America's Test Kitchen Pie Crust Recipe: Cold Butter Layers That Stay Perfectly Flaky

The America's Test Kitchen pie crust recipe delivers the flakiest, most reliable foundation for any pie—whether you're baking classic apple or modern key lime. After testing countless variations, I've refined this method to guarantee layers that stay crisp and tender, not tough or greasy.

The secret lies in precise fat distribution and proper chilling, both of which we'll cover step by step.

This recipe uses cold butter cut into flour, creating thin, even layers that melt during baking for maximum flakiness. Unlike shortcut crusts, this version requires just 20 minutes of active prep time followed by essential chilling—no advanced techniques, just proven science.

The result is a crust that holds its shape, resists shrinking, and creates that signature lattice pattern when cut.

Perfect for both traditional pies and free-form tarts, this crust handles fillings from juicy berries to creamy custards without becoming soggy. The key is maintaining proper fat-to-flour ratios and avoiding overworking the dough. Once you master this method, you'll never go back to store-bought crusts—it's that good.

Ingredients for america's test kitchen pie crust

Six simple ingredients transform into the flakiest crust you'll ever bake.

The butter is non-negotiable—use unsalted and let it chill until rock-hard (about 30 minutes). Plugrá or Land O'Lakes work best for consistent results. Cut it into uniform 1/2-inch cubes—they'll distribute evenly in the flour. For the flour, King Arthur or Bob's Red Mill are my go-tos; they're finely milled and consistent. The sugar and vinegar might seem odd, but they're what keep the crust tender and prevent shrinking. Pro tip: use a kitchen scale for the flour if you can—125 grams is more accurate than scooping.

No unsalted butter? European-style butter like President works in a pinch, but add a pinch of salt to compensate. Short on vinegar? Lemon juice at half the amount works too. For the egg yolk, if you're out, 1 tbsp milk or water plus 1/2 tsp baking powder mimics the binding effect. The cornmeal is optional but helps prevent sticking when rolling. If you're making a double crust, double everything—including the chilling time. And trust me, don't skip the chilling. Rushing this step is what makes crusts tough.

This dough keeps for 3 days wrapped tightly in plastic in the fridge, or 6 months frozen between parchment paper. For best results, let it sit at room temp for 10 minutes before rolling. The crust can be pre-baked for 15 minutes at 375°F if you're prepping ahead. Once baked, it reheats beautifully—just pop it in the oven for 5-10 minutes at 350°F. I always make extra dough and freeze half for next time. It's the ultimate make-ahead hack.

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

Here's how to create a flaky, golden crust with layers that stay perfectly crisp.

In a large bowl, whisk together the 3 cups all-purpose flour, 0.5 teaspoon diamond crystal kosher salt, and 1 tablespoon granulated sugar. I like to sift the flour first for a lighter, more even texture—this prevents dense spots in your crust. Use a whisk to break up any flour lumps completely; you want everything uniformly distributed before adding the butter.

Here's the thing—don't skip the sugar. It tenderizes the gluten slightly, which helps create that delicate, flaky texture we're after. The salt isn't just for flavor; it also strengthens the gluten structure just enough to hold those butter layers without tearing when you roll it out.

Add the 1 cup unsalted butter, cut into ½-inch pieces, 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 some butter to stay in larger chunks so it melts during baking and creates steam pockets for flakiness.

I press down gently on the butter pieces during the first minute—this prevents them from curling and ensures even contact with the flour. The mixture should look like coarse sand with some visible butter pieces. If it starts to look like wet sand, you've overworked it, which develops gluten and makes the crust tough. We want that butter to stay cold and distinct.

In a small bowl, whisk together the 1 whole large egg yolk, 1 teaspoon white vinegar, and ¼ cup ice water. The vinegar helps stabilize the egg yolk and creates a more cohesive dough. Add this mixture to the flour-butter combination and gently stir with a fork until the dough just comes together.

Don't overmix here—just until the dough forms when pressed. You'll still see dry spots, but that's normal. The dough should be slightly shaggy and not hold together when pressed into a ball. This prevents the crust from becoming tough. If it's too dry, add 1 teaspoon ice water at a time until it just holds together.

Turn the dough onto a lightly floured surface and gently press it into a 6-inch circle. Wrap it tightly in plastic wrap and refrigerate for at least 1 hour, or up to 2 days. Chilling is non-negotiable—it firms up the butter so it doesn't melt during rolling and prevents the crust from shrinking when it bakes.

I like to place the wrapped dough on a baking sheet before refrigerating. This makes it easier to transfer later without unraveling the wrap. The dough should be cold and firm to the touch when ready to roll. If you're in a hurry, you can freeze it for 20 minutes, but chilling in the fridge gives better results.

Lightly dust a clean surface with ¼ cup yellow cornmeal and roll the chilled dough into a 12-inch circle, about ⅛-inch thick. I use the cornmeal instead of flour because it gives the crust a slightly crispier texture. Roll from the center outward, rotating the dough as you go to maintain even thickness.

Gently transfer the rolled crust to a parchment-lined baking sheet. If you're making a double crust, repeat the process for the top crust. For a single crust, you can use the rolled dough immediately or refrigerate it again for 15 minutes before filling. The key is to keep everything cold—this ensures those beautiful flaky layers develop during baking.

Essential equipment for great america's test kitchen pie crust

Must-Have Tools

Start with a pastry cutter or two forks for cutting butter into flour—this is non-negotiable for even distribution. I use a KitchenAid pastry blender for precision, but a sturdy fork works just as well.

A rolling pin with a smooth surface (I prefer OXO Good Grips) prevents sticking, and a pie dish with a removable bottom makes transferring easier. For measuring, a kitchen scale ensures accurate flour weight—King Arthur's 8-inch scale is my go-to. 🌾

Cold Storage Essentials

Chilling the dough requires proper containers. I wrap dough in plastic wrap and place it in a glass pie dish or ceramic bowl to maintain shape. For longer storage, use airtight containers like Rubbermaid Brilliance—they prevent freezer burn.

A baking sheet helps stabilize dough during chilling, and parchment paper prevents sticking when rolling. Keep a thermometer handy to monitor fridge temp (ideally 40°F or below). ❄️

Rolling and Baking Gear

For rolling, yellow cornmeal (not flour) creates crispier crusts—I use Bob's Red Mill brand. A 12-inch pizza peel helps transfer rolled dough without tearing. For baking, a light-colored metal pie dish (like Wilton's Perfect Results) ensures even browning.

A laser thermometer (I recommend Thermoworks ThermaPen) monitors internal temp—350°F is ideal for pre-baking. For double crusts, a pastry brush applies egg wash evenly. 🔥

Pro Upgrades

Invest in a food processor (like KitchenAid FP14MX) for mixing dough—it's faster and more consistent than hand methods. A pie crust weight (or dried beans) prevents soggy bottoms during pre-baking. For lattice crusts, a sharp chef's knife and ruler create clean cuts.

A cooling rack prevents soggy crusts after baking. For extra flakiness, try European-style butter like Plugrá—it has higher fat content. 💡
