Ingredients

Chicken and Mushroom Filling

  • 1 lb boneless, skinless chicken thighs or breasts, diced
  • 2 tbsp olive oil
  • 1 small onion, finely chopped
  • 2 garlic cloves, minced
  • 8 oz mushrooms, sliced
  • 2 tbsp all-purpose flour
  • 1/2 cup dry white wine (optional)
  • 1 cup chicken broth
  • 1/2 cup heavy cream
  • 1 tsp Dijon mustard
  • 1 tsp fresh thyme (or 1/2 tsp dried)
  • Salt and black pepper, to taste

Pie Assembly

  • 1 sheet puff pastry, thawed
  • 1 egg, beaten (for egg wash)

Instructions

  1. Sauté the Aromatics: Preheat the oven to 400°F (200°C). In a large skillet, heat olive oil over medium heat. Add the finely chopped onion and minced garlic, sautéing until soft and fragrant to form the flavor base.
  2. Cook the Mushrooms and Chicken: Add sliced mushrooms to the skillet and cook until nicely browned to deepen their flavor. Then, stir in diced chicken pieces and cook until lightly golden and no longer pink inside.
  3. Thicken the Sauce: Sprinkle flour over the mixture, stirring constantly for about a minute to create a roux. Gradually add dry white wine, chicken broth, and heavy cream, stirring until smooth and thickened to a creamy consistency.
  4. Add the Final Touches: Stir in Dijon mustard and fresh thyme. Season with salt and black pepper to taste. Let the mixture simmer gently for 5 minutes to meld the flavors, then remove from heat and allow to cool slightly.
  5. Assemble and Bake: Transfer the cooled filling into a pie dish. Cover with the thawed puff pastry sheet, trimming and crimping edges to seal. Cut a small slit in the center to vent steam. Brush pastry with beaten egg for a golden finish. Bake for 25–30 minutes until puffed and golden brown. Let rest 5 minutes before serving.

Notes

  • Use chicken thighs for juicier filling or breasts for leaner pie.
  • Dry white wine enhances flavor but can be omitted or replaced with more chicken broth.
  • Allow filling to cool before adding pastry to prevent sogginess.
  • Egg wash ensures a shiny, golden pastry crust.
  • Fresh thyme brings brighter flavor; dried thyme works well as a substitute.
  • Make sure to vent the pastry to avoid steam buildup during baking.
