Ingredients
For the Crust
- 1 pre-made 8-inch pie crust (or homemade shortcrust pastry)
- 1 egg white, lightly beaten (for sealing the crust, optional)
For the Lemon Filling
- 1 cup granulated sugar
- 2 tablespoons cornstarch
- ¼ teaspoon salt
- 1 cup water
- 3 large egg yolks
- 2 tablespoons unsalted butter
- ⅓ cup fresh lemon juice
- 1 tablespoon lemon zest
- 1 teaspoon vanilla extract
For the Meringue
- 3 large egg whites, room temperature
- ¼ teaspoon cream of tartar
- 6 tablespoons granulated sugar
- ½ teaspoon vanilla extract
Instructions
1. Prepare the Pie Crust
- Preheat the air fryer to 320°F (160°C).
- Press the pie crust into a 7–8 inch air fryer-safe pie pan.
- Prick the bottom with a fork and line with parchment paper and pie weights or dried beans.
- Air fry for 10–12 minutes.
- Remove the weights and parchment. Brush with egg white if using, then air fry for another 3–5 minutes until lightly golden. Let cool.
2. Make the Lemon Filling
- In a saucepan, whisk together the sugar, cornstarch, salt, and water.
- Cook over medium heat, stirring constantly, until thickened.
- In a separate bowl, whisk the egg yolks.
- Slowly whisk a small amount of the hot mixture into the yolks to temper them.
- Return everything to the saucepan and cook for 2 minutes, stirring continuously.
- Remove from heat and stir in the butter, lemon juice, lemon zest, and vanilla.
- Pour the hot filling into the cooled pie crust.
3. Make the Meringue
- Beat the egg whites and cream of tartar until soft peaks form.
- Gradually add the sugar, one tablespoon at a time, beating until stiff, glossy peaks form.
- Beat in the vanilla.
4. Assemble the Pie
- Spread the meringue over the warm lemon filling.
- Make sure the meringue touches the edges of the crust to help prevent shrinking.
- Create decorative peaks using the back of a spoon.
5. Air Fry
- Reduce the air fryer temperature to 300°F (150°C).
- Carefully place the pie into the air fryer basket.
- Air fry for 4–7 minutes, checking frequently, until the meringue is lightly golden.
- If the top browns too quickly, loosely cover it with foil.
6. Cool
- Let the pie cool at room temperature for 1 hour.
- Refrigerate for 3–4 hours before slicing for the cleanest cuts.

Tips
- Use room-temperature egg whites for a more stable, voluminous meringue.
- Air fryers brown quickly, so begin checking the meringue after 4 minutes.
- For best results, serve the pie the same day it is made.
- If your air fryer basket is small, use a 7-inch pie pan for the best fit.
