All Butter Pie Crust Recipe: America's Test Kitchen's Foil-Sealed Golden Secret

America's Test Kitchen's all butter pie crust delivers foil-sealed perfection—crisp, flaky layers with golden edges that hold their shape under any filling. 💛 The secret lies in precise technique: cold butter cut into flour, minimal handling, and a foil-sealed bake that prevents over-browning.

I've perfected this method after years of testing, and it's the crust that makes even the simplest pie taste like a bakery masterpiece.

What sets this recipe apart is the foil-sealed edge trick—a technique that ensures even baking while protecting delicate crusts from burning. We use all butter (no shortening) for maximum flavor, and the dough rests overnight for improved texture.

This isn't just a crust; it's the foundation for pies that look and taste restaurant-quality, whether you're making classic apple or modern chocolate cream.

The result is a crisp, tender crust with layers so delicate they practically melt in your mouth. The foil-sealed edges stay golden and sturdy, while the interior remains flaky and buttery.

This method eliminates guesswork—no more soggy bottoms or uneven baking. It's the kind of crust that transforms ordinary desserts into showstoppers.

Ingredients for all butter pie crust recipe america's test kitchen

Precision-cut butter and cold flour create this legendary all-butter pie crust with foolproof foil-sealed edges.

The flour must be unbleached and sifted—King Arthur or Gold Medal brands are ideal for their consistent protein content. Butter quality is non-negotiable: use Plugrá or Land O'Lakes cultured butter for superior flavor and fat content. The cold butter must be cubed into uniform 1/2-inch pieces—no melting! For the kosher salt, Diamond Crystal measures differently than Morton; use the flat-top method for accuracy. Ice water is critical—never room temperature. I always keep a bowl of ice cubes on hand for quick chilling.

No heavy cream? Whole milk with 1 tbsp melted butter works in a pinch, though texture will differ slightly. Salt substitutes? Use 1/4 tsp salt-free seasoning plus 1/4 tsp sugar. For the egg wash, ensure the yolk is fresh—older yolks yield thinner washes. Foil sealing requires heavy-duty foil—standard foil tears during removal. Pre-sifted flour saves time, but if you skip this, whisk the flour vigorously to aerate. The sugar in the dough prevents gluten development while adding subtle sweetness—never omit it.

Store dough discs between parchment paper in the fridge for up to 3 days or freeze for 3 months. Foil-sealed crusts can be pre-baked and frozen for 2 weeks—thaw at room temperature before filling. Reheating? Brush with cream and bake at 375°F for 5-8 minutes to refresh crispness. Leftovers? Crumble over ice cream or use as a tart base—this crust is too good to waste.

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

This method delivers the flakiest, most reliable all-butter crust you'll ever make.

In a large bowl, combine the 2.5 cups All-Purpose Flour, 0.5 tsp Granulated Sugar, and 0.5 tsp Diamond Crystal Kosher Salt. Whisk briefly to distribute evenly. Add the 1 cup Unsalted Butter (cold and cubed) and use a pastry cutter or two forks to work the butter into the flour until the mixture resembles coarse crumbs with some pea-sized butter pieces remaining.

I press down with my fingers between cuts to ensure even distribution—this prevents pockets of dry flour that can lead to tough crust. The goal is to create a texture similar to wet sand, where the butter coats the flour without melting. If the mixture feels too dry, it's okay; we'll add the ice water next.

In a separate small bowl, combine the 0.33 cup Ice Water and 1 tbsp Heavy Cream. Add this mixture to the flour-butter combination, 1 tablespoon at a time, using a fork to gently stir after each addition. Stop when the dough just comes together when pressed—it should hold its shape but not be sticky to the touch.

This precise hydration is critical. Too much water develops gluten, making the crust tough. Too little results in dry, crumbly dough that won't hold together. The ice water prevents the butter from melting during mixing, which is why we chill it beforehand. If the dough feels slightly dry after mixing, add just 1 teaspoon more ice water.

Turn the dough onto a lightly floured surface and gently shape it into a 1-inch thick disk. Wrap it tightly in the 1 sheet Aluminum Foil and refrigerate for at least 1 hour (up to 2 days). The foil prevents the dough from drying out and allows for even chilling.

