Fluffy Meringue on Biscuit Base Lemon Pie

I didn’t try making a lemon meringue pie until I was in my thirties because I thought it would be too hard. Mom always bought hers from the local bakery, saying it was “too fussy” to make at home. The first time I attempted one, I used a pre-made graham cracker crust, and it was… well, let’s just say the dogs wouldn’t even eat it.

That’s because I was going about it all wrong—trying to rush the process and skipping important steps. This biscuit base version, though? It’s become my go-to recipe. The cookie crust is much more forgiving than pastry, and it gives the pie a nice crunch that works really well with the smooth lemon filling.

What Kind of Biscuits Should I Use?

For a lemon meringue pie base, you’ll want to use plain, sweet biscuits that can be easily crushed into fine crumbs. Marie biscuits are a classic choice because they have a light, sweet flavor that won’t overpower the lemon filling, but you can also use graham crackers, digestive biscuits, or vanilla wafers. The key is picking a biscuit that’s crisp and not too thick – avoid anything with cream fillings or chocolate coatings. Just make sure your biscuits are fresh and dry (stale biscuits can make your base taste off), and crush them into very fine crumbs for the best texture in your pie base.

Options for Substitutions

Need to make some swaps? Here’s what you can do with this lemon meringue pie recipe:

• Marie biscuits: Any plain sweet cookie works great here – try graham crackers, digestive biscuits, or even vanilla wafers. Just make sure they’re not too strongly flavored.
• Lemon juice and zest: While fresh lemon juice gives the best flavor, you can use bottled lemon juice in a pinch. For a fun twist, try lime juice and zest, or mix lemon and lime together. Just don’t skip the citrus – it’s what makes this pie special!
• Cornstarch: You can swap cornstarch with arrowroot powder (use the same amount) or potato starch. For the filling, you’ll need to cook it a bit longer with arrowroot to get the right thickness.
• Superfine sugar: Regular granulated sugar works too – just pulse it in a food processor for a few seconds to make it finer. Don’t use powdered sugar as it contains cornstarch and will change the texture.
• Unsalted butter: If you only have salted butter, that’s fine – just skip the pinch of salt in the recipe. For dairy-free options, coconut oil works in the crust, but the filling really needs real butter for the right texture.

Watch Out for These Mistakes While Baking

The biggest challenge when making lemon meringue pie comes from the meringue weeping or becoming grainy – to prevent this, make sure your egg whites are at room temperature and add the sugar gradually while beating, not all at once. A common error is overworking the biscuit base, which can make it too compact and hard to cut – instead, press the mixture gently into the pan with the back of a spoon until just combined. The lemon filling can become lumpy if you don’t whisk constantly while cooking, so keep stirring over medium heat until it thickens smoothly, and strain through a fine-mesh sieve if needed. For the best results, let the lemon filling cool completely before adding the meringue, and make sure to spread the meringue right to the edges of the crust to prevent shrinkage during baking.

What to Serve With Lemon Meringue Pie?

This zesty dessert is perfect on its own, but there are some nice ways to make it even more special! A dollop of fresh whipped cream on the side adds a lovely richness that balances out the tangy lemon filling. For a refreshing summer combo, serve your pie with a scoop of vanilla ice cream or a handful of fresh berries like raspberries or strawberries. If you’re serving this at a dinner party, a cup of hot coffee or Earl Grey tea makes for a perfect pairing – the warm drinks complement the cool, creamy texture of the pie really nicely.

Storage Instructions

Keep Fresh: Your lemon meringue pie will stay best in the refrigerator, covered loosely with foil (avoid plastic wrap as it can stick to the meringue). It’s good for up to 3 days, though the meringue is at its peak on the first day. The base might soften slightly over time, but it’ll still taste great!

Make Ahead: Want to prep in advance? You can make the biscuit base and lemon filling a day ahead, keeping them in the fridge. Just add the fresh meringue topping on the day you plan to serve. This way, you’ll get that perfect, fluffy meringue texture that everyone loves.

Serve: Take the pie out of the fridge about 15-20 minutes before serving to let the flavors develop. Keep in mind that lemon meringue pie doesn’t freeze well – the meringue can become watery and the texture changes quite a bit, so it’s best enjoyed fresh!

