Ingredients:

  • 3–4 lb Sirloin Tip Roast (or Top Sirloin), trimmed
  • 2 Tbsp Coarse Kosher Salt
  • 1 Tbsp Freshly Ground Black Pepper
  • 6 Garlic Cloves, minced fine or pressed
  • 3 Tbsp Fresh Rosemary, finely chopped
  • 2 Tbsp Fresh Thyme Leaves, leaves only
  • 3 Tbsp Extra Virgin Olive Oil

Instructions:

  1. Temper the Roast: Remove the sirloin from refrigeration 1 to 2 hours before cooking to allow it to come near room temperature. Pat the entire roast very dry with paper towels.
  2. Prepare the Crust: In a small bowl, combine the minced garlic, chopped rosemary, thyme, and olive oil to form a thick paste.
  3. Season and Truss: If the roast is irregularly shaped, tie it tightly with kitchen twine every 2 inches to ensure even cooking. Generously rub the roast with the salt and pepper, followed by applying the herb crust paste evenly over all surfaces.
  4. Initial High Heat Sear: Preheat oven to 450°F (230°C). Place the roast fat-side up (if applicable) on the roasting rack in the preheated oven for 15 minutes.
  5. Low Heat Finish: Reduce the oven temperature immediately to 325°F (160°C) without opening the door. Continue roasting until the internal temperature reaches 5–10 degrees below your desired final doneness.
  6. Verify Doneness: Insert the meat thermometer into the thickest part of the roast, avoiding bone or fat pockets. Remove the roast when it reaches the target temperature (e.g., 125°F / 52°C for medium-rare).
  7. Crucial Resting Period: Transfer the roast to a clean cutting board, tent loosely with foil, and allow it to rest undisturbed for 15 to 20 minutes.
  8. Slice and Serve: Remove the twine. Slice the roast against the grain into desired thickness (approx. 1/4 to 1/2 inch) just before serving.
