Ingredients

Instructions

  1. Step 1: Pat the beef tenderloin dry with paper towels, then season evenly with 1 tsp kosher salt and 1/2 tsp black pepper. Combine 2 tbsp almond flour, 1 tbsp chopped rosemary, 1 tbsp chopped thyme, and 1 tsp garlic powder in a shallow dish.
  2. Step 2: Press the herb mixture firmly onto all sides of the beef tenderloin, creating an even crust. Heat 2 tbsp butter in a heavy oven-safe skillet over medium-high heat until shimmering, then sear the beef for 3 minutes per side until deeply browned and crust is golden.
  3. Step 3: Transfer the skillet to a preheated 400°F (200°C) oven and roast for 15-18 minutes until the internal temperature reaches 125°F (52°C) for medium-rare, then remove and let rest for 10 minutes. While resting, melt the remaining 2 tbsp butter in the skillet over medium heat, add 3 minced garlic cloves, and cook for 1 minute until fragrant but not browned. Stir in 1 tbsp chopped parsley and pour over the rested beef.
