I love a good lemon ANYTHING, but Keto Lemon Curd is just pure lemon heaven. Sweet and creamy and tart all in a little spoonful.

  • 6 eggs
  • 1 cup low carb sweetener POWDERED
  • 1/2 cup lemon juice
  • 1-2 tbsp lemon zest
  • 1/4 tsp xanthan gum
  • 4 tbsp butter cut up in small pieces


  • Fill a medium saucepan with 2 inches of water and place over medium heat. Water should be at a rapid simmer.
  • Choose a large heat safe bowl that will fit on top of the saucepan to create a double boiler.
  • First, place eggs, low carb sweetener, lemon juice in the bowl. Then place the bowl on top of the saucepan over the rapidly simmering water.
  • Using a wire whisk continuously whisk the eggs, sweetener and lemon juice together. Turn the heat to high and continuous whisk for 10 full minutes. Whisking should be continuous, but not rigorous.
  • At 10 full minutes of whisking your curd should be thickening up. At this point, continue to whisk and test the thickness of the curd by coating the back of a spoon. Every stove top is a little different, so you may or may not need 1-3 more minutes.
  • When the curd has thickened, remove from the bowl from heat and carefully set on the countertop.
  • Still using the wire whisk, stir in the xanthan gum. Add the butter pieces and stir in until melted.
  • Use curd as a dipping sauce for strawberries and raspberries or use the curd to fill a keto friendly tart shell. This lemon curd is wonderful in my Low Carb Lemon Cheesecake Cups, too.
  • Store in an airtight jar in the fridge for up to a week.


Note...when low carb sweeteners chill they tend to crystalize. This is normal upon chilling and does not affect the taste, just texture. A few quick pulses with an immersion blender to smooth the consistency.
Note...There are 10 servings in this recipe.  Each serving size varies slightly.
