How to make the best Key lime pie
This yummy pie is usually made with a Graham cracker crust, and our version includes a stove-top style filling that includes egg yolks, condensed milk, and fresh Key lime juice – for a great tangy flavor.
Did you know that Key lime pie is the official state pie of Florida? So the next time you are visiting, be sure to order up this perfect dessert for your whole family to enjoy. 🙂
It is possible to use a convection oven, but I wanted to see if I could create a Key lime pie filling the same way I make my lemon meringue pie – on the stove top.
Tips
- The ingredients for this recipe are similar to my lemon pie recipe, however, instead of using cornstarch as a thickener – we use sweetened condensed milk. It’s the combination of this and the lime juice that causes the filling to thicken nicely.
- Mix the sweetened condensed milk and egg yolks first until they are really creamy, then gradually add the Key lime juice.
- Cook the filling on medium to low heat and stir constantly so it doesn’t burn.
- Double the recipe and enjoy one pie now and freeze the other!
FAQS
What’s the difference between Key limes and Persian limes?
It seems to be more about color and size than taste, although some will say that Key limes are more tart.
According to Southern Living: “Limes grown in the Florida Keys tend to be small with a distinctive lime flavor that is tart, but not too acidic with a very distinct aroma. Grocery store limes, generally speaking, are Persian limes, which are larger and tarter than their Florida cousins.”
Does lime juice thicken condensed milk?
Yes, it’s the combination of the two ingredients that thickens your Key lime pie filling.
How do you thicken Key lime pie?
Using a wire whisk, or the whisk attachment on your stand mixer, keep stirring the sweetened condensed milk and egg yolks in a saucepan over medium to low heat while gradually adding the lime juice. Your filling mixture should slowly thicken.
Why did my Key lime filling curdle?
Using whole fresh milk instead of sweetened condensed milk will cause the filling to curdle.
Should I use fresh Key limes or bottled Key lime juice?
It’s really up to you. I’ve used both and don’t really see a difference, but it’s also what’s available in your local grocery stores. Typically you can find Key limes in the produce section, and you want to use fresh Key lime zest for the whipped topping.
How to serve Key lime pie
Always use a sharp knife to cut your Key lime pie into slices.
You can add a couple of lime slices as a garnish.
How to store pie
Once cool, store your pie in an airtight container, or use plastic wrap.
In a refrigerator, your pie should last about three days.
Key lime pies freeze really well for about two months.
Recipe variations
If you’re looking to mix things up a bit, you can change the topping.
We use whipped cream, but others have had success with a meringue topping.
We give you instructions to make your own Graham cracker crust, which is easy to do, but you can also use a ready made pie crust.
If you can’t find bottled Key lime juice or even Key limes, you can use regular limes. Make sure to add plenty of sugar as they tend to be more tart.

Equipment
Ingredients
- 1 1/2 cups graham cracker crumbs
- 6 tbsp unsalted butter
- 1/4 cup white sugar
- 4 large eggs - room temperature
- 1 14 oz can sweetened condensed milk
- 1/3 cup key lime juice
- 2 cups heavy cream - whipping cream
- 2 tbsp key lime zest
Instructions
Graham cracker crust:
- Put the graham crackers in a zip lock bag and use a rolling pin to crush them. Or if you have a food processor crush them in seconds!
- Mix the melted butter, sugar and graham cracker crumbs together
- Spray your pie plate with Pam Baking Spray
- Press the graham cracker crumb mixture into the pie plate and bake at 350F for 8 minutes
- Remove from oven and let it cool on a wire rack
To make the stove top key lime pie filling:
- Separate the eggs into a medium bowl, (TIP: put the egg whites in the freezer!)
- Beat the egg yolks in a large saucepan until thick with medium speed on your mixer.
- Stir in the condensed milk and key lime juice
- Cook on the stove on medium-low, stirring constantly until the mixture starts to thicken. Don’t leave it or it will stick to the pan and we don’t want that to happen!
- Once the filling has thickened, remove from heat and let it cool just a bit. Pour it into the graham cracker crust pie shell and set aside to cool.
- Garnish with Whipped Heavy Cream, Lime Zest and thin slices of fresh lime. This is the very best key lime pie you will ever make!
