- 1 tsp Freshly Ground Black Pepper (Added after brine, just before roasting)
- 2 tbsp Vegetable Oil (For high‑heat searing)

- 2 tbsp Tomato Paste (Adds depth and umami)
- 2 cup Red Wine (Medium‑bodied (Pinot Noir or Merlot) for reduction)
- 2 cup Beef Broth (Low‑sodium preferred)
- 1 Shallot (Thinly sliced)
- 2 tbsp Soy Sauce (Low‑sodium for extra umami)
- 1.5 tbsp Granulated Sugar (Balances savory flavors)

Instructions
Trim the Tenderloin
Using a flexible boning knife, remove the chain (the long muscle on the side), excess visceral fat, large pockets of fat, and all silver skin from the whole untrimmed tenderloin.
Time: PT15M
Divide and Tie
Cut the trimmed tenderloin into two pieces of roughly equal size (about 1 inch below the head for the larger piece). Tie each piece with kitchen twine at 1‑inch intervals, using a double loop knot at the tail end to keep the shape.
Time: PT10M
Dry‑Brine with Salt
Pat the roasts dry, then coat all sides with 1 tbsp kosher salt per roast (total 2 tbsp). Wrap each tightly in plastic wrap to prevent leakage.
Time: PT5M
Refrigerate for 12 Hours
Place the wrapped roasts on a rack in the refrigerator for 12 hours (up to 24 h, but not longer).
Time: PT12H
Temperature: 4°C
Season with Pepper
Remove the plastic wrap, pat the roasts dry again, and season all sides with freshly ground black pepper.
Time: PT5M
Low‑and‑Slow Roast
Preheat the oven to 250°F. Place the roasts on a rack in a roasting pan and roast until the internal temperature reaches 125°F (medium‑rare). The larger piece takes about 2 hours, the smaller about 1 hour 30 minutes.
Time: PT2H
Temperature: 250°F
Prepare Sauce Ingredients
While the meat roasts, cut the reserved chain into 1‑inch pieces.
Time: PT5M
Brown the Chain
Melt 1 tbsp unsalted butter in a saucepan over medium‑high heat. Add the chain pieces and sauté until a deep brown fond forms, about 12 minutes.
Time: PT12M
Temperature: Medium‑high
Add Tomato Paste
Stir in 2 tbsp tomato paste and cook for 2 minutes to develop flavor.
Time: PT2M
Temperature: Medium‑high
Build the Red‑Wine Reduction
Add 2 cups red wine, 2 cups beef broth, the sliced shallot, 2 tbsp soy sauce, 1.5 tbsp sugar, and 6 sprigs thyme (stems and leaves). Bring to a boil, then reduce heat and simmer until the liquid is reduced to about 4 cups (12‑15 minutes).
Time: PT15M
Temperature: Medium
Strain the Sauce
Pour the mixture through a fine mesh strainer into a clean saucepan, discarding solids.
Time: PT2M
Thicken with Cornstarch Slurry
Mix 2.5 tsp cornstarch with 1 tbsp cold water. Whisk the slurry into the boiling sauce and cook for about 30 seconds until slightly thickened.
Time: PT1M
Temperature: Medium‑high
Finish with Butter
Whisk in 4 tbsp cold unsalted butter, one tablespoon at a time, until the sauce is glossy and velvety.
Time: PT3M
Temperature: Low
Keep Sauce Warm
Cover the sauce and keep it on low heat, stirring occasionally, until the roasts are ready.
Time: PT5M
Temperature: Low
Rest the Roasts
Remove the roasts from the oven, tent loosely with foil, and let rest for 20 minutes. This allows juices to redistribute.
Time: PT20M
Sear for Crust
Heat 2 tbsp vegetable oil in a 12‑inch skillet over medium‑high until almost smoking. Pat the roasts dry again and sear all sides, turning constantly, for 5‑7 minutes until a deep mahogany crust forms.
Time: PT7M
Temperature: Medium‑high
Remove Twine and Slice
Trim off the kitchen twine, then slice the roasts into ½‑inch thick slices on a cutting board.
Time: PT5M
Plate and Garnish
Arrange the sliced beef on a serving platter, drizzle with the red‑wine sauce, and sprinkle 1 tbsp minced parsley over the top.
Time: PT2M

Critical Steps — Do Not Skip
- Trim all silver skin and excess fat to prevent chewiness
- Dry‑brine with kosher salt for at least 12 hours
- Roast at 250°F until internal temperature reaches 125°F for perfect medium‑rare
- Sear quickly after resting to develop a deep crust without overcooking the interior
Chef Tips from the Video
- Tie the roasts tightly so they keep a uniform shape for even cooking
- After the low‑and‑slow roast, a quick high‑heat sear adds flavor without overcooking the interior
- Use a combination of butter and oil for searing to get both flavor and a high smoke point
Troubleshooting
Roast is dry after cooking
Ensure the internal temperature does not exceed 130°F; use a meat thermometer and remove from oven at 125°F, then let rest.
Sauce is too thin
Whisk the cornstarch slurry thoroughly and add it while the sauce is boiling; cook an extra minute to achieve desired thickness.
Crust is not brown enough
Pat the meat completely dry before searing and make sure the skillet oil is near smoking before adding the roast.
Storage
Refrigerator: Store sliced beef and sauce in airtight containers for up to 3 days.
Freezer: Freeze whole roasted tenderloin (wrapped tightly) for up to 2 months; thaw in refrigerator before reheating.
Room temperature: Do not leave at room temperature longer than 2 hours.
Make-Ahead Tips
- Dry‑brine the tenderloin up to 24 hours in advance
- The red‑wine sauce can be made a day ahead; reheat gently over low heat and whisk in a little butter before serving
- Roasted beef can be sliced and stored; gently re‑warm in a low oven (250°F) before serving
