Ingredients

  • 3 tbsp Olive Oil: Extra virgin for a smooth base that helps herbs and spices cling to the meat.
  • 2 tsp Salt: Enhances flavor and helps break down proteins for tenderness.
  • 1 tsp Black Pepper: Freshly cracked for subtle heat and aromatic complexity.
  • 4 cloves Garlic, minced: Adds pungent, savory notes that permeate the roast.
  • 2 tbsp Fresh Rosemary, chopped: Woody herb giving a fragrant earthiness to the marinade.
  • 2 tbsp Fresh Thyme, chopped: Offers subtle minty and lemony flavors.
  • 2 tbsp Dijon Mustard: Creates a slightly tangy coating that locks in moisture and flavor.
  • 2 tbsp Worcestershire Sauce: Imparts umami richness and depth to the beef.

Instructions

Preheat the Oven and Prepare Marinade

Set your oven to 425°F (220°C) to ensure it’s fully heated for a perfect roast. While waiting, combine olive oil, salt, black pepper, minced garlic, fresh rosemary, thyme, Dijon mustard, and Worcestershire sauce in a mixing bowl. This marinade blends savory, herbal, and tangy flavors that tenderize and deeply season the beef.

Marinate the Beef Tenderloin

Generously rub the marinade all over the beef tenderloin until thoroughly coated. Let it rest at room temperature for at least 30 minutes. This allows the aromatics to penetrate the meat and encourages more even cooking by taking the chill off.

Prepare for Roasting

Place the marinated tenderloin in a roasting pan and pour the beef broth into the pan. The broth helps keep the environment moist, preventing the meat from drying out and creating delicious pan juices for serving.

Roast to Medium-Rare Perfection

Insert a meat thermometer into the thickest part of the tenderloin. Roast in the preheated oven for approximately 25 to 30 minutes, or until it reaches an internal temperature of 130°F (54°C) for medium-rare. This ensures the beef remains tender, juicy, and full of flavor.

Rest the Meat

Remove the roast from the oven and loosely cover with aluminum foil. Allow it to rest for 10 to 15 minutes to let the juices redistribute, which enhances moisture and tenderness when sliced.

Slice and Serve

Cut the tenderloin into thick medallions and arrange on a serving platter. Drizzle the flavorful pan juices over the slices for added richness. Serve alongside your favorite sides to complete the gourmet experience.

You Must Know

  • Always use a meat thermometer for precise doneness to avoid under- or overcooking.
  • Resting the meat is crucial to prevent juices from running out when sliced.
  • Choosing a tenderloin with good marbling amplifies tenderness and flavor.

Storage Tips

Store leftovers in an airtight container in the refrigerator for up to 3 days. For longer storage, wrap tightly and freeze for up to 2 months. Reheat gently to preserve tenderness and flavor.

Serving Suggestions

This roast pairs beautifully with creamy mashed potatoes, roasted seasonal vegetables, or a fresh green salad. Complement the flavors with a glass of full-bodied red wine like Cabernet Sauvignon or Merlot.

Professional Tips

  • Bring the beef to room temperature before roasting for even cooking.
  • Use fresh herbs whenever possible for brighter, more aromatic flavors.
  • Let the pan juices reduce slightly on the stove to concentrate flavor for a delicious sauce.

FAQs

Can I prepare the marinade the night before?

Yes, marinate the beef overnight in the refrigerator for an even deeper infusion of flavors. Just bring it to room temperature before roasting.

What if I prefer medium doneness?

Roast until the internal temperature reaches 140°F (60°C) for medium. Use a meat thermometer to monitor carefully.

Can I use other cuts of beef?

While tenderloin is ideal for tenderness, you can try a sirloin roast but expect a different texture and possibly longer cooking time.

How do I make the pan juices into a sauce?

Remove the roast and pour pan juices into a small saucepan. Simmer gently to reduce slightly, then finish with a knob of butter for richness.

Is resting the meat really necessary?

Yes, resting allows juices to redistribute, preventing dry slices and improving overall tenderness and flavor.

Can I use dried herbs instead?

Fresh herbs are preferred but dried rosemary and thyme can be used at half the quantity. Adjust seasoning accordingly.
