This Vegan Tart au Citron (also known as a Vegan Lemon Tart) is the perfect dessert for lemon lovers. Get the recipe below.

What is a Vegan Tart au Citron?

If you love citrus desserts and follow a plant based or vegan diet, you're in for a treat! This Vegan Tart au Citron is a spin on the classic French lemon tart. It is the perfect blend of zesty lemon flavour and a creamy, luscious filling.

A traditional Tart au Citron, has a buttery crust and rich, egg-based custard filling and is a popular dessert in French patisserie. With some simple swaps you can make a delicious vegan alternative.

For this recipe I take my tried and tested vegan shortcrust pastry recipe and use it to make the tart case.

I then make a "custard" from coconut cream, sugar and lemons. You'll find lots of recipes on the internet, set their lemon filling with cornstarch (aka corn flour) but, my husband is allergic so I have to be more creative. Instead, I set my filling with agar powder. It's a simple way of setting fillings such as this and gives great results every time.

How to make vegan shortcrust pastry

You'll need just 4 ingredients to make the pastry for this tart. You'll need vegan butter, plain flour, plant milk and, because it's a sweet pastry case, caster sugar.

To make the pastry you use the "rubbing in" method which involves rubbing the fat and flour between your fingers until it resembles breadcrumbs. You should only be using your finger tips - a top tip is your palms should be entirely clean when you're finished.

To bring the big lumps of fat to the top of the bowl you can give the bowl a shake and they will all appear! You can then focus on rubbing these into the remaining flour.

The caster sugar is then added and stirred throughout the fat and flour breadcrumbs before the plant milk is added to bring the dough together. You want to add the plant milk sparingly just so that it comes together. You don't want it to be sticky.

Once you've got a ball of dough it is important to chill it in the fridge. You can then roll it out and line your tart tin, blind bake and then it's ready to fill.

How to make a vegan lemon tart filling

To make the filling, all you need to do is heat the coconut cream, caster sugar and lemon juice in a pan. Once the caster sugar has dissolved, slowly bring the mix up to a simmer. In the meantime, dissolve the agar powder in a couple of teaspoons of water.

When the mixture has just come up to a simmer, add the dissolved agar powder and cook for 2 minutes until it's just starting to thicken.

Leave the lemon mix to cool slightly before pouring into the tart case.

Top tip

You're going to need to chill your vegan lemon tart for a couple of hours, or overnight, to ensure it sets. Make sure you've left it to cool on the counter top long enough that it has already set slightly, otherwise when you move it, you risk spilling it!

Serving suggestions

This Vegan Tart au Citron has a punchy, zesty flavour. I think it's best paired with some simple, vegan whipped cream.

To make the tart case
