Ingredients You’ll Need
This homemade tart recipe uses simple ingredients that come together into a creamy, citrusy dessert with a wonderfully smooth texture.
Sour Cream Pastry
- 250 g plain (all purpose) flour
- 200 g cold butter, cubed
- 125 ml sour cream
This pastry is wonderfully tender and slightly tangy, giving the tart a softer, more balanced bite than many traditional pastry crusts.
Lemon Mascarpone Filling
- 250 g fresh ricotta cheese
- 250 g mascarpone cheese
- 2/3 cup sugar
- 2 large whole eggs
- 2 large egg yolks
- 1 tablespoon finely grated lemon rind
- 80 ml fresh lemon juice
The ricotta and mascarpone combination creates a creamy homemade filling that feels smooth, rich, and beautifully balanced.
Candied Lemon Topping
- 1 lemon, thinly sliced into rounds
- 1/3 cup caster sugar
- 1/3 cup water
This glossy citrus topping adds a bright finishing touch that makes the tart feel extra special for a family dessert table.
How to Make It
Prepare the Sour Cream Pastry
Place the flour and cold butter into a food processor and pulse until the mixture resembles coarse breadcrumbs.
Add the sour cream and pulse again just until the dough comes together into a soft ball. This simple step keeps the crust tender and easy to handle.
Form the dough into a flat disk, wrap with cling film, and refrigerate for 20 minutes.
Roll and Chill the Tart Shell
Roll the chilled dough out to fit a 25 cm round tart pan.
Gently press it into the pan and use a fork to poke small holes across the pastry.
Chill the prepared shell again for about 60 minutes, which helps the crust hold its shape during baking and creates a crisp, delicate base.
Blind Bake the Crust
Preheat the oven to 200°C (390°F).
Line the pastry with a double layer of foil and fill it with sugar to weigh it down. Sugar works beautifully as a blind baking weight because it settles neatly into the corners.
Bake for 15 minutes, then remove the foil and sugar.
Return the crust to the oven for another 5 minutes until it becomes lightly golden and dry.
Reduce the oven temperature to 170°C (340°F).
Make the Lemon Mascarpone Filling
Place the ricotta and mascarpone into a food processor and blend until completely smooth.
Add the sugar, eggs, egg yolks, lemon rind, and fresh lemon juice.
Process again until the mixture becomes silky and creamy. The combination creates a luxuriously smooth filling that feels lighter than many traditional custard-style tart recipes.
Bake the Tart
Place the tart shell on the middle oven rack.
Carefully pour the lemon mascarpone filling into the pastry case.
Bake for about 30 minutes until the filling is just set.
The center should still have a gentle wobble when the pan is lightly shaken this helps the tart stay creamy and soft once chilled.
Allow the tart to cool in the pan, then refrigerate until fully set.
Make the Candied Lemon Slices
Add the sugar and water to a frying pan over medium heat.
Cook until the mixture begins to turn lightly golden.
Slide in the lemon slices and cook for a few minutes before gently turning them over.
Continue cooking until the slices are coated in a glossy citrus syrup.
Transfer them to baking paper to cool.
Once the tart has chilled and set, arrange the candied lemon slices across the top for a beautiful finishing touch.
Cozy Tips & Serving Ideas
Chill before serving
Refrigerating the tart helps the filling firm up into a silky texture that slices beautifully.
Balance the sweetness
If you prefer a slightly lighter dessert, reduce the sugar in the filling by a tablespoon for a more citrus-forward flavor.
Make it gluten-free
Swap the flour in the crust for a high-quality gluten-free baking blend to create a gluten-free friendly version.
Perfect for gatherings
This tart slices cleanly and holds its shape, making it a lovely family gathering dessert or elegant brunch treat.
Serve with fresh berries
Strawberries or raspberries add a fresh contrast that makes each bite feel brighter and more refreshing.
Prep ahead for busy days
Because the tart chills beautifully, it’s an excellent make-ahead dessert for relaxed entertaining or cozy weekend baking.
