Delia Smith Lemon Meringue Pie Recipe, Made at Home

Delia Smith’s lemon meringue pie is a classic British dessert: crisp shortcrust pastry filled with tangy lemon custard and topped with a cloud of browned meringue. This version follows the familiar style, with a fully baked pastry shell and a thick, glossy filling that balances sweet meringue with sharp citrus.

Ingredients

For the pastry: 1⅓ cups (170 g) all-purpose flour, plus a little for rolling
7 tablespoons (100 g) cold unsalted butter, cut into cubes
2 tablespoons (25 g) granulated sugar
1 large egg yolk
2–3 tablespoons (30–45 ml) cold water
For the lemon filling: 1 cup (200 g) granulated sugar
⅓ cup (40 g) cornstarch
1½ cups (360 ml) water
Finely grated zest of 2 lemons
½ cup (120 ml) fresh lemon juice, from about 2–3 lemons
3 large egg yolks, lightly beaten
2 tablespoons (28 g) unsalted butter
For the meringue: 4 large egg whites, at room temperature
¾ cup (150 g) granulated sugar

Instructions

Make the pastry. In a bowl, rub the flour and cold butter together with your fingertips until the mixture resembles coarse crumbs. Stir in the sugar, then the egg yolk and 2 tablespoons (30 ml) cold water. Mix just until the dough comes together, adding the remaining water a teaspoon at a time if needed. Shape into a flat disc, wrap, and chill for 30 minutes.
Line and blind-bake the shell. Heat the oven to 375°F (190°C). On a lightly floured surface, roll the pastry into a circle about 12 inches (30 cm) across. Fit it into a 9-inch (23 cm) pie plate, trim and crimp the edge, then prick the base with a fork. Line with parchment and fill with pie weights or dry beans. Bake for 15 minutes, remove the weights and parchment, then bake another 8–10 minutes until dry and lightly golden. Cool while preparing the filling. Keep the oven on.
Cook the lemon filling. Whisk the sugar and cornstarch in a medium saucepan. Gradually whisk in the water until smooth, then add the lemon zest and juice. Bring to a boil over medium heat, whisking constantly. Once thick and bubbling, cook for 1 minute, continuing to whisk. Remove from the heat.
Temper the yolks. Slowly whisk about ½ cup (120 ml) of the hot lemon mixture into the beaten yolks. Pour the yolk mixture back into the saucepan in a thin stream, whisking continuously. Return to medium-low heat and cook for 2 minutes, stirring, until very thick. Remove from the heat and stir in the butter until melted. Pour the filling into the baked pastry shell and spread evenly.
Make the meringue. In a clean, dry bowl, beat the egg whites until foamy and soft peaks form. Add the sugar gradually, about a tablespoon at a time, beating until the meringue is glossy and holds stiff peaks. Spread it over the hot filling, making sure it reaches and seals against the pastry edge; swirl the top with the back of a spoon.
Bake and cool. Bake at 375°F (190°C) for 12–15 minutes, until the peaks are lightly browned. The USDA FSIS safe minimum temperature for egg dishes is 160°F (71°C); if checking, insert a food thermometer into the filling without touching the pan. Cool on a rack for 1 hour, then refrigerate for at least 1 hour before slicing. Allow about 3 hours 15 minutes total, including pastry chilling and cooling.

Tips

Keep the pastry ingredients cold and handle the dough briefly. Overworking it can make the crust tough, while warm butter can cause it to slump in the oven.
Use fresh lemon juice for the clearest, brightest flavor. Bottled juice works in a pinch, but it can taste less aromatic; keep the zest if possible.
Spread the meringue over the filling while it is still hot and press it right to the crust. This helps reduce the gap that can form between the topping and filling.
Make sure the bowl and beaters for the egg whites are clean and grease-free. Even a little yolk or oil can stop the whites from whipping to full volume.

Serving Suggestions

Serve chilled or cool, cut with a sharp knife wiped clean between slices. The pie is rich and sweet, so it needs little alongside it; offer unsweetened tea or coffee, or a small spoonful of fresh berries. For neater slices, chill the pie thoroughly and lift each piece carefully with a thin pie server.

Variations

For a slightly sharper filling, increase the lemon zest or replace 1 tablespoon (15 ml) of the water with extra lemon juice. Avoid adding a large amount of juice without adjusting the cornstarch, since the filling may not set. A graham cracker crust can replace the pastry shell; press 1½ cups (150 g) fine crumbs mixed with 5 tablespoons (70 g) melted butter into the pie plate and bake at 350°F (175°C) for 8–10 minutes before filling. The result is less traditional and has a sweeter, crunchier base.

Storage and Reheating

Because the pie contains eggs, refrigerate it within 2 hours of baking or serving. Once cooled, cover loosely and keep refrigerated for up to 2 days; the meringue may soften or release a little moisture over time. Lemon meringue pie is best served cold and is not suitable for reheating, which can make the topping collapse. Freezing is not recommended because thawed meringue can become watery and the pastry can lose its texture.

Frequently Asked Questions

Can I make lemon meringue pie a day ahead?
Yes, but it is best made the day you plan to serve it, since meringue gradually softens in the refrigerator. If making it ahead, chill it uncovered until the topping feels dry, then cover loosely and serve within 24 hours.

Why is my lemon filling runny?
The cornstarch mixture may not have boiled long enough to activate and thicken fully, or the filling may not have cooled long enough. Bring it to a full boil while whisking and cook for 1 minute before adding the tempered yolks.

Why does my meringue weep?
Weeping can happen if sugar is not fully dissolved, the whites are under- or over-beaten, or the topping cools separately from the filling. Add sugar gradually, beat to glossy stiff peaks, and spread the meringue onto hot filling, sealing it to the crust.

Can I use a store-bought pie crust?
Yes. Blind-bake a 9-inch crust according to its package directions until fully baked and lightly golden, then add the hot filling and continue with the meringue steps.

How can I tell when the meringue is ready?
It should look glossy, hold stiff peaks when the beater is lifted, and have lightly browned tips after baking. For egg-dish safety, the filling should reach 160°F (71°C), measured with a food thermometer.

Can I use leftover egg whites for something else?
Yes. Refrigerate them in a clean, covered container and use within 2 days, or freeze them in a labeled airtight container. Thaw frozen whites in the refrigerator before using.
