Nutritional Information
While traditional lemon curd is undoubtedly delicious, it can be high in carbohydrates and sugar, making it less suitable for those following a ketogenic diet. However, this keto lemon curd recipe retains the same tantalizing flavors while adhering to the low-carb principles of the keto lifestyle.
Keto lemon curd is typically made with a low-carb sweetener, such as zero-calorie monk fruit, instead of traditional sugar. This substitution helps to keep the carbohydrate content low while still providing the necessary sweetness to balance the tart lemon juice. Additionally, the use of fats, such as butter or vegan butter, ensures that the low carb lemon curd aligns with the fat requirements of the ketogenic diet.
In terms of macronutrient breakdown, see the nutrition facts in the recipe card. The nutrient profile makes keto lemon curd an excellent choice if you’re following a low-carb eating plan, as it provides a satisfying and flavorful treat without compromising their dietary goals.

How to Make Keto Lemon Curd
This keto lemon curd recipe is straightforward, easy to master and yields a little over one cup of lemon curd.
Ingredients in This Recipe
You need the following basic ingredients to make low carb lemon curd:
- Monk fruit sweetener or your preferred granulated sweetener โ I use monk fruit as a sugar substitute to provide sweetness without the added calories of sugar. It sweetens the keto lemon curd similarly to sugar but with a lower glycemic index.
- Lemon zest โ enhances the flavor and aroma of lemon curd especially if you rub it into the sweetener so it can release its oils.
- Salt โ enhances flavor and improves the texture of lemon curd
- Fresh lemon juice โ provides the distinctively tart and citrusy flavor that defines lemon curd.
- Egg yolks โ help thicken the lemon curd when heated
- Butter or vegan butter โ Butter adds richness and creaminess to the lemon curd, giving it a smooth and luxurious mouthfeel. You can also make this recipe with vegan butter which typically contains less saturated fat than butter.
Step by Step Instructions to Make Low Carb Lemon Curd
These instructions are also available in the recipe card below.
1. Use a fine grater or zester to grate the outer yellow zest of the lemon. Be careful to only grate the yellow part, avoiding the bitter white pith underneath. Then add grated lemon zest to low carb sweetener in a bowl.
2. Then stir lemon zest into sweetener.
3. Use your fingers or a spoon to rub lemon zest into sweetener to release the oils and distribute it evenly.
4. Add salt.
5. Put egg yolks in a medium saucepan.
6. Add the sweetener to the egg yolks.
7. Add lemon juice.
8. Whisk all ingredients together. Then transfer to stovetop. Whisk on low for one minute. Then increase to slightly above low but not to a medium flame. The lemon curd shouldn’t boil or bubble up. It’s important to be patient and maintain a gentle heat throughout the process, as rushing the cooking can result in a grainy or curdled texture. At about minute 5, the keto lemon curd will thicken into a smooth, velvety consistency.
9. Remove from heat. Then stir in butter and transfer to a clean container. Allow the keto lemon curd to cool completely before refrigerating it, as this will help it set and thicken further.
Tips for Perfecting This Recipe
First and foremost, use the freshest, highest-quality ingredients you can find. Opt for organic, unwaxed lemons to maximize the zesty flavor, and choose a low-carb sweetener that suits your taste preferences, such as monk fruit.
