What do you do when life gives you lemons? Make lemon curd, of course! I absolutely love lemons, in drinks, in desserts, in savory dishes, pretty much any way I can get them.
If you have never made lemon curd before, it's a soft and smooth spread type custard filling often used in tarts and as a filling in pastries.

How to Make Keto Lemon Curd
Whisk in the eggs, then the salt, lemon juice and lemon zest.
Turn the heat up to medium-low and cook for about 6-8 minutes or until it thickens enough to coat the back of a spoon.
The key to this curd coming out smooth and creamy, is to whisk the entire time!
Remove from the heat and cover with plastic wrap, making sure it’s actually touching the curd (to prevent a skin from forming).
Chill in the fridge for about an hour. And that's it! It's just that easy to make your own Keto lemon curd.
Is Lemon Curd and Lemon Pie Filling the Same?
Both lemon curd and lemon pie filling have a delicious lemony flavor but the texture and uses are different. Lemon pie filing uses cornstarch to thicken the mixture and has a thicker texture than lemon curd.
Lemon curd has a more intense lemon flavor and is thickened with eggs and additional butter than what pie filling uses. It can be used for many things including a spread for Keto Pancakes or crepes or used to create these cute little Lemon Curd Thumb Print Cookies.
Are Lemons Keto?
They absolutely are! In fact, lemons are recommended on Keto because of their many health benefits. Where you typically avoid a lot of citrus fruit on Keto, lemons are the exception.
They’re low in sugar, a great source of Vitamin C and contain antioxidants that promote healthy digestion and aid in fluid retention. There’re many other great health benefits discussed in this article on Healthline.
Can I Freeze Lemon Curd?
You sure can. In fact, when frozen in an air tight container it can last up to several months without effecting the taste or quality. That makes it a great make a head recipe for meal prepping desserts in advance.
To thaw, move the container from the freezer to a refrigerator over night. After you have thawed it, you can store it in the refrigerator for a couple of weeks.
