Instructions

  1. Step 1: Preheat oven to 375°F (190°C). Roll out 1 sheet puff pastry on a floured surface to a 12x10-inch rectangle. Transfer to a parchment-lined baking sheet and prick all over with a fork.
  2. Step 2: In a bowl, mix 1 cup thinly sliced spring onions, 1 cup fresh peas, 1/2 cup shredded Gruyère, and 1 tbsp chopped thyme. Spread evenly over the pastry, leaving a 1-inch border.
  3. Step 3: Whisk 1/4 cup heavy cream with 1 beaten egg until smooth. Pour over the filling, ensuring it seeps into the edges. Sprinkle with 2 tbsp all-purpose flour to prevent sogginess.
  4. Step 4: Bake for 25-28 minutes until pastry is golden brown and puffed, and filling is set. Let rest for 10 minutes before slicing to allow filling to set.
