rests. Avoid going much past 135°F (57°C) with tenderloin, as it can dry out.

Step 5: Rest and slice the beef

Carefully transfer the tenderloin from the skillet to a cutting board, leaving any pan drippings in the skillet for the sauce. Tent the roast loosely with aluminum foil and let it rest for 15–20 minutes. This rest time is crucial; it allows the juices to redistribute and the internal temperature to even out and rise slightly.

After resting, remove and discard the kitchen twine. Slice the roast crosswise into 1/2–1 inch-thick medallions, depending on your preference. For a holiday platter, slightly angle your knife so the slices are just a bit diagonal and show off the rosy interior.

Step 6: Sauté the mushrooms and aromatics

While the beef rests, place the skillet with the pan drippings back on the stove over medium to medium-high heat. If the pan seems very dry, add 2 tbsp olive oil and 2 tbsp butter. Add the minced shallots and cook for 1–2 minutes, stirring, until fragrant and just softened.

Add the sliced mushrooms and 1/2 tsp of the kosher salt. Cook, stirring occasionally, for 8–10 minutes. At first the mushrooms will release a lot of moisture; keep cooking until that liquid evaporates and the mushrooms start to brown and pick up any browned bits (fond) from the pan. Stir in the remaining 2 cloves minced garlic during the last 1–2 minutes of cooking so it softens and becomes aromatic without burning.

Step 7: Deglaze with cognac and finish the cream sauce

Turn off the heat (especially if you are using a gas stove). Carefully pour in the cognac or brandy. If a small flame appears, do not panic; it will die down quickly. Once the alcohol is in the pan, turn the heat back to medium and scrape the bottom of the skillet with a wooden spoon to release all the flavorful browned bits.

Let the cognac simmer and reduce by about half, 2–3 minutes. Add the beef stock, Dijon mustard, thyme, Worcestershire sauce (if using), and remaining 1/2 tsp kosher salt and 1/2 tsp black pepper. Simmer for 3–5 minutes to slightly reduce.

Stir in the heavy cream. Simmer gently (do not boil hard) for 5–8 minutes, stirring often, until the sauce thickens enough to coat the back of a spoon and looks glossy and silky. If you prefer a thicker sauce, stir together the cornstarch and cold water, then drizzle it into the gently simmering sauce, whisking constantly until it reaches your desired consistency.

Taste and adjust seasoning: add more salt or pepper as needed. A teaspoon or two of lemon juice at the end brightens the flavors and keeps the sauce from feeling too heavy.

Step 8: Plate, garnish, and serve

Arrange the sliced beef tenderloin on a warm platter, overlapping the medallions slightly in a shingled pattern. Spoon the hot mushroom-cognac cream sauce generously over and around the beef, making sure plenty of mushrooms land on top of the slices as well as in the sauce below.

Finish with a sprinkle of flaky sea salt, a bit of additional coarsely cracked black pepper for texture, and a shower of chopped fresh parsley or chives for color. Serve immediately, passing any extra sauce at the table. This dish pairs beautifully with mashed potatoes, roasted root vegetables, or a simple green salad.

Pro Tips

• Crack the pepper properly: For the best crust, use whole peppercorns cracked in a mortar and pestle or pulsed briefly in a grinder. You want coarse pieces, not fine powder, so they toast and perfume the crust without turning harsh.
• Do not skip the rest: Resting the roast after cooking is just as important as hitting the right internal temperature. Slice too soon and the precious juices will spill onto the board instead of staying in the meat.
• Use a thermometer: Beef tenderloin is expensive and lean, so an instant-read thermometer is your best friend for perfect doneness. Start checking early; you can always cook it more, but you cannot undo an overcooked roast.
• Control the sauce thickness: Aim for a sauce that slowly runs off a spoon and lightly coats the beef. If it is too thin, reduce a bit longer or add a touch of cornstarch slurry. If it is too thick, whisk in a splash of stock or cream to loosen it.
• Warm your plates: Serve the sliced tenderloin and sauce on warm plates or a warm platter so the meat stays at an ideal temperature while you bring it to the table.

Variations

• Bourbon-mushroom cream sauce: Swap the cognac or brandy for bourbon. The flavor will be a bit sweeter and smokier, which pairs beautifully with the pepper crust. Add a pinch of smoked paprika to echo the bourbon’s character.
• Green peppercorn twist: For a more classic steakhouse feel, stir 1–2 tbsp drained green peppercorns (from a jar in brine) into the sauce near the end of cooking. Their gentle heat and pop of texture are excellent with the cream and mushrooms.
• Steak medallions instead of whole roast: If you cannot find a whole tenderloin, cut individual 1 1/2–2 inch-thick steaks from a smaller piece, crust them with pepper and garlic, sear in a skillet, and finish in the oven. The sauce stays exactly the same.

Storage & Make-Ahead

Make-ahead: You can trim, tie, and season the beef tenderloin up to 24 hours in advance. Keep it uncovered or loosely covered in the refrigerator to let the surface dry slightly (which helps browning). Take it out 30–45 minutes before searing so it can lose some of its chill. The mushroom-cognac cream sauce can also be made up to 1 day ahead; cool completely, refrigerate in an airtight container, and reheat gently over low heat, thinning with a splash of stock or cream if needed.

Storage: Leftover sliced beef and sauce keep well in the refrigerator for 3–4 days. Store them separately in airtight containers if possible. Reheat the beef gently, covered, in a low oven (about 275°F / 135°C) or in a covered skillet with a splash of stock, just until warmed through, to avoid overcooking. Reheat the sauce over low heat on the stove, adding a little stock or cream if it has thickened too much. The sauce can be frozen for up to 2 months; the texture may change slightly, but a quick whisk while reheating usually smooths it out.
