Ingredients

Instructions

  1. Step 1: Pat beef tenderloin dry with paper towels. Rub with 1 tbsp avocado oil, then mix chopped rosemary, chopped thyme, minced garlic, 1 tsp sea salt, and 1/2 tsp black pepper. Press mixture evenly over all sides of beef.
  2. Step 2: Heat 1 tbsp avocado oil in a large skillet over medium-high heat until shimmering. Sear beef for 3 minutes per side until golden brown.
  3. Step 3: Transfer beef to a wire rack on a baking sheet. Roast in a preheated 400°F oven for 12-15 minutes for medium-rare, or until internal temperature reaches 130°F.
  4. Step 4: While beef rests, heat olive oil in the skillet over medium heat. Add sliced mushrooms and cook for 8-10 minutes until golden and tender, stirring occasionally.
