Did you know about 20 years ago I took Culinary Arts at my local community college? The program was quite comprehensive and I fully intended to work in restaurants upon graduation. Instead, we bought a house in another town and began our adoption journey.
A favorite recipe I learned how to make in class was lemon curd. I had always thought that making it would be hard but it’s super quick and easy. No fancy equipment here – just a pot and a whisk!
The best sugar-free lemon curd you will ever eat!
It’s not surprising that often times the foods that are the most delicious are the foods that are the simplest to make. This easy lemon curd recipe is no exception. It’s tangy and bursting with bright lemon flavor. It’s so delicious I could eat it right off the spoon.
My sugar-free lemon curd gives you all the tangy flavor of traditional lemon curd with no added sugar. Instead I use a natural low carb sugar alternative: an erythritol and stevia blend which measures 1:1 for sugar.
Are Lemon Curd and Lemon Pie Filling the Same?
No. Lemon curd is a tart spread flavored with lemon juice and zest. Its main ingredients are eggs, sugar, and lemon. It’s cooked on the stove like a custard and served chilled.
Lemon curd is slathered on bread and pastries at breakfast, spooned over cakes and used to fill crepes, tarts and cakes. It is not a pie filling, but can be made into a pie filling upon altering the recipe.
Low Carb Lemon Curd Ingredients
A good lemon curd doesn’t call for many ingredients. Mine calls for whole eggs, egg yolks, lemon juice, lemon zest, butter, and natural low carb sweeteners.
Adding a tablespoon of arrowroot/cornstarch helps thicken this into the most beautifully silky custard. Although, the cornstarch or arrowroot is optional, don’t omit if you plan to use this lemon curd to make my lemon curd pie. Omitting the starch lowers the total carbs for the whole recipe by 7 grams and results in a thinner (runnier) spread.
What Kind of Lemons Should I Use?
Lemons are the star of this recipe, contributing the citrusy bright flavor that I love so much. Because they are so important, you need to make sure you use the right lemons. To get the nice tart zing in this low carb lemon curd, make sure to use tart lemons like Eureka or Lisbon not Meyer lemons, which are much sweeter and less acidic.
If you taste this and find that it is a little too tart for your liking, balance the tartness out by using a little more low carb sweetener. If the lemons are more watery, which sometimes they are, and the flavor isn’t tart enough add 1-3 packets of True Lemon crystallized lemon juice. It can be found in the grocery store or on Amazon. They also make great lemon mug cakes!

My Favorite Low Carb Lemon Curd
- Measure the erythritol and arrowroot powder and put them in a medium pot. Stir together.
- Roll the lemons on the counter to get them juicy, then zest the lemons adding the zest to the erythritol.
- Separate 4 eggs and add the yolks to the erythritol in the pot. Add the 4 whole eggs to the pot and whisk the eggs and erythritol together.
- Juice the lemons and measure 3/4 cup. Strain the lemon juice and stir it into the eggs.
- Turn the heat to medium and continuously whisk the mixture until it begins to thicken – it only takes a few minutes. Turn the heat down to medium-low and continue whisking. The lemon curd will thicken – all at once
- Remove the pot from the heat and continue to stir with the whisk for one minute more. Pour into a clean container and add the stevia glycerite and salted butter incorporating completely.
- To cool, place a piece of plastic wrap right on top of the low carb lemon curd and refrigerate. I like to make a water and ice bath in a larger bowl, set the bowl with the lemon curd inside of the bigger bowl and stir the lemon curd until it is cool.
- Store in an airtight container and refrigerate up to 2 weeks.
- Makes about 2 cups. Serving size is about 3 tablespoons with 2.5 net carbs per serving.
