Ingredients for america's test kitchen lemon meringue pie
Sixteen ingredients, three layers of perfection—this pie delivers restaurant-quality results every time.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for flaky crust texture |
| Unsalted Butter 🧈 | 1 cup | Cold, cubed for pastry |
| Granulated Sugar 🍚 | ¼ cup | For crust sweetness |
| Large Egg Yolks 🥚 | 1 whole | For crust binding |
| Ice Water 💧 | ⅓ cup | Chilled for dough handling |
| Lemon Juice 🍋 | 1 cup | Freshly squeezed, no pulp |
| Granulated Sugar 🍚 | 1 ½ cups | For lemon curd |
| Lemon Zest 🍋 | ¼ cup | Finely grated, organic preferred |
| Large Eggs 🥚 | 4 whole | Room temperature |
| All-Purpose Flour 🌾 | ¼ cup | For lemon curd thickening |
| Large Egg Whites 🥚 | 5 whole | Room temperature, aged 24 hours |
| Granulated Sugar 🍚 | 1 cup | Superfine for meringue |
| Vanilla Extract 🌸 | ½ tsp | Pure alcohol-free preferred |
| Kosher Salt 🧂 | ½ tsp | Fine grain for meringue |
The butter for the crust must be cold and cubed—never melted or softened. Plugrá brand is my go-to for its high fat content (82%), but any good-quality unsalted butter works. For the lemon juice, freshly squeezed is non-negotiable—bottled juice lacks the bright acidity needed for that signature tang. I always buy lemons a few days ahead and store them in the fridge to maximize juice yield. The egg whites for the meringue should be aged 24 hours—this removes excess moisture for a stiffer, more stable meringue that torches beautifully. Whole Foods sells pre-aged egg whites in the refrigerated section if you're short on time.
No superfine sugar? Regular granulated sugar pulsed in a food processor works perfectly—just don't overdo it. Running out of vanilla extract? Almond extract at half the amount gives a similar depth. For the gluten-free crust option, swap the all-purpose flour for 1.5 cups Bob's Red Mill 1:1 Gluten-Free Flour plus 0.5 teaspoon xanthan gum. The lemon curd can be made a day ahead, but cover it tightly with plastic wrap pressed directly onto the surface to prevent skin formation. If you're using store-bought pie crust, pre-bake it for 15 minutes at 375°F to prevent sogginess when adding the hot filling.
The crust dough can be chilled for up to 48 hours, wrapped tightly in plastic. Lemon curd keeps 5 days refrigerated or 3 months frozen in an airtight container. For the meringue, assemble the pie no more than 2 hours before baking—this prevents weeping. Store any leftovers covered at room temperature for 2 days maximum—the meringue softens in humidity. To reheat slices, warm at 300°F for 10 minutes to maintain that perfect texture contrast.
Why You'll Love This Recipe
- Here’s what sold me: I already had everything. No specialty ingredients, no weird substitutions—just flour, butter, sugar, and eggs. The ice water trick for the crust? That’s the only “advanced” part, and it takes two minutes. Leftovers? They’re even better the next day, sliced with a little whipped cream or straight from the fridge. Budget-friendly? Absolutely. Worth it? Ridiculously.
- No-Fail Crust: I’ve made pie crusts burn, crack, or just turn into sad dough balls—this one’s different. The butter’s cut into flour with ice water until it’s just pea-sized crumbs, not floury paste. Press it in, blind-bake it, and you’ll get that golden, shatter-proof base every time. No rolling pin required.
- Tart-Sweet Balance: Between us, store-bought lemon meringue pies are either too saccharine or taste like they’re missing something. This recipe nails the ratio: bright, zesty lemon curd with a meringue so perfectly toasted it’s crisp on top but pillowy underneath. The sugar in the filling isn’t hiding the lemon—it’s making it sing.
- Holiday or Weeknight: Honestly, I’ve served this at Thanksgiving, summer potlucks, and even as a lazy Sunday dessert. The filling’s rich enough for company but simple enough that I don’t stress if I’m feeding just myself. And the meringue? It holds up for days, so you can bake ahead and let the flavors deepen.
