Ever since I learned what a galette is (a rustic, freeform tart/pie), I have been in love! I am someone who doesn’t like dry things, and lets face it, sometimes a pie is dry. Well not with a galette, especially this rustic berry peach galette! The sourdough crust is just the right amount of flaky and buttery and when folded over to hold in the fruit you get the thick bites that are the perfect texture of soft and substantial. This Berry Peach Galette is easy to make, versatile, and perfect for using fresh or frozen fruit (the peaches take this to the next level!).

Why You’ll Love This Rustic Berry Peach Galette

• Flaky and buttery crust – thanks to the sourdough discard and greek yogurt. Hello a little added protein!
• Naturally sweetened fruit filling – bursting with flavor from berries and peaches. Berries alone would be great too, but the peaches add so much to the flavor!
• Easier than pie – no need for a pie pan or precise crimping. Yea for easier!
• Customizable – use fresh or frozen fruit, mix up the fruit, it is up to you!

Ingredients & Substitutions

Sourdough Galette Crust:

• Flour – I like to use organic all-purpose flour to skip the chemicals that is often sprayed on conventional wheat making it sprout sooner.
• Butter – grating cold butter ensures a flaky texture and is a whole lot easier! You do not need it frozen, just cold.
• Sugar & salt – enhances flavor. Organic cane sugar is my go to!
• Greek yogurt – adds tenderness. Organic if possible, and full fat or non-fat. It is up to you!
• Sourdough starter discard – gives a slight tang and improves texture. If you don’t have a sourdough starter use this galette crust recipe (it is super delicious as well!)

Berry Peach Filling:

• Mixed berries and peaches – fresh or frozen work well. I use frozen as they are less expensive!
• Arrowroot powder – thickens the filling naturally.
• Organic Cane sugar – balances the fruit’s tartness.

For Topping:

• Egg wash – gives a golden, crisp crust.
• Turbinado sugar – adds a crunchy, caramelized finish. And it is super yummy!

   • Roll out the dough into a rustic circle about 15 inches in diameter.
   • Add fruit filling in the center, leaving a border.
   • Fold the edges over, pleating as needed.

Expert Tips for the Best Galette
