Million Dollar Roast Beef Tenderloin: A Luxurious Feast

Tie the tenderloin with butcher’s twine and season generously with salt and pepper.
Allow the tenderloin to sit at room temperature for about 2 hours before cooking to ensure even cooking.
Sear the Tenderloin:

Preheat your oven to 425°F (220°C).
Heat olive oil in a large cast-iron skillet over medium-high heat.
Sear the tenderloin on all sides for 3-5 minutes per side until a golden-brown crust develops.
Prepare the Butter Mixture:

While the tenderloin is searing, mix softened butter, minced garlic, horseradish, and herbs in a small bowl.
Spread the butter mixture evenly over the seared tenderloin.
Roast the Tenderloin:

Insert a probe thermometer into the thickest part of the tenderloin.
Place the skillet in the oven (or transfer the tenderloin to a baking dish if needed).
Roast for about 20-25 minutes, or until the internal temperature reaches your preferred doneness (e.g., 125°F for medium-rare).
Rest and Slice:

Remove the tenderloin from the oven and rest it on a cutting board for 15-20 minutes, allowing the juices to redistribute.
Slice into 1-inch pieces and serve warm.
