Microwave Keto Lemon Curd

Making homemade Lemon Curd couldn’t be easier than using this quick microwave method! This tart, refreshing spread is excellent on low carb pancakes, toast, chaffles, as a topping for ice cream, cottage cheese or yogurt, as a filling for tarts, thumbprint cookies or between layers of a cake. My grandmother loved it on peaches. Eating it straight from the jar by the spoonful is another way! It also makes an excellent gift to share with your keto friends and family. The list could go on and on…

Microwave Keto Lemon Curd

Makes 3/4 cup (12 servings)

1/4 cup unsalted butter, very soft or melted and cooled

1/4 cup powdered erythritol

1/4 cup allulose (or Bocha Sweet)

1/2 teaspoon lemon zest

1/2 cup fresh lemon juice (it’s important that it be fresh, not bottled!)

1 large egg + 1 egg yolk

1/4 or 1/2 xanthan gum (*see note below)

4-6 drops monkfruit extract

1/8 to 1/4 teaspoon stevia glycerite (or more monkfruit extract to taste)

1. Whisk together the butter, powdered erythritol, allulose, lemon zest, lemon juice and egg in a large microwave-safe bowl. (The mixture will expand considerably during the cooking process, so it’s best to use a large bowl to prevent any overflow.)

2. Microwave on high in 45 second intervals, stopping between intervals to whisk thoroughly, until the mixture has thickened and coats the back of a spoon, about 4-5 minutes in total. (The mixture will thicken more once cooled.) 

3. After cooking, add the xanthan gum and whisk vigorously until incorporated and dissolved. Add the stevia glycerite and monkfruit extract to taste.

4. Using a fine mesh strainer, strain the warm mixture into a clean bowl, using a rubber spatula to press the curd through the strainer. Discard any remaining solids. Cover the surface with plastic wrap, pressing down to make sure the wrap touches the top of the curd to prevent a skin forming. Refrigerate until set, overnight is best. Remove from the refrigerator and, if desired, spoon into a glass jar or other airtight container for storage. Keep refrigerated. Can be stored for 7-10 days.

Note: If you’ll be using this Lemon Curd as a filling between cake layers or for a tart, use the 1/2 teaspoon amount of xanthan gum for the extra thickening power it provides. If serving as a spread or sauce, the 1/4 teaspoon measurement is adequate.
