Ingredient Notes

• Vanilla wafers: These give the crust that classic retro flavor and soft crunch once chilled. Crush them in a zip-top bag with a rolling pin or use a food processor.
• Butter: Melted butter helps bind the crust and adds richness to balance the bright lemon filling.
• Lemon juice: Fresh lemon juice gives the pie its signature sunshine flavor. Bottled works in a pinch, but fresh is best.
• Lemon zest: Adds extra citrus aroma and makes the flavor pop.
• Unflavored gelatin: This is what helps the chiffon filling set up light and fluffy instead of loose. Be sure it fully dissolves.
• Eggs: Separate them carefully so the whites whip properly for that airy texture.
• Whipped cream: Store-bought keeps it simple, but homemade works great too if you want a richer finish.

Quick Prep Notes

Do I have to cook the filling?
Yes. The egg yolks, sugar, and lemon juice need to be gently cooked so the filling thickens and the gelatin dissolves properly.

How long does the pie need to chill?
Plan for at least 4 hours in the refrigerator so the chiffon filling sets fully and slices clean.

Can I make this ahead of time?
Absolutely. This pie is perfect for making the night before since the flavor and texture improve as it chills.

Ingredients

Scale 1x2x3x

Vanilla Wafer Crust

• 2 cups crushed vanilla wafers
• ⅓ cup melted butter

Lemon Chiffon Filling

• 1 envelope unflavored gelatin
• ¼ cup cold water
• ¾ cup sugar
• ⅓ cup fresh lemon juice
• 1 tablespoon lemon zest
• 3 eggs, separated
• 1 cup whipped cream

Instructions

1. Stir the crushed vanilla wafers and melted butter together until everything looks evenly coated. Press the mixture firmly into a pie dish, working it up the sides a bit too. Pop it in the fridge to chill while you make the filling.
2. Sprinkle the gelatin over the cold water and let it sit for about five minutes so it can soften.
3. In a saucepan, whisk together the egg yolks, sugar, lemon juice, and zest. Cook over medium heat, stirring constantly, until the mixture thickens and looks smooth and glossy.
4. Remove the pan from the heat and stir in the softened gelatin until it completely dissolves. Let the mixture cool to room temperature.
5. In a separate bowl, beat the egg whites until stiff peaks form. Gently fold them into the cooled lemon mixture, followed by the whipped cream. Take your time here to keep that light, fluffy texture.
6. Pour the filling into the chilled crust, smooth the top, and refrigerate for at least four hours until fully set.

FAQ

Can I use bottled lemon juice?
Yes, but fresh lemon juice and zest give the brightest flavor and that classic sunshine taste.

Is this pie baked?
Only the crust is pressed and chilled. The filling is cooked on the stovetop and then refrigerated to set.

Can I use Cool Whip instead of whipped cream?
Yes. It works well and keeps the recipe simple.

How do I store leftovers?
Keep the pie covered in the refrigerator for up to 3 days.

Can I freeze lemon chiffon pie?
Freezing isn’t recommended because the texture can become icy and lose its light, fluffy consistency.
