Ingredients for potato flour pie crust
Five simple ingredients transform into a lattice crust that stays crisp all night long.
| Ingredient | Amount | Notes |
|---|---|---|
| Potato Flour 🥔 | 1 ½ cups | High-quality, fine-textured preferred |
| Unsalted Butter 🧈 | 1 cup | Cold, cubed, high-fat content |
| Ice Water 💧 | ½ cup | Chilled for optimal dough structure |
| Diamond Crystal Kosher Salt 🧂 | ½ tsp | Fine grain for even distribution |
| Granulated Sugar 🍚 | 1 tbsp | Enhances browning and flavor |
The potato flour is the star here—Bob's Red Mill or King Arthur brands deliver the finest texture. For butter, Plugrá or Land O'Lakes unsalted work best, but any high-fat content butter will do. Keep everything cold in the fridge until ready to use; this ensures clean layers. The sugar isn't just for sweetness—it helps create that perfect golden-brown crust. If you can't find potato flour, instant mashed potato flakes work in a pinch, but texture may differ slightly.
No potato flour? Substitute with 1 cup all-purpose flour plus 1/4 cup cornstarch—this mimics the moisture absorption. For butter alternatives, coconut oil solidified in the fridge works but lacks flavor depth. The ice water must be cold—room temperature water will melt the butter prematurely. If your kitchen is humid, reduce water by 1 tablespoon. For a sweeter crust, increase sugar to 2 tablespoons, but keep in mind this will affect browning time.
Wrap the dough tightly in plastic wrap and refrigerate for at least 2 hours before rolling. It keeps in the fridge for up to 48 hours, but for best results, use within 24 hours. For longer storage, freeze the dough between parchment paper for up to 3 months. Thaw slowly in the fridge before using. The crust reheats beautifully—just bake at 375°F (190°C) for 10-12 minutes to restore crispness.

Step-by-step instructions for potato flour pie crust
Master this delicate dough technique for a lattice crust that stays crisp through every bite.
Cut and Chill the Butter
Cut the 1 cup Unsalted Butter into ¼-inch cubes and place them on a plate. Freeze for 15 minutes to firm up completely. This step is critical—cold butter creates flaky layers by resisting the dough's heat during baking. If your kitchen is warm, chill the butter for an extra 5 minutes to ensure it remains firm.
While the butter chills, measure out the 1.5 cups Potato Flour into a medium bowl. The fine texture of potato flour is essential here—it creates a tender yet sturdy crust that won't crumble. Sift the flour lightly to aerate it, which helps incorporate air during mixing and promotes an even, delicate crumb structure.
Mix Dry Ingredients and Incorporate Butter
In the bowl with the potato flour, whisk in the 0.5 tsp Diamond Crystal Kosher Salt and 1 tbsp Granulated Sugar. The salt enhances flavor while the sugar promotes browning and adds subtle sweetness. Mix just until combined—overmixing develops gluten, which can make the crust tough instead of flaky.
Add the chilled butter cubes to the flour mixture. Using your fingertips or a pastry cutter, work the butter into the flour until the mixture resembles coarse crumbs with some pea-sized butter pieces remaining. This texture is ideal—it ensures maximum layering during baking. If the mixture feels too dry, add 1 tablespoon of ice water at a time until it just begins to hold together when pressed.
Hydrate with Ice Water
Gradually add the 0.5 cup Ice Water, 1 tablespoon at a time, using a fork to gently toss the mixture. Ice water is crucial—it keeps the dough cold longer, preventing the butter from melting too quickly and losing its flaky potential. Mix just until the dough comes together when pressed; it should be slightly shaggy and not fully cohesive.
Once the dough forms a rough mass, turn it out onto a lightly floured surface. Gently knead it 4-5 times just to bring it together—no more. Overworking the dough develops gluten, which can make the crust tough. Wrap the dough tightly in plastic wrap and refrigerate for at least 1 hour or up to 2 days. This resting period allows the gluten to relax and the butter to firm up, resulting in a more tender, flaky crust.
Roll and Assemble the Crust
Remove the dough from the refrigerator and let it sit at room temperature for 5-10 minutes to soften slightly. On a lightly floured surface, roll the dough into a ¼-inch thick circle about 12 inches in diameter. The dough should be cold but pliable—if it cracks, let it rest for another 5 minutes before rolling.
Transfer the dough to your pie dish, gently pressing it into the bottom and up the sides. Trim any excess dough hanging over the edge. For a lattice top, roll out the remaining dough into a ⅛-inch thick rectangle about 12x18 inches. Cut ½-inch strips lengthwise, then make ¼-inch cuts every 1 inch along the width of the strips. Unfold the strips and arrange them in a lattice pattern over the pie filling, alternating directions for a classic design.
Blind-Bake for Perfect Crispness
Preheat your oven to 375°F. Line the lattice crust with parchment paper, then fill it with pie weights or dried beans to prevent puffing. Bake for 15 minutes, then remove the weights and bake for an additional 10-12 minutes until the crust is golden brown and fully set. If the edges brown too quickly, cover them loosely with aluminum foil.
