🍑 Golden Sourdough Discard Peach Galette — Flaky Crust, Juicy Peaches & Zero Pie Pan

🍑 Golden Sourdough Discard Peach Galette

Flaky crust. Juicy peaches. Zero pie pan required.

Makes 1 Galette (8 Slices)  •  Beginner Friendly  •  Discard-Powered  •  Ready in ~2 Hours (Mostly Chilling)

A sourdough discard peach galette is the dessert that looks like you spent all afternoon on it — and tastes like you did — but is secretly one of the easiest things you can bake with discard. No pie pan, no crimping, no lattice, no stress. Just a buttery, tangy crust folded up around a pile of juicy peaches, baked until the edges go deep golden and the filling bubbles.

If pie feels intimidating, a galette is your way in. It's rustic on purpose — the crooked folds are the whole charm. And that container of discard in your fridge? It's about to become the flakiest pastry you've ever made.

🍑 Sourdough Discard Peach Galette

Discard Pastry Crust

• 150 g all-purpose flour (about 1¼ cups), plus more for dusting
• 15 g granulated sugar (about 1 tbsp)
• 4 g fine sea salt (about ¾ tsp)
• 113 g cold unsalted butter (1 stick), cut into small cubes
• 120 g cold sourdough discard (about ½ cup, straight from the fridge)
• 30 g ice water (about 2 tbsp)

Peach Filling

• 450 g ripe peaches (about 4 medium), thinly sliced
• 80 g granulated sugar (about ⅓ cup + 1 tbsp)
• 15 g cornstarch (about 2 tbsp)
• 3 g ground cinnamon (about ½ tsp)
• 2 g fine sea salt (about ¼ tsp)
• 5 ml vanilla extract (about 1 tsp)
• 15 ml lemon juice (about 1 tbsp, freshly squeezed)

For Finishing

• 1 egg, beaten, for egg wash
• 25 g coarse turbinado sugar (about 2 tbsp), for sprinkling
• 28 g cold butter (about 2 tbsp), cut into small pieces, to dot over the filling

🥣 Step 1: Make the Discard Pastry

Whisk the flour, sugar, and salt together in a large bowl. Toss in the cold butter cubes and coat them in flour, then pinch and flatten the butter into the flour with your fingertips until you have a mix of pea-sized pieces and flat shards. Those flat shards are what make the crust shatteringly flaky — don't rub them out.

Stir the cold discard into the ice water, then pour it over the flour mixture. Mix with a fork just until a shaggy dough comes together. If a few dry bits remain, press them in with your hands — but stop the second it holds together. Overworked pastry is tough pastry.

Beginner Tip: Cold is everything here — cold butter, cold discard straight from the fridge, ice water. If your kitchen is warm, chill the bowl for 10 minutes before you start.

⏳ Step 2: Chill the Dough

Shape the dough into a flat disc, wrap it tightly, and chill for at least 1 hour (up to 2 days). This rest lets the flour hydrate and the gluten relax, and it keeps the butter solid so it steams into layers in the oven.

While the dough chills, slice your peaches. No need to peel them — the skins soften in the oven and add gorgeous color. Toss the slices with the sugar, cornstarch, cinnamon, salt, vanilla, and lemon juice, and let them sit for 10–15 minutes so the juices start to release.

🌀 Step 3: Roll & Assemble

Preheat the oven to 400°F (200°C) and line a baking sheet with parchment. On a lightly floured sheet of parchment, roll the chilled dough into a rough circle about 12–13 inches across and about ⅛ inch thick. Don't chase a perfect circle — rustic is the point.

Slide the parchment and dough onto the baking sheet. Arrange the peach slices in the center in overlapping spirals, or just pile them in — leaving a 2-inch border of bare dough all around. Dot the butter pieces over the filling. Spoon the slices on and leave most of the peach juices in the bowl — a dry crust bakes crisp, a flooded one bakes soggy.

Beginner Tip: Rolling on the parchment you bake on means you never have to transfer a floppy disc of dough. It's the single best galette trick there is.

🫓 Step 4: Fold the Edges

Fold the border up and over the peaches in loose pleats, working your way around the circle and letting the folds overlap naturally. The center stays open so the peaches can bubble and caramelize.

