Ingredients for red mill gluten free flour pie crust
Nine ingredients, one perfect gluten-free crust—no crumbling, no soggy bottoms, just golden lattice magic.
| Ingredient | Amount | Notes |
|---|---|---|
| Red Mill Gluten-Free 1-to-1 Baking Flour 🌾 | 2 ½ cups | Sifted for even texture |
| Cold Unsalted Butter 🧈 | ¾ cup | Cubed, not melted |
| Ice Water 💧 | ⅓ cup | Very cold, not tap |
| Diamond Crystal Kosher Salt 🧂 | ½ tsp | Fine grain preferred |
| Flaxseed Meal 🌱 | 1 tbsp | For vegan flax egg |
| Cold Water 💧 | 3 tbsp | For flax egg activation |
| Aluminum Foil 📄 | 1 sheet | 12x15 inches for lattice |
| Large Egg 🥚 | 1 whole | Optional for binding |
| Granulated Sugar 🍚 | 1 tbsp | For lattice brushing |
The Red Mill 1-to-1 flour is non-negotiable here—it's the only blend that mimics traditional wheat flour's binding properties. King Arthur and Bob's Red Mill both work, but I've found Red Mill's version holds its shape better after baking. Grab the fine grind if available, as it creates a smoother texture. The butter needs to be cold and cubed—never melted—so it doesn't turn the dough greasy. For the flax egg, use golden flaxseed meal (not whole seeds) and let it sit for 5 minutes to fully thicken before mixing into the dough. Bob's Red Mill sells it in bulk bins if you want to stock up.
No flaxseed meal? Chia seeds work at double the amount (2 tbsp chia + 6 tbsp water). Short on butter? Coconut oil solidified in the fridge works in a pinch, though it adds a slight coconut flavor. The foil lattice technique requires heavy-duty aluminum foil—the cheap stuff tears. For the egg, aquafaba (chickpea brine) at 3 tbsp makes a great vegan substitute if you skip the flax egg entirely. The sugar on the lattice isn't just for looks—it helps create that signature golden color. Confectioners' sugar works too, but granulated gives a slightly glossier finish.
This dough is highly perishable—use it within 24 hours of mixing. Wrap tightly in plastic and refrigerate. For best results, chill the shaped crust for 30 minutes before baking to prevent cracking. Leftover dough can be frozen for up to 3 months, but it loses some of its tenderness when thawed. The lattice pattern requires sharp scissors—dull blades crush the dough. Brush the baked crust with melted butter for extra crispness, but do it immediately after removing from the oven while still warm.
Why You'll Love This Recipe
- No Fuss, No Mess: I swear by this crust because it’s the only gluten-free one that doesn’t turn into a science experiment. Just pulse the Red Mill flour, cold butter, and flaxseed meal in a food processor—no rolling pin, no stress—and you’ve got a dough that behaves like the real deal. (Honestly, my first attempt was a shaky mess, but now it’s my secret weapon.)
- Butter-Laced Crisp: That cold unsalted butter mixed into the Red Mill flour? It’s what makes this crust ridiculously good—flaky, golden edges that crackle like a campfire. The flaxseed meal adds a subtle nuttiness that balances the richness, so it’s never dry or bland. (Yes, even on a Tuesday night.)
- Pie for Any Occasion: This crust works for apple, pumpkin, or even a savory chicken pot pie—no need to switch recipes. I’ve used leftovers to make hand pies for lunchboxes or a quick galette when I’m short on time. Between us, it’s the only gluten-free crust my whole family actually asks for.
- Budget-Friendly Staple: Red Mill flour and butter are pantry basics, and the flaxseed meal stretches the dough further than store-bought mixes. A single batch makes two crusts, so I always have one on hand for emergencies (or dessert cravings). Plus, it’s cheaper than pre-made gluten-free crusts—no excuses not to bake.
Step-by-step instructions for gluten-free pie crust with foil-sealed lattice
Here's how to create a sturdy, golden crust that stays crisp even with juicy fillings.
Mix the Flax Egg and Prepare the Dough
In a small bowl, combine the 1 tablespoon flaxseed meal with the 3 tablespoons cold water. Let it sit for 5 minutes until it thickens into a gel-like consistency—this is your vegan egg substitute. Meanwhile, in a large mixing bowl, whisk together the 2.5 cups sifted Red Mill Gluten-Free 1-to-1 Baking Flour with the 0.5 teaspoon Diamond Crystal Kosher Salt.
