Ingredients

(Tip: You'll find the full list of ingredients and measurements in the recipe card below.)

Lemon Filling:
4 large eggs
⅓ cup fresh lemon juice
1 ½ cups granulated sugar
1 tablespoon lemon zest
1 tablespoon orange zest
⅓ cup butter, melted
Powdered sugar, for topping

Shortbread Crust:
2 cups all-purpose flour
½ cup powdered sugar
¾ cup cold butter, cut into cubes

Directions

1. Preheat the oven to 350ºF.

2. In a blender, combine the eggs, lemon juice, granulated sugar, lemon zest, and orange zest. Blend on high until smooth. Add melted butter and blend again until fully incorporated. Set aside.

3. In a food processor, pulse the flour and powdered sugar together to combine. Add the cold cubed butter and continue pulsing until the mixture resembles coarse crumbs or wet sand.

4. Place an 11-inch tart pan on a baking sheet. Pour the crust mixture into the pan and press it evenly and firmly into the bottom and up the sides.

5. Pour the lemon filling into the prepared crust.

6. Bake for 30–35 minutes, or until the center is just barely set.

7. Remove from oven and allow the tart to cool completely.

8. Before serving, dust with powdered sugar and slice.

FAQs

Can I use bottled lemon juice?

Fresh lemon juice is highly recommended for the best flavor, but bottled can work in a pinch.

Do I need a tart pan?

An 11-inch tart pan with a removable bottom is ideal, but a regular pie dish can be used if needed—just watch for doneness.

Can I make the crust without a food processor?

Yes, you can cut the butter into the flour and sugar using a pastry cutter or your fingers until the mixture resembles crumbs.

How do I know when the tart is done baking?

The center should be just set and no longer jiggly. It will continue to firm up as it cools.

Can I use orange juice instead of lemon?

You can, but the tart won’t have the same tangy brightness. Orange juice makes for a sweeter variation.

Can this be made ahead of time?

Absolutely! This tart can be made a day in advance and stored in the fridge.

Why does my filling have bubbles or cracks?

Overbaking or high oven temperature can cause this. Remove the tart as soon as the center is just set.

What can I use instead of powdered sugar for topping?

You can use a light drizzle of white chocolate or whipped cream for a different finish.

Is this tart overly sweet?

No—thanks to the balance of lemon juice and zest, the sweetness is offset by the tartness for a perfect harmony.

Can I double the recipe?

Yes, for a crowd, double the recipe and bake in a larger pan, adjusting baking time as needed.
