There’s something timeless about peach cobbler baking in the oven: sweet fruit bubbling at the edges, a golden topping crackling under the spoon, and the kitchen filled with the soft perfume of summer. This sourdough peach cobbler takes that familiar comfort and adds a gentle tang from sourdough discard, giving the topping depth without overpowering the fruit.

It’s the kind of dessert you make when peaches are ripe on the counter and your sourdough jar is ready to be fed again. No fancy techniques, no waste: just honest, from-scratch baking that belongs in a well-loved recipe box.

Why Use Sourdough Discard in Peach Cobbler?

Sourdough discard is perfect for cobblers because it adds:

• A subtle tang that balances sweet peaches
• Moistness and tenderness to the topping
• A simple way to reduce food waste
• Depth of flavor without long fermentation

This recipe does not require active sourdough starter; discard straight from the fridge works beautifully.

Ingredients You’ll Need

For the Peach Filling

• 6–7 cups sliced fresh peaches (or frozen, thawed and drained)
• ½ cup organic cane sugar
• 1 tablespoon lemon juice
• 1 teaspoon vanilla extract
• 1 teaspoon ground cinnamon
• ¼ teaspoon nutmeg (optional)
• 1 tablespoon arrowroot powder or cornstarch

For the Sourdough Cobbler Topping

• 1 cup all-purpose flour (or freshly milled soft wheat)
• ½ cup sourdough discard (unfed)
• ⅓ cup organic cane sugar or coconut sugar
• 1 teaspoon baking powder
• ½ teaspoon baking soda
• ½ teaspoon unrefined salt
• 6 tablespoons cold butter, cut into cubes
• ¼ cup whole milk or buttermilk
• Optional: blackberries for topping

How to Make Sourdough Peach Cobbler

Step 1: Prepare the Peaches

Preheat your oven to 375°F.

In a large bowl, combine the sliced peaches, sugar, lemon juice, vanilla, cinnamon, nutmeg (if using), and arrowroot powder. Gently toss until the peaches are well coated.

Pour the mixture into a greased 9×13-inch baking dish or large cast iron skillet.

Step 2: Make the Sourdough Cobbler Topping

In a separate bowl, whisk together the flour, sugar, baking powder, baking soda, and salt.

Cut in the cold butter using a pastry cutter or your fingertips until the mixture resembles coarse crumbs.

Stir in the sourdough discard and milk just until combined. The dough should be thick and spoonable: rustic, not smooth.

Step 3: Assemble the Cobbler

Drop spoonfuls of the sourdough topping evenly over the peaches. Leave small gaps so the fruit can bubble up around the edges.

Step 4: Bake

Bake uncovered for 40–45 minutes, or until the topping is golden brown and the peach filling is bubbling thickly around the sides.

If the topping browns too quickly, loosely cover with foil during the last 10 minutes.

Step 5: Cool and Serve

Let the cobbler cool for 10–15 minutes before serving. This allows the juices to thicken and the flavors to settle.

Serve warm with:

• Homemade vanilla ice cream
• Fresh whipped cream
• A drizzle of raw cream or honey
• Blackberries

Tips for the Best Sourdough Peach Cobbler

• Fresh peaches give the best texture, but frozen work well in winter.
• If your sourdough discard is very tangy, add an extra tablespoon of sugar to the topping.
• For a crispier top, sprinkle coarse sugar over the dough before baking.
• This recipe also works beautifully with nectarines or a peach-berry blend.

Make-Ahead & Storage

• Store leftovers covered in the refrigerator for up to 4 days.
• Reheat in the oven at 325°F for best texture.
• This cobbler can be assembled ahead and baked fresh the same day.
