👨‍🍳

Instructions

1

Heat the oven to 400°F (200°C). Roll the puff pastry into a 10-inch round and keep chilled while you make the filling.

2

Melt the butter with the olive oil in a large skillet over medium heat. Add the leeks, carrots, and celery with a pinch of salt and cook until softened, about 6 minutes.

3

Add the mushrooms and cook until they release their moisture and begin to brown, 8 to 10 minutes. Stir in the garlic and thyme for 30 seconds.

4

Sprinkle in the flour and cook for 1 minute. Whisk in the broth, milk, and tamari; simmer until the sauce is thick enough to coat a spoon, 4 to 5 minutes.

5

Stir in the peas and season with the remaining salt and pepper. Transfer the filling to a 9-inch pie dish.

6

Lay the puff pastry over the filling, trim the edges, and crimp. Cut a few vents and brush with the beaten egg.

7

Bake until the crust is deep golden and the filling is bubbly, 25 to 30 minutes. Rest 10 minutes before serving.

💡

Chef Tips

  • Let the filling cool slightly before topping so the pastry stays crisp.
  • For extra depth, add 1/2 teaspoon smoked paprika with the thyme.
  • Place the pie dish on a sheet pan to catch any bubbling sauce.

FAQ

Can I make the filling ahead?

Yes, the filling keeps for up to 2 days in the fridge. Rewarm before assembling so it spreads evenly.

What can I use instead of puff pastry?

Use a pie crust or a sheet of phyllo brushed with butter for a lighter topping.
