    Lemon desserts are simply my favorite, as you probably already know by the number of lemon treat recipes I have on this site.

    Lemon desserts are simply my favorite, as you probably already know by the number of lemon-flavored treat recipes I have on this site.

    This tangy but sweet, super low carb lemon curd recipe is so versatile and perfect for using as a pie or tart filling, in lemon bar recipes, lemon parfaits, or even served on low carb muffins or scones as a condiment.

    I used this lemon curd recipe in my Easy Keto Lemon Cream Fool recipe below:

    Easy Keto Lemon Cream Fool is a simple to make, low carb treat, which tastes like having a lemon cream pie in a glass.

     I  used it in this Keto Lemon Supreme Tarts recipe below also:

    Keto Lemon Supreme Tarts
    Keto Lemon Supreme Tarts are so sweet, tart, creamy, and refreshing with a buttery tart crust, a sweet whipped cream cheese layer, and a tangy sugar-free lemon curd layer.

    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.

    Common Questions About the Keto Sugar Free Lemon Curd Recipe

    Can I use lemon concentrate instead of fresh lemon juice in the recipe?

    For the best results, I recommend using freshly squeezed lemons.

    What do I do if my lemon curd curdles?

    You can strain the curd through a fine-mesh sieve if your lemon curd curdles.

    What do I do if my lemon zest turned out too large and not fine enough?

    If you did not use a micro zester then you may need to strain the curd through a fine-mesh sieve.

    What do I do if my lemon curd is sour and not sweet enough?

    You can add and stir in more sweetener to taste if needed.

    Equipment

    • 1 Lemon Juicer
    • 1 Microplane Grater Zester
    • 1 Mesh Strainer
    Prevent your screen from going dark

    Ingredients
     
     

    • 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

    Instructions
     

    • 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.

    Notes

    Tips:
    Try to use fresh lemon juice for lemon curd, not the store-bought prepared concentrate variety for a better-tasting result.
    Don’t use aluminum or unlined copper pans or spoons when heating the curd. They could have a reaction with the acids in the lemons and can discolor the curd and create a metallic aftertaste.

      Made the lemon curd recipe as written with 2/3 cup of allulose. Came out delicious with a zippy balance of tart and sweet. Will make again with lemons and perhaps other citrus when in season.

      I found the texture to be weird. I made a second batch and replaced the 3 eggs with 5 egg yolks. The 5 yolks provided a much better texture. I used the egg whites to make keto meringues.

      Can I pour the hot curd into a canning jar with a lid and let it cool to seal like with jam for long shelf life?

        Ruth, I have not tried that. It could work, but posibbly might work better to use the Instant Pot or pressure cooker method of canning.

      I made this yesterday with powdered Swerve and it tastes wonderful. After it got cold, though, it got a little grainy and crunchy. Did I use the wrong sweetener?

      Reply

        Hi Sheila, I used an allulose based sweetener because Swerve (erythritol) has a cooling effect and does tend to harden when it gets cold in creamy desserts.

      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.

      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! 🙂
