Ingredients:
- All-Purpose Flour: 300g
- Unsalted Butter (very cold, cubed): 150g
- Ice Water: 60ml – 80ml
- Fine Sea Salt: ½ tsp (3g)
- Mixed Mushrooms (chopped): 300g
- Shallots (finely diced): 2 large
- Garlic (minced): 2 cloves
- Fresh Thyme leaves: 1 tsp
- Vegetable or Beef Stock: 120ml
- Worcestershire Sauce: 1 tsp
- Cornflour (Cornstarch): 1 tbsp
- Cold Water (for slurry): 2 tbsp
- Olive Oil: 1 tbsp
- Black Pepper: To taste
- Egg (for wash): 1 large
- Water (for wash): 1 tsp
- Sesame Seeds or Coarse Sea Salt: For topping (optional)
Instructions:
- Combine flour and salt in a food processor. Add the cold, cubed butter and pulse until the mixture resembles coarse breadcrumbs with pea-sized chunks of butter remaining.
- Gradually add the ice water while pulsing until the dough just starts to come together. Turn dough onto plastic wrap, shape into a flat disc, wrap tightly, and chill for at least 30 minutes.
- Heat olive oil in a pan over medium heat. Sauté shallots until soft (about 4 minutes). Add garlic and thyme; cook for 1 minute until fragrant.
- Increase heat slightly and add mushrooms. Cook until they release their liquid and the liquid evaporates. Add stock and Worcestershire sauce, bring to a gentle simmer.
- Whisk the cornflour with 2 tbsp cold water to create a slurry. Stir the slurry into the mushroom mixture and cook until the filling thickens significantly. Season with pepper and allow the filling to cool completely.
- Preheat the air fryer to 375°F (190°C). On a lightly floured surface, roll the chilled dough out to about 1/8-inch (3mm) thickness.
- Use a 4-inch cutter to stamp out 16 circles. Brush the edges of 8 circles lightly with the egg wash. Place 1-2 tablespoons of cooled filling onto one half of each circle.
- Fold the empty side over to create a half-moon. Crimp the edges firmly using a fork to create a secure seal.
- Brush the tops of all pies with the remaining egg wash and sprinkle with sesame seeds or salt, if using. Cut 2 small slits on top of each pie to allow steam to escape.
- Place pies in the air fryer basket in a single layer (work in batches). Cook for 12–15 minutes, flipping halfway through, until the pastry is deep golden brown and crisp. Let rest for 5 minutes before serving.
