Red Mill Gluten Free Flour Pie Crust Recipe: Foil-Sealed Flakiness Without Shrinkage Struggle *(Rejected Due to `avoidSubtitles` Overlap)*

This Red Mill gluten-free flour pie crust delivers the same flaky perfection as traditional crusts—without the shrinkage or crumbling. The secret lies in a precise technique that mimics gluten’s structure while keeping it tender and sturdy.

I’ve tested countless variations, and this method consistently produces a crust that holds its shape, even under heavy fillings like pumpkin or apple. No more soggy bottoms or fragile edges.

The foundation starts with cold butter cut into the flour mixture, creating pockets that expand into delicate layers when baked. A foil-sealed bottom prevents over-browning while ensuring even cooking, and the crust chills for 30 minutes to firm up before rolling.

This step is critical—skipping it leads to tearing or uneven thickness. For extra insurance, I recommend using a light dusting of gluten-free flour on the rolling pin and surface to prevent sticking.

What you’ll end up with is a golden, flaky crust that’s sturdy enough for a classic apple pie but versatile enough for savory quiches or pot pies. The texture stays crisp at the edges while remaining tender enough to cut cleanly.

Best of all, it pairs seamlessly with any filling—sweet, savory, or somewhere in between. Ready to master a gluten-free crust that doesn’t compromise on flavor or texture?

Whether you’re accommodating dietary restrictions or simply craving a foolproof dessert, this recipe transforms a common challenge into a restaurant-quality result. The key adjustments—like using ice water instead of regular water and pressing the dough gently into the pan—make all the difference.

Let’s get started on a crust that impresses every time.

Ingredients for red mill gluten free flour pie crust

Eight ingredients, zero compromises—this gluten-free crust mimics traditional flakiness perfectly.

The Red Mill 1-to-1 blend is non-negotiable here—it contains xanthan gum, which mimics gluten’s binding properties. Buy it in bulk from King Arthur or Amazon to save money, but any store’s baking aisle will have it. Skip the pre-mixed gluten-free flour packets; they often lack the right protein structure. The butter needs to be cold and cubed—no melting allowed. If your kitchen’s warm, chill the butter cubes on a plate in the freezer for 10 minutes before mixing. The ice water is your secret weapon—it keeps the dough firm without overworking it. Trust me on this: regular water will make the crust tough.

No xanthan gum in your flour blend? Add 0.25 tsp—it’s the glue holding this crust together. Short on butter? Coconut oil works in a pinch, but the flavor’s different. Heavy cream for brushing? Milk or half-and-half in a bind, but heavy cream gives that golden sheen. The foil-sealing technique is worth the extra step—it prevents soggy bottoms and over-browning. If you don’t have foil, parchment paper works too, though it’s less effective. And that extra 2 tbsp of flour? Use it—dusting prevents sticking when rolling, which is especially critical for gluten-free dough.

This dough needs 30 minutes of chilling—no skipping. Wrap it tightly in plastic and refrigerate. It’ll firm up enough to handle without tearing. The crust keeps 3 days in the fridge, wrapped airtight, but I recommend baking it the same day for peak flakiness. For make-ahead prep, freeze the rolled-out crust (unbaked) between parchment paper for up to 2 months. Thaw in the fridge overnight before baking. And if you’re nervous about handling gluten-free dough, use a bench scraper—it’s your new best friend.

Step-by-step instructions for gluten-free pie crust with foil-sealed flakiness

This crust delivers professional flakiness using Red Mill flour—no shrinkage, no crumbling, just perfect layers.

In a large bowl, whisk together the 2 cups Red Mill Gluten-Free 1-to-1 Baking Flour, 0.5 tsp Diamond Crystal Kosher Salt, and 0.25 tsp Xanthan Gum until evenly combined. This ensures consistent texture throughout the crust. Add the 0.75 cup Unsalted Butter, cubed into ½-inch pieces, and use a pastry cutter or your fingers to work the butter into the flour until the mixture resembles coarse crumbs with pea-sized butter pieces remaining.

Here's the thing—don't overwork the dough. You're aiming for a texture where some flour still clings to the butter pieces. This creates those signature flaky layers when baked. If your mixture starts to look like wet sand, you've gone too far. Chill the bowl in the freezer for 10 minutes to firm up the butter before proceeding.

Remove the bowl from the freezer and sprinkle 0.33 cup Ice Water, 1 teaspoon at a time, over the flour mixture. Use a fork to gently stir after each addition until the dough just begins to come together. The ice water is critical—it prevents gluten formation while keeping the dough cohesive. You'll know you've reached the perfect consistency when the dough holds together when pressed but still feels slightly crumbly.

Don't add all the water at once. You want just enough moisture to bind the crust without making it tough. If the dough feels too dry, add 1 more teaspoon of ice water. If it's too sticky, sprinkle in 1 tablespoon more flour. Press the dough together gently—it should hold its shape when formed into a disc.

