Gluten-Free Lemon Pie with Meringue Topping
Bright, tangy gluten-free lemon pie with a crisp rice flour and cornmeal crust, silky sweetened condensed milk filling, and billowy meringue crown. The combination of lemon juice and sweetened condensed milk creates a naturally tart, creamy custard that requires no baking soda or additional thickeners. Serve chilled or at room temperature for dessert gatherings, holiday tables, or when you need an impressive gluten-free showstopper. This version skips traditional wheat flour entirely, making it naturally celiac-friendly while maintaining the nostalgic appeal of a classic American pie.

Tips
For a sturdy meringue that resists weeping, ensure the mixing bowl is completely grease-free and add 1/4 teaspoon cream of tartar when beating the egg whites.
Lemon juice naturally cooks the sweetened condensed milk into a custard without gelatin; don't overbake the filling or it may crack.
Serve pie cold for cleaner slices; meringue is best enjoyed within 24 hours.
Good to Know
Cover and refrigerate up to 3 days. Meringue weeps over time; consume within 24 hours for best texture.
Prepare crust dough and refrigerate up to 2 days. Bake crust and cool, then fill and bake up to 1 day ahead. Top with meringue just before serving.
Serve chilled or at cool room temperature. A small dollop of whipped cream or fresh lemon zest adds finish. Pairs with herbal tea or after-dinner coffee.
Common Mistakes
Underbake the crust before adding filling to avoid soggy bottoms; parbake until visibly set and lightly browned
Overbake the filling; it will crack and separate when overcooled
Beat meringue in a warm or greasy bowl; any fat or moisture prevents stiff peaks and causes weeping
Add meringue to hot pie; let filling cool fully first to prevent curdling egg whites

FAQ
Can I make this without a tart pan?
Yes, use a standard 9-inch pie pan or deep 8-inch cake pan. Adjust baking time by 2-3 minutes since pan shape changes heat distribution. Press dough gently and prick thoroughly to prevent puffing.
What if my meringue collapses or weeps?
Weeping occurs when meringue sits too long or oven temperature drops during bake. Add 1/4 teaspoon cream of tartar to egg whites before beating. Bake meringue at 325F for 12-15 minutes until lightly golden, then cool slowly in the oven with door cracked.
How long does the finished pie keep, and can I freeze it?
Refrigerate covered up to 3 days; meringue texture degrades after 24 hours. Freezing is not recommended due to meringue breakdown. Freeze unfilled crust or filling separately; thaw and assemble fresh for best results.
