This Sugar-Free Lemon Pie is a delicious, low-carb lemon pie with coconut flour pie crust and sugar-free lemon curd. It’s gluten-free, paleo, keto for a low-calorie lemon pie, and perfect for a light, fresh dessert to serve with fresh strawberries or a sugar-free meringue.
I love making pies, in particular healthier versions of classic pies, like my Sugar-Free Coconut Cream Pie, Keto Avocado Key Lime Pie, or Keto Pumpkin Pie. Pies are the best dessert, or at least it’s my favorite, because it a combination of a crusty base with a sweet and creamy filling.
Plus, I love the subtle flavors you can add to pies and they are (generally) quite easy to whip up even if you’re not a pro baker!
Why You’ll Love This Sugar-Free Lemon Pie
Lemon curd pies have always been my favorite among pies. However, it took me six months before I managed to make the perfect sugar-free lemon pie. The sugar-free lemon curd is not acidic, perfectly sweet – sweetened with sugar-free crystal sweetener – I used erythritol or sometimes monk fruit sugar.
What I love about this new recipe is the crust! I made an easy 4-ingredient coconut flour pie crust ready in 5 minutes in my food processor. It is a healthy pie crust I use for any low-carb keto pie.
Ingredients and Substitutions
- Lemon Juice – You can either get fresh lemon and squeeze the lemon juice yourself or buy lemon juice.
- Eggs – This recipe requires full eggs and additional egg yolks to make the meringue.
- Unsalted Butter – I like to choose grass-fed butter, it tastes better.
- Sweetener of Choice – I’ve made the recipe with erythritol, but any granulated sweetener will do the job just fine.
How To Make Sugar-Free Lemon Pie
Making this pie is very easy. Start with the crust and jump to the filling after. Sometimes, I love to add a tiny bit of fresh vanilla to the dough. Very optional, but it is a simple addition that makes a big difference. Coconut goes so well with lemon!
You can make this sugar-free lemon pie with different toppings. The meringue is not difficult to create without sugar. If you buy an excellent sugar-free crystal sweetener like erythritol or monk fruit sugar, it will work like a charm.
In the picture below, I used my Low Carb Almond Flour Pie Crust recipe – that’s why it is not as white and shows you a different option! You can also use the sweet version of my keto pie crust.
In summer, you can add fresh strawberries and a drizzle of sugar-free chocolate on top of the pie. I recommend preparing the meringue just before serving the pie. I have a blow torch to burn the surface and keep the meringue soft.
But you can also bring the sugar-free lemon pie back in the oven for a few minutes on grill mode to brown the top.

Sugar-Free Lemon Pie
Ingredients
Sugar free Lemon curd
- ½ cup Lemon Juice or juice of about 5 small lemons
- 2 Egg
- 2 Egg Yolk keep egg white for meringue
- ½ cup Unsalted Butter or coconut oil, melted
- ¼ cup Granulated Sweetener erythritol or monk fruit sugar
Soft sugar free meringue frosting
- 2 Egg Whites
- ¼ cup Granulated Sweetener
Instructions
- Prepare the Coconut flour Pie Crust following my blog recipe.
Sugar-Free Lemon Curd
- Whisk the lemon juice, sweetener, eggs, and egg yolks together in a saucepan.
- Bring to medium heat and add the coconut oil or butter, stirring continuously, to prevent the eggs from cooking and scramble.
- When the coconut oil is melted, increase the heat to medium-high, keep stirring until it thickens up.
- When thick, remove from the heat and transfer the curd to a bowl to cool down at room temperature for 15 minutes.
- Fill in the coconut flour pie crust with the lemon curd. Refrigerate the lemon pie for at least 2 hours to firm up.
Sugar-free meringue frosting
- In a bowl whisk the egg white until it starts producing a good volume. Usually 30 seconds on high speed.
- Keep whisking on high speed and slowly add the sugar-free crystal sweetener of your choice.
- After 1 minute and 30 seconds, the meringue should be really fluffy and triple its volume.
- Turn the bowl upside down to check if the meringue is ready. If it sticks to the bowl, transfer on the lemon curd pie. If it doesn't stick, keep whisking.
- Torch the top of the meringue or place 2 minutes in the oven with the grill on until the top is slightly brown.

I have splenda can I use that?
There are many different types of Splenda. You can use their 1:1 Sugar Alternatives (Erythritol-based), but not their dextrose or maltodextrin sweeteners that aren’t suitable for baking.
