This Key Lime Pie has that signature creamy texture and classic sweet-tart flavor everyone loves. Ever since I brought this recipe home from Savannah, it has been the pie my family requests again and again.
Why this Savannah Recipe Works Every Time
I found this recipe in Savannah on a trip with my friend Amie, and I’ve been making it at home for years. It has become a tradition to have it for Thanksgiving and Easter. I’ve learned that these simple details are what make it work every time:
- Whipping the egg yolks before adding the other ingredients ensures a light, creamy filling.
- The sweet and tart ratio between the sweetened condensed milk and key lime juice is spot on.
- A short bake time keeps the filling smooth without drying it out or causing cracks.
- Chilling the pie for a minimum of 3 hours is ideal for the flavors to blend and easy slicing.

Key Lime Pie Ingredients
- Sweetened condensed milk gives the filling its silky texture and balances the tartness of the key lime juice.
- Egg yolks help the filling bake up smooth and creamy so it holds its shape once it’s chilled. Save the egg whites for a meringue topping or another recipe.
- Key lime juice is what really shines in this recipe. Fresh, ripe key limes are best, but sometimes hard to find. I’ve found Nellie & Joe’s Famous Key West Lime Juice is a great substitute if I can’t find key limes. I often use it as an addition to the key lime juice I can squeeze out of the key limes, since they are pretty small and sometimes not juicy enough.
- A graham cracker crust adds buttery crunch and holds the creamy filling well. I sometimes make the crust using Biscoff cookies instead of graham crackers. I love the flavor and extra crunch it gives. If you’re short on time, a store-bought graham cracker crust works well.
- Optional topping ideas: I like to decorate the top of my pie with homemade whipped cream and key lime slices. You can also use the separated egg whites to make a meringue topping like in this Lemon Meringue Pie.
How to Make Key Lime Pie
- Prepare the crust: Combine crust ingredients and press them evenly into a pie plate. Use a measuring cup to press the crumbs down firmly. Bake at 375 for 5 minutes and cool.
- Zest and juice key limes: Zest key limes to get 2 teaspoons, the juice key limes to fill a ½ cup measuring cup. If you can’t get a full ½ cup, use Key West Lime Juice to fill the remaining ½ cup.
- Prepare pie filling: Whisk or blend egg yolks until they are thick and turn a light yellow color. Slowly pour in the sweetened condensed milk into the yolks while continuing to mix.
- Gradually add the key lime juice and zest. Blend well.
- Fill the crust: Pour the filling into the prepared graham cracker crust.
- Bake: Place in the oven and bake for 15 minutes. Cool to room temperature then chill for at least 3 hours before serving.
- Garnish: Decorate with whipped cream and key lime slices (optional).
- Slice, serve, and enjoy!
Frequently Asked Questions
If your filling seems too soft, it likely needs more chill time. I’ve found that at least 3 hours in the refrigerator is the sweet spot, though overnight is even better. Make sure the filling bakes until it is set with only the slightest jiggle in the center, if at all.
If key limes aren’t available, Nellie and Joe’s Key Lime Juice is the next best option. Regular limes can be used as a last resort, it does change the taste. However, many of our readers have commented that they’ve used limes and the pie turns out great.
You can do either. Chilling the crust for an hour will set it, but baking it gives it a slightly toasted, firmer texture.
The baking time of 15 minutes is pretty accurate, but elevation and ovens do vary. The filling should look set and only slightly jiggly in the very center of the pie. The top of the pie should not be browned at all.
Yes, this is a great make ahead dessert. You can prepare the pie a day in advance and keep it refrigerated until ready to serve. It actually tastes best after chilling for several hours.
You can. Bake and cool the pie completely. Wrap it tightly in plastic wrap and freeze for up to 2 months. Thaw it in the refrigerator overnight before serving. Wait to add whipped topping until after the pie has thawed and you are ready to serve.

Very easy and great taste!Will make again.
Excellent results! First time I’ve ever made a Key Lime pie – no need to look up other recipes now!
Thanks!
A quick and easy pie
The family loves it
So simple to make. I had to use just a little of the key lime juice. Zested and juiced the key limes.
A great pie to make when you don’t have a ton of time, it’s easy to put together.
