01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper.
02 - Unroll the puff pastry onto the prepared baking sheet. Score a 0.5-inch border around the edges, being careful not to cut all the way through. Prick the pastry inside the border with a fork.
03 - In a bowl, mix crème fraîche, goat cheese, egg, parmesan, lemon zest, salt, and pepper until smooth.
04 - Spread the cheese mixture evenly over the pastry, keeping within the scored border. Arrange the asparagus spears and spring onions on top. Brush asparagus lightly with olive oil and season with additional salt and pepper.
05 - Bake in the center of the oven for 22–25 minutes, or until the pastry is golden and crisp, and the asparagus is tender.
06 - Remove from the oven, let cool for 5 minutes, then garnish with fresh herbs and serve with lemon wedges if desired.
