How to Make Keto Lemon Meringue Pie

I’ve included everything below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the Recipe card at the bottom of this post.

1. Heat your kitchen oven to 350°F (175°C) before spraying a 9-inch pie dish lightly with cooking oil.
2. Mix almond flour, melted butter, and sweetener in a medium bowl until crumbly dough forms nicely.
3. Press dough firmly into your pie dish bottom and side surfaces for about 5 minutes carefully.
4. Bake crust for 10 minutes until golden, then cool completely on a wire rack nearby.
5. Whisk egg yolks, lemon juice, lemon zest, sweetener, and butter in a saucepan over medium-low heat.
6. Stir filling constantly for 8–10 minutes until thick enough to coat your spoon back completely.
7. Pour warm lemon curd smoothly into your cooled pie crust base and smooth evenly.
8. Beat egg whites with cream of tartar and sweetener on high speed until stiff peaks hold firmly.
9. Spread meringue gently over filling, sealing edges tightly against the crust perimeter to avoid shrinking.
10. Bake at 350°F (175°C) for 10–12 minutes until meringue peaks turn light golden brown visually.

Pro Tip: Always seal your meringue completely to the outer edge of the pie crust base to prevent shrinkage during cooling!

Common Mistakes to Avoid

• Using granulate sweetener: Always select powdered sweeteners to avoid gritty meringue textures later on.
• Overheating the curd: Keep stove heat low so your egg yolks do not scramble in the saucepan.
• Unsealed meringue edges: Seal meringue directly onto the warm crust edge so it stays stable.

Required Equipment

• Pie Pan: Holds pie shape securely and allows even baking across the base.
• Electric Mixer: Whips egg whites rapidly to achieve gorgeous, airy, stiff white peaks.
• Saucepan: Heats lemon curd evenly to prevent scorching or burning egg yolks.

Caleb’s Recipe Tips

• Fresh lemon choice: Always squeeze real fresh lemons rather than bottled juice for brighter citrus flavor.
• Room temperature eggs: Warm egg whites whip higher and build superior volume during mixing steps.
• Cool crust first: Cool your almond crust before filling to maintain a crisp bottom layer.
• Powdered sweetener swap: Grind granular sweetener in a blender if you run out of powdered options.

Storage Instructions

• Refrigerator storage: Store covered pie inside the fridge for up to 3 days maximum.
• Freezer storage: Freezing is not recommended because meringue loses structural integrity when thawed.
• Containers: Use a deep pie carrier lid to avoid crushing delicate toasted meringue tops.
• Reheating tips: Enjoy chilled straight from your refrigerator for the crispest slice texture.