Thank you so much for this recipe! It tasted so good! The citrus was not overwhelming 🥰 and everyone at church loved it haha! Thank you again!☺️
Here is some good news for you by the way!
For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures; and that he was buried, and that he rose again the third day according to the scriptures:”
1 Corinthians 15:3-4 KJV
“and brought them out, and said, Sirs, what must I do to be saved? And they said, Believe on the Lord Jesus Christ, and thou shalt be saved, and thy house.”
Acts 16:30-31 KJV❤️❤️
The pie has a wonderful flavor, but why does the filling barley go up to half of the crust?
I used a foil 9 inch pie pan.
Oh that is odd! How deep was the crust?
Most easy and very tasty pie
Normal pie plate.
Made key lime pie for the first time using this recipe and it is a success. The recipe is simple, but the flavor of the pie is so good. I used fresh juice and didn’t use premade juice – maybe that also makes a difference. This recipe is a keeper!
I man going to make this recipe however I don’t know how much juice is if I’m using the key lime juice in the bottle, not actual limes. Can you give a measurement if ounces?
You get about 2 tablespoons of juice from each key lime, so you’ll need about 12 tablespoons or 6 ounces. Hope this helps!
Newbie question: I’m assuming it’s 14oz volume as opposed to weight of condensed milk? They come in 14oz (net weight) cans so I think I didn’t catch that and therefor didn’t use enough, my novice mistake! Such is life with the Imperial System.. lol Thanks!
Our recipe uses 1 14oz can of sweetened condensed milk. Hope that helps! Sorry for the confusion.
I am having the same problem the batteries done. I put it into the pie shell. There is definitely not enough batter to fill the shell. It only comes like maybe halfway up and I know this doesn’t rise so I’m very disappointing cause I’m gonna feel stupid bringing this to a barbecue tomorrow. When looks like it’s half made other people must have this problem. Yes, I used a 9 inch pie plate and crust.
Some pie plates are deeper than others – we have been making this recipe for years in a 9 inch pie dish and it always fills the whole dish.
This is my first time making key lime pie. It most definitely won’t be my last. Of course like any good cook I had nibbles. My grandson say’s it’s one of his favorites. He juiced the limes and zested them for me. Will be making a fresh pot of coffee to serve with it tonight. So good
Delicious! Can I substitute the Graham cracker crust with a Nilla wafer crust or r maybe combine the 2? Wanted to try a different spin and I am craving Nilla wafers.
Sure!
5 stars because it’s key lime.
My question is I’d like to juice 9 key limes instead of 6.(for that extra kick).
What do I need to change the recipe to keep the filling thick?
Thanks in advance,. Frostproof,FL.
The whipped egg yolks are what gives the pie structure, so I would start there!
Hey thanks for the fast reply.
Since I plan on 50% more juice, I’ll go with 50% more yolks.
We’ll start there. Gonna do one today.
I’ll be sure to let you know how it turns out.
Step one is a little unclear. You zest the limes and juice them- but the next step says to cut the zested limes in half and juice them. Is that an accidental repeat?
Oh, yes the juicing is mentioned twice. Thanks for catching that! I will change it!
Salted butter or Unsalted butter? I searched the comments and could not find this question.
Thank you.
Either one works great.
In the oven now but it doesn’t look like it made enough to fill the pie crust. Is it going to rise?
It doesn’t rise very much. What size pie crust did you use?
I used a 9inch, and there is extra room, for the whipped cream!
Hi! I want to try Key Lime Pie!
But if i get the Lime jus in a bottle will it be the same taste?
Or shoudl i get Bottle of Key lime jus on Anazone? And also amouch key lime jus do we need to use 1/4 cup?
Thxs:)
If you can’t find key limes or key lime juice, you can substitute common limes. You can swap out 6 fresh key limes for 1 large regular lime. As far as the juice goes, you can swap it out at a 1:1 ratio (¼ cup key lime juice for ¼ cup regular lime juice).
Really good recipe! I enjoyed making the Key Lime pie.
Can you just use the key lime juice and no limes and will it still taste good?
Does this freeze well?
Yes! It freezes great!
So easy to make. Directions are clear and simple to read. A real down home and delicious pie.
