This peach tart with puff pastry starts with one sheet of dough, four ripe peaches, and about fifteen minutes of hands-on prep before it goes into the oven. The pastry puffs up around the fruit in about twenty-five minutes, turning deep gold at the edges while the peach juices thicken into a light glaze.
1largeegg - beaten with 1 tablespoon water, for egg wash
2tablespoonsturbinado sugar - 25 g, for the crust edges
2tablespoonsapricot preserves - 40 g, warmed, for the finishing glaze
Instructions
Preheat the oven to 400°F (200°C). Line a rimmed baking sheet with parchment paper and set aside.
In a mixing bowl, combine sliced peaches, granulated sugar, lemon juice, cornstarch, cinnamon, vanilla, and salt. Toss gently to coat and let sit for 5 minutes.
Unfold the thawed puff pastry onto the lined baking sheet. Score a line ¾ inch from the edge on all sides, cutting halfway through. Prick the center area with a fork.
Drain excess liquid from the peaches. Arrange slices in overlapping rows inside the scored border, leaving the border bare. Spoon any remaining juice over the top.
Whisk the egg with 1 tablespoon water. Brush the egg wash only along the outer border of the pastry. Sprinkle turbinado sugar over the border.
Bake on the middle rack for 22 to 25 minutes, until the border is puffed and deep golden brown and the juices are bubbling. Rotate halfway through for even browning.
Warm the apricot preserves until loose. Strain if desired, then brush a thin layer over the warm peaches. Cool on the pan for at least 10 minutes before slicing.
Notes
Keep puff pastry cold until filling to ensure even puffing.
Slice peaches consistently ¼ inch thick for even cooking.
Don't skip the cornstarch—it thickens the peach juices into a glaze.
Drain excess liquid from the peaches before arranging to avoid a soggy center.
Score the border without cutting all the way through for a raised rim.
If your peaches are very juicy, add an extra teaspoon of cornstarch.
Bake on the middle rack to ensure the bottom browns evenly.
Check at the 18-minute mark if your oven runs hot to prevent over-browning.
Use peaches that give slightly near the stem for the best flavor and texture.
Let peaches sit in sugar for no more than 10 minutes to avoid excess liquid.
A pizza cutter makes clean slices once the tart has cooled slightly.
Store leftover tart loosely covered at room temperature for up to 1 day or refrigerated for up to 3 days.
Reheat in a 350°F oven for 5-7 minutes to re-crisp the pastry; avoid microwaving.
