  • Total Time: 40 minutes
  • Yield: 24 pieces

Ingredients

For the Beef Pieces:

  • 1 pound beef tenderloin (450 grams)
  • ½ teaspoon salt
  • ¼ teaspoon black pepper (or to taste)
  • 1 tablespoon olive oil

For the Mushroom Filling:

  • 1 tablespoon olive oil
  • ½ onion, minced
  • 2 cups button mushrooms, finely chopped (about 7 ounces / 200 grams)
  • 1 tablespoon regular soy sauce
  • Generous pinch of black pepper
  • 1 teaspoon dried oregano
  • ½ cup pitted black olives (60 grams)

For the Beef Wellington Bites:

  • 1 pound puff pastry (450 grams)
  • Mustard (to taste)
  • 1 small egg, beaten

Instructions

  1. Prepare the Beef: Cut the beef tenderloin into 1-inch (2.5 cm) pieces and season with salt and black pepper. Heat 1 tablespoon olive oil in a skillet over high heat. Brown half of the beef pieces on all sides for 1-2 minutes. Transfer to a plate lined with paper towels. Repeat with the remaining beef pieces and set aside.
  2. Make the Mushroom Filling: In the same skillet, heat 1 tablespoon olive oil over medium-low heat. Add the minced onion and chopped mushrooms, sautéing for 10 minutes while stirring occasionally until softened. Add soy sauce, dried oregano, and a generous pinch of black pepper, stirring to combine.
  3. Process the Filling: Transfer the mushroom mixture to a food processor. Add pitted black olives, ensuring no stones remain. Pulse until the mixture reaches a smooth-ish consistency.
  4. Assemble the Wellington Bites: Preheat the oven to 400°F (200°C). Unfold or unroll the puff pastry sheet and cut into approximately 3-3.5 inch (8-9 cm) squares. Spread a small amount of mustard in the center of each square, then top with a spoonful of the mushroom filling followed by a piece of browned beef. Fold two opposite corners over the filling and beef, then fold the other two corners, pressing to seal tightly.
  5. Prepare for Baking: Place each parcel on a baking tray lined with baking parchment. Brush the tops of each pastry parcel with the beaten egg to achieve a golden finish.
  6. Bake: Bake in the preheated oven for 10-15 minutes, or until the puff pastry is risen and golden brown. Serve warm with your choice of dipping sauce.

Notes

  • Use beef tenderloin for the best tenderness and flavor.
  • Adjust salt according to taste and dietary needs.
  • Finely chopping mushrooms helps them cook evenly and blend smoothly in the filling.
  • Keep puff pastry chilled until ready to use to ensure flakiness.
  • Mustard adds a subtle tang that complements beef and mushrooms well.
  • Use a lined baking tray to prevent sticking and make clean-up easier.
  • Ensure the pastry corners are well sealed to prevent filling from leaking during baking.
