Sourdough Discard Apple Galette: A Slice of Autumn Joy

There’s a certain kind of magic that happens when apples, cinnamon, and butter meet in the oven. The kitchen fills with warmth, the air turns sweet, and time seems to slow down — just a little.

This galette is one of those simple seasonal pleasures. It’s rustic and unfussy, made with ingredients you likely already have on hand — including sourdough discard, which gives the crust a lovely depth of flavor and a tender, flaky bite.

If you’ve been saving your discard and wondering what to do wit it — this is your sign. Bake it into something that smells like home.

Why you'll love it:

• A buttery, golden crust with real character (thanks, sourdough!)
• Juicy apple slices, gently spiced and sweetened.
• It’s incredibly easy to make — no mixer, no fancy tools, just your hands.
• Honestly? It’s even better than apple pie. Lighter, crispier, and so full of flavor.

Whether it’s a Sunday morning or a quiet Tuesday evening, this galette feels like a little celebration of fall. Especially when enjoyed warm, with a cup of tea or a scoop of vanilla ice cream.

Sourdough Discard Apple Galette Recipe:

For the Crust:

• 200 g all-purpose flour
• ½ tsp (about 3 g) salt
• 30 g sugar
• 156 g cold grated butter
• 237 g cold sourdough discard
  

For the Filling:

• 3 large apples, peeled, cored, and sliced
• 80 g sugar
• 1 tsp cinnamon
• A splash of vanilla
• 24 g melted butter

Extras:

• A bit of flour for rolling
• 1 beaten egg (for egg wash)
• Coarse sugar, for sprinkling
  

Instructions:

1. Make the Dough:

• In a large bowl, mix the flour, sugar, and salt.
• Add the cold grated butter. Use your hands to rub it into the flour until the mixture feels sandy.
• Pour in the cold discard and gently mix with your hands until it forms a rough dough.
• Knead just a few seconds to bring everything together.
• Place the dough on a floured sheet of parchment paper. Sprinkle a little more flour on top and roll it out slightly.
• Chill the dough (on the parchment) in the fridge for 30 minutes.

2. Prepare the Apples:

• Slice apples into ⅛–¼ inch slices.
• In a small bowl, stir together the melted butter, vanilla, and cinnamon.
• In a large bowl, toss the apple slices with sugar and the butter mixture using your hands until well coated.
  

3. Assemble the Galette:

• Once chilled, roll out the dough on the parchment to about ⅛ inch thick. Transfer to a baking sheet.
• Lightly dust with flour if sticky.
• Arrange the apple slices on the dough, leaving a 1½ inch border all around.
• Fold the edges over the apples in a rustic, crinkled shape.

4. Finishing Touches:

• Brush the folded crust with beaten egg.
• Sprinkle coarse sugar on the crust and over the apples.
• Chill the galette in the fridge while you preheat the oven to 355°F (180°C).

5. Bake & Enjoy:

• Bake for 55–65 minutes, or until golden brown and bubbling.
• Let it cool before slicing — and enjoy every bite 😋
  Perfect with tea, vanilla ice cream, or simply on its own.
