Light, airy, and bursting with zesty lemon flavor, these Lemon Meringue Cookies have a crisp exterior and melt-in-your-mouth texture. Naturally gluten-free and low in fat, they're perfect for spring, tea parties, or a guilt-free dessert any time.
Preheat oven to 225°F (110°C). Line two baking sheets with parchment paper.
In a clean, grease-free mixing bowl, add egg whites and a pinch of salt. Beat with an electric mixer on medium speed until foamy.
Add cream of tartar and continue beating until soft peaks form.
Gradually add sugar, one tablespoon at a time, beating on high until stiff, glossy peaks form and sugar is dissolved.
Gently fold in lemon zest, lemon extract (or juice), vanilla extract (if using), and a drop of yellow gel food coloring (optional).
Transfer the meringue mixture to a piping bag fitted with a star or round tip. Pipe small mounds or swirls onto prepared baking sheets.
Bake for 1–1.5 hours, or until cookies are dry and lift easily from parchment. Turn off oven, leave door slightly ajar, and let cookies cool inside for 1 hour.
Once completely cool, store cookies in an airtight container at room temperature for up to 5 days.
