Equipment

  • 1 baking sheet
  • 1 parchment paper
  • 1 skillet
  • 1 mixing bowl
  • 1 rolling pin
  • 1 pastry brush
  • 1 meat thermometer optional

Ingredients
  

  • 1 pound beef tenderloin, trimmed and cut into 1-inch pieces
  • 8 ounces cremini mushrooms, finely chopped
  • 4 tablespoons unsalted butter, divided
  • 2 cloves garlic, minced
  • 1 teaspoon fresh thyme, chopped
  • 1 tablespoon Dijon mustard
  • to taste salt and pepper
  • 1 sheet puff pastry, thawed
  • 1 egg beaten (for egg wash)

Instructions
 

  • Preheat the oven to 400°F (200°C) and line a baking sheet with parchment paper.
  • In a skillet over medium-high heat, melt 2 tablespoons of butter and add the chopped mushrooms. Cook until browned and liquid has evaporated, about 5-7 minutes.
  • Add minced garlic and thyme to the skillet and cook for an additional minute. Season with salt and pepper to taste, then remove from heat and let cool.
  • In a mixing bowl, combine the beef pieces with the cooled mushroom mixture, stirring in Dijon mustard until well combined.
  • Roll out the puff pastry sheet on a lightly floured surface to about ⅛-inch thick and cut into 3-inch squares.
  • Place a tablespoon of the beef mixture in the center of each pastry square.
  • Fold the pastry over the filling to create a triangle or rectangle, sealing the edges by pressing with fingers or using a fork. Place on the prepared baking sheet.
  • Brush the tops of the pastries with the beaten egg for a golden finish.
  • Bake in the preheated oven for 20-25 minutes or until the pastries are golden and puffed.
  • Remove from oven and let cool for a few minutes before serving. Enjoy warm!

Notes

Ensure that the beef is cooked to your desired level of doneness. A meat thermometer can be used to check for a medium-rare temperature of 135°F (57°C).
You can substitute or add other ingredients like spinach or cheese for different flavor profiles.
These can be prepared ahead of time and frozen before baking; just add a few extra minutes to the baking time if baking from frozen.
