Slice-And-Bake Lemon Shortbread: A Sunshine-Filled Treat

The scent of lemon always transports me back to my grandmother’s sun-drenched kitchen. She had a knack for transforming simple ingredients into edible sunshine, and her lemon shortbread was a particular favorite. I remember standing on a stool, eager to help (mostly eager to sample!), as she carefully measured flour and zest, the air thick with anticipation. Even now, decades later, that bright, citrusy aroma is a pure, unadulterated dose of childhood joy. These slice-and-bake cookies are a simple way to recreate those memories, and hopefully create some new ones for you, too.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 12-15 minutes
• Total Time: 3-4 hours 15 minutes (includes chilling time)
• Yields: 36 cookies
• Serves: 36
• Dietary Type: Vegetarian

Ingredients

• 3 cups all-purpose flour
• 1/4 teaspoon kosher salt
• 1 cup unsalted butter, at room temperature
• 3/4 cup granulated sugar
• 1 teaspoon finely grated lemon zest
• 1 teaspoon pure vanilla extract
• Coarse sugar or turbinado sugar, for sprinkling

Equipment Needed

• Medium bowl
• Electric mixer
• Parchment paper
• Ruler or metal spatula (optional)
• Baking sheets
• Wire racks

Instructions

1. In a medium bowl, whisk together the flour and salt. This ensures the salt is evenly distributed throughout the dough, enhancing the overall flavor profile.
2. Using an electric mixer, beat the butter, granulated sugar, lemon zest, and vanilla on medium speed until fluffy, about 2 to 3 minutes. This creaming process incorporates air into the butter and sugar, resulting in a tender shortbread. Don’t rush this step! Make sure the butter is truly at room temperature for the best results. If the butter is too cold, it won’t cream properly.
3. Reduce the mixer speed to low and gradually add the flour mixture, mixing until just combined (do not overmix). Overmixing develops the gluten in the flour, resulting in a tough shortbread. The goal is to incorporate the flour until just moistened. Stop as soon as everything is combined.
4. On a piece of parchment paper, form the dough into a rectangular block, 12 by 2 by 1 inches (use a ruler or metal spatula to square off the sides). This rectangular shape will make slicing uniform cookies much easier later on. The parchment paper makes it simple to wrap and unwrap.
5. Wrap the dough in the parchment paper and refrigerate until firm, about 3 to 4 hours. This chilling period is crucial. It allows the butter to solidify, preventing the cookies from spreading too much in the oven, and it also makes the dough easier to slice. If you’re short on time, you can place it in the freezer for about an hour.
6. Heat the oven to 350°F (175°C). Make sure your oven is properly preheated for even baking. An oven thermometer can be helpful to ensure accurate temperature.
7. Cut the chilled dough into ⅓ inch-thick slices and place them on baking sheets, spaced 1 inch apart. Use a sharp knife to slice the dough cleanly. If the dough starts to soften too much during slicing, return it to the refrigerator for a few minutes. The spacing is important to allow for proper air circulation and even baking.
8. Sprinkle the sliced cookies with coarse sugar or turbinado sugar. This adds a delightful crunch and sparkle to the finished cookies. Gently press the sugar into the dough so that it adheres well.
9. Bake, rotating the baking sheets halfway through, until the edges begin to brown, 12 to 15 minutes. Rotating the baking sheets ensures even baking, especially if your oven has hot spots. Keep a close eye on the cookies, as baking times can vary depending on your oven. The cookies are done when the edges are lightly golden brown.
10. Cool slightly on the baking sheets, then transfer to wire racks to cool completely. Allowing the cookies to cool slightly on the baking sheets helps them to firm up before transferring them to the wire racks. Cooling completely on wire racks prevents them from becoming soggy.
11. Store the cookies in an airtight container at room temperature for up to 7 days. To keep them fresh for longer, store them in the freezer.

Expert Tips & Tricks

• Zest with Precision: When zesting the lemon, avoid the white pith underneath the yellow skin, as it can be bitter. Use a microplane grater for the finest zest.
• Don’t Overwork the Dough: Overmixing the dough will result in tough cookies. Mix only until the ingredients are just combined.
• Chill Time is Key: The chilling time is essential for preventing the cookies from spreading too much during baking. Don’t skip this step!
• Freeze for Future Baking: You can freeze the dough log for up to 2 months. Thaw it in the refrigerator overnight before slicing and baking.
• Baking Paper is Your Friend: Lining the baking sheet with parchment paper not only prevents sticking but also makes cleanup a breeze.

Serving & Storage Suggestions

These lemon shortbread cookies are delicious on their own, but they also pair perfectly with a cup of tea or coffee. They also make a delightful addition to a dessert platter or a thoughtful homemade gift.

To store, keep them in an airtight container at room temperature for up to 7 days. For longer storage, freeze them in a single layer on a baking sheet until solid, then transfer them to a freezer-safe bag or container. They can be stored in the freezer for up to 2 months. There’s no need to reheat them; simply thaw them at room temperature for a few minutes before serving.

FAQs (Frequently Asked Questions)

Q: Can I use salted butter instead of unsalted butter?

A: It’s best to use unsalted butter so you can control the amount of salt in the recipe. If you only have salted butter, omit the ¼ teaspoon of kosher salt in the recipe.

Q: Why are my cookies spreading too much?

A: This is usually due to the butter being too warm. Make sure the butter is at room temperature but not melted. Also, ensure you chill the dough for the recommended amount of time.

Q: Can I make the dough ahead of time?

A: Yes, the dough can be made ahead of time and stored in the refrigerator for up to 2 days. You can also freeze the dough for up to 2 months.

Q: How do I prevent the cookies from burning on the bottom?

A: Make sure your oven rack is in the center position and use parchment paper on the baking sheet. This will help to distribute the heat evenly and prevent burning.

Q: Can I add more lemon flavor?

A: Yes, you can add up to 2 teaspoons of lemon zest for a more intense lemon flavor. You can also add a teaspoon of lemon extract.
