Red Mill Gluten Free Flour Pie Crust Recipe: Crispy Edges and Zero-Fuss Assembly

This Red Mill gluten-free flour pie crust delivers the crispy edges and sturdy structure you crave without the guesswork. ✨ After years of testing gluten-free crusts that crumbled or sogged, I perfected this foolproof method that works every time—no special tools required.

The secret lies in proper chilling and hydration adjustments that make all the difference.

What sets this recipe apart is its ability to handle both sweet and savory fillings without falling apart. The blend of Red Mill gluten-free flour and xanthan gum creates a texture that mimics traditional crusts, while the cold butter ensures flaky layers.

Unlike many gluten-free recipes, this one doesn't require pre-baking—just assemble, chill, and bake straight with your filling.

By the time it emerges from the oven, you'll have a golden, crispy crust with a tender interior that holds its shape perfectly. The aroma alone will have everyone asking for seconds, and the clean, buttery flavor proves gluten-free doesn't mean sacrificing quality.

This is the crust that finally makes gluten-free desserts feel indulgent again.

Pair it with classic apple pie, rich chocolate cream, or even savory options like chicken pot pie. The same technique works for both single-crust and double-crust pies, making it incredibly versatile. Here's how to make it happen without the frustration.

Ingredients for red mill gluten free flour pie crust

Eight ingredients, two chilling steps—this is your gluten-free crust game-changer.

The Red Mill flour is non-negotiable here—1-to-1 blend is key for that traditional texture. Grab the 26.4 oz bag from King Arthur or Bob's Red Mill; they're the gold standard. The xanthan gum? Measure carefully—too much makes it gummy, too little means it won't hold. If your flour blend already includes it (like some pre-mixed GF flours), skip adding extra. For the butter, cold is critical—cut it into cubes and let it sit in the freezer for 10 minutes before mixing. That's what gets you those flaky layers.

No xanthan gum? Psyllium husk powder at half the amount works in a pinch, but the texture won't be identical. Short on apple cider vinegar? Lemon juice or white vinegar are perfect swaps—the acidity helps tenderize the crust. The egg is non-negotiable for binding, but if you're avoiding it, 1 tbsp ground flaxseed + 3 tbsp water (let sit 5 mins) mimics the effect. For a savory crust, skip the sugar and add 1/4 tsp onion powder instead. And trust me on the cornstarch—it's the secret to that tender bite.

This dough is not your friend if you rush it. After mixing, divide into two discs, wrap tightly in plastic, and chill for at least 2 hours (overnight is best). The longer it rests, the crispier the edges. Once rolled out, don't let it warm up—keep it on a floured tray in the fridge until ready to bake. Leftovers? The dough freezes beautifully for up to 3 months—just thaw in the fridge overnight before using. And if you're making a double-crust pie, use the same dough for both—it's worth the extra effort.

Step-by-step instructions for gluten-free pie crust

Here's how to make a gluten-free crust that rivals traditional dough—crispy edges and all.

In a large bowl, whisk together the 1.5 cups Red Mill Gluten-Free 1-to-1 Baking Flour and the 1 tbsp xanthan gum (this is non-negotiable—it mimics gluten's structure). Sprinkle in the 1 tbsp cornstarch and 1 tbsp granulated sugar, then add the 0.5 tsp Diamond Crystal Kosher Salt. Mix until completely combined—no lumps allowed. This dry blend is your foundation, and getting it right ensures that crispy edge we're after.

I always use a whisk for this step because it distributes the xanthan gum evenly. If you skip this, your crust might end up tough instead of tender. The sugar isn't just for sweetness—it helps with browning, so don't skip it even if you're making a savory pie.

Add the 0.5 cup cold, cubed unsalted butter to the flour mixture. Using a pastry cutter or two forks, work the butter into the flour until you have pea-sized crumbs with some larger butter pieces remaining. This is crucial—you want both texture and moisture, but not a soupy mess. The butter should look like coarse sand with some visible chunks.

Here's the thing—if your butter starts melting too quickly, pop the bowl into the freezer for 5 minutes to firm it up again. The goal is to create those signature flaky layers, and warm butter defeats that purpose. Work quickly but gently; overworking develops gluten-like bonds in the flour.

