1/2 cup granulated sugar (for the crust): A touch of sweetness enhances the buttery flavor of the shortbread.
1/4 teaspoon salt: Elevates all the flavors, balancing sweetness and tartness.
12 tablespoons salted butter, cold and grated: Cold butter creates a flaky texture in the crust.
1/2 cup sourdough discard: This ingredient adds tanginess to the crust while reducing food waste.
16 ounces cream cheese, softened: A key component for the creamy cheesecake filling.
1/2 cup granulated sugar (for the filling): Adds sweetness to the rich cream cheese.
1/4 cup plain Greek yogurt, room temperature: For creaminess and light tang, but feel free to swap with sour cream.

1/8 teaspoon salt: Just a pinch to fine-tune the flavor balance.

1/2 cup lemon curd: This tart spread is the star topping that completes the bars beautifully.

How to Make Lemon Curd Cheesecake Bars with Sourdough Shortbread Crust

Make the Lemon Curd: In a medium saucepan, whisk together 1 cup granulated sugar, 2 beaten eggs, and 2 tablespoons softened salted butter until smooth. Add in the juice of 6 tablespoons fresh lemon juice and place over low-medium heat. Cook while whisking continuously for about 7–10 minutes, or until thick enough to coat the back of a spoon. Remove from heat and let cool in a heat-safe container before refrigerating until ready to use. You can even prepare this curd 1–2 days in advance.
Prepare the Sourdough Shortbread Crust: Preheat your oven to 350°F (175°C) and line a 9×9-inch baking pan with parchment paper, allowing overhang for easy removal. In a large mixing bowl, whisk together 1 1/2 cups all-purpose flour, 1/2 cup granulated sugar, and 1/4 teaspoon salt. Add in the cold grated 12 tablespoons salted butter, using a pastry cutter or your fingertips to create a crumbly texture. Mix in 1/2 cup sourdough discard until a soft dough forms, then press the dough evenly into the baking pan. Bake for 10–15 minutes or until edges turn lightly golden. Let it cool slightly while you prepare the cheesecake filling.
Make the Cheesecake Filling: Reduce oven temperature to 325°F (163°C). In a large bowl, beat together 16 ounces softened cream cheese and 1/2 cup granulated sugar until smooth and creamy. Mix in 1/4 cup room temperature Greek yogurt, 1 teaspoon vanilla extract, and 1/8 teaspoon salt until fully combined. Beat in the room temperature eggs one at a time, mixing on low speed just until incorporated. Gradually add in 2 tablespoons all-purpose flour, 2 tablespoons fresh lemon juice, and 1 tablespoon lemon zest, mixing until smooth but be careful not to overmix.
Combine and Bake: Pour the cheesecake filling over the partially cooled crust, spreading it evenly. Bake for 40 minutes or until edges are set while the center still has a slight jiggle. Turn off the oven and open its door to let the cheesecake cool down slowly for about an hour. After that, cool on the counter for an additional 30–60 minutes.
Chill and Serve: Once cooled, transfer to the refrigerator and chill for at least 4 hours, ideally overnight. Once set, spread 1/2 cup of cold lemon curd over the top of the cheesecake bars before slicing into squares. Serve chilled and enjoy this delightful treat!

Storing & Reheating

To best store your delicious bars, keep them covered in the refrigerator for up to 5 days. A well-sealed container works best to keep them fresh. If you need to store for longer, consider freezing them for up to 3 months. Wrap each bar individually for easy thawing in the fridge. When ready to enjoy again, simply thaw in the refrigerator overnight. While the flavor remains delightful, the texture may soften, so serve chilled for a refreshing treat.

Chef’s Helpful Tips

Avoid overmixing the cheesecake filling to keep it creamy and avoid cracks.
Ensure your cream cheese is at room temperature for smooth blending—this is key to achieving that velvety texture.
You might prefer to chill them overnight for the best flavor and texture; lemon flavor intensifies with a little waiting!
Adjust the sweetness by using less sugar in the crust if you like a slightly tangier flavor.
Feel free to swap Greek yogurt with full-fat sour cream for a richer filling.

These Lemon Curd Cheesecake Bars are not only a delightful dessert but also a canvas for creativity, inviting you to experiment with flavors and toppings. If you wish to switch things up, consider adding fresh berries or even a layer of whipped cream on top for an added touch.

Recipe FAQs

Can I use store-bought lemon curd?

Absolutely! If you’re in a pinch or short on time, feel free to use store-bought lemon curd for convenience. Just make sure to select a high-quality version for the best flavor.

How do I prevent cracks in my cheesecake?

To avoid cracks, ensure you beat the filling just until combined and don’t overbake. Also, bringing your ingredients to room temperature makes a significant impact. Finally, cooling the bars gradually in the oven with the door slightly ajar helps maintain that smooth, crack-free surface.

Can I make this recipe gluten-free?

Yes, you can easily swap out the all-purpose flour with a gluten-free blend in both the crust and filling. Just ensure the substitute is designed for baking to achieve the best texture.

How long do these bars last?

When properly stored in the refrigerator, these bars can last for up to 5 days. If you wish to keep them longer, wrapping them tightly and placing them in the freezer can prolong their shelf life for up to 3 months.
