Ingredients

• 1 center-cut beef tenderloin, trimmed and tied (2.5–3 lb / 1.1–1.4 kg)
• 2–2½ tsp kosher salt
• 1½ tsp freshly ground black pepper
• 2 Tbsp Dijon mustard
• 3 garlic cloves, finely minced
• 2 Tbsp fresh rosemary, finely chopped
• 1 Tbsp fresh thyme, chopped
• 2 Tbsp fresh flat-leaf parsley, finely chopped
• 1 tsp lemon zest (optional)
• 3 Tbsp olive oil, divided (2 Tbsp for herb paste, 1 Tbsp for searing)
• 1 Tbsp unsalted butter (optional, for basting)

Cookware

• Butcher’s twine
• Paper towels
• Small mixing bowl and spoon or brush
• Heavy oven-safe skillet (12-inch) or roasting pan
• Wire rack and rimmed baking sheet (optional but recommended)
• Tongs
• Instant-read thermometer
• Aluminum foil
• Sharp carving knife

Steps

1. Prep the tenderloin
   • Pat dry thoroughly. Tie with butcher’s twine every 1.5 inches for even thickness. Season all over with salt and pepper. For best flavor, refrigerate uncovered 4–24 hours, otherwise proceed.
2. Bring to temperature and preheat
   • If refrigerated, remove 45–60 minutes before cooking. Preheat oven to 425°F (220°C) with rack in the center.
3. Make the herb paste
   • In a small bowl, combine garlic, rosemary, thyme, parsley, lemon zest (if using), and 2 Tbsp olive oil. Stir into a spreadable paste.
4. Sear
   • Heat 1 Tbsp olive oil in a heavy skillet over medium-high until shimmering. Sear tenderloin on all sides (including the ends) until well browned, about 6–8 minutes total.
5. Coat with Dijon and herbs
   • Transfer briefly to a board. Brush all over with Dijon, then press the herb paste onto the surface to adhere. Set on a wire rack over a sheet pan or return to the skillet.
6. Roast
   • Roast until the center reaches your target pull temperature:
     • Rare: 115°F (46°C)
     • Medium-rare: 120–125°F (49–52°C)
     • Medium: 130°F (54°C)
     • Timing is typically 20–30 minutes, depending on thickness and starting temperature. Rotate the pan halfway for even cooking.
7. Rest
   • Transfer to a cutting board, tent loosely with foil, and rest 15 minutes. Carryover heat will rise about 5°F, and juices will redistribute.
8. Finish and slice
   • Optional: melt 1 Tbsp butter in the hot pan and spoon over the roast for gloss. Snip the twine. Slice into ½-inch medallions. Sprinkle with a pinch of flaky salt if desired and serve.

Green Peppercorn Cognac Sauce Recipe

Luxurious yet quick, this classic steakhouse sauce marries briny green peppercorns with cognac, shallots, and cream. Silky, peppery, and savory, it elevates roasted beef tenderloin in minutes without fussy techniques.

Ingredients

• 2 Tbsp unsalted butter, divided
• 1 small shallot, finely minced (about 2 Tbsp)
• 1/4 cup cognac (or brandy)
• 1/2 cup low-sodium beef stock
• 3/4 cup heavy cream
• 2 Tbsp green peppercorns in brine, drained and lightly crushed
• 1 tsp Dijon mustard
• 1/2 tsp Worcestershire sauce (optional)
• 1 tsp fresh lemon juice (or 1/2 tsp sherry/white wine vinegar), to taste
• Kosher salt, to taste
• Optional: 1–2 Tbsp pan drippings from the roast
• Alcohol-free substitute for cognac: 1/4 cup low-sodium beef stock + 1 tsp sherry or apple cider vinegar

