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.

Easy and delicious!
This was the 1st key lime pie I ever made and will definitely make this recipe again. Thank you!
Simple to make and very tasty
Ultimately the best key lime pie there ever was. It reminds me of my dear sweet mama’s key lime pie. My God bless you, and thank you.
Have to try this key lime pie. Looks yummy!!!
Mine didn’t set. We ate it with a spoon!
You have to beat the egg yolks for about 5 minutes on high speed. If you didn’t do that it could be why it didn’t set up. I just made it and I looked up how long to beat the egg yolks for them to thicken and turn light yellow. My pie came out fine.
Hi there! Can you clarify – *If key limes are not available, you can still make this pie! Substitute 1 lime in place of the 6 key limes.* Does this mean if you are using a regular lime, we only use one for the entire recipe? Thanks!
Yes that is correct. One regular sized lime replaces 6 key limes.
Key limes are not available locally. But I buy Nellie and Joe’s bottled key lime juice and this pie tastes fabulous. If you cannot find it it’s available at Amazon and Walmart.
How much total juice did you use?
This really is so simple to make and so, so good! Perfect amount of lime. So creamy too!
Tart & tangy is the best combination! Key lime flavor reminds me of spring & I’m so excited it’s here! We will be making this asap!!
Thank you so much for sharing this amazing recipe! Will surely have this again! It’s really easy to make and it tasted so delicious! Highly recommended!
I noticed the ingredient list says ¼ Cup Lime Juice and the directions say ½ Cup lime juice. Which is it? I think that will make a difference…..
Sorry its a little confusing, but you juice the key limes into a 1/2 cup. If they fill up the cup, great! If they don’t then fill the rest up with the key lime juice. Hope this helps!
I love this key lime pie! The perfect tart and tangy and sweet mix that is perfectly balanced. So delicious!
Very good recipe.. Made it today.
I’ve made this multiple times and it is always a hit! Everyone who tries it wants the recipe. I use lime juice only because I can’t get key limes where I live (Newfoundland, Canada) and it’s still wonderful!
Hello,
I’ve tried this twice already. My mixture liquefies when i add the lime juice. I add it slowly while mixing in on low speed just as you described it. Any idea what could be the problem?
Oh shoot! I haven’t had that happen before. It could be that your eggs aren’t whipped enough before adding the next ingredients.
Awesome Recipe..

I have made this super easy key lime pie recipe so many times for friends and family. I always get rave reviews from everyone. Thank you so much for posting this recipe because I am a VIP when I make this for a party. I love all your recipes:)
Hi. If I am using mini graham cracker pie shells (purchased from grocery store) how long should I bake them?
The mini ones? I’m not sure we have never used those ones before. I would say start at 10 minutes and check it every few minutes until the center isn’t jiggly anymore. Hope this helps!
I make a key lime pie that tastes fabulous, but it always falls apart! This pie looks great – before I make it, does it keep a firm consistency so that it does not fall apart?
The consistency is perfect, I’ve never had an issue with it falling apart. I think you will love this one!
My son-in-law is lactose intolerant but loves my pies so I substituted vegan butter for regular butter in the crust and condensed coconut milk in the filling. It turned out great although it did have a very faint coconut flavor which I thought made it even tastier!
Thanks for letting us know how you made this lactose free! I am sure there are many of our readers who will find that extremely helpful. I’m not lactose intolerant and that sounds SO good with the coconut milk. YUM!
Dam good pie cheese family all good here
Can I use just the strict just the Nellie and Joe’s key lime juice and no limes??
That should work!
As a variant, you can whip the whites from the eggs until stiff peaks form and fold them into the milk, yolk and juice mixture. Fill the crust and bake as directed in the recipe. Makes for a lighter textured pie and cuts a bit of the sweetness. Plus it uses up those pesky extra whites.
FWIW – I have made variations of this pie using real key limes, bottled key lime juice, RealLime lime juice and fresh juice from standard limes. They ALL work and they all make delicious pies. The fresh lime juice just makes an EXTRA delicious pie…
Great ideas, thank you for suggestions and also for sharing your information about the lime juices. Super helpful!
