Prepare the Beef:
Season the beef tenderloin with salt and black pepper. In a skillet over medium-high heat, heat olive oil. Sear the beef on all sides until browned. Remove from the pan and let it cool.
Prepare the Mushroom Duxelles:
In the same skillet, add chopped mushrooms, garlic, and thyme. Cook until the mushrooms release their moisture and become golden brown. Remove excess liquid.
Blend the mushroom mixture to a coarse paste. This is known as mushroom duxelles.
Coat the Beef:
Brush the cooled beef with Dijon mustard. Optionally, spread a layer of pâté over the beef.
Wrap in Mushroom Duxelles:
Spread a layer of mushroom duxelles over the beef.
Roll in Puff Pastry:
Roll out the puff pastry on a floured surface. Place the beef in the center and wrap it with the puff pastry, sealing the edges.
Chill the wrapped beef in the refrigerator for at least 15-20 minutes to allow the pastry to firm up.
Preheat the Oven:
Preheat your oven to 400°F (200°C).
Brush with Egg Wash:
Brush the puff pastry with beaten egg for a golden finish.
Place the Beef Wellington Turnover on a baking sheet and bake in the preheated oven for 25-30 minutes or until the pastry is golden brown and the beef reaches your desired level of doneness.
Rest and Slice:
Allow the Beef Wellington Turnover to rest for a few minutes before slicing. This helps the juices redistribute.
Serve the Beef Wellington Turnover slices on a platter, and enjoy the layers of flavors.
Customize the Filling: Feel free to customize the filling by adding ingredients like caramelized onions, spinach, or different types of mushrooms for additional depth of flavor.
Puff Pastry Tips: Work quickly with puff pastry to prevent it from becoming too soft. If it becomes too warm, you can chill it again before baking.
Make-Ahead: You can prepare the Beef Wellington Turnover up to the point of chilling and then bake it just before serving.