The filling is very good but somehow there are always egg white pieces in the batter, I have to strain it. Next time I’ll use 5 yolks instead. I bake the meringue in oven, no broiler. Will make it again.
Do the nutrition facts for the lemon pie include the crust?
Yes it does.
I’m diabetic and cannot follow the NET carbs, I have to follow FULL carb restrictions. I’m so pleased to have found you, no one else has mentioned Monk Fruit sweetener which I just bought and almond flour. I have superfine blanched almond flour. I will try to figure out the amount of carbohydrates per 3 oz. slice. Thank you for this crust recipe.😘
Can I use xylitol?
Any sugar free crystal sweetener works so yes xylitol is fine
Hi, thanks for the recipe. I want to ask about the serving size. Pie crust recipe says for 12 people but the pie recipe says for 8 people. Thanks for your reply.
The lemon serve 8 slice, nutrition panel is for that serving. Nutrition panel for the crust alone has been given for 12, which make small slices, but you can make use the same recipe and cut into 8 slice, it is up to you
Wonderful and dead easy lemon curd. I didn’t use this crust recipe but everyone raved about the lemon pie.
thanks for sharing
Awesome recipe and super lemony! This was a hit even among the non-keto peeps. Will definitely be making it again.
Lovely recipe
Can I freeze the lemon curd?
I am sure you can freeze it in an airtight container and defrost the day before in the fridge, Enjoy! XOXO Carine
Do you have a sweets cook book ?
No
Not yet but on my mind 🙂 Subscribe to my newsletter and you will be the first to now it if it comes out! XOXO Carine.
how many eggs we need if we want make it for 8 people?
You can follow the exact same recipe and cut in 8 even slices. That is the best way to serve 8 people with this recipe. Enjoy the low carb recipes on the blog. XOXO Carine.
i love this but after using stevia in the curd it tastes artificial, do you have any suggestions?
I am using erythritol or monk fruit stevia blend in this recipe not pure stevia! Stevia is way too bitter and strong for baking. Make sure you use the same brand as I do for success. You can find the product on Amazon. Enjoy the recipes on the blog. XOXO Carine.
I am new to sugar free baking. and I am confused by the sugar free substitute for sugar. in the strawberry sugar free lemon pie. Can I use Truvia, .the spoonable type,. for the sugar substitute? If so, do I use the amount called for in the recipe?
Thank you.
I am not familiar with truvia, it is not sold where I live in New Zealand, but any sugar free blend made of stevia and erythritol are perfect for this recipe. Enjoy! XOXO Carine
II am new to making sugar free pastries. Can I use spoonable Truvia for the sweetner in both the crust and the lemon curd? Do I use the amount specified in the recipes?
Thank you for your help!
If truvia is a blend of erythritol and stevia that can be use as a 1:! ratio sugar substitute, then yes, same amount is fine. I never used Truvia before, not sold in my country so I am unsure how it works. Enjoy the sugar-free recipes on the blog, XOXO Carine.
Fait le 10 mars 2018. Remplace par sucre blanc mais 1/8 de sucre la prochaine fois mettre 1/4 de tasse de sucre, fait avec fraises et chocolat
Hello…Will definite try it!! Thanks for sharing. Just one question, how much gr of coconut oil should i use? It doesnt says. Thanks 🙂
Hi! I am so sorry for the missing ingredient! I just updated the recipe card 🙂 I used 1/2 cup coconut oil for the lemon curd ! You’ll love this simple lemon pie. Thanks for reading the blog or should I say proofreading !!! haha XOXO Carine.
Hi! I’m in the middle of making this pie. I’m up to the meringue part, but I noticed that it doesn’t have to be cooked at all. Is this safe for consumption since they are raw egg whites? If anyone has an answer I would really appreciate it!
Yes it is ! Many French dessert contains raw egg white like chocolate mousse or pie meringue. You can return the pie to the oven at 80C to brown the top if you like but it is optionnal. Make sure you store the pie in the fridge and eat within few days. Enjoy, XOXO Carine.
This looks so yummy! Nothing better than a fresh lemon tart!
So true! Lemon are available all the year and it is always a winner dessert. I just checked your blog BTW, it is such a great source of Low carbs recipes. I will try some of them soon 🙂 See you soon on the blog Vicky. Carine. xx.
