Follow these detailed instructions to create a perfectly cooked and flavorful Herb-Crusted Roast Beef that will impress your family and guests.

1. Prepare the Beef: Take your roast beef out of the refrigerator at least one hour before you plan to cook it. This allows the meat to come to room temperature, which helps it cook more evenly. Pat the roast dry with paper towels. This is a crucial step for achieving a good sear.
2. Preheat the Oven and Prepare the Roasting Pan: Preheat your oven to 450°F (232°C). Place a roasting rack inside a roasting pan. The rack allows for air circulation around the roast, ensuring even cooking and crisping. If you don’t have a roasting rack, you can use sliced onions or carrots as a makeshift rack to elevate the roast.
3. Make the Herb Crust: In a small bowl, combine the chopped fresh rosemary, chopped fresh thyme, minced garlic, olive oil, Dijon mustard, salt, and black pepper. Mix well to create a fragrant herb paste.
4. Apply the Herb Crust: Generously rub the herb paste all over the surface of the beef roast. Make sure to coat all sides and crevices for maximum flavor infusion. Massage the herb mixture into the meat, ensuring it adheres well.
5. Sear the Roast (Optional but Recommended): For an extra flavorful and visually appealing roast, searing is highly recommended. Heat a large oven-safe skillet or Dutch oven over medium-high heat. Add a tablespoon of olive oil (if needed, depending on your pan). Once the pan is hot, carefully sear the roast on all sides until nicely browned, about 2-3 minutes per side. Searing creates a flavorful crust and locks in juices. If you are skipping the searing step, proceed directly to roasting in the oven.
6. Roast the Beef: Place the herb-crusted roast beef on the roasting rack in the prepared roasting pan. Insert a meat thermometer into the thickest part of the roast, making sure it doesn’t touch bone.
7. Initial High Heat Roasting: Roast in the preheated 450°F (232°C) oven for 15 minutes. This initial high heat helps to create a flavorful crust and kickstart the cooking process.
8. Reduce Oven Temperature and Continue Roasting: After 15 minutes, reduce the oven temperature to 325°F (163°C). Continue roasting until the internal temperature reaches your desired level of doneness (see guide below).
   • Rare: 125-130°F (52-54°C)
   • Medium-Rare: 130-135°F (54-57°C) – Recommended for most roasts
   • Medium: 135-140°F (57-60°C)
   • Medium-Well: 140-145°F (60-63°C)
   • Well-Done: 145°F+ (63°C+) – Not recommended for tender roasts as they can become dry

   Roasting time will vary depending on the size and shape of your roast and your desired level of doneness. A 3-4 pound roast will typically take approximately 1-1.5 hours to reach medium-rare. Use a meat thermometer to accurately gauge the internal temperature.

9. Rest the Roast: Once the roast reaches your desired internal temperature, remove it from the oven and transfer it to a cutting board. Tent it loosely with foil and let it rest for at least 15-20 minutes. This resting period is crucial! During resting, the juices redistribute throughout the meat, resulting in a more tender and flavorful roast. Do not skip this step.
10. Make a Pan Sauce (Optional): While the roast is resting, you can make a delicious pan sauce. Place the roasting pan on the stovetop over medium heat. If you have accumulated pan drippings (fat and juices), skim off excess fat, leaving the flavorful browned bits at the bottom of the pan. Pour in the red wine (if using) and scrape up the browned bits from the bottom of the pan with a wooden spoon. This process is called deglazing. Simmer the wine for a few minutes, allowing it to reduce slightly and concentrate the flavors. You can add a tablespoon of butter at the end for richness and a glossy finish. Season with salt and pepper to taste. Strain the sauce through a fine-mesh sieve for a smoother consistency if desired.
11. Carve and Serve: After the roast has rested, carve it against the grain into slices. Serve immediately, drizzled with the optional pan sauce and your favorite side dishes.
