August 15 Lemon Meringue Pie Day

Last updated: August 15, 2026

Quick Answer

August 15 Lemon Meringue Pie Day is an annual unofficial U.S. food holiday observed every year on August 15 to celebrate the classic lemon curd and meringue-topped pie. It carries no federal or legal status but is widely recognized by bakeries, food brands, and culinary media. The day gives pie lovers a dedicated reason to bake, buy, or share one of America’s most iconic desserts.

Key Takeaways

August 15 Lemon Meringue Pie Day falls every year on August 15 and is listed across major holiday calendars as a recurring annual observance.
The day is an unofficial food holiday with no congressional act or presidential proclamation behind it.
Lemon meringue pie is made from three components: a blind-baked pastry crust, a cornstarch-thickened lemon curd filling, and a whipped egg-white meringue topping.
Weeping meringue (liquid pooling under the topping) is the most common problem bakers face and is caused by undercooking or applying meringue to a cold filling.
The pie is best eaten the same day it is made; refrigeration causes the meringue to weep and the crust to soften.
Cornstarch can be replaced with arrowroot, tapioca starch, or flour as a thickener in the filling.
Lemon meringue pie differs from key lime pie primarily in the filling base and topping style.
Bakeries typically price a whole lemon meringue pie between $18 and $45 depending on size and location (estimated range based on common retail bakery pricing; individual prices vary).
The day is used as a marketing hook by bakeries, lemon growers, and food media brands.
Related food holidays in August include National Ice Cream Sandwich Day on August 2 and other mid-month culinary observances.

What Is August 15 Lemon Meringue Pie Day?

August 15 Lemon Meringue Pie Day is an annual food holiday in the United States dedicated to celebrating lemon meringue pie. It is an informal, fan-driven observance rather than a government-designated holiday, and it appears on consumer-facing event databases, food media calendars, and bakery promotional schedules each year. [1][3][4]

The day functions as a cultural and culinary marker. Food writers use it to share recipes and history, bakeries use it to run promotions, and lemon industry brands build consumer campaigns around it. For example, Limoneira, a major U.S. lemon grower, highlights August 15 in its “Lemon Holidays in August” content and offers recipes to encourage engagement. [3][4]

August 15 also coincides with Julia Child’s birthday and V-J Day, making it a date that several “on this day” resources treat as particularly notable for food and history enthusiasts. [1][6]

What Is August 15 Lemon Meringue Pie Day?

When Did Lemon Meringue Pie Day Start, and Why August 15?

The precise origin of Lemon Meringue Pie Day is not documented in any official record, and no congressional act or presidential proclamation established it. Like most unofficial food holidays, it appears to have emerged through commercial day registries and food media platforms in the early 2000s, gradually gaining traction as food holiday culture expanded online. [3][4][10]

Holiday Today, National Today, bimCal, and Dayspedia all list August 15 as the fixed annual date without attributing the choice to a specific founder or event. [3][4][5][7] The National Day Calendar’s dedicated page for “National Lemon Meringue Pie Day” describes it as a celebration for pie and lemon lovers but does not reference any founding organization or legal basis. [10]

As for why August 15 specifically: no verified explanation exists. The timing does align with peak summer lemon availability and the height of pie-eating season in the United States, which may have made the date feel natural to whoever first popularized it.

Key point: If someone asks whether this is a “real” holiday, the accurate answer is that it is a widely recognized but entirely unofficial food observance.

How to Make Lemon Meringue Pie from Scratch

A classic lemon meringue pie requires three separate preparations: the pastry crust, the lemon curd filling, and the meringue topping. Each component has its own technique, and the order of operations matters.

The Crust

Use a standard shortcrust or all-butter pie pastry.
Blind-bake the crust before adding filling: line with parchment, fill with pie weights or dried beans, and bake at 375°F (190°C) for 15 minutes, then remove weights and bake another 10 minutes until golden.
A fully baked crust prevents a soggy bottom.

The Lemon Curd Filling

Combine in a saucepan: 1 cup sugar, 3 tablespoons cornstarch, 1.5 cups water, 2 teaspoons lemon zest, and 0.5 cup fresh lemon juice.
Cook over medium heat, stirring constantly, until the mixture thickens and bubbles.
Temper 3 egg yolks by whisking a small amount of the hot mixture into them, then return everything to the pan and cook for 2 more minutes.
Remove from heat, stir in 2 tablespoons butter, and pour into the warm baked crust.

The Meringue

Beat 3 egg whites with a pinch of cream of tartar until foamy.
Gradually add 6 tablespoons sugar, beating to stiff, glossy peaks.
Spread meringue over the hot lemon filling, sealing it to the crust edges completely to prevent shrinking.
Bake at 350°F (175°C) for 12 to 15 minutes until the meringue peaks are golden.

Critical rule: Always spread meringue onto a hot filling. This cooks the underside of the meringue and dramatically reduces weeping.

