I love making galettes because they are so rustic and freeform. And when it’s the middle of summer and you want to spend less time in the kitchen and less time with the oven on, they are the perfect dessert to bake!
This is another collab recipe with my friend Hannah at Make It Dough! We use sourdough discard in this pie crust, so you will learn how to make pie dough with sourdough discard. Spoiler, it’s the easiest thing in the world! Plus, you get to use up discard and get a little sourdough flavor in your pie crust – it’s a win win!
Fresh peaches are gently tossed with a mix of sugar, flour, and cornstarch, and I also add a little bit of cinnamon to mine as I always add cinnamon into peach pie! Hannah makes hers without, so you can go either way on the cinnamon.
I use my favorite honey and water pie wash, in lieu of traditional egg wash. I started doing this when I was writing my book Effortless Eggless Baking and it has become my absolute favorite way to get a golden brown pie crust! It has a slightly sweeter taste than traditional egg wash, but I’m all about that sweetness!
Why You'll Love This Recipe
Uses Sourdough Discard: I love using sourdough discard in recipes because it takes something that would have been waste and turns it into something delicious! This is one of my favorite things about using sourdough discard.
Sweet & Tangy: The addition of sourdough discard on the pie crust makes for a sweet and tangy flavor that only sourdough can provide. I love how perfectly this pairs with the fresh peaches.
Easy AF: I love galettes because they are literally lazy girl pies. It's a pie without the dish, that's the only difference! So, it makes it much easier to make as you don't have to form the dough into the dish or top it. I also prefer galettes to pies because the crust ends up being even more crispy because it bakes right on the sheet pan! No soggy bottoms ever when you make a galette.

Step by Step Instructions
Step 1
To make the crust: In a small bowl, add the cold water and sourdough discard and stir with a fork to dissolve the discard into the water. Set aside.
Step 2
To make the dough: In the bowl of your stand mixer fitted with the paddle attachment, add the flour and cold cubed butter. Turn the mixer on low and slowly start to incorporate the ingredients. Gradually turn the mixer to medium speed. Once the butter mixture looks like wet sand, immediately add in all the water and sourdough mixgture. As soon as the dough comes together, stop the mixer. Do not over mix.
Alternatively, if you are not using your mixer, then you make this by hand as well using these instructions:
In a medium bowl, add the flour and cubed butter. Work the butter in using your fingertips or a pastry blender until all of the flour is coated in fat.
Make a well in the center and pour the starter mixture in. Mix with a spatula or wooden spoon until the dough comes together. Lightly knead the dough until a shaggy dough forms, don’t overwork the dough, it’s okay if there are a few dry bits remain.
Step 3
Turn the dough on a large piece of plastic wrap. Gather the dough together using the edges of the plastic wrap, this prevents your dough from heating up and the butter from melting.
Flatten the dough into a disc and wrap it tightly in plastic. Refrigerate the dough for at least 4 hours, or overnight.
Step 4
Preheat the oven to 400°F. Line a baking sheet with parchment paper.
Step 5
To make the filling: In a large bowl, add the cane sugar, flour, cornstarch, and cinnamon and whisk together. Set aside.
Step 6
Pit and slice the peaches and add to the sugar mixture.
Step 7
To make the topping: In a small bowl, add the honey and water and microwave for 10 seconds to melt the honey. Set aside.
Step 8
Remove the pie dough from the fridge. Remove the plastic wrap and place on a floured surface. Roll out the into a square that is 1/4-inch thick, it should be about 12 inches diameter.
Step 9
Arrange the filling in the center of the chilled dough and spread it evenly, leaving a 2-inch border. Fold the edges of the dough up over the fruit. Brush the dough with honey wash and sprinkle the turbinado sugar on top. Place dots of butter on top of the filling.
Step 10
Bake for 35 to 40 minutes or until the crust has browned and the filling looks bubbly. Allow the galette to cool for at least 20 minutes before slicing and serving. (Be sure to check the recipe Notes for high altitude baking!)
FAQ's
No, you don’t need a mixer. You can make pie dough with or without a mixer and we provide instructions for both!
Cornstarch is a thickening agent, and it is used in pie fillings to thicken the fruit juices that get created when the sugar melts and the fruit cooks. If you don’t want to use cornstarch you can also use tapioca starch or Irish moss powder, both of which are also thickeners.
Flour is also a thickening agent and it works with the cornstarch to bind the sugars that are created in the oven as the pie bakes. I use cornstarch and flour here because using too much flour can result in a flour taste in the filling, which we don’t want!
No, you don’t need to add the turbinado sugar to the crust. This is optional, but it is what gives pie crust that sparkly look and it provides an amazing texture and little crunch! Regular cane sugar will not do the same thing as it will evaporate into the pie crust because the it is so much finer.
Galettes, just like pies, are best when eaten right away. But you can store it in a cool dry place for up to 3 days. Don’t put it in an airtight container as it will become soggy. You can always re-heat a galette very easily in your oven or toaster oven and it will crisp right up! Never microwave it as you will have a soggy disaster!
