Ingredients

Instructions

  1. Step 1: Preheat oven to 425°F (220°C). Place asparagus on a baking sheet, drizzle with 1 tbsp olive oil, and season with 1/4 tsp salt and 1/4 tsp black pepper. Toss to coat and spread in a single layer. Roast for 12-15 minutes until tender-crisp, flipping halfway through.
  2. Step 2: While asparagus roasts, season beef tenderloin on all sides with 1 tsp salt and 1/2 tsp black pepper. Heat 2 tbsp olive oil in a large oven-safe skillet over medium-high heat until shimmering. Sear beef for 2 minutes per side until golden brown.
  3. Step 3: Transfer skillet to oven and roast for 10-12 minutes for medium-rare (internal temperature 125°F), or until desired doneness. Remove from oven and let rest for 10 minutes.
  4. Step 4: While beef rests, melt 3 tbsp butter in the skillet over medium heat. Add 4 minced garlic cloves and cook for 1 minute until fragrant, being careful not to burn.
  5. Step 5: Slice beef tenderloin and serve with roasted asparagus and garlic butter sauce, spooning the butter over the meat.