Brush the folded crust generously with beaten egg and shower it with the turbinado sugar. That sugar crust is what makes people think you bought it at a bakery. There is no wrong fold here — every galette looks different, and every single one looks homemade in the best way.

🔥 Step 5: Bake Until Golden & Bubbly

Bake for 35–40 minutes, until the crust is deep golden brown and the peach filling is bubbling thickly in the center. If the edges start browning faster than the center, tent the galette loosely with foil for the last 10 minutes.

Let it cool on the pan for at least 20 minutes before slicing. The filling needs that time to set — cut it hot and the juices run everywhere. Serve it warm with vanilla ice cream or a dollop of lightly sweetened whipped cream.

👩🍳 Squirrelly Girl Baker's Tips

🍑 1. Ripe but firm peaches win. They should give slightly when you press them but still hold their shape when sliced. Overripe peaches turn to mush in the oven.

🧈 2. Grate frozen butter for extra flakes. If you want the flakiest crust of your life, freeze the butter and grate it on a box grater straight into the flour. It distributes perfectly and stays cold.

🍋 3. Don't skip the lemon. It brightens the peaches, keeps the filling from tasting flat, and helps the cornstarch set the juices.

⏳ 4. Make the dough ahead. The wrapped disc keeps 2 days in the fridge or 3 months in the freezer. Thaw overnight in the fridge and you're 10 minutes from assembly.

🍯 5. Love the crust? Double it. This same discard pastry is the base for our flaky sourdough discard pie crust — one dough, endless desserts.

🧊 Make It Ahead

The baked galette keeps up to 2 days at room temperature under a loose cover, or up to 4 days in the fridge in an airtight container.

To freeze, cool the baked galette completely, wrap it tightly in plastic wrap and foil, and freeze for up to 2 months. Thaw overnight in the fridge.

Reheat like this: warm slices in a 325°F oven for 8–10 minutes until the crust crisps back up. The microwave will warm it but the crust goes soft — the oven is worth it.

🚨 Peach Galette Troubleshooting

My crust came out soggy underneath.

The peaches gave off too much juice, or the galette went in on a cool baking sheet. Next time, hold back the peach juices when assembling, and bake on a preheated baking sheet for extra bottom heat.

The crust shrank and the filling leaked out.

The dough wasn't chilled long enough, or it was overworked. Chill a full hour, handle it gently, and make sure your folds overlap so there are no gaps.

My peaches are still firm after baking.

They were underripe. Give the galette another 5–10 minutes in the oven, tented with foil so the crust doesn't over-brown. Next time, choose peaches that give slightly when pressed.

The filling is too runny.

Either the cornstarch was skipped or the galette was sliced too soon. Let it cool a full 20 minutes so the juices set, and don't reduce the cornstarch — it's doing real work.

⚠️ Baker's Warning

Making a sourdough discard peach galette has a predictable side effect.

Suddenly you're the person who "just whipped up a galette."

People will ask for the recipe. People will ask you to bring dessert. People will assume you own a pie dish and know what a lattice is.

You're officially the galette person.

❓ FAQ: Sourdough Discard Peach Galette

Can I use active starter instead of discard?

Yes — active starter works the same way in the crust. Discard is the better choice here, though: it's cold from the fridge, which keeps the butter solid, and it would otherwise go to waste.

Can I make this galette with frozen peaches?

Yes. Thaw them completely and drain off the excess liquid before tossing with the sugar and cornstarch. You may need an extra teaspoon of cornstarch since frozen fruit releases more juice.

Why is my galette crust tough instead of flaky?

Two usual suspects: the dough was overworked, or the butter got too warm. Mix just until it holds together, keep everything cold, and chill the disc a full hour before rolling.

Can I make the dough ahead of time?

Absolutely — the wrapped disc keeps 2 days in the fridge or 3 months in the freezer. Thaw frozen dough overnight in the fridge before rolling.

What should I serve with a peach galette?

Vanilla ice cream is the classic move, and lightly sweetened whipped cream is a close second. A drizzle of honey or a brush of warm peach preserves over the top makes it look straight from a bakery case.
