Key Lime Pie is one of my husband’s favorite pies, especially as the weather begins to warm up. For years, I professed that I didn’t particularly care for key lime pie. I always thought they were a bit too dense and either too tart or not tart enough. I know, I’m picky, but I thought there had to be a fine balance and wanted an updated version of the classic.

After experimenting with various changes in the method of making a key lime pie, along with subtle changes in the ingredients, I finally achieved a lighter, fluffier, key lime pie that I think is just perfect. It’s now my go to key lime pie recipe.

What did I do?

Well, I used the whole egg. While the egg yolks give the key lime pie such richness, the egg whites help to give the pie a lift. It alters the texture from a dense, thick custard to a silky, cloud-like confection. It might not be for everyone, but everyone that I’ve served it to has absolutely raved about it.

I also added in a bit of zest from the limes. It amps up the lime flavor and makes the pie a whole lot more interesting, I think.

    Hi Tanya,
    Yes! You can use the bottled key lime juice in place of fresh. If possible, I would recommend fresh lime zest, whenever you can. It makes a noticeable difference.

    Thanks for all the wonderful recipes! I’m trying this one next. Question: should the pie crust be pre-baked?

      Hi Angela,
      I do not prebake the pie crust for this key lime pie. Of course, you are welcome to but I like the texture of a firmly chilled graham cracker crust that just bakes along with the pie for this pie instead of pre-baked.

    Made this last night and was actually pretty disappointed. The taste was good but the pie was semi solid, and I baked it for the full time, followed the recipe exactly, and let it chill in my fridge for almost a full 24 hours. :( Sad because all the other recipes from your blog have turned out so well!!

      I’m so sorry it didn’t work for you, Katie! I know how frustrating that can be when you try a recipe and it doesn’t turn out right for you.
