This citrus shortbread tart crust is tender, buttery, and ideal for tarts filled with curd or cream. It uses just a few straightforward ingredients and can be mixed by hand. Best of all, you don’t need to roll the dough—simply break it into pieces and press it into your tart pan with your fingers for a rustic, even crust.
Making a homemade tart crust is easier than it looks. With a few simple techniques you’ll get a flaky, melt-in-your-mouth shortbread shell that holds up to wet fillings without being tough or greasy.
Below are seven essential tips I rely on to make a quick, flavorful shortbread tart crust that beats store-bought every time.
1. Use ingredients that pack a lot of flavor
Bold fresh ingredients make a big difference. Fresh citrus juice and zest brighten the crust beautifully. Other impactful options include browned butter, a quality vanilla extract, toasted nuts, or a touch of instant espresso for depth.
2. Let your butter get super soft and creamy
For shortbread I soften butter until it’s very soft—think mayonnaise consistency. This makes the dough easy to mix gently by hand and results in a light, creamy texture rather than a dense, greasy crust.
3. Add a bit of cornstarch to your flour
Replacing part of the flour with cornstarch (or rice flour or potato starch) improves the shortbread’s texture, giving it a tender, melt-in-the-mouth crumb that contrasts nicely with crisp edges.
4. Don’t overwork your dough
Overmixing develops gluten and makes the crust tough. Combine ingredients with a light touch and stop as soon as the dough comes together. Shortbread should be tender and delicate, not chewy.
5. Press your dough into the tart pan instead of rolling it out
This recipe is designed to be pressed into the tart pan. Break the dough into small pieces, distribute them evenly across the bottom, then press up the sides with your fingers and palm. It’s simple, fast, and avoids the need for extra flour or rolling.
6. Chill before baking
Chilling is one of the most important steps. Because shortbread has a high fat content, the crust can slump or shrink when placed into a hot oven unless the fat is well chilled. After pressing the dough into the pan, line it with parchment and weigh it down with pie weights or dry beans. Freeze for 20–30 minutes to firm the dough so it holds its shape in the oven.
7. Par bake it with beans or pie weights
Par-baking with weights prevents the crust from puffing and helps it keep clean corners. Press parchment into the dough, fill with pie weights or dried beans, and bake until the edges are golden and the shell is mostly set. Carefully remove the weights, then return the crust to the oven for a few minutes to ensure the bottom is fully baked.
Bonus tip: For very moist fillings, brush the cooled crust with lightly beaten egg white and return it to the oven briefly. This creates a thin seal that helps prevent sogginess.
The instructions below assume you’ll fill the crust with a separate, already-prepared filling (for example, a curd). If your tart filling also bakes in the shell, par-bake the crust a shorter time so it finishes baking with the filling.
Try this crust with citrus curds like grapefruit or lemon, or with fresh mango curd for a bright, silky tart.
Citrus Shortbread Tart Crust
Ingredients
- 1/3 cup powdered sugar
- 4 ounces unsalted butter, very soft
- 1 cup all-purpose flour
- 1/4 cup cornstarch
- 1/4 teaspoon salt
- 2 tablespoons fresh orange, lemon, and/or grapefruit juice
- 1 tablespoon orange, lemon, and/or grapefruit zest
Instructions
- In a large bowl, cream the softened butter, powdered sugar, and citrus zest until fluffy and well combined.
- Add the flour, cornstarch, and salt. Mix gently until just combined.
- Stir in the fresh citrus juice until the dough comes together.
- Butter a 9-inch tart pan. Break the dough into small pieces and distribute them across the bottom and up the sides of the pan. Use your fingers and palms to press the dough evenly across the base and up to the rim. Take a few minutes to smooth and even it out.
- Place a sheet of parchment over the dough and fill with pie weights or dried beans. Freeze for at least 20 minutes to firm the crust.
- Preheat the oven to 375°F (190°C). Bake the weighted crust until the edges are golden and the shell is mostly set, about 22–27 minutes. Carefully remove the parchment and weights, reduce the oven temperature to 325°F (160°C), and bake another 5–8 minutes until the bottom is fully baked through.
- Allow the crust to cool completely before filling.
