The uses are practically endless.
I used a Microplane zester to make the lemon zest in this recipe fine enough so that you don’t need to strain the zest from the curd after making it.
That made life much easier and especially since I don’t seem to own a fine-mesh sieve. I will have to remember to put that gadget on my holiday gift list.

Keto Sugar Free Lemon Curd
- 3 large eggs room temperature
- ⅔ cup powdered low carb sweetener
- ½ cup fresh lemon juice juice of about 2 large lemons
- 1 ½ teaspoon finely grated lemon zest use a Microplane zester to grate fine enough so no straining of curd is needed.
- 4 tablespoon butter room temperature diced
- In a small saucepan (not heated yet), combine sweetener, lemon juice, lemon zest, and whole eggs. Whisk until combined.
- Add the butter and cook over medium-low heat, while stirring continuously with a whisk or wooden spoon, until the first bubble appears and the curd is thick enough to hold marks of the whisk or spoon, about 4-7 minutes.
- Strain with a mesh strainer if needed. Transfer the warm lemon curd to a jar and cover the surface with plastic wrap.
- Refrigerate until cold, then remove the plastic wrap and replace it with a lid. The lemon curd will keep fresh in the refrigerator for about 1 week. Makes just under 2 cups.
Made the lemon curd tarts. Outstanding! We are going away with three other couples and I'm making several keto desserts among which will be the tarts. I will not tell them that they are keto, and they will never know. (Of course, I'll let them know after they rave about how delicious the tarts and.) My guess is they'll fight over who gets the last four, lol. Thanks for an amazing recipe. And you are right, the portions keep us from eating too much which in this case is very easy to do!
Thank you, Marilyn, for trying the tarts, your very kind words & for sharing your experience. I know what you mean, if I made this into a whole pie, I would eat the whole pie, lol.
Could this be canned and put on shelf like the stores? Would like to make for gifts- it’s so good thank you
Hi Deann, I'm pretty sure it could be canned and vacuum-sealed and stored on a shelf if you have a pressure cooker or other canning process.
Does it thicken up after it’s cold?
Kathy, yes, it does get thicker after refrigeration.
Looks so luscious! I could just eat it all with a spoon.
I love lemon desserts too! They're just so refreshing!
This is so delicious. We especially love it this time of year when the weather starts getting cooler and the fresh berries are still available in the markets - that last taste of sunshine! SO good with fresh berries and whipped cream! 🙂
Thank you for this wonderful recipe! My mouth is watering at all of the delicious possibilities!
I'm tasting a lemon tart with this beautiful curd! Smooth, creamy and zesty!
Girl, you're reading my mind!
SO thick and creamy! I love lemon desserts and this one's a winner.