Create a well in the center of your dry mixture and add the 1 tsp apple cider vinegar, 1 whole cold egg, and 0.25 cup ice water. Using a fork, gently stir until the dough just comes together. Be careful not to overmix—you're aiming for a shaggy, slightly sticky dough that holds when pressed. If it's too dry, add 1 tsp more ice water; if too sticky, sprinkle in 1 tsp more flour.

The vinegar might seem odd, but it helps tenderize the crust by breaking down gluten proteins. Cold egg and ice water prevent the butter from melting prematurely. Wrap the dough in plastic wrap and chill for at least 30 minutes (up to 2 hours works best). This resting period firms up the dough and makes rolling out much easier.

On a lightly floured surface, roll the chilled dough into a 12-inch circle (about ⅛-inch thick). I like to use a rolling pin with guides to maintain even thickness. If the dough cracks, don't panic—just gently press it back together. Transfer the rolled crust to a 9-inch pie dish using a pie dish as a guide to help you center it properly.

Here's where crispy edges happen: Press the dough gently but firmly into the pie dish, letting it drape slightly over the edges. Trim any excess, leaving about ½-inch overhang. Fold the overhang under itself to create a neat edge. Chill the pie dish with the crust for another 15 minutes before filling—this prevents shrinking during baking.

Preheat your oven to 375°F. Line the crust with parchment paper, fill it with dried beans or pie weights, and bake for 15 minutes. Remove the weights and parchment, then prick the bottom all over with a fork. Return to the oven and bake for 5-7 minutes more until the edges are golden brown and the bottom looks dry. This blind-baking step prevents a soggy bottom when you add your filling.

Watch those edges carefully—they should be deep golden brown with just a hint of crispiness. If they brown too quickly, tent with foil to prevent burning. The crust is ready when it's set but still looks slightly underdone in the center—it'll finish cooking when you add your filling. Let it cool for 10 minutes before adding filling to prevent melting.

Troubleshooting this recipe

Cracked Dough Fix

Gluten-free dough cracks easily during rolling, but don’t stress—this is normal! Gently press the cracks back together with your fingers or a rolling pin. If cracks form after transferring to the pie dish, use a fork to tuck them back into place.

For stubborn cracks, sprinkle a little ice water on them before pressing—this helps the dough adhere better. 💡

Soggy Bottom Prevention

The #1 enemy of gluten-free crusts is soggy bottoms. Always blind-bake for 15 minutes with pie weights before adding filling. If your crust still looks undercooked after baking with filling, sprinkle 1 tbsp cornstarch on the bottom before adding the filling.

For extra insurance, pre-bake the crust for 5 minutes after removing the weights. 🍞

Dough Sticks to Surface

Gluten-free dough is trickier to handle than traditional dough, but a lightly floured surface and cold hands are your friends. Use Red Mill gluten-free flour for dusting (it’s lighter than regular flour) and keep your work area chilled.

If the dough still sticks, wet your hands slightly before handling it—this creates a barrier. Never over-flour the dough, or it’ll become tough. ❄️

Edges Shrink During Baking

Shrinking edges happen when the dough isn’t chilled enough. Always chill the dough for at least 2 hours before rolling and 15 minutes after transferring to the pie dish.

If your oven runs hot, reduce temperature to 350°F for baking. For extra stability, press the edges down firmly with your fingers before baking. 🔥

Crust Turns Gray

A grayish crust usually means the butter melted too quickly. Ensure your butter is cold and cubed before mixing, and work quickly. If your dough looks greasy, it’s too warm—pop it back in the fridge for 10 minutes before rolling.

For a brighter color, brush the crust with 1 tbsp melted butter after blind-baking. 🌟

Dough Too Sticky

Sticky dough often means too much ice water or not enough flour. Sprinkle 1 tsp more flour into the mix and knead gently with your hands (just until combined). If it’s still sticky, let it rest in the fridge for 10 minutes to firm up.

Avoid adding too much flour, or the crust will become tough. For extra insurance, wrap the dough in plastic and chill for 30 minutes before rolling. 💪
