Instant Pot Key Lime Pie

Key Lime Pie

I’ve been on a mission to make the most out of my Instant Pot. Now that it’s wonderful steam isn’t needed to make baby food so it can be used for other wonderful things. Like dessert. I’ve been dying for a good Key Lime pie and this Instant Pot Key Lime Pie is it.

Key Lime Pie is one of my favorite desserts (next to Tiramisu). When I was expressing my excitement about making Key Lime Pie hubby mentioned that he didn’t realized it was one of my favorite desserts. He said because when we are out and it’s on the menu I never order it. I explained that I am very picky when it comes to Key Lime Pie and I don’t think that many places outside of Florida do it well. So rather than be disappointed, I just don’t order it.


Of course, that is part of my issue. Since sometimes the food I eat is tied to emotions or experiences I don’t order food I might be disappointed with (unless I made it). LOL.

For a long time I couldn’t find key limes so any dish that asked for key limes, I made with regular limes. But luckily the new supermarket in our town carries key limes. Yay! Key limes are a bit less tart probably because it’s a bit less acidic than other limes. To be honest, once the sweet condensed milk is added much of the tartness is neutralized. My point? Use whatever limes you have available, whether it’s a key lime or not.

Ha, ha key limes, limes grown in the Florida keys. Ok, I guess it’s not that funny. But it is delicious. Here’s the link to my Instant Pot.

If you don’t want to waste the egg whites, whip it up to make meringue. And if you do not have a spring form pan no worries divide the graham cracker mixture and key lime mixture and put it in pint size mason jars.

    1. Victoria,

      I must be honest I am not sure. I would assume you would have to increase the cooking time. I would increase it by half, allow it to nature pressure release and then check on it. It’s a custard so the top edge should be solid and pull away but the center will still be a little jiggly. Allow it to cool (making sure it’s completely cooked) then place it in the fridge to finish setting.

      I hope this info has been helpful.
