America's Test Kitchen Gluten-Free Pie Crust Recipe: Cold Butter Layers for Foil-Sealed Shatterproof Crusts

This America's Test Kitchen gluten-free pie crust delivers the same shatterproof perfection as traditional crusts, but without the gluten. The secret lies in cold butter layers and a foil-sealing technique that prevents sogginess—foil-sealed crusts stay crisp even when filled with juicy fruit or creamy custards.

After years of testing, this method finally cracks the code for gluten-free bakers who refuse to compromise on texture.

The foundation starts with a blend of gluten-free flour and xanthan gum, which mimics the structure gluten provides. Cold butter creates flaky layers, while the foil-sealing trick ensures the crust bakes evenly without absorbing moisture from fillings.

Unlike many gluten-free crusts that turn dense or crumbly, this recipe delivers a tender yet sturdy base that holds its shape under any filling—sweet or savory.

What makes this crust truly revolutionary is its versatility. Use it for apple pies, quiches, or even savory tart shells without worrying about a soggy bottom. The foil-sealing method also means you can blind-bake for perfect results every time, whether you're prepping ahead or baking straight from the fridge.

No more fragile crusts that disintegrate at the touch of a fork.

Once you try this foil-sealed, gluten-free masterpiece, you'll never go back to store-bought crusts. The key is patience—letting the dough rest and baking it just until golden ensures that shatterproof finish. Ready to elevate your gluten-free baking? Here’s how to make it.

Ingredients for america's test kitchen gluten free pie crust

Nine ingredients, zero compromise. This gluten-free crust delivers shatterproof perfection with cold butter and foil-sealing magic.

The gluten-free flour blend is everything here—Bob's Red Mill 1:1 or King Arthur Measure for Measure are the gold standards, but any reputable brand with xanthan gum included works. Avoid blends without xanthan—that's what gives the structure. For butter, Plugrá is my go-to (it stays cold longer), but any unsalted brand works if you keep it chilled. The key is cold butter cubes—don't let them warm up, or you'll lose that flaky magic. If your blend doesn't include xanthan gum, add the extra 0.5 tsp—it's non-negotiable for that tender yet sturdy texture. And for the love of pie, use ice water—room temp water makes the dough gummy.

No gluten-free flour? Substitute a 1:1 blend of rice flour and tapioca starch—it's what ATK tested originally. Running short on butter? Coconut oil works in a pinch (use same amount), but the flavor won't be identical. The foil-sealing trick requires heavy-duty foil—the cheap stuff tears. For pie weights, dried beans in a thin layer work perfectly (just save them for next time). The cornstarch is optional but worth it if you're prepping ahead—dusting the foil prevents sticking. And if you're making a savory tart, skip the sugar—the crust's natural flavor shines without it.

This dough must rest for at least 30 minutes—patience pays off with better layers. Store unused dough between parchment in the fridge for up to 3 days or freeze for 3 months. The foil-sealed crust keeps its crispness for 2 days at room temp if stored in an airtight container. For blind baking, preheat your oven to 375°F—this crust bakes faster than you'd expect. And here's the pro move: brush the baked crust with cold heavy cream before adding filling—it creates that golden, glossy finish you see in bakery pies.

Step-by-step instructions for america's test kitchen gluten-free pie crust

This foolproof method delivers a shatterproof gluten-free crust with cold butter layers and foil-sealing.

In a large bowl, whisk together the 2.5 cups gluten-free all-purpose flour blend, 0.5 tsp xanthan gum, 0.5 tsp diamond crystal kosher salt, and 1 tbsp granulated sugar. This blend already contains the xanthan gum, so no additional measuring is needed—just combine everything evenly. The sugar balances the buttery richness while helping create a tender texture.

Add the 1 cup unsalted butter, cut into ½-inch cubes (keep it cold—this is critical). Using a pastry cutter or two forks, work the butter into the flour mixture until you reach pea-sized crumbs with some flour still visible. Overworking will develop gluten, so aim for 20-25 strokes—just enough to coat the butter pieces. The dough should resemble coarse sand with butter chunks scattered throughout. If it feels too dry, add 1-2 teaspoons of ice water from the 0.5 cup total to help bind it without over-moistening.

Add the 0.5 cup ice water all at once and gently mix with a fork until the dough just comes together. It should hold when pressed but still feel slightly crumbly—this is perfect for gluten-free dough. Avoid overmixing, which can make the crust tough. If the dough feels too sticky, sprinkle in 1-2 tablespoons of additional flour from the blend.

Turn the dough onto a lightly floured surface and gently press it into a 6-inch disk (about ½-inch thick). Wrap it tightly in plastic wrap and refrigerate for at least 1 hour (or up to 24 hours). Chilling firms up the butter layers, ensuring they stay intact during rolling and baking. This step is non-negotiable—skipping it will result in a greasy, fragile crust.

