Ingredients

1 pound mushrooms patted dry
3 tablespoons olive oil
2 1/4 pounds filet mignon
1/2 cup butter
1 small onion finely chopped
2 cloves garlic minced
1 sprig thyme
1 tablespoon flour to dust
13 ounces puff pastry frozen
4 ounces prosciutto
1 large egg whisked

Instructions

Add one tablespoon of olive oil to a large non-stick skillet and place over medium heat. Add the beef fillet and sear on all sides until browned. Remove the beef from the pan and transfer it to a rack to cool.
Add the remaining olive oil and butter to the pan. Add onions and garlic and cook until fragrant. Add the mushrooms and cook for 10-15 minutes, or until soft and dry, with all moisture removed. Add the thyme. Let the mixture cool completely.
Preheat the oven to 200C/400F.
Lightly flour a kitchen surface. Roll out the puff pastry to rectangles (around a scant ½ cm in thickness). Lay the prosciutto over it, overlapping slightly. Add the mushroom mixture over it. Lay the beef fillet over the top. Brush the edges of the pastry with the beaten egg and fold over to cover the beef. Press the edges down, seal both sides, and place on a greased baking tray. Brush the egg wash all over it, then refrigerate for 25 minutes.
Bake for 22-25 minutes, or until golden and puffed up, and the meat is medium rare or reaches an internal temperature of 130-135F. Let it rest for 10 minutes before slicing.

Notes

To store: Let the beef Wellington cool completely, then refrigerate the slices in an airtight container for up to 3 days.

To freeze: I wrap individual slices tightly in foil, place them in a freezer-safe bag or container, and freeze for up to 3 months. Thaw overnight in the fridge before reheating.

To reheat: Preheat the oven to 300°F and reheat for 15-20 minutes, or until the pastry is crisp and the beef is warmed through. I don’t recommend using the microwave, as it softens the pastry.
