This recipe is a tasty, fragrant, and refreshing dessert, which I highly recommend. It’s so good that you can’t stop at just one slice, and if you succeed in refraining from a second slice, you’ll be thinking about it until you give up. It’s SERIOUSLY that good, and I’m a little obsessed with this low carb key lime pie at the moment! 

I’m sure everyone will love this sugar-free key lime pie that’s incredibly easy to make using just 10 ingredients. However, since this keto key lime pie is not baked in the oven, it requires a few hours in the fridge. Waiting for it to firm up in the refrigerator is the hardest step of the recipe.  

The texture of this keto key lime cheesecake is super smooth, creamy, and it combines a sweet and tart low carb lime flavor.

Are Limes Keto-Friendly?

Yes, limes are keto friendly and can be used in a keto diet. Therefore, key lime juice or normal limes, both juice and peel or zest, can be used in various low carb dishes.

Is Key Lime Pie Keto?

A classic key lime pie recipe is an American dessert that features a graham cracker base, a creamy lime filling made with condensed milk, then topped with meringue or whipped cream. 

There are tons of variations on the original recipe, but unfortunately, none of them are keto-friendly. No worries though, we created this elegant keto-approved key lime pie that is ridiculously low in carbs, and no baking is included. 

While this dessert looks like hard work, I promise there’s no way to mess things up. Even if you’re a beginner, you can create the perfect no sugar grain-free dessert that will impress everyone.

Don’t tell anyone this pie is keto, and they won’t even notice!

Ingredients For This No-Bake Keto Key Lime Pie

You will need only a few simple ingredients for this no-bake keto lime pie, which you may already have in your pantry:

For the Crust

To make the crust for this pie, I used an almond flour mixture, but you can also use my keto graham crackers to replicate the original pie crust recipe.

keto key lime pie ingredients
  • Almond Flour- is my favorite keto flour alternative for no-bake keto recipes. Be sure you use almond flour instead of almond meal. If you don’t have almond flour on hand, grind some almonds in your food processor and use it instead.
  • Sweetener- Any keto powdered sweetener, such as erythritol, xylitol, monk fruit, or allulose, can be used. Just make sure you’re using a powdered form, so it blends easier.
  • Butter- replace it with coconut oil.
  • Vanilla Extract- I recommend using a high-quality vanilla extract you can get.
  • Cinnamon- optional, but make the crust taste like a graham cracker crust.

For the Lime Filling

  • Lime Juice- Freshly squeezed. Lime is very accessible and can be found in all stores.
  • Gelatin Powder-  is used to set the filling mixture.
  • Cream Cheese-  for the smoothest filling, make sure that the cream cheese is at room temperature.
  • Lime Zest- this is optional, but I used it for an extra flavor.
  • Heavy Cream- room temperature for easier mixing.
  • Vanilla Extract- this ingredient is never missing from my desserts, but you can replace it with some lime extract.
  • Sweetener- use powdered sweetener for the filling to avoid any lumps.

How To Make This Delicious No-Bake Keto Lime Pie

If you follow the next few easy steps, you will end up with one of the best keto desserts you will ever try.

how to make keto key lime pie recipe
  1. Start by making the keto pie crust: Combine all the ingredients for the crust until you have a sandy mixture.
  2. Press evenly into the bottom of a pan and chill while preparing the filling.
  3. Make the keto key lime filling: Combine the gelatin powder and lime juice in a small bowl, then microwave for 40 seconds.
  4. In another bowl, mix the rest of the ingredients, add the gelatin mixture and mix well.
  5. Chill the pie for at least 8 hours after spreading the cheesecake filling over the crust.

Tips For Making This No-Bake Keto Key Lime Pie

  1. You can also use lemons, but I recommend looking for lime. They give the specific key lime pie flavor.
  2. Use room temperature ingredients, so all the ingredients combine smoothly.
  3. Line the pan with parchment paper so you can release the pie and transfer it to a cutting board for easy slicing. 
  4. I always make this keto key lime pie with cream cheese the day before serving it to give the pie enough time to firm up for clean cuts. Also, chilling overnight allow the flavors to develop.
  5. Make sure that you don’t boil the gelatin and lime juice. Boiling the gelatin destroys it and may weaken the gelling ability.
  6. Use a hot knife to cut the cheesecake evenly.

Key Lime Vs. Regular Lime

  • If you’ve ever seen a key lime next to an ordinary lime, you’ll notice the difference immediately because limes can be found in many shapes and sizes.
  • Key limes are known for their “bouquet” and intense flavor. They are used to garnish and flavor seafood, provide a tangy touch to drinks and give normally sweet pastries a zesty aspect. 
  • Key limes are more difficult to find than conventional ones, and finding some will take more work.

How To Choose The Perfect Limes

When you touch the lime, it should feel juicy; do not take it if it seems dry. Wash well so that no wax remains.

When grating the lemon zest, you should know that only the green part is good, the white one is bitter.

How To Store Sugar-free Key Lime Pie

This refreshing no-bake key lime pie can be stored in the refrigerator or in the freezer.

  • Fridge: This keto key lime pie will stay fresh covered in the refrigerator for 4-5 days.
  • Freezer: If you want to store low carb key lime pie cheesecake in the freezer, cover it with plastic wrap and put it in the freezer, where it can be stored for up to two weeks. When ready to serve, remove the key lime keto pie from the freezer and allow to thaw in the fridge for a few hours.
