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

Ingredients to make Key lime pie, including sweetened condensed milk, sugar, crushed graham crackers, butter, eggs, and Key West lime juice.


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.

Frequently Asked Questions

What is the difference between key limes and limes?

Key limes are smaller, more tart, and more fragrant than regular limes. If you can’t find fresh key limes, use Nellie and Joe’s Key Lime Juice or regular limes as a substitute.

What color should my pie be?

Authentic Key Lime Pie is a pale yellow-green. Skip the green food coloring unless you want a brighter green for an occasion like St. Patrick’s Day.

Can I use a store-bought graham cracker crust?

Yes! A pre-made graham cracker crust saves some time and makes this recipe even easier.

We’ve had over 100 reviews from people who love this recipe as much as we do. Here are just a few:

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.

  • 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.

  1. How do you add the meringue topping? Do you bake the key lime first then reduce the temp and add the top and then bake the extra 10 minutes or add the topping before baking the key lime?

    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.

    1. Thank you for the compliment! I love this recipe. It turns out perfect every time. I’m also a fan of the tartness of the pie. I’m so glad you like it!

    1. We haven’t tried freezing it before but it I’m sure it is possible. I wouldn’t keep it frozen than more than a couple weeks, if it were me. I don’t like the freezer flavor so the less time in the freezer (at least for me) the better!

      1. 5 stars
        Love this recipe, I use 1/2 cup of freshly squeezed key lime right from my tree! Perfect pie everytime!

  3. 5 stars
    Sounds very delicious, as I live in Brazil, can you tell
    me what the crackers are and what can I use as a substitute.?
    We have wonderful limes here in Bahia , can I use all this juice etc.

    Thank you so much.

    1. Hi Hugo– Graham crackers might be tricky to find in Brazil. If you can’t find them, you can use Nilla Wafers, ginger snaps, or any kind of plain vanilla cookie. Even animal crackers. Hope this helps!

    1. You can make this probably 2 days in advance … I wouldn’t do much longer than that. Hope this helps!

    I am not huge fan of Key Lime pie but husband loves it. I made this recipe a couple of weeks ago and he said it was the best ever. I tried it and I really liked it. I am making it again today. Thank you.

    1. So glad you and your husband liked it! This is our favorite recipe for Key Lime Pie hands-down (and we are big fans too)!

      1. Do you have to refrigerate the pie to firm it.I put it in the oven at 350 degrees and it rose up some but still had a lot liquid.so I put it in refrigerator.

        1. That should be totally fine. If it was still liquid-y I would but it in the refrigerator to firm. Hope this helps!

  5. This may be a silly question but would it be okay to just use a 1/2 cup of fresh squeezed lime juice?

    1. Yes, you can definitely do that. The key lime juice has a slightly different flavor, but either will taste great!

  6. all one has to do is remember the color of the inside of the lime….it is never bright green. Take it from there.

  7. I’m so excited to make this! This may sound like a dumb question, but in your ingredients you say you need 1/4 cup lime juice but in the method it says you put half a cup in. Is this on the basis that you’d be getting 1/4 cup from the actual lime but then you must add another 1/4 cup of lime juice? Sorry, it’s probably a silly question but I don’t want to accidentally make the most sour pie in the world haha. Thanks x

      1. In this particular recipe for the key lime pie….notice the canned milk used, it is very sweet, and believe me condensed milk takes
        it to another level of sweetness. So go ahead and use what the recipe indicates. No fear!
        There are many recipes out there for this pie, and i have tried them all……

    1. If you live in St.Louis Dierbergs market carries key limes. But it is not necessary..I use the liquid from Nellies & Joes and it tastes fine. I have made at least 5 of these pies this month. It has been so cold and this just screams…warmth and sand and sun!!!

    2. that is easy….ever heard of Roses lime? Used
      in making margaritas…..it works in a pinch…
      And it is tasty.

      1. Sel, with all due respect, as the owner/operator of a chain of nightclubs, we use Rose’s in mixed drinks, but my opinion is that it has a twinge of bitterness after taste to it, which might not translate well into this recipe. Same as grocery store bottled lime juice (ReaLime brand), which is not nearly as clean and bright in flavor as real squeezed limes. Although, its companion brand “ReaLemon” is totally satisfactory to use in place of real squeezed lemons, and does not have that “off” after taste that Rose’s and ReaLime has. Note, that I have not tried your suggestion in this recipe so I could stand corrected. Just a cautionary.

    3. You can make this with regular limes. Key limes are preferred, but if you can’t get them, just use regular limes. Also, most markets sell key lime juice. That is another great option. But don’t sweat this – it will still taste great either way. 🙂

    4. 5 stars
      I have made this pie on 3 different occasions and it has been a crowd pleaser. As others have noted, this is a very easy recipe to follow to achieve a well balance of flavor and creamy textured pie.

    I made this key lime pie for Sunday dinner and my family said it was the best key lime pie ever. I loved that it was so easy to make.