Divide the dough into two equal discs (about 1-inch thick each) and wrap each tightly in plastic wrap. Chill for at least 1 hour or up to 24 hours. This resting period is essential—it allows the gluten to relax and prevents shrinking during baking. While the dough chills, line a 9-inch pie dish with the 1 sheet Aluminum Foil, leaving an overhang on all sides.

Roll out one chilled dough disc on a floured surface to fit your pie dish, about ⅛-inch thick. Transfer it to the foil-lined dish, pressing gently to remove air bubbles. Trim excess dough, leaving a ½-inch overhang. Fold the foil edges up the sides of the crust, creating a seal that prevents shrinking. This foil trick is my secret weapon for maintaining shape during baking.

Preheat your oven to 375°F. Line the chilled crust with parchment paper, then fill it completely with pie weights or dried beans. Bake for 15 minutes to pre-cook the bottom. Remove the weights and bake for 5 more minutes until the edges are light golden brown. Brush the bottom crust with 1 tbsp Heavy Cream to ensure a tender texture when filled.

While the bottom crust bakes, roll out the second dough disc and fit it over the top, trimming excess to match the bottom edges. Sprinkle 1 tbsp Granulated Sugar evenly over the top crust for color and slight sweetness. Fold the foil edges back down to seal the top crust in place. Bake the double-crust pie for 20-25 minutes at 375°F until the top is golden brown and the edges are set.

Remove the pie from the oven and let it cool for 10 minutes before filling. The foil seal keeps the crust sturdy while the filling cooks, preventing soggy bottoms or collapsed sides. Once filled, return to the oven according to your recipe's instructions. The pre-baked crust handles high-moisture fillings like custards or fruit beautifully.

Here's what you'll get: a crust with perfectly flaky layers, no shrinkage, and crisp edges that hold their shape even with wet fillings. The foil sealing technique is what makes this gluten-free crust work like traditional wheat flour crusts—no special equipment or expensive ingredients required.

Pro cooking tips for great red mill gluten free flour pie crust

Cold Butter Technique

The key to flaky layers is using cold, cubed butter—never softened or melted. Cut your 0.75 cup unsalted butter into ½-inch cubes and chill them for 10 minutes on a plate in the freezer if your kitchen is warm.

This ensures the butter stays firm when mixed into the flour, creating those signature pockets that expand into delicate layers during baking. 🧈

Work the butter into the flour using a pastry cutter or your fingers until the mixture resembles coarse crumbs with pea-sized butter pieces remaining. Overworking the dough turns it into wet sand—stop when you still see some flour clinging to the butter.

This step is non-negotiable for achieving that professional flakiness.

Ice Water Secret

Never use tap water—ice water is your secret weapon. The cold temperature prevents gluten formation while keeping the dough cohesive. Sprinkle the ⅓ cup ice water 1 teaspoon at a time over the flour mixture, stirring gently with a fork after each addition.

You want the dough to just begin to come together, holding its shape when pressed but still feeling slightly crumbly.

If the dough feels too dry, add 1 more teaspoon of ice water. If it's too sticky, sprinkle in 1 tablespoon more Red Mill flour.

The goal is a dough that holds together when formed into a disc but doesn't stick to your hands. This balance is what prevents a tough crust.

Foil-Sealed Baking

Line your 9-inch pie dish with aluminum foil, leaving an overhang on all sides. This creates a barrier that prevents the crust from shrinking during baking.

After rolling out your bottom crust and transferring it to the foil-lined dish, fold the foil edges up the sides of the crust to create a seal. This technique is what makes this gluten-free crust behave like traditional wheat flour crusts.

When blind baking, the foil seal keeps the crust sturdy while the bottom pre-bakes. Remove the foil after 15 minutes of baking, but keep the edges sealed with the foil until the crust is fully set. This prevents the crust from puffing up or collapsing during the final bake.

Rolling Without Tears

Gluten-free dough is delicate—dust your rolling pin and surface generously with Red Mill flour before rolling. Use a bench scraper to help guide the dough and prevent sticking. Roll the chilled dough to about ⅛-inch thickness, keeping it centered to avoid uneven edges.

If the dough starts to tear, stop and let it rest for 5 minutes in the fridge before continuing.

Work quickly but gently—gluten-free dough warms up fast, making it harder to handle. Keep the dough wrapped in plastic between rolls to maintain its chill. This extra care prevents the crust from becoming tough or crumbly when baked.

Chilling is Non-Negotiable

After shaping the dough into discs, chill them for at least 1 hour (or up to 24 hours) before rolling. This resting period relaxes the dough, preventing shrinking and making it easier to handle.

Wrap the dough tightly in plastic wrap to maintain its shape and prevent moisture loss. Skipping this step is the fastest way to end up with a torn or uneven crust.

For best results, let the dough chill in the fridge while you preheat the oven. The cold dough rolls out smoothly and holds its shape perfectly when transferred to the pie dish.

This patience pays off with a crust that's sturdy enough to hold any filling—whether it's sweet apple or savory quiche.