Add the 0.75 cup cold cubed unsalted butter to the flour mixture and use a pastry cutter or your fingers to work it into the flour until it resembles coarse crumbs with pea-sized butter pieces remaining. This texture is crucial—it ensures proper flakiness in the final crust. If you're using the optional 1 whole large egg, add it now and mix lightly with a fork until just combined.
Gradually Add Ice Water for Perfect Texture
Begin adding the 0.33 cup ice water, 1 tablespoon at a time, mixing gently with a fork after each addition. The dough will come together when it holds when pressed—it should be slightly shaggy but not sticky. Overmixing develops gluten, which we want to avoid in gluten-free crusts. If the dough feels too dry, add 1 teaspoon more ice water; if too sticky, sprinkle in 1 teaspoon more flour.
Once the dough forms a cohesive mass, turn it out onto a lightly floured surface and gently knead just 4-5 times until smooth. Divide the dough into two equal discs, wrap each in plastic wrap, and refrigerate for at least 1 hour (up to 2 days). Chilling relaxes the gluten-free flour and makes rolling easier.
Roll and Assemble the Crust with Foil Seal
On a lightly floured surface, roll one dough disc into a 12-inch circle, about 1/8-inch thick. Transfer it to a 9-inch pie dish and press gently to fit, letting the edges hang over the rim. Trim the excess dough to 1/2-inch beyond the pie dish edge. Cut a 2-inch circle from the remaining dough for the top crust.
Cut the 1 sheet aluminum foil into a 12x15-inch rectangle. Place the foil over the bottom crust, pressing it gently into the pie dish to create a smooth, even surface. This foil seal prevents the bottom crust from absorbing moisture from wet fillings, ensuring it stays crisp. Brush the foil with a light coating of water to help it adhere.
Create the Lattice Top and Bake to Golden Perfection
Roll out the remaining dough to 1/8-inch thickness. Using a sharp knife or pizza cutter, cut the dough into 1-inch strips. Arrange half the strips horizontally across the foil, spacing them 1/4-inch apart. Brush these strips with the 1 tablespoon granulated sugar dissolved in 1 teaspoon water—this creates that signature golden lattice color.
Fold back every other horizontal strip, then lay the remaining strips vertically across the lattice, again spacing them 1/4-inch apart. Unfold the folded strips to create the classic lattice pattern. Brush the top crust with the remaining sugar mixture. Preheat your oven to 375°F and bake for 20-25 minutes until the crust is deep golden brown and the foil is crisp.
Remove Foil and Finish Baking
Carefully remove the foil from the baked crust using tongs. Return the crust to the oven and bake for an additional 5-8 minutes until the bottom is golden and the foil imprint is no longer visible. Let the crust cool completely before adding your filling—this prevents sogginess and ensures it holds its shape.
The result should be a crisp, flaky crust with a beautiful golden lattice pattern that stays sturdy even with the juiciest pie fillings. The foil seal technique is the secret to maintaining that perfect texture throughout.
Pro Tips For Making Red Mill Gluten Free Flour Pie Crust
- Chill the Butter Properly: Take your unsalted butter straight from the fridge—no thawing—and cut it into ½-inch cubes. If it’s too soft, pop the dough in the freezer for 10 minutes mid-rolling; gluten-free dough hates warmth and will turn gummy faster than regular crust.
- Mix Flaxseed Meal First: Combine the flaxseed meal with ice water before adding it to the dry ingredients—this creates a gel-like binder that mimics gluten’s structure. Stir it for 30 seconds until it thickens slightly; skipping this step means your crust will crumble like stale crackers.
- Press, Don’t Roll: Gluten-free dough tears easily, so skip the rolling pin. Press the dough into the pan with your fingertips, starting from the center and working outward—this keeps it from cracking. A light spray of ice water on your hands prevents sticking (yes, even if you’re impatient like me).
- Blind-Bake with Weights: Use dried beans, rice, or even frozen veggies instead of pie weights for blind-baking—just spread them evenly and bake until golden. This traps heat better than pie weights alone, and you won’t lose any fillings to soggy crust. (Pro move: Sprinkle a little extra flour on the dough before adding weights.)
