So one thing you can’t get here in Belize is lemons, which I found weird because I’ve always considered it a tropical citrus fruit. I was surprised to find that there are lots of green limes and even green oranges, but not a single festive yellow lemon to be found anywhere here on the island of Ambergris Caye.

Knowing that from our scouting visit in February before we moved, (and because I really wanted to use this super cute lemon juicer I got at Target this winter) I decided to make this Keto Lemon Pie in New York before we left.
When I say before we left, I mean RIGHT before we left! I wish I’d taken a photo of the actual kitchen when I was trying to get these keto lemon pie pictures done, because we were literally moving out while I was finishing it!
Being a serious lover of lemon desserts though, I was determined to get this low carb lemon pie done in case it was my last keto lemon dessert for awhile!
And it will likely be – but what a way to go out!

This keto lemon pie is intensely lemon flavored in the best possible way. The keto crust is a combination of my coconut crust for the Strawberry Swirl Cheesecake, and my almond shortbread cookie recipe. It’s sweet and toasty and sturdy enough to literally pick up the piece of pie with your hands to eat it.
You know, for when you’re standing in front of the open fridge at 2am and you don’t want to dirty any dishes (or have anyone hear your fork clinking against the plate and wake up to catch you eating lemon pie out of the fridge in the wee hours….or maybe that’s just me….) so you just grab a piece and eat it standing there, reveling in its sweet, lemony goodness.
Yeah, that.

This keto lemon pie got me through the last couple of days of stress before we finally left for Belize. I even brought the leftovers with me to a friend’s house that we were staying with between the time we’d moved out and when we actually left the country! Which was bad because then I had to share – but it was a hit even with the non low carbers!
For science, we tried freezing the last few pieces of this low carb lemon pie to see if it would be good. It was OK once we’d thawed it for a few minutes, but honestly I like the contrast of the pillowy lemon filling against the crunchy, toasty crust better when it’s just chilled in the fridge.

You’ll have to make it and let me know which you prefer!
As if there wasn’t enough to love about this keto lemon pie – it’s really easy to make! The crust bakes alone and the filling is made with my low carb lemon curd (which can be made in advance and kept on hand in the fridge), folded into some lightly sweetened whipped cream.
That’s it.

My point is, you could be eating this keto lemon pie in less than an hour!
Well? Why are you still here?!?!?
Go! Go! Make it and be sure to report back!!!

Description
Lemony and sweet, this refreshing low carb lemon pie recipe is easy to make and perfect for any summer party! Keto, Atkins, Sugar Free, and Gluten Free!
Ingredients
For the Crust:
- 6 tablespoons butter, softened
- 3/4 cup erythritol (I used Swerve)
- 3/4 cup dried shredded coconut (unsweetened)
- 3/4 cup super fine almond flour
- pinch of salt
For the Filling:
Instructions
For the Crust:
- Combine the butter, erythritol, coconut, almond flour and salt in a medium bowl and mix until a dough forms.
- Press the dough into a pie plate, going all the way up the sides.
- Bake the crust at 350 degrees (F) for 15 minutes, or until golden brown.
For the Filling:
- Melt the butter in a small saucepan on low heat.
- Remove from heat and whisk in 1/2 cup sweetener, lemon juice, and lemon zest until dissolved. Whisk in the egg yolks and return to the stove over low heat.
- Whisk continually until the curd starts to thicken.
- Remove from the heat and strain into a small bowl. Chill.
- In a large bowl, whip the heavy whipping cream, xanthan gum, and 1 Tbsp sweetener together until stiff peaks form.
- Fold 1/3 of the whipped cream mixture into the chilled lemon curd until combined.
- Add the lightened lemon curd mixture to the remaining whipped cream and gently fold together until fully combined, but still fluffy.
- Spoon the filling into the cooled pie crust. Garnish with additional whipped cream and lemon zest if desired.
- Serve chilled – will keep up to a week in the refrigerator.
Notes
Note: Your crust may slide down a bit during baking. Once you remove it from the oven it will remain soft for about 10 minutes before hardening. If it’s slid down, wait five minutes, press it back into the shape you want and let it cool and harden before filling.

The pie looks so tasty! But something is wrong with the the build-in metrics calculator.
3/4 cup super fine almond flour = 19 grams, but 19 grams (regular) almond flour is only 2,5 tablespoon, not 3/4 cups.
And 3/4 cup dried shredded coconut should be 53 grams instead of 70 grams.
Could you weight the ingredients yourself? That would make the recipe so much more reliable.

Sounds like you didn’t cook the curd long enough for it to thicken Tracy, sorry you didn’t enjoy this one.
Tracy says
The curd was quite thick in the pan and well…curdled lol. I think without guidance of just how thick, or how long it should take, I was forced to wing it with this recipe, and you’re probably right. Unfortunately, I still feel that there was way too much sweetener called for, and probably won’t attempt this one again.