Chilling is non-negotiable here—it firms up the butter, preventing it from melting during rolling and baking. I press the foil-wrapped dough flat against the refrigerator shelf to ensure even cooling. The dough should be cold but pliable when ready to roll. If it's too hard, let it sit at room temperature for 5-10 minutes before proceeding.

On a lightly floured surface, roll the chilled dough into a 12-inch circle, about ⅛-inch thick. If the dough resists rolling, let it rest for 5 minutes to relax the gluten. Transfer the rolled dough to a 9-inch pie dish by gently rolling it onto a rolling pin, then unrolling it into the dish.

Here's where the foil comes into play again: use it to carefully lift and position the dough without tearing. Press the edges gently against the pie dish, then trim any excess dough with kitchen shears. The foil-sealed method prevents shrinking during baking, which is why this crust stays perfectly shaped even after filling and baking.

Preheat your oven to 375°F. Line the chilled dough with parchment paper, then fill it with dried beans or pie weights to prevent puffing. Bake for 15 minutes. Remove the weights and parchment, then prick the bottom all over with a fork. Return to the oven for 5-7 minutes until the crust is golden brown and set.

This two-stage baking creates the signature flakiness by allowing steam to escape while maintaining the butter's integrity. The foil-sealed method ensures even baking without soggy bottoms. For extra shine, brush the baked crust with a mixture of the 1 whole Large Egg Yolk and 1 tbsp Granulated Sugar diluted with 1 tbsp Heavy Cream. Bake for an additional 3-5 minutes until the sugar glaze is set.

Pro cooking tips for perfect results

Butter Temperature Control

Cold butter is non-negotiable—use Plugrá or Land O'Lakes cultured butter straight from the fridge, cut into ½-inch cubes. If your kitchen runs warm, freeze the butter for 10 minutes before cubing. The butter should feel firm but yield slightly when pressed.

I test by pinching a cube between fingers—it should hold its shape but not feel rock-hard. If it melts during mixing, your dough will lose flakiness. 🧈

Foil-Sealed Edge Trick

This is the secret to perfect edges: after rolling the dough into your pie dish, press a 1-inch strip of heavy-duty aluminum foil around the crust's perimeter, sealing it to the dish. This prevents shrinking during baking while creating a clean, golden edge.

I use Reynolds Heavy-Duty Foil because it's sturdy enough to hold shape. Remove the foil 5 minutes before the final bake to let the edges crisp.

Dough Hydration Balance

The ice water + heavy cream combo is key—never substitute with room-temperature liquids. Measure the water precisely using the ice cube method: fill a ⅓-cup measure with ice, top with water, then stir. This ensures 33 fluid ounces of liquid without melting.

Too much water = tough crust; too little = dry, crumbly dough. I add the liquid 1 tablespoon at a time, mixing gently with a fork until the dough just holds together when pressed.

Rolling Pin Technique

Use a light touch when rolling—press down just enough to maintain ⅛-inch thickness. I rotate the dough 90 degrees after every 2-3 strokes to prevent uneven thickness. For stubborn dough, let it rest 5 minutes between rolls.

Transfer to the pie dish using a rolling pin and foil: roll the dough onto the pin, then unroll it directly into the dish. This minimizes handling and tears. A 12-inch circle fits perfectly in a 9-inch pie dish with proper trimming.

Blind-Baking Mastery

For flaky layers, never skip the parchment paper during blind-baking. Use dried beans or pie weights to create even pressure. Bake the first 15 minutes with weights, then remove them and prick the bottom with a fork.

This allows steam to escape while keeping the butter intact. The 5-7 minute final bake without weights ensures crispness. For extra shine, brush with egg wash (yolk + sugar + cream) after removing the foil.

Oven Preheating

Preheat your oven to 375°F for at least 15 minutes before baking—this ensures even heat distribution. I place a pie dish filled with water on the middle rack while preheating to maintain consistent temperature.

For convection ovens, reduce temperature by 25°F to prevent over-browning. The foil-sealed edges protect against hot spots, but convection helps crisp the top faster. Always bake on the middle rack for uniform results. 🔥
