The Story Behind the Pie: A Keto-Friendly Masterpiece

The Keto Lemon Meringue Pie is more than just a dessert; it’s a testament to the versatility of keto cooking. Born out of the desire to enjoy classic flavors while maintaining a low-carb lifestyle, this pie is a labor of love. The inspiration comes from the traditional lemon meringue pie, but with a twist that makes it a guilt-free pleasure.

One of the key ingredients in this pie is almond flour, a staple in keto baking. Almond flour is not only low in carbs but also high in healthy fats and fiber, making it an excellent alternative to traditional wheat flour. Another star of the show is erythritol, a sugar alcohol that sweetens without the carbs or calories, ensuring that this pie remains keto-friendly.

The lemon filling is where the magic happens. Fresh lemon juice and zest provide that unmistakable zesty flavor, while the use of xanthan gum as a thickener keeps the texture smooth without adding carbs. The filling is rich in flavor yet light on carbs, making it perfect for those on a ketogenic diet.

Completing the pie is the meringue topping, a fluffy cloud of sweetness that’s sugar-free and stable, thanks to the cream of tartar. It’s the perfect finish to a pie that’s as much a pleasure to look at as it is to eat.

Keto Lemon Meringue Pie Crust

Perfecting the Method: Tips for a Flawless Keto Lemon Meringue Pie

Creating the Perfect Crust: The crust is the foundation of any great pie, and this keto version is no exception. When preparing the crust, ensure that your butter is melted but not too hot. This will help you achieve a consistent dough that presses easily into the pie plate without falling apart. Bake until golden for that irresistible crunch.

Mastering the Filling: The lemon filling is the heart of the pie, and getting it right is crucial. When tempering the egg yolks, add the hot mixture slowly and whisk vigorously to prevent the eggs from scrambling. Patience is key here; take your time to achieve a smooth, velvety filling.

Whipping up the Meringue: For a meringue that stands tall, ensure your bowl and beaters are completely clean and dry. Any trace of grease can prevent the egg whites from reaching their full volume. Add the erythritol gradually while beating to stiff peaks for a glossy, stable meringue that will hold its shape in the oven.

Variations to Spice Up Your Keto Lemon Meringue Pie

Lime Meringue Twist

For a tropical take on the classic, substitute lemon juice and zest with lime. This variation offers a refreshing change that’s perfect for summer gatherings or when you’re simply in the mood for something different.

Berry Infusion

Add a layer of keto-friendly berry compote under the lemon filling for an extra burst of flavor. Berries like raspberries and blackberries offer a tart contrast that complements the lemon beautifully.

Chocolate Almond Crust

Enhance the crust by adding unsweetened cocoa powder to the almond flour mixture. The chocolate flavor pairs wonderfully with the lemon filling, creating a dessert that’s both decadent and keto-friendly.

Substitutions for Your Keto Lemon Meringue Pie

Monk Fruit Sweetener: If erythritol isn’t your preferred sweetener, monk fruit sweetener is an excellent alternative. It’s natural, low in carbs, and has a similar sweetness level, making it an easy swap in this recipe.

Coconut Cream: For a dairy-free option, replace the butter in the filling with coconut cream. This substitution not only caters to those with dairy sensitivities but also adds a subtle coconut flavor that pairs well with lemon.

Chia Seed Jam: If you’re adding a berry layer to your pie, consider using chia seed jam as a healthier, low-carb alternative to traditional jams. It’s easy to make and adds fiber to your dessert.

FAQs About Keto Lemon Meringue Pie

Q: Can I make this pie ahead of time?
A: Absolutely! You can prepare the crust and filling a day in advance. Just add the meringue and bake before serving to ensure it’s fresh and crisp.

Q: How do I store leftovers?
A: Store any leftover pie in the refrigerator, covered, for up to 3 days. The meringue may weep slightly over time, but it will still be delicious.

A: You can freeze the pie without the meringue topping for up to 1 month. Thaw in the refrigerator and add fresh meringue before serving.

  • ½ cup unsalted butter, melted 113g / 4 oz
  • 1 tablespoon erythritol 12g / 0.42 oz

For the Filling:

  • 1 cup water 240ml / 8.12 fl oz
  • 1 cup erythritol 200g / 7.05 oz
  • 5 large egg yolks
  • ½ cup fresh lemon juice 120ml / 4.06 fl oz
  • 1 tablespoon lemon zest 6g / 0.21 oz

For the Meringue:

  • 5 large egg whites
  • ¼ teaspoon cream of tartar 0.6g / 0.02 oz
  • cup erythritol 67g / 2.36 oz


  • Prepare the Crust: Preheat your oven to 350°F (175°C). In a mixing bowl, combine almond flour, coconut flour, melted butter, erythritol, and salt. Press the mixture into the bottom and up the sides of a 9-inch pie plate. Bake for 10 minutes or until golden. Allow to cool.
  • Make the Filling: In a medium saucepan, combine water, erythritol, and lemon zest. Bring to a simmer over medium heat. In a separate bowl, whisk egg yolks and slowly temper them by adding a small amount of the hot mixture, whisking constantly. Pour the tempered yolks back into the saucepan, stirring continuously.
  • Thicken the Filling: Add lemon juice and xanthan gum to the saucepan. Continue cooking until the mixture thickens. Remove from heat and whisk in butter until fully incorporated. Pour the filling into the cooled crust.
  • Create the Meringue: In a clean, dry bowl, beat egg whites with cream of tartar until soft peaks form. Gradually add erythritol and continue beating until stiff peaks form.
  • Assemble and Bake: Spoon the meringue over the lemon filling, spreading to the edges to seal. Bake for 15 minutes or until the meringue is golden brown. Turn off the oven and leave the pie inside to cool gradually for 1 hour to prevent the meringue from collapsing.
  • Chill and Serve: Refrigerate the pie for at least 3 hours before serving to allow it to set completely.

The erythritol can be swapped for another keto-friendly sweetener if preferred.
