Can I make Key Lime Pie without eggs?

Yes! You can create an egg-free version by using the acid in the lime juice to set the sweetened condensed milk. Simply mix the condensed milk with lime juice and let it thicken naturally. The texture will be slightly different but still delicious, and this version doesn't require baking.

How do I know when my Key Lime Pie is properly set?

A properly set Key Lime Pie will have a filling that's firm around the edges but still slightly jiggly in the center when you gently shake the pan. After chilling for at least 4 hours, the pie should slice cleanly without the filling running, and you'll have that perfect creamy texture that makes this dessert so beloved.

What's the difference between key limes and regular limes in this recipe?

Key limes are smaller, more aromatic, and have a distinctive tart flavor with floral notes that regular Persian limes lack. While you can substitute regular lime juice, you'll need about ⅓ cup instead of ½ cup since Persian limes are less acidic. The authentic Key Lime Pie flavor comes specifically from those tiny yellow key limes, which is why many bakers insist on using only the real thing.

Instructions

Prepare the Graham Cracker Crust

Preheat oven to 350°F (175°C).
In a medium bowl, mix graham cracker crumbs, sugar, salt, and melted butter until the mixture resembles wet sand.
Press firmly into the bottom and sides of a 9-inch pie pan, using a measuring cup to smooth and compact.
Bake for 10–12 minutes until lightly golden. Remove and let cool completely.

2. Make the Key Lime Filling

In a large bowl, whisk egg yolks until smooth.
Gradually whisk in sweetened condensed milk until fully combined.
Add key lime juice, zest, and vanilla extract, whisking until smooth and slightly thickened.
Pour filling into the cooled crust and smooth the top.

3. Bake and Chill

Bake for 12–15 minutes, until the center is just set with a slight jiggle.
Cool completely at room temperature, then refrigerate for at least 4 hours or overnight.

4. Whipped Cream Topping

Just before serving, whip heavy cream, powdered sugar, and vanilla until soft peaks form.
Spread or pipe over the chilled pie.