Ingredients

For the biscuit base:

• 3.5 oz unsalted butter (melted)
• 8.8 oz plain sweet biscuits (crushed into fine crumbs)
• 1 egg white (lightly beaten)

For the lemon filling:

• 5.3 oz superfine sugar
• a pinch salt
• 1 cup water
• 1.3 oz cornstarch (sifted to remove lumps)
• 1.5 oz unsalted butter (I use Kerrygold for richness)
• 5 egg yolks (room temperature)
• 3/4 cup fresh lemon juice (freshly squeezed preferred)
• zest from 2 lemons (finely grated for maximum flavor)

For the meringue:

• 4 cold egg whites (straight from refrigerator)
• 3 tsp cornstarch (helps stabilize the meringue)
• 7 oz superfine sugar (I use Domino superfine sugar)

Step 1: Prepare the Biscuit Crust Foundation

• 8.8 oz plain sweet biscuits
• 3.5 oz unsalted butter
• 1 egg white

Preheat your oven to 180°C (350°F).

While it heats, crush the biscuits into fine crumbs—I like to use a food processor for a uniform texture that bonds better.

In a separate bowl, lightly beat one egg white until frothy, then combine it with the melted butter and crushed biscuits, mixing until the mixture resembles wet sand.

Transfer this to your 9-inch tart tin and press it firmly into the base and up the sides, creating an even layer.

Bake for 10 minutes until lightly set, then remove and set aside to cool while you prepare the filling.

Step 2: Cook the Lemon Curd Filling

• 5.3 oz superfine sugar
• 1.3 oz cornstarch
• a pinch salt
• 3/4 cup fresh lemon juice
• 1 cup water
• 1.5 oz unsalted butter
• zest from 2 lemons
• 5 egg yolks

In a saucepan, combine the superfine sugar, sifted cornstarch, and pinch of salt.

Add the fresh lemon juice and water, whisking to combine and break up any lumps.

Cook over medium heat, stirring frequently, until the mixture thickens and small bubbles appear on the surface—this takes about 5-8 minutes.

Remove from heat and stir in the butter and finely grated lemon zest, allowing the residual heat to meld the flavors.

Let cool for 2 minutes, then whisk in the room-temperature egg yolks one at a time, stirring constantly to prevent scrambling.

Return the pan to medium heat and cook for exactly 1 minute, stirring gently, bringing the filling to 71°C (160°F) to safely pasteurize the yolks.

Step 3: Assemble and Cool the Pie Base

• lemon curd filling from Step 2
• biscuit crust from Step 1

Pour the warm lemon curd filling directly into the cooled biscuit crust, spreading it evenly.

Let the pie cool at room temperature for 30 minutes—this resting period allows the filling to set slightly and prevents the meringue from weeping, a tip I’ve learned from many pie mishaps.

While the filling cools, prepare your meringue in the next step.

Step 4: Build the Fluffy Meringue Topping

• 4 cold egg whites
• 3 tsp cornstarch
• 7 oz superfine sugar

Remove your 4 cold egg whites from the refrigerator and begin whisking them at medium speed until soft peaks form—this usually takes 2-3 minutes.

Sift the cornstarch directly into the whites and mix on low speed for 15 seconds to incorporate it evenly; the cornstarch helps stabilize the meringue and prevents it from weeping.

Increase the speed to medium and add the superfine sugar one tablespoon at a time, waiting about 20 seconds between each addition—this gradual incorporation creates a glossier, more stable meringue.

Once all sugar is added, scrape down the bowl and continue beating on high speed for another 2-3 minutes until the meringue is glossy and holds stiff peaks that don’t droop.

I find that using Domino superfine sugar gives a noticeably smoother texture than regular granulated sugar.

Step 5: Top, Bake, and Cool the Finished Pie

• meringue from Step 4
• pie with filling from Step 3

Working quickly while the meringue is freshly whipped, scoop it generously onto the lemon filling and spread it to the edges, pressing it slightly against the crust to seal the filling.

Use the back of a spoon or spatula to create decorative peaks across the surface—these peaks brown beautifully and add visual appeal.

Bake for 15-20 minutes until the meringue is golden brown on the peaks, being careful not to overbake or the peaks will darken too much.

Remove from the oven and let the pie cool at room temperature for 2 hours before slicing—this allows the meringue to set fully and the flavors to meld perfectly.
