History

Key lime pie, which originated in the late 1800s in the Florida Keys, reflects the region's culinary traditions and the ingredients readily available at the time.
Early recipes relied on sweetened condensed milk, a necessity due to the lack of refrigeration, making it a popular choice. This no-bake dessert features a filling that thickens through a reaction between lime juice and egg yolks, creating its signature creamy texture.
The crust, made from graham crackers introduced by the National Biscuit Company in 1898, adds a delightful crunch.
In 2006, Florida officially designated key lime pie as its state pie, underscoring its cultural significance and celebrating its rich history, which continues to delight dessert lovers today.
Recipe

Key lime pie is a classic dessert that perfectly balances sweetness and tartness, making it a favorite among many. This pie, with its smooth, creamy filling and buttery graham cracker crust, is a delightful treat for any occasion, whether it's a summer gathering or a holiday celebration. The key to an authentic key lime pie lies in using fresh key lime juice, which imparts a unique flavor that sets it apart from regular lime pies.
As you embark on making this pie, you'll enjoy the simple yet rewarding process that results in a delicious dessert. The combination of sweetened condensed milk and egg yolks creates a rich filling, while the pre-baked graham cracker crust adds a satisfying crunch. Once baked and chilled, the pie is ready to be garnished and served, bringing a taste of the tropics to your table.
Ingredients:
- 1 ½ cups graham cracker crumbs
- ⅓ cup granulated sugar
- ½ cup unsalted butter, melted
- 1 can (14 ounces) sweetened condensed milk
- ½ cup fresh key lime juice
- 4 large egg yolks
- Whipped cream, for garnish
- Lime zest and lime slices, for garnish
To prepare the pie, preheat your oven to 350°F (175°C). In a mixing bowl, combine the graham cracker crumbs, granulated sugar, and melted butter until well blended. Press this mixture firmly into the bottom and up the sides of a 9-inch pie dish. Bake the crust for about 8-10 minutes, or until lightly golden.
In another bowl, whisk together the sweetened condensed milk, key lime juice, and egg yolks until smooth. Pour the filling into the pre-baked crust and bake for an additional 15 minutes, or until the filling is set but still jiggles slightly in the center. Remove the pie from the oven and allow it to cool at room temperature before chilling it in the refrigerator for at least 3 hours.
When making key lime pie, using fresh key lime juice will significantly enhance the flavor; bottled juice lacks the bright, tangy taste of fresh. Make sure to chill the pie thoroughly, as this helps the filling firm up and allows the flavors to develop.
Whipped cream is a classic topping, but feel free to get creative with garnishes like toasted coconut or fresh berries. If you prefer a sweeter pie, you can adjust the amount of sugar in the filling to suit your taste. Enjoy your homemade key lime pie!
Cooking Steps

To make your key lime pie, you'll first prepare the graham cracker mixture for the crust.
Next, combine the fresh lime juice and zest with the other filling ingredients.
Finally, you'll whip the heavy cream until stiff and chill the pie before serving for the best flavor.
Step 1. Prepare Graham Cracker Mixture

Start by combining 1 ½ cups of graham cracker crumbs, ¼ cup of brown sugar, and ½ cup of melted butter in a bowl.
Mix everything thoroughly until the graham cracker mixture is evenly coated with the melted butter and brown sugar.
Next, press this mixture firmly into a 9-inch deep-dish pie pan to create a uniform base.
To enhance the texture, pre-bake the crust in a preheated oven at 350°F (175°C) for about 10 minutes, or until it's lightly browned.
This step helps ensure your crust holds up nicely.
Once done, allow the crust to cool completely.
This is key to preventing a soggy bottom when you add the filling for your delicious Key Lime Pie!
Step 2. Combine Lime Juice and Zest

Zest about 8 to 10 key limes using a microplane or fine grater to capture the aromatic oils from the peel, which will enhance your pie's flavor.
You'll want to obtain about 1 to 2 tablespoons of lime zest while avoiding the bitter white pith beneath the skin.
Next, juice the key limes to yield about ½ cup of fresh lime juice, essential for that characteristic tartness.
In a mixing bowl, combine the lime juice and zest with sweetened condensed milk and egg yolks.
Start whisking until the mixture is smooth and well-blended.
This incorporation of both lime juice and zest creates a balanced flavor profile, contributing to your pie's refreshing taste and vibrant color.
Enjoy the process!
Step 3. Whip Heavy Cream Until Stiff

Chill your heavy cream for the best results; ideally, it should be around 36-40% fat content.
Using a clean mixing bowl and beaters—metal or glass works best—start to whip the heavy cream on medium speed with an electric mixer or whisk.
After about 2-3 minutes, you'll notice soft peaks forming. Gradually add about 2 tablespoons of confectioners' sugar per cup of cream to sweeten and stabilize the whipped cream.
Continue whipping until stiff peaks form, which should take an additional 2-3 minutes.
Be careful not to over-whip, as this can make the cream grainy and lead to butter formation.
You want peaks that hold their shape perfectly for your Key lime pie atop the homemade graham cracker crust.
Step 4. Chill Pie Before Serving

Once you've whipped the heavy cream to stiff peaks, it's time to focus on the pie itself.
After baking your key lime pie, let it cool at room temperature for about 30 minutes. This step enhances its texture and flavors.
Next, chill the pie in the refrigerator for at least 3 hours, or ideally overnight. This ensures the filling sets properly and the flavors meld beautifully. Serving the pie chilled will provide a refreshing contrast to its creamy filling.
When you're ready to serve, slice the pie after it's completely chilled and garnish with a dollop of whipped cream and a sprinkle of lime zest for an appealing presentation.
If you have leftovers, keep the pie covered in the fridge for up to 3 days to maintain freshness.
Step 5. Bake Until Set

Before you bake your key lime pie, preheat your oven to 350°F (175°C).
Pour the prepared key lime filling into your pre-baked graham cracker crust, making sure it's evenly distributed. Bake the pie for about 15 minutes. You want the filling to be nearly set but still slightly jiggly in the center.
Once done, let the pie cool at room temperature for a short while. This cooling step is crucial for enhancing the texture and flavor.
For optimal results, refrigerate the pie for at least 3 hours or overnight. This ensures the filling fully sets.
When you're ready to serve, you'll have a delicious key lime pie that's perfectly chilled and ready to impress your guests!
