Instructions

Step 1: Prepare the Crust

  1. Preheat your oven to 350°F (175°C).
  2. In a food processor, combine the flour and powdered sugar. Pulse a few times to blend.
  3. Add the cold butter cubes and pulse until the mixture looks like fine crumbs and begins to hold together when pressed.
  4. Pour the crumbly dough into an 11-inch tart pan with a removable bottom (place it on a baking sheet for easier handling).
  5. Press the crust mixture evenly into the bottom and up the sides of the pan. Make sure the base is smooth and compact.

Step 2: Make the Lemon Filling

  1. In a blender, combine the eggs, sugar, lemon juice, lemon zest, and orange zest. Blend on high speed until smooth.
  2. Add the melted butter and blend again until completely incorporated and silky.

Step 3: Assemble and Bake

  1. Pour the lemon filling into the prepared crust, spreading it evenly.
  2. Bake for 30–35 minutes, or until the center is almost set but still slightly wobbly when gently shaken.
  3. Remove from the oven and let the tart cool completely on a wire rack.

Step 4: Serve

Once cooled, dust the top generously with powdered sugar. Slice into wedges and serve chilled or at room temperature.


Tips for Perfect Results

  • Use fresh lemons: Bottled lemon juice won’t give the same bright, natural flavor.
  • Chill before serving: The tart slices more cleanly and tastes even better after chilling for at least 1–2 hours.
  • Tart pan safety tip: Always place your tart pan on a baking sheet before baking — the removable bottom can be tricky to lift on its own.
  • Texture tip: The crust may seem crumbly before baking, but this is what creates its signature shortbread texture once cooled.
  • Add flair: For a special touch, garnish each slice with a thin lemon slice, zest curls, or a dollop of whipped cream.

Storage

Store leftovers in the refrigerator, covered, for up to 3 days. For longer storage, wrap tightly and freeze for up to 1 month. Thaw in the refrigerator before serving.