Step

1. Set up the pan
   • Use the same skillet you roasted/seared the beef in (fond adds flavor). Pour off excess fat, leaving about 1 teaspoon. Place over medium heat and add 1 tablespoon butter. If you saved 1–2 tablespoons pan drippings, add them now.
2. Sweat the shallot
   • Add minced shallot with a pinch of salt. Cook, stirring, until translucent and fragrant, 1–2 minutes (do not brown).
3. Deglaze with cognac (two safe options)
   • Non-flambé: Off heat, add the cognac. Return to medium heat and simmer, scraping up browned bits, until nearly evaporated and syrupy, 60–90 seconds.
   • Flambé (optional): Off heat, add the cognac. Return to low-medium heat and, using a long lighter, carefully ignite the vapors. Let flames subside naturally, then reduce to a syrup. Keep hair and sleeves away, never pour alcohol from the bottle over a flame.
   • Alcohol-free: Use 1/4 cup beef stock plus 1 teaspoon sherry or apple cider vinegar, reduce to a syrup as above.
4. Add stock and reduce
   • Stir in the beef stock. Simmer briskly until reduced by about half, 2–3 minutes.
5. Build the sauce
   • Lower heat to medium-low. Stir in heavy cream, crushed green peppercorns, Dijon, and Worcestershire (if using). Simmer gently (small lazy bubbles), stirring often, until slightly thickened and glossy, 3–5 minutes. Avoid a hard boil.
6. Finish and balance
   • Off heat, whisk in the remaining 1 tablespoon butter for sheen. Add lemon juice (or a splash of vinegar) to brighten. Taste and season with salt as needed.
7. Optional straining
   • For a smoother texture, strain through a fine-mesh sieve, then stir some peppercorns back in for appearance and bite. Or serve rustic and unstrained.
8. Adjust consistency
   • Too thick? Whisk in a splash of warm stock or cream. Too thin? Simmer a minute longer to reduce to a nappé consistency (it should thinly coat the back of a spoon).
9. Hold and reheat
   • Keep warm on the lowest heat or in a warm spot, stirring occasionally. If reheating later, warm gently over low heat and whisk in a splash of cream or stock to prevent splitting.
10. Serve

• Spoon over sliced herb-crusted beef tenderloin just before serving. The sauce will thicken slightly as it cools,thin as needed right before plating.

Doneness Guide for Beef Tenderloin

Beef tenderloin cooks quickly and overcooks easily. Use temperatures, rest time, and a thermometer to hit your preferred doneness. This guide translates numbers into cues so each slice stays tender.

Target Temperatures

These are practical pull and final temperatures for beef tenderloin. Pull early, then rest to finish gently. Use an instant-read thermometer for confidence and consistency, especially with varying roast sizes.

• Rare (cool red center): Pull 115–120°F (46–49°C), final after rest 120–125°F (49–52°C)
• Medium-rare (warm red center): Pull 125–130°F (52–54°C), final 130–135°F (54–57°C)
• Medium (warm pink center): Pull 135°F (57°C), final 140°F (60°C)
• Medium-well (slight pink, not recommended): Pull 145°F (63°C), final 150°F (66°C)

Carryover Cooking Explained

Carryover cooking is the gentle rise in internal temperature after you remove the roast from the oven. Heat stored in the hotter exterior migrates inward, equalizing the temperature and continuing to cook the center. For a 2.5–3 lb beef tenderloin, expect a 3–5°F (2–3°C) rise during a 10–15 minute rest, thicker or heavier roasts can climb 5–8°F. This is why you pull early: to land exactly on your target doneness without overshooting. Resting also relaxes muscle fibers, allowing juices to redistribute so slices stay moist instead of spilling onto the cutting board.

Visual Cues vs. Thermometer Accuracy

Visual cues help, but lighting, crust color, and thickness can mislead. A thermometer removes guesswork. Combine both for best results when carving tenderloin for guests and when cooking different thicknesses.

• Finger press: soft and very springy = rare, gently springy with some resistance = medium-rare, firmer with minimal give = medium.
• Color of juices is unreliable, brightness varies with lighting, not just doneness.
• Peek cuts release juices, avoid slicing to “check”, use a thermometer instead.
• Insert the probe sideways into the thickest center, avoid touching the pan.
• Wait 5–10 seconds for a stable reading, check two spots and use the lowest number.
• Time-per-pound is only a guideline, temperature is the definitive measure.

Chef Tips for a Delicious Beef Tenderloin Entree

These chef-tested pointers remove guesswork and streamline your roast. From salting strategy to pan management and temperature control, they help you nail a crisp herb crust and juicy, rosy slices.

Salt Early for Deeper Seasoning and Better Browning

Season the trimmed, tied tenderloin with 1 to 1¼ teaspoons kosher salt per pound and refrigerate it uncovered on a rack for 4–24 hours. The dry brine penetrates for fuller flavor and dries the exterior for superior browning. Short on time? Salt immediately before searing and pat very dry, skip the in-between window when salt draws moisture to the surface.

