Remove the beef fillet from the refrigerator and let it sit at room temperature for about 30 minutes. Preheat the oven to 400°F. Season the beef generously with salt and pepper. Heat the olive oil and butter in a large skillet over high heat until hot. Add the beef and sear on all sides until browned, about 2-3 minutes per side. Transfer the beef to a plate and set aside.
Step 2: Prepare the mushroom duxelles
Add the mushrooms, shallots, garlic, and thyme to the same skillet used to cook the beef. Cook over medium heat, stirring occasionally, until the mushrooms release their liquid and it evaporates, about 10-15 minutes. Add the butter and cook until the mixture is dry, about 5 minutes more. Season with salt and pepper to taste.
Step 3: Assemble the Beef Wellington
Roll out the puff pastry on a floured surface to a thickness of about 1/4 inch. Spread the mushroom duxelles evenly over the pastry, leaving a border of about 1 inch around the edges. Place the seared beef fillet on top of the mushroom duxelles. Brush the edges of the pastry with the beaten egg. Fold the pastry over the beef, pressing the edges to seal. Turn the Beef Wellington over, seam side down, and place on a baking sheet lined with parchment paper. Brush the top of the pastry with the beaten egg. Use a sharp knife to score the pastry lightly in a diagonal pattern. Bake for 35-40 minutes, until the pastry is golden brown and the beef is cooked to your liking (use a meat thermometer to check the internal temperature). Let the Beef Wellington rest for 10 minutes before slicing and serving.
