FAQ's

Can I use unsalted butter?

Yes, if you only have unsalted butter and would like to use that, just add in a heaping 1/4 teaspoon of salt into the flour and sugar step.

What size pie can I make with this Sourdough Pie Crust recipe?

This Sourdough Pie Crust recipe will make one 9-inch pie double crust (top and bottom) by separating dough into disks that weigh about 200 grams and 300 grams.

Or you can make 2 galettes, separate into 2 disks that weigh about 250 grams each.

Or you can make 5 mini galettes, separate dough into 5 portions that weigh about 100 grams each and form into disks.

With pie crust, you always need to form your dough into the amounts you need before chilling. You want to work the dough as little as possible once it’s chilled to make sure it retains that buttery and flaky crust. So, you don’t want to be cutting up or adding pieces of dough to make up the portions you need, it’s not like cookie dough where you can easily do that! So, it must be done ahead of time before chilling.

Do I need a mixer for this recipe?

No, you don’t need a mixer to make this Sourdough Pie Crust! You can use a mixer, or you can also just use a bowl and your hands. I give directions for both ways in the recipe. While you can always make pie crust with your hands, making it in a mixer is so much faster and it’s how I prefer to do it.

How long will Sourdough Pie Crust last?

This Sourdough Pie Crust should be made 24 hours in advance of when you plan to use it, as it does need to chill in the fridge. If you aren’t going to use it right away, then freezing it is your best option – don’t leave it in the fridge! I have found pie crust to get weird if left in the fridge for more than 36 hours. So, you can prep this ahead of time and freeze it if you don’t plan to use it in 24 hours. When removing pie crust from the freezer, just place it in the fridge to thaw for 24 hours before using.

What can I make with Sourdough Pie Crust?

So many things! You can use your favorite fruit pie filling and fill this Sourdough Pie Crust with everything from apple, strawberry, peach, blueberry, blackberry and more. Or you can use it in place of my traditional pie crust in any of the pie recipes on my site! And, it’s also delicious in my Sourdough Apple Pie recipe that uses this crust.

What can I use for a pie wash if I don’t have eggs?

If you don’t have eggs, you can still achieve a golden brown pie crust with many other options! Or even if you have eggs and you don’t want to waste a whole egg on a pie.

My favorite pie wash is a mix of water and honey (1 tablespoon water plus 1 tablespoon of honey. You’ll need to microwave for a few seconds to melt the honey so it can melt into the water, then just brush it on with a pastry brush. This achieves the most perfect golden brown pie crust ever; it is seriously my favorite! It does provide a slight honey flavor to the pie, so if you don’t want that, then opt for something else.

You can also use heavy whipping cream, milk, or melted butter as options as well!

How to Make Pie Crust with Sourdough Discard

Step 1

Measure your flour and sugar into the bowl of a stand mixer. Or if you are not using a mixer, measure into a large bowl. Mix together to combine the flour and sugar.

Step 2

Add the cold water and sourdough discard into a separate bowl. Mix together using a spoon or fork. It helps to incorporate the sourdough discard into the water so you don’t end up with chunks! Something my friend Hannah at Make It Dough taught me!

Step 3

Cut the butter into small cubes. The smaller the cubes, the flakier your crust will be. Just like with traditional butter pie crust. I prefer to cut my butter sticks into at least 4 pieces, in half, and in half again. If I cut wrong and end up with a large piece, I’ll even cut it again! Then cut into cubes from there.

Step 4

Add the cold, cubed butter into the bowl with the flour. If you are using your stand mixer, mix on low with the paddle attachment until the mixture looks like wet sand. If using your hands, you can squish the butter and the flour together with your fingers to combine, until it looks like wet sand. You can also use a pastry cutter, if you have one.

Step 5

Once the mixture looks like wet sand, immediately add in all the water and sourdough discard mixture. If using your mixing, continue mixing on low just until it’s combined, do not over mix. If using your hands, squish the flour into the liquid and continue to do so until a stiff dough forms. Do not knead and do not over mix. As soon as the dough comes together, it’s done.

Step 6

Form the dough into the portions you need for your recipe. If making a traditional double crust (top and bottom), separate dough into disks that weigh about 200 grams and 300 grams. If making 2 galettes, separate into 2 disks that weigh about 250 grams each. If making 5 mini galettes, separate dough into 5 portions that weigh about 100 grams each and form into disks.

Step 7

Wrap the pie dough in plastic wrap tightly and refrigerate for 24 hours. Or, you can freeze it for up to 3 months.

Why organic?

Why use organic ingredients in this recipe? You all know I’m a huge organic advocate, and I bet you may be thinking sometimes, Why would I even bother to use organic ingredients in something that is so sweet and indulgent? But, that is the exact reason why you should use organic ingredients! Sweet things need to have flavor in order to be good, otherwise they are just sweet and they don’t taste like much else. Organic ingredients are more pure than conventional ones, therefore they actually have more flavor than the non organic options. Say it with me, organic means more flavor! And not just more flavor but a more true and pure flavor. And organic ingredients are much healthier for you to eat in general as they do not contain GMOs or anything artificial. Plus, you are being environmentally friendly when you choose organic ingredients!

So, I highly recommend that you buy the best organic ingredients for this recipe! You can also shop my Amazon Storefront for all my favorite organic ingredients here. Tip – hover over each ingredient to see the name. And if you want to learn more about organic foods and the difference, read my post here on Food Labels and What They Mean.
