What is a Classic Key Lime Pie?
Key lime pie is a traditional American dessert characterized by its bright citrus flavor and creamy texture. The main components are:
- Graham cracker crust: Buttery and crunchy, it supports the filling without overpowering it.
- Key lime filling: Made with egg yolks, sweetened condensed milk, key lime juice, and lime zest, resulting in a silky, tart custard.
- Whipped cream topping: Softly whipped cream, sometimes accented with zest, is piled on before serving.
Key limes, smaller and more aromatic than Persian limes, give the pie its distinctive floral tartness. However, due to their scarcity, many recipes use bottled key lime juice.

Classic Key Lime Pie: Ingredients and Recipe
For the Crust
- 12 full sheets graham crackers
- 2 tablespoons granulated sugar
- 6 tablespoons salted butter, melted
For the Filling
- 2 large egg yolks
- 1 (14-ounce) can sweetened condensed milk
- 1/2 cup bottled Key lime juice
- 1 tablespoon grated lime zest (about 2 limes), plus more for garnish
For the Topping
- 1 cup heavy cream
- 2 tablespoons powdered sugar
Step-By-Step Directions
- Prep the oven and pie plate: Preheat the oven to 350°F. Use a 9-inch pie dish.
- Make the crust:
- Pulverize the graham crackers and sugar in a food processor until finely ground.
- Add melted butter; pulse until the crumbs are evenly coated and clump slightly when pressed.
- Press mixture firmly into the bottom and sides of the pie plate. Bake for about 10 minutes, until just set and golden. Cool slightly, about 10 minutes.
- Mix the filling:
- In a medium bowl, whisk egg yolks, sweetened condensed milk, lime juice, and lime zest until fully combined and silky.
- Pour the filling into the cooled crust, smoothing the top.
- Bake the pie:
- Bake until the center is set but slightly jiggly (about 15 minutes).
- If the filling appears liquid-y, bake for a few more minutes—but avoid overbaking.
- Let cool at room temperature for 30 minutes, then refrigerate at least 1 hour until fully set.
- Prepare whipped cream:
- Just before serving, whip heavy cream with powdered sugar until soft peaks form.
- Spread or pipe the whipped cream decoratively on the chilled pie. Garnish with more lime zest.
Expert Tips and Tricks for Key Lime Pie Success
- Graham cracker crust: Press the crumbs firmly for a solid crust that won’t crack or crumble when slicing.
- Juicing limes: If using fresh key limes, roll them on the counter before cutting to maximize juice.
- Chill time: Allow at least an hour in the fridge, but pie texture is best if chilled overnight.
- Oven temperature: Bake in the lower third of your oven for even cooking.
- Do not overbake: The filling should wobble slightly in the center; it will finish setting as it cools.
- Make ahead: You can bake and chill the pie a day in advance. Top with cream just before serving.
Ingredient Substitutions and Variations
- No key limes? Regular (Persian) limes work well; flavor will be slightly different but delicious.
- Bottled vs. fresh juice: Bottled key lime juice is common and convenient. If limes are scarce, this is a perfect substitute.
- Dairy-free option: Substitute coconut cream for heavy cream and use a vegan condensed milk.
- Crust alternatives: Try vanilla wafers, digestive biscuits, or gingersnaps for a different flavor profile.

Frequently Asked Questions About Key Lime Pie
How can I tell when key lime pie is done baking?
The filling should be set at the edges and jiggle slightly in the center when you gently shake the pie plate. It should not slosh or appear liquid. The pie will firm up further as it cools and chills.
How long can key lime pie be stored?
When tightly covered, key lime pie keeps well in the refrigerator for up to 5 days. For best flavor and texture, wait to add whipped cream topping until just before serving.
Can I use regular limes instead of key limes?
Yes, Persian limes (the most common supermarket variety) can be substituted. The pie will taste slightly less floral but will be just as refreshing and delicious.
Is bottled key lime juice an acceptable substitute for fresh?
Absolutely. Key limes are often difficult to find outside of certain regions. Most classic recipes—including this one—use bottled juice for convenience and consistency.
How do I make the filling richer?
You can add another egg yolk for a denser custard or increase the lime zest for even more citrus flavor.

Key Lime Pie Success Stories & Troubleshooting
- Crust too loose? Be sure to firmly pack the crumbs, and avoid over-measuring the butter.
- Runny filling? Ensure the pie is baked long enough to just set, and chill thoroughly—at least an hour, preferably overnight.
- Cracking? Overbaking will cause cracks; remove from the oven as soon as the edges are set but the center wiggles.
Tips for a Beautiful Key Lime Pie Presentation
- Pipe whipped cream rosettes around the edges or over the top for a bakery-style finish.
- Sprinkle lime zest on top of whipped cream for a pop of green color and added aroma.
- Garnish with paper-thin lime slices or candied lime peel if desired.
Alternative Recipe Variation: No-Bake Key Lime Pie
Prefer to skip the oven? Here’s a simple no-bake version:
- Crust: Freeze the graham cracker crust for 20 minutes instead of baking it.
- Filling: Whip 3/4 cup heavy cream to stiff peaks, fold into a mixture of 1 (14-oz) can sweetened condensed milk, 12 oz. softened cream cheese, 2 tsp lime zest, and 1/2 cup key lime juice. Blend thoroughly, transfer to crust, and refrigerate at least 12 hours until firm.
- Garnish: Top with more whipped cream and lime zest to serve.
Frequently Asked Questions (FAQs)
Q: What’s the difference between key lime pie and regular lime pie?
A: Key lime pie uses the smaller, more floral and tart key limes, while regular lime pie uses Persian limes. Both are delicious; the key lime version is a touch more aromatic and tangy.
Q: Can I make key lime pie in advance?
A: Yes. You can prepare the pie (minus the whipped cream) and refrigerate it up to two days before serving. Add whipped cream just before slicing to keep it fresh.
Q: Why is my pie filling runny?
A: Either it wasn’t baked quite long enough, or it hasn’t been thoroughly chilled. Give it extra fridge time, and next bake until the edges are set and the center jiggles gently, not sloshes.
Q: How do I zest a lime?
A: Use a microplane or the fine side of a box grater to remove the colored peel only, avoiding the bitter white pith underneath.
