Instant Pot Key Lime Pie

I love key limes, and this super easy Instant Pot key lime pie is a perfect dessert for a small group. Made in a 7 inch springform pan, the pie serves up about 4 slices. My husband absolutely loves key lime pie, so this pressure cooker version is perfect for us. I made the pie one day, and we had dessert for several days from it. If making this for a crowd, simply make additional pies. 

This Instant Pot key lime pie recipe can be made in about 40 minutes total, but it is best if it sets in the refrigerator for several hours. So give it a bit of time for that! For a bit of history, Key Lime pie originated around 1935 with ice box key lime pie from the Florida keys.

The Best Instant Pot Key Lime Pie

A key lime pie recipe is very easy to adapt to a pressure cooker or Instant Pot.  Begin by spraying a 7-inch springform pan with cooking spray, or rubbing a bit of oil on it. I use the springform pan that came with this Instant Pot accessories set.  You can also buy a pan separately, such as this Instant Pot springform pan

graham cracker crust

To make the graham cracker crust either grind the crackers in a food processor or put them in a baggie and roll over them with a rolling pin. You can even roll a can of something over them to crush them. No need to get high tech! I smashed mine up in a baggie out of laziness. I didn’t want to mess up the food processor just for a few cracker crumbs. 

Mix the graham crackers with melted butter and press the mixture into the bottom of the pan and up the sides. Then pop it in the freezer so set nicely while you make the key lime filling.

The filling is made with a mixture of egg yolks, sugar, sweetened condensed milk, and key lime juice. I used commercial Nellie & Joes Key Lime Juice because I did not have fresh key limes readily avaialbe. You can certainly use fresh squeezed key lime juice in this recipe, or you can also substitute fresh squeezed lemon and lime juice in a 50/50 mixture. If you use fresh limes, add about a Tablespoon of zest to the mix for additional flavor.

Pour your key lime pie filling into the pan and cover it with foil, making sure to leave no openings.  Then, make a foil sling to help place the pan in the Instant Pot for easy retrieval after pressure cooking. 

 

Put a trivet in the Instant Pot and add one cup of water. Then lower the key lime pie pan into the pot. Pressure cook on manual high pressure for 15 minutes, followed by 10 minutes of natural release. Then quick release. 

Remove the pie and let it cool for about 10 minutes. Remove the foil cover and refrigerate for at least 3 hours until the pie is set.  The pie should appear set in the center, but not look baked. For example, it will look glossy and jiggly, not baked and golden brown.

I served my Instant Pot key lime pie up with simple whipped cream. You can get fancier if you like and add lime slices, lime zest, or fruit, such as raspberries or blackberries.

Store your leftover key lime pie in your refrigerator.  One pie serves up four to six slices, depending on how small you slice it. I sliced it into six.
