Every year, my in-laws have a friend who visits a blueberry farm nearby and provides us with kilos upon kilos of fresh, sweet blueberries. In fact, it ends up being so many blueberries that I often don’t even know what to do with them!
Thankfully, I think that blueberry desserts are some of the best in the world and I will take any excuse to make a blueberry tart.
For this recipe, I’ve let the flavour of the blueberries sing with very few additives to the filling. And to make it even earlier, you can use puff pastry for the crust and form it as a galette – meaning you don’t need a special pan!

How to Make a Blueberry Galette with Puff Pastry
This tart is refreshingly quick and easy – especially if you use store-bought puff pastry.
Even if you’re using homemade puff pastry, if you’ve made it in advance, the assembly of this tart will only take about 15 minutes tops.

Start first by rolling out your pastry. Lightly flour a work surface and roll your pastry in a circular pattern until it’s about 5mm (1/4in) thick and the circle is roughly 30cm (12 in) in diameter – go ahead and trim the pastry if you can’t easily get s square into a circle! But there is no need for it to look perfect, this is a very rustic-looking tart.
Once the pastry is rolled out, set it on a parchment-lined baking sheet and chuck it in the fridge while you mix your filling.

Onto the filling – all you need to do is add a good amount of fresh blueberries to a large bowl. You can use frozen blueberries if you’d like – just make sure that you haven’t defrosted them ahead of time. It will be much easier to mix the filling with blueberries that are still frozen solid.
To the blueberries, add a squeeze of lemon juice, a bit of salt, some brown sugar and a bit of flour to act as a thickening agent once baked. Stir until everything is well combined.

Remove the pastry from the fridge and then pile the filling into the centre of the pastry – making sure to leave a 5cm (2in) border. Then, fold the border of the pastry over the filling.
To ensure you get the most beautiful, golden crust possible, brush the exposed pastry with a beaten egg and then sprinkle with demerara sugar to add a sparkly look – or use granulated sugar if that’s what you have on hand.

Move the tart to a preheated 180°C/350°F and bake for about 30 minutes – you want the pastry to be deeply crisp and golden and the filling to be molten and bubbling.
The hardest part is that you do need to wait until the tart is cooled completely before cutting into it – but fortunately, due to its size, this doesn’t take nearly as long as something like a strawberry rhubarb pie!
