Creamy No-Bake Key Lime Pie is the perfect summer dessert. It’s tart, sweet, and so easy to make.

My husband loves his mom’s no-bake essential lime pie recipe, and he requests it every year for Father’s Day. I always misplace the recipe, so every year I call her to get it, and I’m reminded why he loves it: it’s creamy, tart, and the easiest no-bake key lime pie ever.

It is the perfect summer dessert made the old-fashioned way with simple ingredients. I use a store-bought graham cracker crust to make it easy – you can assemble the whole thing in about 10 minutes!

This year, after making my call to my mother-in-law, I picked up the ingredients at the store. She always recommends a specific bottled key lime juice, Nellie & Joe’s Famous Key Lime Juice, and this year I happened to notice the recipe on back of the bottle.

It was the same recipe my mother-in-law nicely repeats to me over the phone every year – I about died laughing! I had no idea that was the recipe she was using.

And it is the best no bake key lime pie recipe! The lime juice makes a huge difference giving this pie the best tart flavor.

Recipe Tips

  • This recipe does contain raw eggs, which is the classic way to make this no-bake pie. You should always use pasteurized raw eggs—they’re safer, but there are still risks. If you are worried, you might like to try my key lime bars instead.
  • This is the perfect make-ahead dessert because the filling needs to be set for at least three to four hours or, ideally, overnight.
  • If you can’t find bottled key lime juice you can use the same amount of fresh squeezed lime juice.
  • The pie will be kept in the refrigerator for several days. The filling may turn the crust a little soggy. I like to serve this pie within a day of making it and then enjoy any leftovers for a few days after that. The pie may not be as pretty leftover, but it’s still so delicious.
  • To freeze this pie, cover it tightly with plastic wrap instead of storing it in the fridge and pop it in the freezer. It will keep for up to three months!

This is the perfect dessert any time of year, but especially during the warmer months when a cool and creamy no-bake pie just hits the spot.

    There are two things in life that are always a joy – key lime pie and ANYTHING you don’t have to bake. Needless to say, I’ll be trying this pie!

    I’m from Lousiana and have tried a lot of key lime pies. This is hands down the best… by far. If you love tart, this is for you. It’ll give you a little bite back 🙂
