This Million Dollar Roast Beef Tenderloin is rich, buttery, and unbelievably tender — the kind of centerpiece dish that steals the show at holidays and celebrations. Perfectly seared, oven-roasted, and finished with a garlic-herb butter that melts into every slice.
INGREDIENTS
4–5 lb beef tenderloin, trimmed, cut into two pieces, and tied
1 tsp salt
½ tsp black pepper
2 tbsp olive oil
4 tbsp salted butter, softened
2 tsp minced garlic
1 tsp prepared horseradish or Dijon mustard
1 tsp minced rosemary or thyme
INSTRUCTIONS
PREP THE TENDERLOIN
Tie the tenderloin securely with butcher’s twine to ensure even cooking. Season generously with salt and black pepper. Let it rest at room temperature for about 2 hours for maximum tenderness and even roasting.
PREHEAT THE OVEN
Preheat oven to 425°F (220°C).
SEAR FOR FLAVOR
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 deep golden-brown crust forms.
MAKE THE GARLIC BUTTER
In a small bowl, mix the softened butter, minced garlic, horseradish (or Dijon), and fresh herbs until smooth and fragrant.
ROAST
Spread the garlic butter evenly over the seared tenderloin. Insert a probe thermometer into the thickest part of the meat. Transfer the skillet to the oven (or move the tenderloin to a baking dish if needed). Roast for 20–25 minutes, or until internal temperature reaches your desired doneness
125°F (52°C) for medium-rare
135°F (57°C) for medium
REST
Remove from the oven and transfer to a cutting board. Let rest for 15–20 minutes so the juices redistribute and the meat stays juicy.
SLICE & SERVE
Slice into 1-inch thick pieces and serve warm with the pan juices or your favorite sides.
