Ingredients

Instructions

  1. Step 1: Pat beef tenderloin dry; rub with Dijon mustard. Mix thyme, rosemary, garlic powder, and flour in a shallow dish; press beef firmly into mixture until evenly coated.
  2. Step 2: Heat 1 tbsp butter in a heavy oven-safe skillet over medium-high heat until shimmering. Sear beef for 3 minutes per side until golden brown, then transfer skillet to preheated 400°F oven.
  3. Step 3: Roast for 15-18 minutes for medium-rare (internal temperature 125°F), then remove from oven and let rest 10 minutes.
  4. Step 4: While beef rests, melt remaining 2 tbsp butter in skillet over medium heat. Add mushrooms and shallot; cook 5 minutes until golden. Pour in red wine and beef broth, scraping browned bits; simmer 5 minutes until sauce reduces by half.
