Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F (200°C). Pat the 1.5 lb beef tenderloin dry with paper towels and season generously with salt and pepper on all sides.
  2. Step 2: Heat 1 tablespoon of olive oil in an oven-safe skillet over medium-high heat until shimmering. Sear the beef tenderloin for 3-4 minutes per side until golden brown.
  3. Step 3: Transfer the skillet to the preheated oven and roast for 12-15 minutes for medium-rare, or until internal temperature reaches 130°F (54°C).
  4. Step 4: While beef roasts, heat the remaining 1 tablespoon of olive oil in a separate skillet over medium heat. Add the 1 lb trimmed asparagus and cook for 5-7 minutes until crisp-tender, then set aside.
  5. Step 5: In the asparagus skillet, melt 4 tablespoons of butter over medium heat. Add the 4 minced garlic cloves and cook for 1 minute until fragrant, then stir in the 1 tablespoon lemon juice.
  6. Step 6: Remove beef from oven, let rest for 10 minutes, then slice thinly. Serve beef with asparagus and drizzle with garlic butter sauce.

How do I scale Pan-Seared Beef Tenderloin with Garlic Butter and Asparagus for a different number of people?
