Best Keto Key Lime Pie Recipe
I might be just a little bit obsessed with this low carb key-lime pie. And while I don’t consider myself to have a major sweet tooth, there are times when it’s nice knowing that I can enjoy a piece of pie without having to overly worry about my carb counts.
What’s great about this low carb pie is that it’s made using real key lime juice and key lime zest, so it does a great job of packing in delicious key lime flavor.
It’s also a great keto pie to bring along to a family or friends gathering if you aren’t confident, there will be a keto dessert there that you can eat. But be ready…once people get wind that a key lime pie is there, they’ll be lining up to get a piece. Once you tell them that it’s keto-friendly and low carb, they won’t believe it tastes so creamy and delicious!
Is this sugar-free key lime pie easy to make?
In all reality, it is. While there are several steps and ingredients involved, I can assure you that the result is worth it.
I’ve made quite a few sugar free pies, and this is one of the best since Key Lime Pie is towards the top of my list of favorite desserts.
Tip: When making the pecan pie crust, it’s best to use a food processor or blender to get pecans very finely chopped. They need to be in tiny pieces so that they form a crust to hold together all of that delicious pie flavor.
Where can I buy key limes?
Most grocery stores carry key limes for you to purchase, but they may only offer them seasonally depending on where you live. Check in the produce section and look for key limes that are a bit squishy (but not too much!) to ensure that they’re ripe and will have a lot of key lime juice to use. If you can’t find key limes, regular limes will work, but it may take a little more juice and zest to get that tart flavor.
Tip: Before you start zesting, give the outsides of the lime a good cleaning! Scrubbing away dirt and grime is key, so it doesn’t end up in your mixture. I always soak mine in warm water with a little vinegar for a few minutes before scrubbing.
How many net carbs are in this sugar-free pie?
If you follow the recipes as it is below, there are five net carbs in a piece of this keto key lime pie. Not bad, right?! Now that you know the carb count, you enjoy this delicious pie guilt-free knowing it won’t derail your progress.
How to Store Keto Lime Pie with Pecan Crust
Once you’re made this sugar free key lime pie, make certain to store it properly. After freezing it so that it sets up, you can store it in the fridge, but it will soften like a pudding or mousse consistency. If you want more of an icebox pie consistency, you can store it in the fridge then set it out a bit before serving so that it thaws enough to slice. It depends on the what consistency you prefer as to if you want to keep it in the freezer or fridge.
Is it possible to freeze this sugar-free key lime pie?
You can freeze this low carb pie for later if you’d like just make sure that it is in a freezer-safe container. I would suggest slicing and freezing individual pieces so that you can grab a delicious piece of keto key lime pie when a craving hits.
Keto Specialty Ingredients You’ll Need to Make this Keto Pie Recipe
This low carb pie recipe contains only two ingredients that are considered keto specialty ingredients. Since those who follow a keto or low carb lifestyle avoid regular sugar, a sugar-free substitute is needed. I have found that Lakanto Monkfruit is the perfect substitute that cuts out refined sugar and still gives a sweet and delicious flavor.
- Lakanto Monkfruit Classic – You can also swap out for Swerve Granular
- Lakanto Monkfruit Powdered – Always my go-to choice! You can also consider Swerve Confectioners as well.
If this is your first time making homemade keto whipped topping you’ll love how quickly and easy it comes together plus you avoid so many processed ingredients.
My tip to you for making this delicious Keto Key Lime Pie with Pecan Crust?
Use your kitchen appliances to make the mixing a breeze. This is not one of those recipes that can be easily made with a whisk. You’ll need a good stand or hand mixer to get the delicious creamy filling with cream cheese and heavy cream to mix smoothly for this sugar-free pie.

Would some xantham gum help it to set without freezing?
I have only tested it as is so I’m not sure.
I hated Keto desserts until I found this one!!!! We love it!!! Thank you so much…
Fantastic. So glad you loved it!
I’m totally confused about the storage instructions. So I should freeze it for two hours, then put it in the fridge until 1-2 hours before I’m ready to serve, and then put it back in the freezer for an hour or two, then take it out and serve? Will it be frozen when I serve it? The alternative instructions say to keep it in the fridge and then let it sit out on the counter for 30 minutes before serving, which sounds like the complete opposite of the previous instruction. Won’t it be soupy if I take it from the fridge and leave it sit on the counter for 30 minutes? Can’t I just freeze for two hours, then store in the fridge and serve straight from the fridge?
Placing it in the freezer simply firms up the pie and makes it easier to cut and serve.
Just a heads up on how to tell if Key Limes are ripe, they turn yellow. If you are using green, they are not ripe yet.
Thanks, Lacey. I appreciate the helpful tip.
So is it better to use green or yellow ones? I almost never see key limes in the store and when I do they’re green. Should I buy green and let ripen before use?
I can’t wait to try this! My husband’s favorite dessert is key lime pie. Kasey, when I meet people who ask about keto recipes, I always send them to your site.
My husband started on a keto diet about 8 months ago and has stuck to it so well. I wanted to make him something sweet that wouldn’t throw him off his diet and tried this amazing recipe! It’s so easy and absolutely delicious! My kids loved it too!
So glad y’all loved it. Tell your hubs congrats on the keto lifestyle! There are so many great sweet recipes on my site. Thanks for the comment and review!
We have a tree nut and peanut allergy in our house so cannot use nuts. Do you have a suggestion for an alternate for them in the crust? Thank you!
Hey Renee, My daughter is off the charts allergic to all nuts. That is why my recipes use coconut flour instead or almond flour. Yeah this is tough though. There are some recipes that just don’t have great alternatives for certain ingredients. Some keto pie crust recipes use coconut flour but I haven’t tried this. Let me know if you try it and how it turns out.
