In this blog, we’ll explore the origin of tarte au citron, the ingredients you need, a step-by-step recipe, and some tips for achieving perfection.

A Little History of Tarte au Citron

Lemons have been a prized fruit since ancient times, and the French turned their love for citrus into this elegant tart centuries ago. The modern version gained popularity in the 19th century, especially in southern France where citrus fruits were abundant. Today, tarte au citron is a staple in French bakeries, often served plain or topped with a fluffy meringue (tarte au citron meringuée).

Ingredients for Tarte au Citron

For the pastry crust (pâte sucrée):

All-purpose flour – 200 g (about 1 ½ cups)

Unsalted butter – 100 g (cold, cubed)

Powdered sugar – 80 g (⅔ cup)

Egg yolk – 1

Cold water – 2–3 tbsp

A pinch of salt

For the lemon filling:

Fresh lemon juice – 120 ml (about ½ cup, from 3–4 lemons)

Lemon zest – from 2 lemons

Sugar – 150 g (¾ cup)

Eggs – 3 large + 2 yolks

Heavy cream – 100 ml

Unsalted butter – 80 g (softened, cut into pieces)

Optional: a dusting of powdered sugar or a thin meringue topping.

Step-by-Step Recipe

1. Prepare the Pastry Dough

In a bowl, mix flour, powdered sugar, and salt.

Add cold butter cubes and rub with your fingertips (or pulse in a food processor) until the mixture looks sandy.

Add the egg yolk and cold water, mix until dough just comes together.

Wrap in plastic wrap and chill for at least 30 minutes.

2. Bake the Crust (Blind Baking)

Preheat oven to 180°C (350°F).

Roll out the dough on a floured surface and line a tart pan (9-inch).

Prick the bottom with a fork, cover with parchment paper, and fill with baking weights (or beans).

Bake for 15 minutes, remove weights, then bake another 10 minutes until lightly golden.

Let cool.

3. Make the Lemon Filling

In a saucepan, whisk together eggs, yolks, sugar, lemon juice, and zest.

Cook over medium-low heat, stirring constantly, until mixture thickens and coats the back of a spoon (about 8–10 minutes).

Remove from heat, whisk in butter pieces until smooth, then stir in cream.

4. Fill and Bake

Pour lemon filling into the cooled tart shell.

Bake at 160°C (320°F) for 10–12 minutes just to set the filling.

Cool completely before slicing.

5. Serve

Dust with powdered sugar, garnish with lemon slices, or serve plain for a refined look.

Chill slightly before serving for best texture.

Tips for the Perfect Tarte au Citron

Don’t rush the filling – cook it gently or it may curdle.

Blind-bake thoroughly – a crisp crust prevents sogginess.

For extra shine – glaze the top with a little warmed apricot jam.

Variation – add a meringue topping and torch it for a tarte au citron meringuée.

Serving Suggestions

Serve with a dollop of whipped cream.

Pair with tea or champagne for a luxurious experience.

Add fresh berries on top for a colorful twist.
