Ingredients for key lime pie recipe
- 1 1/2 cups graham cracker crumbs
- 6 tablespoons unsalted butter, melted
- 2 tablespoons granulated sugar
- 1 (14 oz) can sweetened condensed milk
- 4 large egg yolks
- 1/2 cup freshly squeezed key lime juice
- 1 tablespoon lime zest
- 1 teaspoon vanilla extract (alcohol-free)
- 1/4 teaspoon salt
- 1 cup whipped cream

If you can’t find fresh key limes, regular Persian limes work in a pinch, though the flavor won’t be quite as sharp. I’ve also made this with bottled key lime juice when I’m in a rush, and honestly it still tastes great—just not as bright. Trust me on the fresh juice though—it’s worth the extra squeeze.
Step-by-step instructions
1. Preheat your oven to 350°F. Mix graham cracker crumbs, melted butter, and sugar in a bowl until it looks like wet sand. Press this mixture firmly into a 9-inch pie dish, covering the bottom and sides evenly. Bake for 5 minutes until it just starts to smell nutty and toasted. Remove and let cool while you make the filling.
2. Whisk together the sweetened condensed milk, egg yolks, key lime juice, lime zest, vanilla extract, and salt in a medium bowl. Stir until everything combines smoothly—this should take about 2 minutes of steady whisking. The filling will look pale and thick, which is exactly what you want.
3. Pour the filling into your cooled crust and spread it evenly. You’ll hear a little sizzle when it hits the warm crust—don’t panic, that’s totally normal. Bake for 12 to 15 minutes until the edges are set but the center still jiggles just slightly when you shake the pan.
4. Remove the pie from the oven and let it cool completely on the counter. This takes about 30 minutes and is super important—don’t skip this step or your pie won’t set properly. Once it’s cooled, transfer it to the refrigerator.
5. Chill the pie for at least 4 hours, though overnight is even better if you can wait. The filling continues to set as it cools, getting creamier and more custard-like. I always make mine the day before serving so I’m not stressed about timing.
6. When your kitchen smells like fresh citrus and you’re ready to serve, whip together the heavy cream and powdered sugar until soft peaks form. Don’t overbeat it or you’ll end up with butter, which I learned the hard way. The whipped cream should be fluffy and just barely holding its shape.
7. Slice the pie with a sharp knife dipped in hot water—this prevents the filling from sticking to the blade. Wipe the knife clean between each cut for neat slices. Top each slice with a dollop of whipped cream and maybe a tiny pinch of lime zest if you’re feeling fancy.

Frequently asked questions
How long does key lime pie recipe last in the fridge?
Your pie stays fresh for up to three days when stored properly in an airtight container. Keep it on the coldest shelf, not the door where temperature fluctuates. After day three, the crust gets soggy and the filling starts to separate slightly.
Can I use regular limes instead of key limes?
Yes, regular Persian limes work fine if you can’t find key limes. You’ll need about six to eight regular limes to get 1/2 cup of juice. The flavor won’t be quite as intense or distinctive, but the pie will still taste delicious and tangy.
Can I make this pie without eggs?
You can try using pasteurized eggs or egg substitute, but the texture changes significantly. The eggs help create that creamy custard consistency that makes this dessert special. Honestly, I wouldn’t recommend skipping them entirely.
Is this a no-bake pie recipe?
No, this tangy pie requires baking both the crust and the filling. The baking time is short though—only 20 minutes total in the oven. The majority of the time is spent chilling, which is completely hands-off.
