Is Lemon Curd Keto?
Regular lemon curd is not keto (so much sugar), but this easy low carb lemon curd is keto friendly! Each tablespoon serving has just 1/2 gram of net carbs.
For the smoothest lemon curd, the sweetener makes a huge difference! That’s why this recipe uses Besti Monk Fruit Allulose Blend. It dissolves effortlessly into the lemon curd, so it’s never gritty — with no added net carbs!
Ingredients & Substitutions
Here I explain the best ingredients for my sugar-free lemon curd recipe, what each one does, and substitution options. For measurements, see the recipe card.
- Butter – Use unsalted.
- Lemons – You’ll need about 3-4 whole lemons, as we’re using both fresh lemon juice and zest.
- Egg Yolks – Using the yolks only gives this lemon curd a luxurious texture. Make sure they are at room temperature before you begin. Save the whites and make a keto lemon meringue pie or keto bread!
- Besti Monk Fruit Allulose Blend – The best way to have all the sweetness of sugar without the sugar and carbs. Unlike other sweeteners (including erythritol and other brands of monk fruit sweetener), Besti dissolves completely and won’t crystallize, which is why it’s the only one I recommend for this sugar free lemon curd recipe. It’s also fine to use Besti Powdered — both versions dissolve easily.
- Sea Salt – To balance the sweetness.

0Is there a recipe for a CRISP Cookie? All that I find are actually soft style. I love lemon and would like a recipe for a low carb crisp lemon cookie. I thought of mixing a grated cheese with a sweetener and lemon zest and lemon flavor – kind of like they make cheese crackers, but I’m not confident formulating a recipe. Any ideas? It would certainly help keep me on low carb.

0I’ve never made homemade lemon curd before- didn’t realize it was this simple! I’ll have to try this the next time I make baked blueberry oatmeal bars, I love putting lemon curd on top of it!
