1 3-lb. beef tenderloin, trimmed of fat
2 T. extra-virgin olive oil
1 tsp. kosher salt
1/2 tsp. freshly ground pepper
2/3 C. chopped mixed fresh herbs, such as chives, parsley, chervil, tarragon, thyme
2 T. Dijon mustard
Preheat oven to 400 degrees F.Â Tie kitchen string around tenderloin in three places so it doesn’t flatten while roasting. Rub the tenderloin with oil; pat on salt and pepper. Place in a large roasting pan.Â Roast until a thermometer inserted into the thickest part of the tenderloin registers 140 degrees F for medium-rare, about 45 minutes, turning two or three times during roasting to ensure even cooking. Transfer to a cutting board; let rest for 10 minutes. Remove the string.Â Place herbs on a large plate. Coat the tenderloin evenly with mustard; then roll in the herbs, pressing gently to adhere. Slice and serve.
1. Very cold meat won’t roast evenly. Place it on the counter while preheating the oven.
2. Durable cotton kitchen string is sold at kitchenware stores, most gourmet markets and large supermarkets. Do not use sewing thread or yarn, which may contain inedible dyes or unsavory chemicals.
3. A heavy-duty, high-sided roasting pan is essential for conducting heat evenly. Never substitute a cookie sheet. A broiler pan will work in a pinch, but the roast will inevitably be somewhat chewier.
4. Give it a rest. A roast’s internal temperature will rise about 10 degrees while resting. The natural juices will also reincorporate into the meat’s fibers and the skin or crust will dry out slightly for a more toothsome yet more succulent dinner.
