Perfect for gatherings or a quick homemade treat, it slices beautifully and can be served chilled or at room temperature.

Pie Ingredients

1 cup granulated sugar
½ cup unsalted butter, melted
4 large eggs
½ cup all-purpose flour (or Bisquick mix if preferred)
¼ cup fresh lemon juice (about 2 lemons)
1 tablespoon lemon zest
1 ½ cups whole milk
1 teaspoon pure vanilla extract
Pinch of salt
Optional: ½ cup shredded coconut

Instructions

Preheat Oven and Prepare Dish: Preheat your oven to 350°F (175°C). Lightly grease a 9-inch pie dish with butter or nonstick spray to prevent sticking.
Blend Ingredients: In a blender or large mixing bowl with a whisk, combine the sugar, melted butter, eggs, flour (or Bisquick), fresh lemon juice, lemon zest, whole milk, vanilla extract, and a pinch of salt. Blend or whisk until the mixture is smooth and well incorporated.
Pour Mixture into Pie Dish: Transfer the smooth batter into the prepared pie dish. The batter will be quite thin, but this is normal and essential for the pie’s unique layering while baking.
Bake the Pie: Place the pie dish on the center oven rack and bake for 35 to 40 minutes, or until the top is lightly golden and the center is set but may have a slight jiggle. A knife inserted in the center should come out mostly clean.
Cool the Pie: Remove the pie from the oven and let it cool completely on a wire rack. As it cools, the pie will firm up and the signature layers—the crust on the bottom, creamy lemon custard in the middle, and golden top—will become more distinct.
Chill and Serve: For best results, chill the pie in the refrigerator for a few hours before serving to allow it to fully set. Slice and serve chilled or at room temperature. Garnish with whipped cream or lemon slices if desired.

Notes

Use room-temperature eggs for better custard structure.
Fresh lemon juice and zest are essential for bright citrus flavor; bottled lemon juice can be used in a pinch.
The shredded coconut is optional but adds a nice texture and subtle flavor.
If you don’t have Bisquick, substitute with a homemade mix of 1 cup flour, 1 ½ teaspoons baking powder, ½ teaspoon salt, and 1 tablespoon cold butter.
Store leftovers covered in the refrigerator for up to 4 days; avoid freezing as it can alter texture.
This pie gets better after chilling, making it ideal for make-ahead preparation.
For a different twist, substitute lime juice and zest in place of lemon for a tropical flavor.
