Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F (200°C). Pat beef dry and season with 1/4 tsp salt and 1/8 tsp pepper. Wrap tightly in plastic wrap and refrigerate for 30 minutes.
  2. Step 2: In a skillet over medium heat, melt 1 tbsp butter. Cook mushrooms and shallots for 8-10 minutes until golden and moisture evaporated, stirring occasionally. Remove from heat, stir in thyme and Dijon mustard, then cool completely.
  3. Step 3: Unroll puff pastry and cut into a 12x8-inch rectangle. Place beef tenderloin in center, then spread mushroom mixture evenly over it. Roll pastry tightly around beef, sealing seams with egg wash.
  4. Step 4: Place seam-side down on a parchment-lined baking sheet. Brush entire surface with egg wash. Bake for 25-28 minutes until pastry is golden brown and internal temperature reaches 125°F (52°C) for medium-rare.
  5. Step 5: Rest for 10 minutes before slicing to allow juices to redistribute.
