Quick & Easy Keto Lemon Curd

This homemade keto lemon curd is a great little staple to have in your fridge for all kinds of uses.

You can fill low carb tart shells, make a whipped cream lemon parfait, smear it on low carb pancakes, or have it on hand to fill cakes or top cheesecakes. It’s a lot of flavor without many carbs, and the best part is the recipe is quick and easy.

Lemons for curd

You will want to use fresh lemons for this recipe. If you use bottled lemon juice, your final product is going to be bitter and metallic tasting. I have yet to find a bottle of lemon juice that actually tastes like lemon juice. Fresh is how to go with this recipe if you want a beautifully smooth and mellow lemon curd.

Which Sweetners Work best in this recipe?

I used allulose in this recipe. Allulose is my go-to lately because it tastes and bakes very similarly to sugar without a weird aftertaste or texture. Allulose will create a curd that will stay smooth even when cold.

Bocca sweet works very well in this recipe as well.

You can use monk fruit in this keto lemon curd, it will change the flavour profile, but the lemon does help disguise the bitterness a bit.

Erythritol or xylitol will also work, but you will not have a creamy curd after it is refrigerated. Any sugar alcohol-based sweetener (like erythritol or xylitol) will crystalize when cold, especially in recipes where the sweetener is in high concentrations.

Cooking Tips & Tricks

There are a few tips I want to give you for making this keto lemon curd perfect every time. 

1. Use allulose as your sweetener.   Allulose will thicken, get sticky, gooey, and will not crystallize when cooled.  
2. I said it before, but I will repeat it, fresh lemon juice, please.  Add the lemon juice to the allulose and stir.
3. Add two large eggs and two large egg yolks,  2 tablespoons of heavy cream to your pan, and whisk well.   Cook on low heat, constantly stirring until the mixture coats a spoon’s back (about 7-10 minutes).  
4. Add 2/3 cup butter and blend in until melted. 
5. Continue to whisk the lemon curd until it thickens up a tiny bit.
6. Place the curd in a bowl to cool and cover with plastic wrap allowing the plastic wrap to touch the curd’s top. 

Keto Lemon Curd Storage & Serving Suggestions

You need to store the keto lemon curd in the fridge. It will be good to use for up to 4 days. Be sure to keep it covered.