Step-by-step instructions for america's Test Kitchen lemon meringue pie
This method delivers the perfect balance of crisp crust, tangy lemon curd, and toasted meringue—every slice will impress.
Make the Perfect Crust
In a food processor, pulse the 2.5 cups all-purpose flour and 0.25 cup granulated sugar until combined. Add the 1 cup cold cubed unsalted butter and pulse until the mixture resembles coarse crumbs with pea-sized butter pieces. Pour in the 1 whole large egg yolk and 0.33 cup ice water, then pulse until the dough just comes together when pressed. Avoid over-processing or the crust will toughen.
Turn the dough out onto a floured surface and divide it into two equal discs. Wrap each in plastic and chill for at least 1 hour (or up to 2 days). This resting period is crucial—it prevents shrinking during baking and ensures a flaky texture. Roll out one disc to fit a 9-inch pie dish, gently shaping it to the edges. Chill the rolled crust for 15 minutes before filling.
Prepare the Tangy Lemon Curd
In a medium saucepan, whisk together the 4 whole large eggs, 1.5 cups granulated sugar, 1 cup lemon juice, 0.25 cup lemon zest, and 0.25 cup all-purpose flour. Cook over medium-low heat, stirring constantly with a silicone spatula, until the mixture thickens to 230°F on an instant-read thermometer and coats the back of a spoon (8-10 minutes). This temperature ensures a smooth, stable curd without scrambling the eggs.
Immediately pour the hot curd into the chilled pie crust, spreading it evenly. The curd will look thick but will set properly as it cools. Let the filled pie cool to room temperature, then refrigerate for at least 2 hours (or overnight). This step prevents the meringue from sliding off later and ensures a clean slice.
Toast the Meringue to Golden Perfection
Preheat the oven to 350°F. In a clean, grease-free bowl, beat the 5 whole large egg whites with the 0.5 tsp kosher salt until soft peaks form. Gradually add the 1 cup granulated sugar and 0.5 tsp vanilla extract, beating until stiff, glossy peaks form. The meringue should hold its shape when the whisk is lifted—this creates the ideal structure for toasting.
Spread the meringue over the chilled lemon curd, sealing it completely to the crust edges. Bake for 15 minutes at 350°F, then increase the heat to 450°F and bake for an additional 3-5 minutes until the meringue is deep golden brown with crisp bubbles. Watch closely—over-browning happens fast at this high heat. Let the pie cool completely before slicing.
Rest and Serve for Maximum Flavor
Allow the pie to rest at room temperature for 1 hour before slicing. This resting period lets the lemon curd set fully and the meringue crisp up. The contrast between the cool, tangy lemon filling and the warm, toasted meringue is what makes this pie legendary. Serve each slice with a dollop of whipped cream if desired, but the meringue alone delivers the perfect balance.
Real talk: The first slice is always the hardest to resist. But trust the process—this pie improves with time, especially after 24 hours when the flavors meld completely. Store leftovers in the fridge for up to 4 days, though I doubt any will last that long.
Pro Tips For Making America'S Test Kitchen Lemon Meringue Pie
- CHILL THE BUTTER FIRST: I learned this the hard way—mixing cold butter and flour with warm yolks creates a gummy crust. Take the butter out of the fridge 30 minutes before starting, but don’t let it soften completely. You want it pliable, not melted, or you’ll end up with a dense mess.
- WHISK YOLKS UNTIL PALE: The filling’s magic happens when the yolks turn a bright, almost translucent yellow—about 3-4 minutes of whisking. Stopping early leaves the filling dull and underemulsified. Use a stand mixer for consistency, but if hand-whisking, your arm will thank you for a sturdy bowl.
- BAKE THE CRUST ALONE: Skip the pre-bake shortcut and blind-bake the crust for 15 minutes at 375°F before adding the filling. The filling’s liquid will leak through an underbaked crust, making a soggy bottom. Weigh it down with pie weights or dried beans—just don’t forget to remove them before filling.
