All Butter Pie Crust Recipe: America's Test Kitchen's Foil-Sealed Secret to Shatterproof Layers

America's Test Kitchen's all butter pie crust recipe delivers the shatterproof layers that make every slice a showstopper. 💛 The secret lies in cold butter, minimal handling, and a foil-sealing technique that prevents soggy bottoms—no more flimsy crusts that crumble at the first forkful.

This isn't just a crust; it's the foundation for perfect pies, tarts, or hand pies that hold their shape even when loaded with filling.

The method emphasizes precision: chilled butter cut into flour, shaped into discs, and baked with a protective foil barrier. What sets this apart is the foil-sealed secret—a technique that ensures even baking while preventing moisture from seeping in.

The result? A crust with a crisp, golden exterior and a tender interior that stays sturdy under any filling, whether it's custard, fruit, or creamy cheese.

Ready in just 30 minutes of prep plus 20 minutes of baking, this crust requires no fancy equipment—just patience and a food processor. The cold butter creates flaky layers that unfold beautifully when sliced, while the foil-sealing method guarantees a foolproof bottom that won't turn soggy.

This is the crust that professional bakers swear by, and now you can achieve it at home.

Use it for classic apple pie, savory galettes, or mini hand pies—this versatile crust adapts to any recipe while maintaining its signature structure. Store leftovers in the fridge for up to 5 days or freeze for months. Let's get started on the perfect foundation for your desserts.

Cold butter, precise measurements, and a foil-sealed secret create America's Test Kitchen's legendary shatterproof crust.

The unsalted butter is non-negotiable—it must be cold and cubed (not softened) to create those signature flaky layers. Whole Foods or Trader Joe's carry high-quality European-style butter that melts beautifully. Avoid salted butter unless you adjust the salt later. For flour, King Arthur or Bob's Red Mill brands are ideal—they're finely milled and consistent. The sugar here isn't for sweetness but to help the flour absorb moisture. If you're using a food processor, pulse the butter and flour until it resembles coarse crumbs—over-processing is the enemy of flakiness.

No heavy cream? Skip it—the crust will still be perfect, but it adds a luxurious richness that pairs well with fruit fillings. Running out of ice water? Freeze 1 tablespoon at a time in a small container—it'll be ready when you need it. For salt, Diamond Crystal dissolves more easily than Morton's, so use that if you have it. The foil is critical—use heavy-duty foil and press it firmly against the crust edges to prevent any moisture from seeping in during baking. If you're nervous about handling, chill the dough for 15 minutes before rolling it out.

The dough keeps best when wrapped tightly in plastic and stored in the fridge for up to 48 hours. For longer storage, freeze the discs (before baking) for up to 3 months—just thaw overnight in the fridge before baking. Once baked, store cooled crusts in an airtight container for 5 days. To reheat, cover with foil and warm at 350°F for 5-10 minutes. The foil-sealed technique ensures the bottom stays crisp and dry, so don't skip it—this is what makes the crust truly foolproof.

Master this technique and you'll achieve a shatterproof crust with perfect flakiness every time.

Place the 1 cup unsalted butter in a freezer-safe container and cut it into ½-inch cubes using a sharp chef's knife. The butter must be completely cold—this creates the flaky layers. I press the cubes between two sheets of parchment paper with a rolling pin for 5 minutes to ensure they're uniformly firm. If any pieces feel soft, return them to the freezer for 10 minutes before proceeding.

This chilling step is non-negotiable. Warm butter releases too much fat during mixing, resulting in a tough crust rather than the delicate layers we're after. The cubes should feel solid to the touch but not rock-hard—think of them like frozen butter cubes you'd use for baking.

In a large mixing bowl, whisk together the 2.5 cups all-purpose flour, 0.5 tsp Diamond Crystal kosher salt, and 1 tbsp granulated sugar until evenly distributed. Add the cold butter cubes and use a pastry cutter or your fingers to work the butter into the flour until you have pea-sized crumbs with some larger butter pieces remaining. This is called the "reverse cream" method and it's key to flaky texture.

Don't overwork the mixture—just until the butter is mostly coated with flour. You should still see some larger butter pieces. If the dough starts to stick together, chill it for 5 minutes before proceeding. The goal is to maintain cold butter throughout the process, which prevents the gluten from developing too much and keeps those beautiful flaky layers intact.

Add the 0.25 cup ice water and 1 tbsp heavy cream (if using) to the mixture and gently stir with a fork until the dough just comes together. The ice water is crucial—it's cold enough to keep the butter solid while providing just enough moisture to bind the dough. If the mixture feels too dry, add 1 teaspoon ice water at a time until it holds together when pressed.

Turn the dough out onto a lightly floured surface and divide it into two equal discs. Wrap each disc tightly in plastic wrap and refrigerate for at least 1 hour (up to 2 days). This resting period relaxes the gluten and allows the flour to fully hydrate, resulting in a more tender crust. The dough should feel cold and firm when you remove it from the refrigerator.

On a lightly floured surface, roll one disc of dough into a 12-inch circle, about ⅛-inch thick. The key here is to keep the dough cold—if it starts to warm up, return it to the refrigerator for 10 minutes before continuing. Line a 9-inch pie dish with the rolled dough, pressing gently to shape it to the bottom and sides. Trim any excess dough hanging over the edge.

This is where the foil technique comes into play. Place the pie dish on a sheet of aluminum foil and fold the foil up around the sides of the crust. This creates a barrier that prevents the crust from puffing up during baking, which would make it difficult to remove from the dish later. The foil also helps maintain even heat distribution for perfect browning.

Preheat your oven to 375°F. Place a second sheet of aluminum foil over the crust and fill it with dried beans or pie weights (about 2 cups). Bake for 15 minutes to pre-bake the bottom crust. Remove the weights and foil, then prick the bottom all over with a fork to prevent bubbling. Return to the oven and bake for another 10-15 minutes until the edges are golden brown and the bottom is lightly browned.

Here's the secret: the foil-sealed method ensures the crust bakes evenly without puffing up. The pre-baked bottom prevents sogginess when you add your filling later. For extra insurance, I like to brush the baked crust with a light coating of egg wash (1 egg yolk beaten with 1 tablespoon water) before adding the filling. This creates a beautiful golden finish and adds a subtle sheen to the final pie.
