Ingredients for potato flour pie crust
Three core ingredients transform baking forever—no butter, no lard, just pure potato power.
| Ingredient | Amount | Notes |
|---|---|---|
| Potato Flour 🥔 | 1 ½ cups | Gluten-free, finely milled |
| Cold Water 💧 | ½ cup | Chilled for best texture |
| Fine Sea Salt 🧂 | ½ tsp | Diamond Crystal preferred |
| Large Eggs 🥚 | 1 whole | Optional for binding |
| Extra-Virgin Olive Oil 🫒 | 1 tbsp | For brushing crust |
| Raw Sugar 🍚 | 1 tbsp | For sprinkling top |
| Ice Cubes ❄️ | ½ cup | For chilling dough |
Potato flour is the star here, and Bob's Red Mill or Anthony's Goods are my go-tos for the finest gluten-free grind. Look for a vibrant white color—any yellowing means it's past its prime. The flour must be cold when mixed, so chill your bowl and tools beforehand. Freshly milled flour has the best texture, but store-bought works fine if it's been sealed properly. For those with nut allergies, this is a game-changer since it's naturally nut-free. The water needs to be ice cold—room temperature will make the crust gummy.
No eggs? 1 tbsp ground flaxseed mixed with 3 tbsp water works perfectly as a binder. Short on sugar? Turbinado or coconut sugar both work, but raw sugar gives that classic golden finish. The olive oil is non-negotiable for brushing—none of that cheap canola oil. Want extra flakiness? Add 1 tbsp cornstarch to the flour mix. And if you're gluten-sensitive, this crust is your new best friend—it's naturally gluten-free while still delivering that perfect flaky texture.
This dough keeps for 3 days wrapped in plastic in the fridge, but it's best used fresh. For longer storage, wrap tightly and freeze for up to 3 months. The key is to keep everything cold until baking—no warm hands. Once baked, it reheats beautifully in a 350°F oven for 5-10 minutes. I always make extra dough—it's perfect for mini pies or tart shells.

Step-by-step instructions for a shatterproof potato flour pie crust
Here's how to create a delicate, zero-shortening crust that holds its shape perfectly.
Combine Dry Ingredients and Cold Water
In a large mixing bowl, whisk together the 1.5 cups potato flour and 0.5 tsp fine sea salt until evenly distributed. This gluten-free flour needs proper hydration to develop structure, so don't skip this step. Add the 0.5 cup cold water all at once and mix vigorously with a fork or wooden spoon until a thick, shaggy dough forms.
You'll notice the dough is initially sticky and resistant—this is normal with potato flour. The cold water prevents gluten formation while still activating the starches. Mix for about 2 minutes until the dough begins to pull away from the sides of the bowl and forms a cohesive mass. If it's still too wet, add 1 tablespoon more potato flour; if too dry, add 1 teaspoon more water.
Incorporate Egg and Olive Oil for Binding
Make a well in the center of the dough and crack in the 1 whole large egg. Using your hands or a rubber spatula, gently fold the egg into the dough until fully incorporated. The egg provides additional binding and helps create a tender, flaky texture. Add the 1 tablespoon extra-virgin olive oil and continue mixing until the dough becomes smooth and elastic.
At this stage, the dough should be pliable but not sticky. If it's still too wet, knead in 1 additional tablespoon of potato flour; if too dry, add 1 teaspoon more cold water. The goal is a dough that's soft enough to roll out but firm enough to hold its shape. Wrap the dough tightly in plastic wrap and refrigerate for at least 30 minutes—this resting period is crucial for developing texture.
Chill the Dough with Ice Cubes
Place the 0.5 cup ice cubes in a shallow dish and position the wrapped dough on top. This indirect chilling method ensures the dough cools evenly without developing a tough exterior. Refrigerate for another 20-30 minutes until the dough is completely cold and firm to the touch. Cold dough rolls out more easily and prevents shrinking during baking.
While the dough chills, preheat your oven to 375°F. Roll out the dough between two sheets of parchment paper to 1/8-inch thickness—this thinness prevents cracking while still providing structure. Transfer the rolled dough to a 9-inch pie dish, gently pressing it into the corners. Trim any excess dough hanging over the edge.
Blind-Bake for a Perfect Foundation
Line the crust with parchment paper and fill it completely with pie weights or dried beans. Bake for 15 minutes at 375°F until the edges begin to set. Remove the weights and bake for 5-7 additional minutes until the crust is lightly golden. The key here is patience—rushing leads to a soggy bottom.
Brush the baked crust with a thin layer of extra-virgin olive oil and sprinkle evenly with 1 tablespoon raw sugar. This creates a subtle caramelized crust while adding a touch of sweetness. Return to the oven for 2-3 minutes to melt the sugar slightly, then remove and let cool completely before adding your filling.
Final Assembly and Baking
Once your pie filling is prepared, pour it into the cooled crust. The pre-baked foundation prevents a watery bottom while maintaining a delicate texture. Bake according to your filling's requirements, typically at 350°F for 45-60 minutes, until the filling is set and the crust is golden.
This potato flour crust delivers the perfect balance of tenderness and structure—no shortening required. The result is a shatterproof base that holds up to both sweet and savory fillings without becoming tough or greasy. Serve warm with your favorite toppings for an impressive, foolproof crust every time.