Troubleshooting your red mill gluten free flour pie crust
Dough Too Dry?
Gluten-free dough often feels dry because the flour absorbs more moisture. If your dough cracks when rolling, add 1 teaspoon ice water at a time until it becomes slightly tacky. I’ve found that Red Mill flour sometimes needs an extra 1-2 teaspoons more water than called for.
Wrap the dough tightly in plastic and chill for 30 minutes to help it relax and bind better. 💧
Crust Cracking?
Cracking happens when gluten-free dough isn’t chilled long enough or is rolled too thin. Let the dough rest in the fridge for at least 1 hour before rolling, and keep it 1/8-inch thick—thinner dough cracks easily.
If cracks appear, brush them with a little ice water and gently press them closed before baking. Pre-baking the crust for 5 minutes before adding filling also helps prevent cracks from filling moisture. 🥧
Soggy Bottom?
The foil seal is your secret weapon against soggy bottoms, but if yours still gets soft, try these fixes: Blind-bake the crust for 10 minutes before adding filling, or sprinkle 1/4 cup crushed cornflakes or gluten-free breadcrumbs on the foil before baking.
For extra insurance, brush the baked crust with 1 tablespoon melted butter after removing it from the oven. 🍞
Lattice Falling Apart?
Weak lattice strips usually mean the dough wasn’t chilled enough or the strips were cut too wide. Roll the dough 1/8-inch thick and cut strips 1 inch wide—any wider, and they’ll sag. Brush the strips with the sugar-water mixture after arranging them on the crust to help them set.
If the lattice still feels flimsy, press it gently into the foil with your fingers before baking. ✂️
Pale or Uneven Color?
Gluten-free crusts often bake unevenly because they lack gluten’s structure. Brush the lattice and the edges of the crust with the sugar-water mixture for even browning. For extra color, broil for 1-2 minutes at the end, watching closely to avoid burning.
If the crust still looks pale, increase oven temp to 400°F for the final 5 minutes of baking. 🌟
Dough Sticking to Surface?
Gluten-free dough is stickier than traditional dough, but a lightly floured surface and proper hydration solve this. Use Red Mill flour for dusting (it’s finer than all-purpose), and avoid over-flouring—just a light coating prevents sticking.
If the dough still clings, wet your hands slightly before handling it. For rolling, I swear by a silicon baking mat—it reduces sticking without extra flour. 🧤

Frequently asked questions
Why does this gluten-free crust need ice water instead of regular water?
Ice water prevents the butter from melting too quickly, which keeps the crust flaky. Cold water also helps the gluten-free flour bind properly without developing gluten. The shock of cold temperature slows down hydration, giving you more control over the dough's texture—especially important since gluten-free flours absorb moisture differently than wheat flour.
Can I make this crust without eggs or flaxseed?
Yes! For the flax egg, try 2 tbsp chia seeds + 6 tbsp water (let sit for 5 minutes). For binding without eggs, mix 1 tbsp cornstarch + 2 tbsp water as a substitute. The crust will be slightly less tender but still hold together well. Just be prepared to handle the dough more gently during assembly.
How do I adapt this for a deep-dish pie?
For deep-dish pies, increase the dough to 3 cups Red Mill flour and divide into 3 discs. Roll one for the bottom, one for the sides (press into a 1-inch high ring), and use the third for the top. Chill each piece separately for 2 hours before assembling. The foil seal technique still works—just cut the foil to match your deep dish shape.
Will this crust work for savory pies like quiche?
This crust handles savory fillings beautifully. For quiche, brush the baked crust with 1 tbsp olive oil after removing the foil to add richness. The lattice design prevents sogginess from cheese sauces, and the crisp texture contrasts perfectly with creamy fillings. Just reduce the sugar in the lattice brush to 1/2 tbsp to avoid sweetness.
How do I store leftover crust?
Wrap baked crust tightly in plastic wrap and store at room temperature for 2 days, or freeze for up to 3 months. For unbaked dough, wrap in plastic and refrigerate for 2 days or freeze for 3 months. Thaw frozen dough in the fridge overnight—never at room temperature—to prevent condensation from making it soggy.
