Sugar Free Lemon Meringue Pie
Okay. Let’s talk about drama.
Not life drama. Dessert drama.
Because Lemon Meringue Pie is not a quiet dessert. It has layers. It has attitude. It has a cloud of toasted meringue on top like it’s walking a runway. And now? It’s sugar free. Which means you get all the tangy-sweet glory without the sugar overload.
This pie is bright, silky, lightly sweet, and topped with fluffy golden meringue that looks like you tried way harder than you actually did. We love that.
Let’s make something that’s bold, zesty, and slightly theatrical.
Why This Recipe Is Awesome
First: that lemon filling. It’s smooth, glossy, and perfectly balanced between sweet and tart. Not mouth-puckering. Not bland. Just right.
Second: the meringue. Light. Fluffy. Toasted peaks. It’s basically edible clouds.
Third: it’s sugar free. So you can enjoy a slice without that “why did I eat half the pie?” regret spiral.
Also? It looks impressive. People will assume you spent hours. You didn’t. You just followed directions like a responsible legend.
Ingredients You’ll Need
We’re breaking this into three parts because we are professionals now.
For the Crust:
- 1½ cups almond flour (or regular flour if preferred)
- 3 tablespoons melted butter
- 2 tablespoons sugar-free sweetener
- Pinch of salt
(You can also use a store-bought sugar-free crust if you’re in a “minimal effort” mood.)
For the Lemon Filling:
- 1 cup fresh lemon juice (about 4–5 lemons)
- 1 tablespoon lemon zest – This is where the real flavor lives.
- ¾ cup sugar-free sweetener (granulated, 1:1 substitute)
- 4 large egg yolks
- 2 tablespoons cornstarch
- 2 tablespoons butter
- ½ cup water
For the Meringue:
- 4 large egg whites (room temperature)
- ½ cup powdered sugar-free sweetener
- ½ teaspoon cream of tartar
- ½ teaspoon vanilla extract
Step-by-Step Instructions
1. Make the crust.
Preheat oven to 350°F (175°C).
Mix almond flour, melted butter, sweetener, and salt. Press firmly into a pie dish.
Bake for 10–12 minutes until lightly golden. Let it cool completely.
2. Make the lemon filling.
In a saucepan, whisk lemon juice, zest, sweetener, cornstarch, and water. Heat over medium.
Stir constantly until it starts to thicken. Don’t walk away. Lemon filling waits for no one.
In a separate bowl, whisk egg yolks. Slowly pour a little of the hot mixture into the yolks while whisking (this tempers them so they don’t scramble). Then pour everything back into the saucepan.
Cook another 2–3 minutes until thick and glossy. Remove from heat and stir in butter.
Pour the filling into the cooled crust.
3. Make the meringue.
In a clean bowl, beat egg whites and cream of tartar until soft peaks form.
Gradually add powdered sugar-free sweetener. Keep beating until stiff, glossy peaks form. Add vanilla at the end.
Your bowl must be completely grease-free. Even a little oil ruins meringue dreams.
4. Assemble and bake.
Spread meringue over the warm lemon filling. Make sure it touches the crust edges—this prevents shrinking.
Use a spoon to create dramatic swirls and peaks. Be artistic. This is your moment.
Bake at 350°F (175°C) for 10–15 minutes until golden on top.
Let cool completely before slicing. Yes, completely. Cutting early equals lemon lava.
Common Mistakes to Avoid
Cutting the pie too soon.
You’ll get runny filling. Patience = clean slices.
Not sealing the meringue to the crust.
If you don’t spread it to the edges, it shrinks while baking. Rookie mistake.
Overcooking the filling.
Too much heat makes it rubbery. Keep it smooth and gentle.
Using cold egg whites.
Room temp whites whip better. They just do.
Under-whipping the meringue.
Soft peaks are cute. Stiff peaks are necessary.
Alternatives & Substitutions
- No almond flour? Use a traditional pie crust or crushed sugar-free cookies.
- Want it dairy-free? Swap butter with plant-based butter.
- Extra tart lover? Add more zest for punch.
- No cornstarch? Arrowroot powder works too.
- Torch instead of bake? Yes! Use a kitchen torch to brown the meringue for bakery-level drama.
FYI: This pie tastes even better chilled for a few hours. The texture sets beautifully.
FAQ (Frequently Asked Questions)
Does sugar-free meringue actually work?
Yes! Just use a powdered sweetener designed for baking. It whips up beautifully.
Why is my filling runny?
Either it didn’t cook long enough or you sliced too soon. Let it set properly.
Can I make it ahead of time?
Absolutely. Make it the day before and refrigerate.
Why did my meringue weep (water droplets on top)?
Overbaking or humidity can cause that. It’s still safe to eat—just not as pretty.
Can I freeze lemon meringue pie?
Not recommended. The meringue texture changes when thawed.
Can I make mini pies?
Yes! Use small tart pans for adorable individual servings.
Is it very sweet?
Nope. It’s balanced—bright lemon flavor with gentle sweetness.

Sugar Free Lemon Meringue Pie is bold, bright, and unapologetically extra. It’s sweet, tangy, fluffy, and absolutely worthy of a second slice.
It’s the kind of dessert that makes people pause mid-bite and say, “Wait… this is sugar free?”
Yes. Yes, it is.
Now go whip those egg whites like the baking champion you are. Your dramatic, golden-topped masterpiece awaits.
