Instructions:
- Begin by preparing the filling.
- Use a food processor to blend the chopped mushrooms and onions into fine pieces.
- Heat 1 tablespoon of olive oil in a large pan over medium-high heat.
- Once hot, add the chopped sirloin, mushrooms, onions, and thyme.
- Season with salt and pepper to taste.
- Cook for 3-4 minutes until the beef is browned.
- Drain the excess oil if necessary, then stir in the Dijon mustard and set aside.
- Preheat the oven to 400 degrees Fahrenheit and line a baking sheet with parchment paper.
- On a clean surface, roll out both puff pastry sheets side by side.
- Cut each sheet in half from left to right and top to bottom to create 4 equal squares on each sheet.
- Place 1 slice of prosciutto diagonally on each square. If needed, fold the prosciutto in half to fit.
- Spoon the beef mixture into the center of each square, diagonally from the top corner to the bottom corner.
- Close the puff pastry by lightly wetting two opposite corner tips and overlapping, pressing to adhere so they do not open during baking.
- Place the turnovers on the prepared baking sheet.
- In a small dish, scramble the egg and water and brush each puff pastry with egg wash.
- Bake for 20-25 minutes until golden brown.
- While the turnovers bake, prepare the sweet chili wine sauce.
- In a saucepan, whisk together all sauce ingredients except for the cold water and cornstarch.
- Bring to a simmer for about 8 minutes, stirring often.
- Mix cornstarch and cold water in a small bowl, and add to the saucepan over high heat while constantly stirring as it thickens.
- Serve the Beef Wellington Turnovers with Sweet Chili Wine Sauce either as a dipping sauce or by drizzling the sauce over the top.
Enjoy!
Notes:
- If you want to save time, you can prepare the filling a day ahead of time and keep it in the fridge until you’re ready to assemble the turnovers.
- Make sure the puff pastry is fully thawed before rolling it out to prevent cracking.
- The egg wash gives the turnovers a nice golden brown color, but if you’re allergic to eggs, you can use milk or cream instead.
- If you want a more intense flavor, you can add more red pepper flakes to the sauce.
