Step‑by‑Step Instructions for Million Dollar Roast Beef Tenderloin
Step 1: Preparation
Begin by trimming the beef tenderloin to ensure even cooking, cutting it in half if needed. Tuck the thin ends underneath and secure with kitchen twine. Generously season the tenderloin with salt and black pepper, then refrigerate uncovered for 10 hours or overnight to develop flavor. Before you start cooking, let it rest at room temperature for 2 hours, ensuring an even roast.
Step 2: Searing
Preheat your oven to 425°F (220°C). In a large cast-iron skillet, pour a drizzle of avocado oil and heat it over medium-high. Once hot, carefully sear the tenderloin on all sides for approximately 3-5 minutes, achieving a deep golden-brown crust while keeping the inside rare. This process is essential for the mouthwatering flavor of your Million Dollar Roast Beef Tenderloin.
Step 3: Herb Butter Application
While the tenderloin cools slightly, prepare the herb butter by mixing softened salted butter with minced garlic, your choice of horseradish or Dijon mustard, and finely minced rosemary or thyme. Create a smooth, rich mixture. Coat the seared tenderloin thoroughly on all sides using a spatula or your hands, ensuring every part is covered in this flavorful, aromatic butter.
Step 4: Roasting
Insert a probe thermometer into the thickest part of the tenderloin to monitor the temperature. Place the coated tenderloin in the preheated oven and roast for about 20-25 minutes, aiming for an internal temperature of 120-125°F for medium-rare. The exterior should be beautifully browned while the inside remains juicy and tender, embodying the essence of a Million Dollar Roast Beef Tenderloin.
Step 5: Resting and Slicing
Once removed from the oven, let the tenderloin rest on a cutting board for 15-20 minutes, allowing juices to redistribute for maximum flavor. Avoid cutting too soon to ensure the meat stays moist. After resting, slice the tenderloin into 1-inch thick pieces, revealing its perfectly cooked interior, ready to impress your family and guests.
