Ingredients You’ll Need
Let’s break down the simple ingredients that come together to create this delicious Lemon Icebox Pie.
For the Graham Cracker Crust:
- 1 ½ cups graham cracker crumbs (about 12 full crackers)
- ⅓ cup granulated sugar
- 6 tablespoons unsalted butter, melted
For the Lemon Filling:
- 2 cans (14 ounces each) sweetened condensed milk
- ¾ cup fresh lemon juice (about 4–5 lemons)
- 1 tablespoon lemon zest (zest from 1–2 lemons)
- 4 large egg yolks
Optional Whipped Topping:
- 1 cup heavy whipping cream
- 2 tablespoons powdered sugar
- ½ teaspoon vanilla extract
How to Make Lemon Icebox Pie (Step-by-Step)
Step 1: Prepare the Crust
Start by preheating your oven to 350°F (if you want to bake the crust for extra crunch and flavor). In a medium mixing bowl, combine the graham cracker crumbs and sugar. Stir in the melted butter and mix until the texture resembles wet sand.
Press the mixture firmly into the bottom and up the sides of a 9-inch pie dish. You can use the bottom of a measuring cup to help press it evenly.
- To bake: Place the crust in the oven for about 8 minutes, then let it cool completely.
- No-bake option: You can skip baking and just chill the crust in the refrigerator while you prepare the filling.
Step 2: Make the Lemon Filling
In a large bowl, whisk the egg yolks until smooth and slightly thickened. Add the sweetened condensed milk, lemon juice, and lemon zest. Mix until everything is well combined and creamy.
Tip: For the best lemon flavor, use fresh lemon juice rather than bottled. Fresh juice gives the filling a brighter, cleaner taste.
Step 3: Pour and Chill
Pour the lemon filling into the prepared crust and smooth out the top with a spatula. Place the pie in the refrigerator and chill for at least 4 hours, or preferably overnight. This allows the filling to firm up to the perfect consistency.
If you’re short on time, you can pop it in the freezer for about 1–2 hours, but be careful not to freeze it solid unless you’re intentionally serving it frozen.
Step 4: Make the Whipped Cream Topping (Optional)
Just before serving, beat the heavy cream, powdered sugar, and vanilla extract in a mixing bowl using an electric mixer until soft peaks form. Spoon or pipe the whipped cream over the chilled pie.
For a clean presentation, add whipped cream only to the outer edge of the pie or dollop individual slices as you serve.
Lemon Icebox Pie Tips & Tricks
Use Room Temperature Ingredients
Let your egg yolks and sweetened condensed milk sit out for a few minutes before mixing. Room temperature ingredients combine more smoothly and create a silkier texture.
Don’t Skip the Zest
The zest is where the intense lemon aroma lives. It deepens the lemon flavor and gives the pie a more complex citrusy kick. Use a microplane for the best results.
Want a Thicker Filling?
You can add 2 ounces of softened cream cheese to the filling mixture for a thicker, slightly tangier version. It will also cut the sweetness a bit more.
How to Get the Perfect Slices
For clean slices, dip a sharp knife in warm water and wipe it between each cut. This prevents the creamy filling from sticking and gives you picture-perfect servings.
Variations and Ingredient Substitutions
Use Different Citrus
While lemon is the classic, you can easily substitute lime juice for a Key Lime Icebox Pie twist or try a blend of lemon and orange for a more mellow citrus flavor.
Graham Cracker Crust Alternatives
No graham crackers? No problem! Try:
- Vanilla wafers
- Shortbread cookies
- Gingersnaps (for a spiced twist)
Just keep the ratios the same—about 1 ½ cups of crushed crumbs to 6 tablespoons of butter.
Dairy-Free Version
Substitute sweetened condensed coconut milk (found in many grocery stores or online) and use a dairy-free whipped topping to make this pie friendly for non-dairy eaters.
How to Store Lemon Icebox Pie
Lemon Icebox Pie is one of those desserts that actually tastes better after a little chill time. Here’s how to store it:
In the Refrigerator
Cover the pie loosely with plastic wrap or foil. It will keep well in the fridge for up to 5 days. The crust may soften slightly over time, but the flavor remains fantastic.
In the Freezer
Want to make it ahead? Freeze the pie (without whipped cream) for up to 1 month. Wrap it tightly in plastic wrap and then in foil to prevent freezer burn. Thaw overnight in the fridge before serving and add whipped cream just before slicing.
Pro tip: Serve it semi-frozen for a refreshing, ice cream-like texture on hot days.
