Step‑by‑Step Instructions for Garlic-Rosemary Beef Tenderloin
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). While the oven warms up, line a baking sheet with aluminum foil for easy cleanup, coating it lightly with cooking spray or olive oil. This preparation ensures your Garlic-Rosemary Beef Tenderloin bakes evenly and slides off the sheet effortlessly after roasting.
Step 2: Prepare the Marinade
In a small mixing bowl, combine 1/4 cup of extra virgin olive oil, minced garlic, chopped rosemary, kosher salt, and freshly ground black pepper. Stir until well-blended. This aromatic mixture will infuse your tenderloin with delightful flavors, so set it aside and take in the rich scent while you prepare the beef.
Step 3: Season the Beef
Pat the beef tenderloin dry with paper towels to ensure a good sear and flavor adherence. Generously rub the garlic-rosemary mixture all over the tenderloin, pressing it in gently so it clings to every nook and cranny. This step is crucial for achieving that deeply savory crust on your Garlic-Rosemary Beef Tenderloin.
Step 4: Roast the Tenderloin
Carefully place the seasoned tenderloin on the prepared baking sheet, positioning it ideally in the center. Roast in the preheated oven for approximately 45 minutes to 1 hour, or until the internal temperature registers between 125°F and 130°F for perfect medium-rare. Keep an eye out for a beautifully browned crust, which will signal delicious doneness.
Step 5: Let It Rest
Once your roast reaches the desired temperature, remove it from the oven and let it rest for about 10 minutes. This resting period allows the juices to redistribute throughout the meat, ensuring that your Garlic-Rosemary Beef Tenderloin remains juicy and flavorful when sliced.
Step 6: Slice and Serve
After resting, slice the tenderloin against the grain into thick, succulent pieces. Arrange the slices on a serving platter, showcasing the pink, juicy interior. Consider serving alongside sides like buttery mashed potatoes or vibrant creamed spinach for a truly elegant meal that beckons family and friends to the table.