For a deeply crisp lattice, brush the baked crust with a light coating of egg wash (1 egg beaten with 1 tablespoon water) before adding your filling. This step ensures a shiny, golden finish and prevents the lattice from becoming soggy. Bake the filled pie according to your recipe's instructions, but keep an eye on the crust—it should remain crisp and golden, not soggy or pale.
Pro Tips For Making Potato Flour Pie Crust
- Use Cold Butter Cubes: Cut your unsalted butter into ½-inch cubes and freeze them for 10 minutes before mixing—this prevents the dough from turning greasy and ensures a flaky texture when baked. I learned this the hard way after dealing with a sad, soggy crust that looked more like a butter blob than a pie shell.
- Mix Just Until Combined: Stop stirring the moment the dough clumps together—overmixing develops gluten and makes the crust tough. Potato flour dough is delicate; handle it like you’re folding a blanket, not kneading bread dough.
- Chill the Dough Twice: Give the dough a 30-minute rest in the fridge before rolling it out, then another 15 minutes after shaping. This prevents shrinking and cracking during baking, especially if your kitchen’s warm like mine usually is.
- Skip the Sugar If Needed: If your crust tastes too sweet, cut the granulated sugar in half—potato flour already adds natural starch sweetness. I was skeptical until I tried it; the crust still holds its shape without tasting like a dessert.
Perfect pairings for this recipe
Sweet Fillings
This potato flour crust shines with classic apple pie—try a spiced filling of 4 cups peeled, thinly sliced Granny Smith apples, ½ cup brown sugar, 2 tbsp lemon juice, and 1 tsp cinnamon.
The crust’s delicate texture contrasts beautifully with the apples’ tartness. For a modern twist, pair it with pumpkin pie filling—the crust’s crispness balances the custard’s creaminess perfectly. 🍏
Savory Options
Don’t limit this crust to desserts! A savory pot pie with shredded chicken, carrots, peas, and a creamy white wine gravy turns it into a hearty vegetarian-friendly main.
For a lighter option, try a spinach and ricotta pie—the crust’s flakiness pairs wonderfully with the rich filling. The lattice design adds elegance to any savory dish.
Beverage Pairings
For sweet pies, a chilled glass of sparkling apple cider (like Martinelli’s) complements the flavors beautifully. For savory pies, a dry Riesling or crisp Sauvignon Blanc cuts through the richness.
If you prefer beer, a Belgian witbier (like Hoegaarden) adds a refreshing citrus note that pairs surprisingly well with both sweet and savory fillings. 🍷
Garnish Ideas
Before serving, brush the lattice with a light egg wash and sprinkle with coarse sugar for extra crunch. For sweet pies, add a dusting of powdered sugar or a drizzle of honey.
For savory pies, a sprinkle of fresh herbs (like thyme or parsley) adds a bright finish. A few toasted pecans or walnuts on top add texture and visual appeal.
Make-Ahead Tips
Assemble your pie up to 24 hours ahead and refrigerate. For best results, bake it 1 hour before serving to ensure the crust stays crisp. If freezing, bake the pie completely, then cool and store in an airtight container for up to 3 months.
Reheat in a 350°F (175°C) oven for 15-20 minutes to restore crispness. 💫

Frequently asked questions
Why does this potato flour crust stay crisp longer than regular flour crusts?
Potato flour absorbs less moisture than all-purpose flour, creating a drier, more stable structure that resists sogginess. The starch content also helps maintain crispness even after baking for extended periods. Plus, the fine texture promotes even layering, so the crust doesn't soften when exposed to fillings.
Can I make this crust without a food processor?
Use your fingertips or a pastry cutter to work the cold butter into the potato flour until you get pea-sized pieces. The key is keeping everything cold and working quickly—this method creates just as many flaky layers as a food processor would. Just be gentle to avoid melting the butter prematurely.
What's the best way to prevent the lattice from getting soggy?
Always blind-bake the crust for 15-20 minutes before adding filling. Brush the baked lattice with egg wash (1 egg + 1 tbsp water) to create a moisture barrier. For extra insurance, sprinkle 1 tbsp granulated sugar on top before baking—it helps absorb any filling moisture while adding sweetness.
How do I fix a cracked lattice while assembling?
Gently press the cracks back together with your fingers or use a small piece of dough to patch them. For a seamless look, brush the edges with a little water and press them flat. If cracks appear after baking, they're usually just cosmetic—simply brush with melted butter and sprinkle with coarse sugar for a pretty finish.
Can I use this crust for deep-dish pies?
This recipe works best for standard or lattice-topped pies, but you can adapt it for deep-dish by increasing the dough quantity by 30%. Roll out two 12-inch circles instead of one, then layer them in your deep dish pan. The potato flour's structure helps prevent shrinking, but you may need to bake it longer to ensure full crispness in the center.
