01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper.
02 - Lay the puff pastry sheet on the prepared baking sheet. Score a ½-inch border around the edges with a sharp knife, being careful not to cut all the way through. Prick the center area with a fork.
03 - In a bowl, mix together the crème fraîche, goat cheese, egg, minced garlic, lemon zest, salt, and pepper until smooth. Spread evenly over the center of the pastry, keeping within the scored border.
04 - Toss the asparagus, sugar snap peas, carrots, radishes, and zucchini with olive oil, a pinch of salt, and pepper.
05 - Arrange the vegetables in a single layer over the cheese mixture.
06 - Bake for 25–30 minutes, or until the pastry is golden and crisp and the vegetables are just tender.
07 - Remove from the oven. Drizzle with lemon juice and sprinkle with fresh herbs and cracked pepper. Let cool slightly before slicing and serving.
