FIRST STEP: PREPARE THE BEEF TENDERLOIN

1. Trim the Beef Tenderloin: Start by trimming any excess fat or silverskin from the beef tenderloin. This will help the roast cook evenly and prevent any chewy or fatty bits from ruining the experience.
2. Season the Beef: Pat the beef tenderloin dry with paper towels to remove any moisture. This is key to achieving a good sear. Rub the olive oil all over the meat, then sprinkle the salt, pepper, minced garlic, rosemary, and thyme evenly over the surface. Press the seasoning gently into the meat to ensure it sticks. Let the roast sit at room temperature for 30-60 minutes before cooking to ensure even cooking.

SECOND STEP: SEAR THE BEEF TENDERLOIN

1. Preheat the Oven: Preheat your oven to 425°F (220°C). This high temperature will help form a beautiful golden crust on the beef.
2. Sear the Roast: Heat a large oven-safe skillet (preferably cast iron) over medium-high heat. Once the pan is hot, add the seasoned beef tenderloin and sear it for 2-3 minutes on each side until a golden-brown crust forms. Make sure to sear the edges as well. This step locks in the juices and flavor of the beef, creating a deliciously crispy exterior.

THIRD STEP: ROAST THE BEEF

1. Roast the Tenderloin: Once the beef is seared, transfer the skillet to the preheated oven and roast the tenderloin for 25-35 minutes, depending on your desired level of doneness. For medium-rare, aim for an internal temperature of 125°F (52°C); for medium, roast until it reaches 135°F (57°C). Use a meat thermometer to check the temperature for accuracy.
2. Rest the Roast: Once the roast reaches your preferred level of doneness, remove it from the oven and let it rest for 10-15 minutes. Resting is crucial, as it allows the juices to redistribute, ensuring the beef stays moist and tender.

FOURTH STEP: MAKE THE GARLIC HERB BUTTER

1. Prepare the Butter: While the roast is resting, prepare the garlic herb butter. In a small bowl, combine the softened butter with the fresh parsley, rosemary, thyme, lemon juice, and salt. Mix well until all the ingredients are evenly incorporated.
2. Spread the Butter: After the roast has rested, spread a generous amount of the garlic herb butter over the top of the beef. Allow the butter to melt into the warm roast, creating a rich, flavorful coating.

FINAL STEP: SLICE AND SERVE

1. Slice the Roast: Using a sharp knife, slice the beef tenderloin against the grain into thick slices. This ensures that each piece is tender and easy to eat.
2. Serve and Enjoy: Arrange the slices on a platter, drizzle any remaining garlic herb butter over the top, and garnish with fresh herbs if desired. Serve alongside your favorite sides, such as roasted vegetables, mashed potatoes, or a fresh salad.
