The Best Key Lime Recipe from Savannah
This Key Lime Pie is smooth, creamy, and perfectly balanced between tart and sweet. I stumbled upon this Key Lime Pie Recipe in a small downtown shop when I was visiting Savannah, Georgia with my friend, Amie. Savannah has got to be one of the most beautiful and charming cities ever. We had so much fun touring the historic city squares, walking along the river, and eating delicious Southern food.
I made this pie for my family when I got home and we can’t get enough of it. It is the best key lime pie recipe! At family birthday parties, key lime pies are often requested over birthday cakes. Thanks to my trip to the Savannah, we now have another favorite family recipe!
Ingredients for Key Lime Pie
Graham Cracker Crust
- Graham crackers (crushed): For that classic, slightly sweet crust.
- Butter (melted): Holds the graham cracker crumbs together.
- Sugar: Adds a touch of sweetness to the crust.
Tip: Make the crust from scratch for the best texture and flavor, but a pre-made crust works in a pinch.
Key Lime Pie Filling
- Egg yolks: Creates a smooth, silky texture.
- Sweetened condensed milk: Adds sweetness and richness.
- Key limes: Fresh is best, but bottled juice (like Nellie and Joe’s Key Lime Juice) works great.
- Key lime zest: Enhances the tart, citrus flavor.
Optional Whipped Topping
- Fresh whipped cream, canned whipped topping, or meringue.
Tips for the Best Key Lime Pie
Use Fresh Key Limes: Use fresh key limes whenever possible for the most authentic and vibrant flavor. They have a distinct tartness that sets Key Lime Pie apart from regular lime pie.
Pre-Bake the Crust: This prevents a soggy crust and ensures a sturdy base.
Don’t Overbake: The filling should be set but still slightly jiggly when you remove it from the oven.
Serve Chilled: Allow the pie to cool to room temperature before refrigerating, then refrigerate for several hours or overnight before serving. This allows flavors to meld for the perfect taste.

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!

Absolutely perfect. I have tried many that did not set up or were too sweet. This is as good as the restaurant with the best key lime pie where I live. Thanks for sharing.

Ingredients
For the crust:
- 1/3 cup butter melted
- 1/4 cup sugar
- 1 1/4 cup graham cracker crumbs
For the filling:
- 4 egg yolks
- 6 key limes for zesting and juicing
- 14 ounces sweetened condensed milk
- Nellie & Joe's Famous Key West Lime Juice (if needed)
- whipped topping to garnish (optional)
Instructions
For the crust:
- Combine melted butter and sugar in a medium bowl. Stir in crushed graham crackers.
- Spread evenly into 9-inch pie plate and press onto bottom and sides to form an even crust. The bottom of a measuring cup works great for pressing the crumbs firmly into the pie plate.Chill for an hour until firm OR bake at 375-degrees for 5 min and allow to cool before filling.
For the filling:
- Preheat oven to 350-degrees. Zest key limes until there are 2 teaspoons of zest, then juice them. Pour the fresh key lime juice into a ½ cup measuring cup.If the ½ cup isn't filled, add bottled key lime juice to fill it completely.
- Whisk the egg yolks until they are thick and turn to a light yellow. Use a stand mixer or an electric mixer. Slowly add sweetened condensed milk while mixing on a low speed.
- Gradually add the key lime juice and zest and continue to mix on a low speed just until blended.
- Pour the mixture into the prepared pie shell and bake 15 minutes.
- Remove and let it cool to room temperate then store in the refrigerator until ready to serve.
- Serve with a garnish of whipped topping lime slices and little lime zest, if desired.
Notes
Substitutions
If key limes and/or key lime juice are not available, you can still make this pie!- Use Nellie & Joe’s Key Lime juice in place of fresh key limes.
- Substitute the juice of 1 lime in place of the 6 key limes. Make sure you have ½ cup of juice.
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..

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!
I made this last night. I found it to be way too sweet. Next time I will use a cup and a half of lime juice and five egg yolks.
Love this recipe! Thanks for sharing!
