Method
Preheat the oven to 230°C (450°F) with a rack in the center. Line a sheet pan with foil.
Heat the olive oil in an ovenproof skillet over medium-high heat. Sauté the leek, garlic, and fennel for 3 minutes until softened.
Add the potatoes, asparagus, salt, and black pepper to the skillet. Stir to combine.
Dust the vegetables with flour and cook for 1 minute while stirring to coat.
Stir in the vegetable stock, sour cream, chives, Dijon mustard, and Gruyère. Remove the skillet from the heat once the cheese begins to melt.
Roll the puff pastry on a floured surface until it is 3-5cm (1-2 inches) wider than the skillet.
Place the pastry over the filling. Trim excess and tuck the edges inside the skillet rim.
Brush the top of the pastry with the beaten egg and cut small slits to vent steam.
Place the skillet on the sheet pan and bake for 20-25 minutes at 230°C (450°F).
Remove from the oven and let the potpie rest for 10 minutes before serving.
Chef's Notes
- Ensure your leeks are thoroughly washed to remove any grit, as they can trap dirt between their layers. Slice them thinly for even cooking.
- Don't skip the step of dusting the vegetables with flour and cooking it for a minute; this is crucial for thickening the sauce and preventing a watery filling.
- When rolling out puff pastry, keep it cold. If it gets too warm, the layers can meld together, resulting in a less flaky crust.
- For an extra golden and crisp crust, you can lightly sprinkle the puff pastry with a little extra grated Gruyère before baking.
- Allowing the potpie to rest for 10 minutes after baking is essential for the filling to set, preventing it from being too runny when served.
Storage
Refrigerator: 3 days — Store in an airtight container; pastry will lose crispness.
Freezer: 1 month — Freeze before baking for best results.
Reheating: Reheat in a 175°C (350°F) oven until the center is hot and pastry is recrisped.
