Method
Make the galette dough
- Whisk all-purpose flour, granulated sugar, and fine salt in a large bowl until evenly combined.
- Add cold unsalted butter cubes and use your fingertips to press and smear the butter into the flour until the mixture looks shaggy with pea-sized butter pieces remaining.
- Add ice-cold water 1 tablespoon at a time, stirring with a fork after each addition, until the dough just comes together and holds when pinched but does not feel wet.
- Do not overwork the dough, then turn it onto a lightly floured surface and pat into a disk.
- Wrap the disk in plastic wrap and refrigerate at least 1 hour (up to 2 days) to firm the butter.
Prep the filling and assemble
- Preheat the oven to 400°F (205°C) and line a large baking sheet with parchment paper.
- Toss peach slices with granulated sugar, brown sugar, cornstarch, fresh lemon juice, pure vanilla extract, cinnamon, and salt, then let sit for 10 minutes.
- Remove the dough from the fridge and roll it out on a lightly floured surface into a rough 12-inch circle about 1/8-inch thick.
- Transfer the rolled dough to the prepared baking sheet.
- Arrange the peach slices in the center of the dough in overlapping concentric circles or a casual fanned pattern, leaving a 2-inch border.
- Dot the peach filling with the small pieces of unsalted butter.
- Fold the edges up and over the outer ring of peaches, pleating as you go, then press gently to seal the folds.
- Brush the folded crust edge with egg wash and sprinkle generously with coarse sugar.
Bake and finish
- Bake at 400°F (205°C) for 38–42 minutes, until the crust is deep golden brown and the peach juices are bubbling and slightly thickened.
- Remove from the oven and cool on the pan for at least 20 minutes before slicing.
- Optional: warm apricot jam with water, then brush lightly over the warm peaches for a glossy finish.
Notes
Pro tip: keep the butter cold—if the dough feels soft while rolling, chill it 10–15 minutes so the crust bakes flaky. Store baked peach galette covered in the refrigerator up to 3 days; rewarm in a 350°F oven for 8–10 minutes. Freezing: wrap slices and freeze up to 2 months, then reheat from thawed. For a dairy-free swap, use a 1:1 cold vegan butter alternative in the dough and dot-butter.
