Zucchini and Egg Tart With Fresh Herbs

Step 1

Heat the oven to 425 degrees. Beat one egg in a small bowl for egg wash.

Step 2

On an inverted baking sheet, unfold the puff pastry to lay it out flat. Cut the puff pastry into a 10-by-12-inch rectangle, rolling out and trimming excess as needed. Slice a 3/4-inch strip from the perimeter of the puff pastry from each of the four sides. Brush the remaining puff pastry with the egg wash then prick every few inches of the surface with a fork to prevent puffing. Place the pastry strips along the edge of all four sides to form a border that is raised like the edges of a picture frame, gently pressing to seal. Trim the excess and brush border with egg wash.

Step 3

On a second baking sheet, gently toss the zucchini and scallions with 1 tablespoon oil; season with salt and pepper. Transfer both baking sheets to the oven (the sheet holding the puff pastry should still be inverted) and bake until vegetables are softened and pastry is puffed and golden, removing the vegetables after 10 minutes and the puff pastry after 20 to 25 minutes. Press the pastry’s puffed center gently with your fingertips to deflate.

Step 4

Stir the crème fraîche, mustard and lemon zest in a small bowl and season with salt and pepper. Working within the border, brush the mixture over the pastry. Halve the zucchini crosswise at an angle. Arrange the zucchini and scallions on the surface of the pastry, draping the zucchini on its side and reinforcing with the scallions to create four circular nests to hold the eggs.

Step 5

Crack each of the remaining four eggs into a small cup then transfer to a nest in the puff pastry. In a small bowl, toss the peas with the remaining 1 teaspoon oil and season with salt and pepper. Avoiding the eggs, sprinkle the tart with the peas. Bake until the egg whites are opaque and custardy and yolks are still runny, about 20 minutes. Season the eggs with salt and pepper and top with torn fresh herbs. Cut the tart into quarters and serve immediately.
