Zesty Mediterranean Sugar-Free Lemon Pie with Almond Crust
This pie happens when the Barcelona sun hits my balcony just right and I need something that tastes like that light — bright, sharp, utterly refreshing. Not a heavy chocolate moment. A lemon moment.
The filling is genuinely silky. The nut crust is buttery and holds its shape properly when sliced. The whole thing looks like something from a patisserie, which I admit is part of the appeal.
The technique for the lemon curd requires patience and constant whisking — but the result is a filling that sets into something far more elegant than a basic baked cheesecake. Worth every minute of stirring.

Ingredients
Serves 8 slices · Scale as needed
- 200g (2 cups) ⇄ almond flour — the pastry swap ⇄ the swap
- 45g (3 tbsp) melted butter (for crust)
- 1 tbsp + 100g ⇄ monk fruit sweetener (crust + filling) — the sweetener swap ⇄ the swap
- ¼ tsp sea salt
- 120ml (½ cup) fresh lemon juice (about 3 lemons)
- 2 tbsp lemon zest
- 3 large eggs
- 60g (¼ cup) unsalted butter, cubed (for filling)
Instructions
- 1
Preheat oven to 175°C (350°F) and grease a 9-inch pie dish.
- 2
In a medium bowl, mix the almond flour, melted butter, 1 tablespoon of monk fruit, and salt until crumbly.
- 3
Press the mixture firmly into the bottom and up the sides of the pie dish. Bake for 10–12 minutes until golden. Let cool completely.
- 4
In a small saucepan, whisk together the lemon juice, lemon zest, eggs, and remaining monk fruit.
⇄ Swap NoteMonk fruit provides a clean, sharp sweetness that balances lemon acidity perfectly — without the gritty texture that other sweeteners can leave in a delicate curd.
- 5
Cook over low heat, whisking constantly, until the mixture thickens enough to coat the back of a spoon — about 8–10 minutes. Do not rush this.
- 6
Remove from heat and whisk in the cubed butter one piece at a time until the curd is smooth and glossy.
- 7
Pour the lemon curd into the cooled crust and smooth the top.
- 8
Refrigerate for at least 4 hours — overnight is better — before slicing.
Why I Made This Swap
A classic lemon tart or pie contains around 26g of sugar per slice, mostly from the refined sugar in the lemon curd and sweet pastry crust. Monk fruit provides the clean, sharp sweetness that perfectly balances fresh lemon without the gritty texture that other sweeteners can leave in a delicate curd. The almond flour crust adds protein and healthy fats while remaining completely gluten-free.
Common Mistakes
- Cooking the curd over too-high heat. The eggs will scramble. Low heat only, constant whisking, full attention. This is not a recipe for multitasking.
- Pouring the curd into a warm crust. The crust must be completely cool before the filling goes in. A warm crust will make the butter in the curd separate.
- Not chilling long enough. The filling sets fully only after 4 hours minimum. Overnight gives you the cleanest, most elegant slices.
Storage
Keep refrigerated for up to 4 days. Cover loosely with cling film to protect the surface of the curd.

Frequently Asked Questions
Can I make individual tarts instead of one large pie?
Yes — divide the crust mixture between 8 individual tart tins and reduce baking time to 8 minutes. Same curd quantity.
My curd isn't thickening — what's happening?
Keep going. It often feels like nothing is happening, then it all comes together quite quickly. Low heat and patience.
Can I add a meringue top?
A monk-fruit sweetened meringue works beautifully on top. Torch it before serving for the full effect.
