This Ultimate Classic Lemon Tart recipe features a buttery fully baked tart crust filled with a silky, tangy lemon curd made from fresh lemons, eggs, and butter.

Ingredients

Scale

Crust

  • 1 fully baked tart crust

Lemon Curd Filling

  • 2 large eggs plus 2 egg yolks (or 3 whole eggs)
  • ¾ cup (150 g/5.3 oz) granulated sugar
  • 1 tablespoon lemon zest
  • ½ cup (120 ml) freshly squeezed lemon juice (from 23 lemons)
  • 2 tablespoons heavy cream (optional)
  • ½ cup (1 stick/115 g) unsalted butter, cut into small pieces

Instructions

  1. Prepare the lemon curd mixture: In a medium heatproof mixing bowl, whisk together the eggs, egg yolks, sugar, lemon zest, lemon juice, and heavy cream if using until evenly combined.
  2. Cook over bain-marie: Place the bowl over a saucepan of simmering water (bain-marie) on moderate heat. Whisk the mixture constantly to prevent curdling and cook until thickened. This should take approximately 10 to 20 minutes. The curd is done when it reaches 170°F (75°C), or when it coats the back of a wooden spoon and leaves a clear track when your finger is run through it.
  3. Strain and add butter: Remove the bowl from the heat and immediately strain the curd through a fine mesh sieve to remove any cooked egg bits. Gradually whisk in the butter cubes a few at a time until fully melted and incorporated, creating a smooth and airy texture.
  4. Cool the lemon curd: Allow the lemon curd to cool to room temperature. This helps it set properly and prevents the crust from becoming soggy when filled.
  5. Fill and chill the tart: Pour the cooled lemon curd into the fully baked tart crust, smoothing the top. Refrigerate the tart for at least 4 hours or until thoroughly chilled and set.
  6. Serve: Serve the lemon tart chilled, optionally garnished with fresh berries and whipped cream. Because it is rich, slice into small servings.

Notes

  • Lemon curd can be stored in an airtight container in the refrigerator for up to 1 week.
  • For longer storage, freeze lemon curd for up to 2 months; thaw overnight in the fridge then whisk before use.
  • Use fresh lemons for the best bright, tangy flavor.
  • Constant whisking over bain-marie ensures a smooth and silky texture without curdling.
  • You can omit the heavy cream for a more traditional lemon curd, but it adds a nice richness.
  • Slice small servings as the tart is flavorful and rich.
