How to Make Sugar Free Lemon Curd
This sugar free lemon curd is straightforward to prepare and delivers bright lemon flavor with a silky texture. Using a granulated sugar substitute such as Swerve keeps the curd low in carbohydrates and suitable for many low carb and keto meal plans. The method below produces a smooth curd that works beautifully on toast, scones, pancakes, yogurt, or spooned over berries.
Ingredients
- 2 large eggs
- 2 large egg yolks
- 1/3 cup lemon juice
- 2 tsp lemon zest (optional for texture and extra lemon flavor)
- 3/4 cup Swerve (or your preferred granulated sweetener)
- 1/4 cup salted butter
Method
- Beat the butter and Swerve with an electric mixer for about two minutes until light and slightly fluffy—similar to preparing cookie dough.
- Slowly add the eggs and yolks while continuing to mix. Beat for another minute to incorporate. Stir in the lemon juice and, if using, the lemon zest. The mixture may appear curdled at this stage; that is normal.
- Transfer the mixture to a medium saucepan. Cook over low heat, stirring constantly, until the mixture becomes smooth and homogenous.
- Raise the heat to medium and continue to cook, stirring continuously. The curd is ready when it thickens enough to coat the back of a spoon and will leave a slight trail when you run your finger through it.
- If any lumps remain, pass the curd through a fine-mesh sieve into a clean bowl for a silky finish.
- Allow the curd to cool to room temperature, then refrigerate for a few hours to firm up further. Store in a clean jar or jars in the fridge for best flavor and texture.
Tips for Success
- Be patient while the curd thickens. Depending on your stovetop and pan, it can take around ten minutes or slightly longer—continuous stirring helps keep the texture even.
- Using salted butter adds a small, balancing note of salt that enhances the lemon flavor. If you are on a sodium-restricted diet, use unsalted butter and adjust seasoning to taste.
- If you prefer a textured curd, fold in lemon zest. If you want a perfectly smooth curd, strain it and skip the zest. Either approach tastes great—choose based on your preference.
Storage and Shelf Life
Stored in a sealed jar, this lemon curd will keep in the refrigerator for about 1–2 weeks, though it is often eaten much sooner. Note that granulated sugar substitutes such as Swerve can crystallize on the surface; simply spoon off any crystals before serving.
Serving Suggestions
Sugar free lemon curd is versatile: spread it on low carb toast or scones, swirl into plain yogurt, use as a filling for cakes or tarts, or spoon it over fresh berries for a light dessert. A little goes a long way thanks to its concentrated lemon flavor.
