Preparation
- Preheat oven to 400°F (200°C).
- Melt butter in a large skillet over medium heat.
- Sauté onions, carrots, and celery for 6 minutes until soft.
- Stir in potatoes and cook for 5 minutes.
- Sprinkle flour over vegetables and stir constantly for 2 minutes.
- Gradually whisk in vegetable broth until thickened.
- Stir in heavy cream, thyme, salt, and pepper; simmer until sauce coats a spoon.
- Fold in peas and remove from heat.
- Transfer filling to a deep ceramic baking dish.
- Drape puff pastry over the dish, trim edges, and brush with beaten egg.
- Bake for 25 minutes until the crust is golden brown.
Notes
Keep pastry cold until the last second to ensure maximum puff. Let the pie rest for 10 minutes before serving so the sauce thickens.