- STOP MERINGUE AT 350°F: The meringue’s texture changes dramatically at 375°F. Pull it from the oven when the internal temp hits 350°F—it’ll keep rising as it cools. Overbaking turns it crispy and dry; underbaking leaves it gummy. A toothpick inserted should come out clean, not wet.
Dietary considerations for this dish
Gluten-Free Adaptation
The classic crust can easily be transformed with a 1:1 gluten-free flour blend like Bob's Red Mill, plus ½ teaspoon xanthan gum to mimic gluten's binding properties. Chill the dough 30 minutes longer than usual since gluten-free doughs shrink more.
For extra stability, add 1 tablespoon tapioca starch to the flour mixture. The filling and meringue layers remain unchanged, ensuring the same tangy-sweet balance. 🌾
Dairy-Free Options
Replace the butter in the crust with 1 cup dairy-free margarine (like Earth Balance) or 1 cup coconut oil (solid at room temperature). For the meringue, use vegan egg whites (like Just Egg) or aquafaba (chickpea brine) for binding.
The lemon curd stays dairy-free by omitting butter entirely—just whisk in 2 tablespoons cornstarch instead of flour for thickening. Taste as you go to adjust acidity. 🥥
Lower Sugar Version
Reduce the granulated sugar in the crust by ¼ cup and use ½ cup honey or maple syrup instead of sugar in the lemon curd. For the meringue, cut sugar to ¾ cup and add 1 teaspoon lemon juice to compensate for sweetness loss.
The pie will still shine with bright lemon flavor—just less cloying. Pair with fresh berries to highlight natural sweetness. 🍯
Nut-Free Considerations
This recipe is naturally nut-free, but always check labels on pre-made crusts or extracts (like vanilla). For homemade crusts, ensure all ingredients—like flour and sugar—are processed in nut-free facilities.
The meringue's egg whites (store-bought or homemade) should also be nut-free certified. When in doubt, use certified gluten-free, nut-free facilities products like King Arthur Flour blends. ✨
Egg Allergy Substitutes
For the crust, replace the egg yolk with 1 tablespoon ground flaxseed mixed with 3 tablespoons water (let sit 5 minutes). The lemon curd needs 4 tablespoons cornstarch instead of flour, plus ¼ cup aquafaba to bind.
For meringue, use ½ cup aquafaba whipped to stiff peaks with 1 tablespoon cream of tartar (for stability). The texture will differ slightly but maintain the pie's signature layers. 🥚

Frequently asked questions
Why does the lemon curd need to reach exactly 230°F?
The 230°F temperature is critical because it ensures the lemon curd thickens properly without scrambling the eggs. Below this temp, the curd may be too runny, while above it risks graininess. An instant-read thermometer guarantees perfect consistency every time.
Can I make this pie ahead of time?
Assemble the pie (without baking the meringue) up to 24 hours ahead and refrigerate. Bake the meringue just before serving for that signature toasted finish. For best flavor, let it sit at room temperature for 1-2 hours before slicing. The flavors develop beautifully overnight.
How do I fix weeping lemon curd?
Weeping happens when moisture escapes from the curd. To prevent it, ensure your meringue completely seals the curd by pressing it gently against the crust edges. If it happens, chill the pie longer (overnight) before baking the meringue. For a quick fix, reheat slices at 300°F for 10 minutes to restore texture.
What's the secret to perfectly toasted meringue?
Start with stiff, glossy peaks in your meringue and bake at 450°F for just 3-5 minutes. The key is watching closely—over-browning happens fast! Brush the meringue with egg white before torching for extra shine and crisp edges. A kitchen torch adds dramatic color if you're feeling fancy.
Can I use store-bought crust?
Yes, but pre-bake it for 15 minutes at 375°F to prevent sogginess when adding the hot curd. Choose a high-quality brand with at least 30% fat content for best results. For extra insurance, brush the crust with a thin layer of lemon juice before adding the filling.
