Keto Lemon Curd
Growing up, one of my staple foods was toast with a plethora of spreads. My mom would always have her pantry stocked with peanut butter, Nutella, and tons of varieties of jams. Being quite the explorative eater, I would love to try out a different jam or jelly for breakfast. While I enjoyed most of mom’s offerings (excluding the marmalade!), my favorite was the lemon curd.
Also known as lemon spread, lemon curd was my absolute favorite thing to add to my toast. I remember sneaking spoonfuls of it during the day and it was definitely the spread that got replaced the most. When I first moved out of home, I started making my own homemade version and when I went keto, it was the first recipe I gave a low carb makeover to.
I’ve been meaning to share a keto lemon curd recipe for quite some time. It’s so easy to prepare and needs just 4 ingredients. I love spreading it over keto bread and low carb baked goods, or even drizzling over desserts!
No sugar and no dairy are needed, but you’d never tell. The texture is thick, gooey, and easily spreadable. It is sweet and full of lemon flavor, without being overpowering.
My sister is the biggest fan of all things lemon and she could not stop eating it- She didn’t believe it was low carb, it tasted too sinful for it!
How to make keto lemon curd?
- Eggs AND egg yolks– A mix of both eggs and egg yolks are used to keep the mixture thick and gooey. Use room temperature eggs, not refrigerated ones.
- Granulated sweetener of choice– Allulose is my preferred keto sweetener, as it melts exactly as sugar does. Monk fruit sweetener and erythritol can also be used, but there is a risk of it being slightly gritty.
- Butter– Unsalted and room temperature butter.
- Lemons– Which will be juiced.
Start by adding the eggs, egg yolks, and sweetener into a small saucepan and whisking together, until combined. Next, place it over low heat, before adding the butter and lemon juice. Whisk continuously until smooth and it begins to thicken. Once it has thickened, remove it from the heat.
Now, strain the lemon curd through a sieve, to remove any potential clumps. Let the lemon curd cool to room temperature, before transferring to a jar and refrigerating it for 2 hours, until chilled.
Tips to make the best low carb lemon curd
- You must use fresh lemon juice, not bottled. The latter often has additives in it that can affect the overall texture of the curd and lack the lemon flavor.
- If you’d like an extra thick curd, continue to let it simmer.
- Be sure to use a sterilized jar or container, to ensure mold does not build up around the edges.
Storing and freezing sugar free lemon curd
- To store: Lemon curd should be stored in the refrigerator, covered. It will keep well for up to 2 weeks.
- To freeze: Place the lemon curd in a freezer friendly jar and store it in the freezer for up to 6 months.