Lemon Meringue Pie vs. Key Lime Pie: What Is the Difference?

Lemon meringue pie and key lime pie are both citrus-based desserts but differ significantly in filling composition, topping, and texture. Lemon meringue pie uses a cooked, cornstarch-thickened curd made with lemon juice and egg yolks, topped with baked egg-white meringue. Key lime pie uses a no-cook filling of key lime juice, egg yolks, and sweetened condensed milk, typically topped with whipped cream rather than meringue.

Feature	Lemon Meringue Pie	Key Lime Pie
Filling base	Cooked lemon curd with cornstarch	Condensed milk and lime juice
Crust	Shortcrust or all-butter pastry	Graham cracker crumb crust
Topping	Baked egg-white meringue	Whipped cream (usually)
Texture	Firm, sliceable curd; airy topping	Dense, creamy, custardy
Flavor profile	Bright, sharp lemon tartness	Milder, floral lime sweetness

Choose lemon meringue pie if you want a dramatic presentation with a tall, toasted topping. Choose key lime pie if you prefer a denser, creamier dessert that requires less baking technique.

Why Does My Meringue Weep, and How to Prevent It

Meringue weeping (also called “beading” or “sweating”) is the most common lemon meringue pie problem. It happens when liquid seeps between the meringue and the filling, creating a watery layer. There are two distinct causes, and fixing them requires different approaches.

Cause 1: Undercooking. If the meringue is not baked long enough, the egg whites remain partially raw and release moisture over time. Solution: bake at 350°F until peaks are golden, at least 12 minutes.

Cause 2: Cold filling. Spreading meringue onto a cooled filling means the underside of the meringue never fully cooks. Solution: always pour the hot lemon curd into the crust and top it with meringue immediately while the filling is still steaming.

How to prevent meringue from shrinking:

Seal the meringue all the way to the crust edges with no gaps.
Avoid overbeating the egg whites past stiff peaks; overbeaten meringue contracts when baked.
Use cream of tartar (about 0.25 teaspoon per 3 whites) to stabilize the foam.
Do not make meringue on a humid day if possible; moisture in the air weakens the structure.

Common Lemon Meringue Pie Mistakes to Avoid

Even experienced bakers run into problems with this pie. The most common mistakes are predictable and preventable.

Skipping the blind bake: A raw crust under a wet filling will always be soggy. Blind-bake fully before adding any filling.
Not tempering the egg yolks: Adding hot liquid directly to yolks scrambles them. Always whisk a small amount of hot filling into the yolks first.
Using bottled lemon juice: Fresh lemon juice and zest produce a noticeably brighter, more complex flavor. Bottled juice often tastes flat.
Cutting the pie while warm: The filling needs to set completely. Refrigerate for at least 2 hours before slicing, but serve the same day.
Making it too far in advance: The meringue begins to weep within 24 hours, and the crust softens in the refrigerator. Same-day assembly is strongly preferred.

Can You Make Lemon Meringue Pie Ahead of Time?

Lemon meringue pie is best made and served the same day. The meringue starts to weep and the crust softens significantly after 24 hours in the refrigerator, which degrades both texture and appearance.

If advance preparation is necessary, here is the recommended approach:

Bake the crust up to 2 days ahead and store it at room temperature, loosely covered.
Make the lemon curd filling up to 2 days ahead and refrigerate it in a sealed container.
Assemble and bake the meringue on the day of serving, reheating the filling gently before adding the meringue.

This staged approach preserves the quality of each component without compromising the final result.

Lemon Meringue Pie Shelf Life: How Long Does It Last?

A fully assembled lemon meringue pie lasts 2 to 3 days in the refrigerator, but quality declines noticeably after the first day. The meringue weeps, the crust softens, and the filling can become watery. Freezing is not recommended for the finished pie because the meringue collapses and becomes rubbery when thawed.

Room temperature: Do not leave the assembled pie at room temperature for more than 2 hours due to the egg-based components.
Refrigerator: Up to 3 days, loosely covered. Expect quality loss after day 1.
Freezer (filling only): The lemon curd can be frozen for up to 3 months in a sealed container. The assembled pie with meringue should not be frozen.

Lemon Meringue Pie Without Cornstarch: Alternatives

Cornstarch is the standard thickener for lemon meringue pie filling, but it can be replaced with several alternatives. Each substitute behaves slightly differently, so small adjustments may be needed.

Substitute	Ratio (replaces 3 tbsp cornstarch)	Notes
Arrowroot powder	3 tablespoons	Similar texture; do not overcook or it thins out
Tapioca starch	3 tablespoons	Slightly glossier finish; works well
All-purpose flour	4.5 tablespoons	Produces a slightly cloudier, less glossy filling
Potato starch	2.25 tablespoons	Strong thickening power; use less

Choose arrowroot if you want the closest match to cornstarch in texture and clarity. Choose flour if it is the only option available, but expect a less translucent filling.
