This has got to be the best key lime pie I have ever made. The recipe was so easy to make. My husband requests this pie at least once a month. It has become our all time favorite.” – Reba

“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!” – Joy

The Pie That Beat Birthday Cake


I stumbled upon this Key Lime Pie recipe in a small downtown shop when I was visiting Savannah, Georgia with my friend, Amie. I made it for my family when I got home and it quickly became a family favorite. It’s requested more on birthdays than cake!

When I make it, I always use our homemade graham cracker crust. It adds a buttery crunch and complements the citrusy filling of the pie. It’s the perfect dessert – creamy, refreshing, and simple to make. I hope you love it as much as I do!

Ingredients Needed

Ingredients in Key Lime Pie: Key Limes, Eggs, Sweetened Condensed Milk, Graham Cracker Crumbs, Butter and Sugar.
  • Graham cracker crust: I prefer to make my own homemade crust, however a store bought graham cracker crust works just fine and save a little time.
  • Key limes: Use fresh key limes whenever possible for the most authentic and vibrant flavor. If you don’t have access to key limes, bottled key lime juice is the next best option.
  • Egg yolks: This is what gives the pie its smooth, silky texture. You can use the extra egg whites to make this Lemon Meringue Pie topping or these delicious Coconut Macaroons.
  • Sweetened condensed milk: This balances the tartness of the key limes with some sweetness and gives the pie a rich texture.
  • Optional topping: I like to decorate the top of my pie with homemade whipped cream and key lime slices.

How to Make Key Lime Pie

Process photos with steps to make Key Lime Pie: making the graham cracker crust, juicing key limes, mixing the key lime pie filling, and pouring it into a crust
  1. 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.
  2. 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.
  3. 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 until blended.
  4. Bake: Pour the filling into the graham cracker crust pie shell. Bake for 15 minutes, then cool to room temperature and refrigerate until ready to serve.

Frequently Asked Questions

Can I use regular limes instead of key limes in key lime pie?

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 slightly, however many of our readers have commented that they’ve used limes and the pie turns out great.

Do I need to bake the graham cracker crust for or can I just chill it?

You can do either. Chilling the crust for an hour will set it, but baking it gives it a slightly toasted, firmer texture. Just make sure the crust is completely cooled before adding the filling.

How do I know when the key lime pie is done baking?

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, if at all. The top of the pie should not be browned at all.

Can I make key lime pie ahead of time?

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.

Can I freeze key lime pie?

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.

Notes

Lime Juice Tip: If using key limes, you’ll need about 15-25 key limes to get ½ cup of juice. They’re small but flavorful! No time to juice? High quality bottled juice like Nellie & Joe’s Key Lime Juice works beautifully as a substitute or in addition to fresh squeezed key lime juice.
Pie Crust Options: A graham cracker crust is a classic crust for this pie. However, you can switch things up by using vanilla wafers, gingersnaps, or Biscoff cookies in place of the graham crackers.
Storage: Store leftovers covered in the fridge for up to 3 days. You can also freeze the whole pie (without the whipped topping) for up to 2 months.

    1. Can’t say I have ever had Kutchie’s Key Lime Pie. I recently did a Key Lime Pie crawl in Key West and tried 10 different key lime pies and I can honestly say our recipe was right up there with the best ones we tried! It was right up there with Kermits and Moondog! In fact I would say the filling in our key lime pie is identical to the one at Moondog Cafe. You should definitely try it and see how it compares to your favorite!

    1. With this recipe you should be fine with the time and temperature listed since it is not one that you use yeast.

    I’ve been making this recipe for years and I’ve had people who hate key lime pie so they loveeee this one. Will always use this recipe.

  3. 5 stars
    This recipe rocks! Limes are my favorite citrus fruit. I love this recipe because I’m able to cheat if I’m in a hurry and need to use a premade gram cracker crust. I had to use the bottled juice but it was still amazing. So simple to make and it will impress guests!

  4. 5 stars
    I have a Key lime tree in the backyard. Finding recipes is fun, but finding a recipe that is delicious and easy is the best. Taking this winner to Easter dinner!

  5. 5 stars
