• Salt and pepper
• 2 tablespoons olive oil
• 8 ounces mushrooms, finely chopped
• 1/4 cup shallots, finely chopped
• 2 cloves garlic, minced
• 2 tablespoons butter
• 2 tablespoons flour
• 1 cup beef broth

2. Season the beef tenderloin with salt and pepper.

3. In a large skillet, heat the olive oil over high heat.

4. Add the beef and sear on all sides for about 2-3 minutes per side, or until nicely browned.

5. Remove the beef from the skillet and let it cool slightly.

6. In the same skillet, add the mushrooms, shallots, and garlic. Cook for about 5 minutes, or until the mushrooms have released their liquid and the mixture is dry.

12. Stir in the egg yolk and Dijon mustard.

13. Roll out the puff pastry on a lightly floured surface to form a large rectangle.

14. Spread the mushroom mixture over the puff pastry, leaving a 1-inch border around the edges.

15. Place the beef in the center of the pastry, then roll the pastry around the beef, tucking the edges under to seal.

16. Brush the beaten egg over the pastry, then make a few slits in the top to allow steam to escape.

17. Place the beef Wellington on a baking sheet and bake for about 20-25 minutes, or until the pastry is golden brown and puffed.

18. Let it rest for at least 10 minutes before slicing and serving.
