Authentic Key Lime Pie Recipe

Wednesday, October 23, 2019

Authentic Key Lime Pie has been a Thanksgiving and Christmas pie staple for along as I can remember along with about 8 different other pies for the holidays Granny would always make.

She was the ultimate pie goddess and her Key Lime Pie just happened to be in my top 3 favorite pies.



I'm sure Granny's love of Key Lime Pie originated during World War II when she was stationed as a Wave with my Granddad in Miami Florida. 

I now make a Authentic Key Lime Pie for myself family every holiday in her memory. It just wouldn't be the holidays without a slice of Key Lime Pie next to the Pumpkin Pie on my plate.

Sadly this pie was demolished in about 2.2 seconds between the 5 of us so I'm looking forward to another slice at Thanksgiving.

Granny would always add a few drops of green food coloring which I choose to omit for the natural color of the limes but if you prefer a green tint to your pie feel free to add a few drops until you achieve your desired color.

I wish she would have lived long enough so I could have asked her for a copy of her Key Lime Pie recipe and how she obtained it. But my recipe for Authentic Key Lime Pie will have to do.

Here's how I make my Authentic Key Lime Pie recipe.

Graham Cracker Crust in pie plate for Authentic Key Lime Pie recipe like Granny would make from Serena Bakes Simply From Scratch.

In a large bowl combine  12 whole graham cracker crumbs and 1/4 cup sugar.

Mix until well blended. Add 1/2 cup melted butter and stir until combined.

Press graham cracker mixture evenly across the bottom and up the sides of the pie plate. I find a measuring cup works well for pressing the crumbs evenly into the bottom and sides.

Bake crust in a 375 degree oven for 7 minutes or until lightly brown.

Egg yolks with lime zest for Authentic Key Lime Pie recipe from Serena Bakes Simply From Scratch.

To make Key Lime Pie filling mix together:

  • 4 whole Egg Yolks
  • 1 teaspoon Key Lime Zest or regular Lime zest if Key Limes aren't available
I prefer mixing the zest into the egg yolk to allow the natural flavor of the zest to be permeate the pie.

Egg yolks with key lime zest and sweetened condensed milk in mixing bowl for Authentic Key Lime Pie.

Add 14 ounces Sweetened Condensed Milk and mix until well blended.


Add 1/2 cup Freshly Squeezed Key Lime Juice, and stir until well combined.

Key Limes are more floral and a little less tart than regular Persian Limes. If you can't find key limes the persian limes will do, but please don't sacrifice flavor by buying bottled lime juice. Fresh lime juice is a must for Authentic Key Lime Pie and worth the elbow grease.

The key lime pie filling should smell amazing at this point.

Pour Key Lime Pie filling into prepared graham cracker pie crust for a favorite Thanksgiving Pie from Serena Bakes Simply From Scratch.

Pour Key Lime Filling into Baked Graham Cracker Crust and bake in a 350 degree oven for 15 minutes until set around the edge. 

If you don't like graham cracker crust you could always pre-bake a Flaky Pie Crust or Sour Cream Pie Crust. You could even make a Gluten Free Key Lime Pie recipe by using my Gluten Free Pie Crust Recipe for the crust.

Allow pie to cool completely and refrigerate until cold or preferably overnight to allow pie to set and flavors to develop.

Classic Key Lime Pie recipe covered in whipped Cream is an easy to make and a favorite Pie recipe for Thanksgiving and Christmas from Serena Bakes Simply From Scratch.

Serve with Homemade Sweetened Whip Cream and let your eye's roll back in your head with every bite!

This is lovely and I am glad there is no green food coloring to make it look more like commercial key lime pies! Delicious.

Hi Serena. To naturally food color, I have thrown in spinach to my Key Lime Pie since it doesn't have a taste. You might be able to literally blend it in with the sweetened condensed milk. Just a thought...it looks great!