Remove the dough from the fridge and let it sit at room temperature for 5 minutes to soften slightly. On a lightly floured surface, roll the dough into a 12-inch circle, about ⅛-inch thick. I use a rolling pin with a 12-inch guide to ensure even thickness. If the dough resists, let it rest another 5 minutes—gluten-free dough can be stubborn.

Carefully transfer the rolled dough to a 9-inch pie dish, trimming any excess dough hanging over the edges. Gently press the dough into the dish, ensuring it adheres to the bottom and sides. The edges should be ½-inch thick—this prevents shrinking during baking. Fold the overhang inward and crimp the edges with your fingers or a fork. Place the pie dish on a baking sheet lined with parchment paper to catch any filling spills.

Preheat the oven to 375°F. Line the crust with the 1 sheet aluminum foil, pressing it into the bottom and sides. Fill the center with 1 cup pie weights or dried beans (these prevent puffing). Bake for 15 minutes, then remove the weights and foil. Prick the bottom all over with a fork to prevent air pockets, then return to the oven for another 10-12 minutes until the crust is golden brown and dry to the touch.

For extra insurance, brush the hot crust with 2 tbsp heavy cream mixed with a pinch of salt. This creates a glossy finish and adds richness. If the edges aren’t fully set, tent with foil and bake 5 more minutes. The crust should hold its shape when tapped—no soggy bottoms here! Let it cool completely before filling to prevent melting.

Once the crust is fully cooled, dust the interior lightly with 1 tbsp cornstarch (sifted) for a crispier texture when filled. This step is optional but recommended for fillings like custards or fruits that release moisture. The cornstarch acts as a barrier, keeping the crust from absorbing excess liquid. For a double-crust pie, repeat the rolling and blind-baking process with the top crust, then assemble and bake as directed.

Your gluten-free crust is now ready for any filling—whether it’s a classic pumpkin pie, a tangy lemon meringue, or a rustic berry galette. The secret lies in the cold butter layers and precise baking technique, ensuring a shatterproof base every time.

Pro cooking tips for america's test kitchen gluten free pie crust

Cold Butter Magic

This crust’s secret weapon is cold butter—never softened or melted. Cut 1 cup unsalted butter into ½-inch cubes and keep them chilled until they’re pea-sized in your dough. I use Plugrá butter because it stays cold longer, but any brand works if you’re precise.

The butter should remain firm to the touch when you handle it—if it softens, pop it back in the fridge for 10 minutes. Cold butter creates those perfect flaky layers that make gluten-free crusts shine. 🧈

Foil-Sealing Trick

Line your unbaked crust with heavy-duty aluminum foil before blind baking—this prevents sogginess and ensures even cooking. Press the foil into the bottom and sides, then fill with 1 cup pie weights or dried beans. Bake at 375°F for 15 minutes, then remove the foil and weights.

The foil acts as a barrier, keeping moisture out while the crust sets. For extra insurance, prick the bottom with a fork before finishing the bake. This method works like a charm for both sweet and savory pies. 📄

Resting is Non-Negotiable

Let your dough rest for at least 1 hour in the fridge—this firms up the butter layers so they don’t melt during rolling. I often rest mine overnight for even better results.

Gluten-free dough can be stubborn, so if it resists rolling, let it sit another 5 minutes at room temp. The goal is a smooth, even ⅛-inch thickness—any thicker, and it won’t bake evenly. Patience here pays off with a crisp, sturdy crust. ⏰

Edge Crimping Secrets

For a professional finish, crimp the edges with your fingers or a fork before baking. Press the dough edges inward at a 45-degree angle to create a decorative rim. If the dough shrinks during baking, wet your fingers slightly and press the edges back into place.

For extra flair, use a pie crust fork or the tines of a fork to create a classic lattice pattern. This step isn’t just for looks—it also helps seal in moisture. 🍰

Heavy Cream Brush

After blind baking, brush the hot crust with 2 tbsp heavy cream mixed with a pinch of salt. This creates a glossy, golden finish and adds richness. The cream also helps set the crust edges, preventing them from softening when you add filling.

For a double-crust pie, brush the top crust too—it’ll look like it came from a bakery. This is my favorite pro trick for restaurant-quality results. ✨

Cornstarch Barrier

For fillings like custards or juicy fruits, dust the cooled crust with 1 tbsp cornstarch before adding filling. This creates a barrier that keeps the crust crisp instead of soggy. Sift the cornstarch lightly over the interior—don’t press it in.

It’s especially useful for pies with high moisture content, like berry or pumpkin fillings. Trust me, this small step makes a huge difference. 🌽
