Ingredients

Scale
  • 8 oz beef tenderloin, trimmed and cut into 1-inch cubes
  • 1 tbsp olive oil (extra virgin preferred)
  • 2 tbsp unsalted butter, softened
  • 8 oz cremini mushrooms, finely chopped
  • 1 small shallot, minced
  • 2 cloves garlic, minced
  • 1 tsp fresh thyme, chopped (or ½ tsp dried thyme)
  • 1 sheet puff pastry (about 8x8 inches), thawed
  • 1 tbsp Dijon mustard
  • 1 large egg yolk, beaten
  • Salt and freshly ground black pepper, to taste
  • Flour, for dusting work surface

Instructions

  1. Pat the beef cubes dry with paper towels and season generously with salt and pepper.
  2. Heat olive oil in a skillet over medium-high heat and sear beef cubes for about 1 minute per side until browned but not cooked through. Remove and let cool.
  3. In the same skillet, add softened butter. Add chopped mushrooms, shallots, garlic, and thyme. Cook over medium heat, stirring frequently, until mixture is dry and fragrant, about 8–10 minutes. Season with salt and pepper. Remove from heat and let cool. Optionally pulse in a food processor for a smoother texture.
  4. Lightly flour your work surface and roll out the thawed puff pastry sheet to about 9×9 inches. Cut into 12 equal squares (about 3×3 inches).
  5. Preheat oven to 400°F (200°C). Brush each pastry square lightly with Dijon mustard.
  6. Place a spoonful of mushroom duxelles in the center of each square, top with a seared beef cube.
  7. Fold pastry corners up over the beef, pinching edges to seal and form a neat package. Place seam-side down on a parchment-lined baking sheet.
  8. Brush tops with beaten egg yolk for a golden finish. Optionally score tops lightly with a knife without cutting through.
  9. Bake for 15–18 minutes until pastry is puffed and golden brown.
  10. Let rest for 5 minutes before serving. Garnish with fresh thyme or flaky sea salt if desired.