Shape and Tie for Even Cooking

Beef tenderloin tapers, tie it every 1½ inches to create a uniform cylinder and tuck the thin tail under. Even thickness equals even doneness, preventing overcooked ends and underdone centers. After searing, position the seam down and place the roast on a rack for airflow. Rotate the pan halfway through roasting to minimize hot-spot variance.

Dry, Then Sear Hot, Without Smoking

Moisture is the enemy of crust. Pat the roast thoroughly dry, then heat a heavy skillet until oil shimmers and just begins to smoke. Sear without fiddling to build deep color, rolling to brown all sides and the ends. Use a high-heat oil (avocado, grapeseed) and good ventilation, if the pan smokes aggressively, reduce heat slightly to avoid bitter char.

Make an Herb Paste That Clings

Chop herbs very fine and combine with minced garlic, lemon zest, and enough olive oil to form a spreadable paste. Use Dijon as a binder after searing, brush a thin coat, then press the herb paste to adhere. Apply off heat to prevent premature scorching. If paste looks oily, add more chopped herbs. If it’s too dry, whisk in a few drops of oil.

Trust Temperature Over Time

Start checking early with a fast, accurate thermometer, insert sideways into the thickest center and avoid the pan. For medium-rare, pull at 120–125°F, knowing carryover rises about 5°F as it rests. Thickness, starting temperature, and oven precision swing timing significant, so let temperature call the shots. Calibrate your thermometer occasionally and verify in two spots, using the lowest reading.

Rest, Hold Warm, and Slice Cleanly

Rest at least 15 minutes, tented loosely with foil, this preserves juices and finishes cooking gently. To hold 30–45 minutes, place on a rack in a 150°F oven with the door slightly ajar to limit additional carryover. Snip the twine, then slice with a long, sharp carving knife in ½-inch medallions. Sprinkle flaky salt just before serving for bright finish.

FAQ: Herb-Crusted Beef Tenderloin Recipe

• Can I use a low-temperature “reverse sear” for more even doneness?
  • Yes. Roast the untopped tenderloin on a rack at 250°F (120°C) until 10°F (6°C) below your target (for medium-rare, pull around 115°F/46°C). Rest 10 minutes, then hard-sear in very hot oil 45–60 seconds per side. Brush with Dijon, press on the herb paste, and set the crust in a 400–425°F (205–220°C) oven for 3–5 minutes to avoid scorching the herbs.
• How do I cook the whole tenderloin on a grill?
  • Use a two-zone fire. Sear over high, direct heat 1–2 minutes per side for color, then move to indirect heat (lid closed) at 350–375°F (175–190°C) until the center hits 120–125°F (49–52°C) for medium-rare. Apply Dijon and the herb paste after searing, then finish on the indirect side 3–5 minutes to set the crust. Keep a drip pan under the roast and rotate once for even cooking.
• Can I make the tenderloin sous vide?
  • Absolutely. Bag the salted, tied tenderloin with a knob of butter and a sprig of thyme, cook 2–3 hours at 129°F (54°C) for medium-rare (125°F/52°C rare, 133°F/56°C medium). Shock in an ice bath 10 minutes, pat bone-dry, then sear in a ripping-hot pan 45–60 seconds per side. Brush with Dijon, apply the herb paste, and briefly bake at 425°F (220°C) for 3–5 minutes to set the crust before slicing.
• How much tenderloin should I buy, and what cut is best?
  • Plan 6–8 ounces (170–225 g) trimmed tenderloin per adult for a plated dinner, 4–6 ounces (115–170 g) for a buffet with many sides. Ask for a center-cut (chateaubriand portion) trimmed of silver skin and tied. Expect a 10–15% weight loss from trimming and cooking. Choice grade offers excellent value, Prime yields extra marbling and tenderness. Ask the butcher to tuck and tie the tail if not using a center-cut.
• What’s the best way to handle leftovers, and can I freeze them?
  • Refrigerate slices tightly wrapped for 3–4 days. Reheat gently: Place sealed slices in a 250°F (120°C) oven on a rack until just warm, or place them in a 120–130°F (49–54°C) water bath for 10–15 minutes. Avoid microwaving to prevent overcooking. The sauce can be stored refrigerated for 2–3 days. To rewarm, heat gently and whisk in a splash of cream or stock. Freezing cooked tenderloin isn’t ideal for texture, but raw, trimmed tenderloin freezes well for up to 6 months, thaw in the refrigerator before cooking.