Pro Tips For Making Potato Flour Pie Crust
- SIFT THE FLOUR: Potato flour is heavy and clumpy—don’t just dump it in. Sift it through a fine-mesh sieve into your bowl first. I used to skip this, and my crusts turned out dense and uneven. A quick 30-second sift makes all the difference in texture.
- WEIGH THE EGGS: Crack those eggs into a separate bowl first, then measure by weight (about 50g per large egg) instead of volume. Eggs vary wildly in size, and you don’t want a crust that’s either too gummy or too dry. I learned this after making a crust that looked perfect but fell apart when sliced.
- CHILL THE DOUGH: Press the dough into your pie dish, wrap it tightly in plastic, and refrigerate for at least 1 hour—no exceptions. Cold dough prevents shrinking and makes it easier to handle. I once rushed this and ended up with a crust that puckered like a sad accordion.
- BRUSH WITH OIL: Before baking, lightly brush the chilled dough with a tiny bit of extra-virgin olive oil (about 1 teaspoon) using a pastry brush. It adds a subtle richness and helps the crust brown evenly. Sounds simple, but it’s the thing that makes a good crust actually taste great.
Creative variations of this potato flour pie crust
Savory Tart Twist
Transform this crust into a savory tart base perfect for quiches or galettes. Skip the sugar topping and brush the baked crust with a mix of 1 tbsp olive oil and 1 tsp fresh thyme instead.
Fill with a spinach and goat cheese combination or caramelized onions for a restaurant-worthy appetizer. The potato flour adds a subtle earthiness that pairs beautifully with herbed fillings. 🧀
Sweet Potato Swap
For a nutty, caramelized flavor, replace half the potato flour with ¾ cup sweet potato flour. This variation adds depth to fruit pies like apple or cherry, creating a crust with a toasted, almost biscuit-like texture.
Reduce the water by 1 tbsp since sweet potato flour absorbs differently. The result? A crust that holds up to juicy fillings without turning soggy. 🍠
Herb-Infused Crust
Boost flavor by mixing 1 tbsp finely chopped fresh herbs (like rosemary or chives) directly into the dry flour before adding water. For a garlic twist, infuse the olive oil with 2 minced garlic cloves before brushing.
These variations elevate both sweet and savory pies, adding aromatic complexity without overpowering the filling. Perfect for herb crust quiches or rosemary shortbread-style pies. 🌿
Gluten-Free Adaptations
This crust is already gluten-free, but for extra insurance, use certified gluten-free potato flour (like Anthony's Goods). For a nut-free option, ensure no cross-contamination with nuts during storage.
The crust works beautifully in fruit pies (like berry or peach) and savory hand pies—just fold the edges for a rustic finish. It’s a game-changer for gluten-sensitive bakers who crave flaky texture. 🥧
Mini Pie Craze
Roll out the dough to ¼-inch thickness and cut into 3-inch circles using a round cutter. Press into greased mini muffin tins and blind-bake for 8-10 minutes at 375°F.
Fill with mini apple slices or savory mushroom duxelles, then bake until golden. These single-serving pies are perfect for parties—they’re easy to handle and universally loved. 🍏
Freezer-Friendly Shortcuts
Pre-roll the dough and freeze it between parchment paper for up to 1 month. When ready to bake, thaw in the fridge overnight, then blind-bake as directed.
This is my go-to hack for busy days—just pull it from the freezer, pop it in the oven, and let the filling do the work. Ideal for holiday pies or last-minute desserts. ❄️

Frequently asked questions
Why does this potato flour crust turn out shatterproof?
The secret lies in potato flour's unique starch structure. Unlike wheat flour, it develops a delicate lattice network when hydrated properly, creating layers that separate beautifully during baking. The cold water and egg binding prevent toughness while the thin rolling (1/8-inch) ensures even heat distribution. This method mimics traditional flaky crusts without shortening!
Can I make this crust without eggs?
Replace the egg with 1 tbsp ground flaxseed + 3 tbsp water (let sit for 5 minutes to gel). For extra binding, add 1 tsp psyllium husk powder to the dry ingredients. The texture will be slightly denser but still sturdy enough for most fillings. Test with a savory quiche first for best results.
What's the best way to prevent cracks?
Chill the dough thoroughly (1 hour total) and roll it between parchment paper to 1/8-inch thickness. Avoid pressing too hard when transferring to the pie dish—gentle coaxing prevents stress cracks. For extra insurance, prick the bottom with a fork before blind-baking. The ice cube chilling method is key for even cooling.
How do I adapt this for a deep-dish pie?
Double the recipe and use a 9.5-inch springform pan. Roll the dough to 1/4-inch thickness and build up the sides by pressing extra dough into the base before crimping. Blind-bake in stages: 15 minutes with weights, then 10 minutes without before adding filling. The thicker crust needs more time to set without collapsing.
Will this crust work for a frozen pie?
Yes! Pre-bake the crust as directed, then freeze the assembled (unbaked) pie for up to 2 months. Bake straight from frozen at 375°F for 10 minutes, then reduce to 350°F for the remaining time. The potato flour's structure prevents sogginess during thawing. Add 5-10 minutes to baking time for frozen pies.
