Ingredients Method Notes

Ingredients
  

  • 1 lb beef tenderloin or filet mignon cut into small cubes
  • 1 tbsp olive oil
  • Salt and pepper to taste
  • 1 cup mushrooms finely chopped
  • 2 tbsp shallots minced
  • 2 cloves garlic minced
  • 1 tbsp fresh thyme or 1 tsp dried
  • 1 package puff pastry thawed
  • 1 egg beaten (for egg wash)
  • 1 tbsp Dijon mustard optional
  • Flour for dusting

Method
 

  1. Sear the Beef: Heat olive oil over medium-high heat. Season beef with salt and pepper, then sear for 2–3 minutes per side until browned but still rare inside. Set aside to cool completely.
  2. Prepare the Mushroom Duxelles: In the same pan, cook mushrooms, shallots, and garlic for 5–7 minutes until moisture evaporates. Stir in thyme, season, and cool completely.
  3. Roll the Puff Pastry: On a floured surface, roll out puff pastry to 1/8-inch thickness. Cut into 3×3-inch squares.
  4. Assemble: Place 1 tsp mushroom duxelles and a cube of beef on each pastry square. Fold into parcels and seal edges with a fork. Chill for 15 minutes.
  5. Bake: Brush with egg wash and bake at 400°F (200°C) for 15–20 minutes until golden brown and puffed.
  6. Serve: Cool slightly before serving. Serve warm with horseradish cream, Dijon mustard, or red wine reduction.

Notes

Chill the assembled bites before baking to prevent pastry shrinkage. Use high-quality puff pastry and tenderloin for best results. Serve immediately for maximum crispness and flavor.
