Instructions
- In a small saucepan, whisk together lemon juice, lemon zest, egg yolks, allulose, and a pinch of salt.
- Place the saucepan over medium-low heat and cook, whisking constantly.
- After 5-7 minutes, the curd will start to thicken and coat the back of a spoon.
- Remove the mixture from heat and stir in butter until fully melted and smooth.
- Strain the curd through a fine mesh sieve if you want it ultra silky (optional but worth it).
- Let it cool at room temperature, then transfer to a jar or a bowl and refrigerate until set.
Recipe Tips
- Use fresh lemons. Bottled lemon juice won’t give you the same zingy flavor.
- Cook low and slow. Don’t rush it or you might scramble the eggs.
- Strain for smoothness. A fine mesh sieve gives it that luxe pastry shop texture.
- Store it in glass. Keeps it fresh and flavorful longer.
Ingredient Swaps
- Coconut oil can replace butter for dairy-free. The flavor will be slightly different but still delicious.
- Want it brighter yellow? Add a pinch of turmeric instead of food dye.
- For a creamier finish, stir in 1 tablespoon of heavy cream at the end.
Storage Tips
Store your lemon curd in a sealed glass jar in the fridge for up to 10 days.
It also freezes beautifully. Just scoop into a freezer-safe container and thaw in the fridge overnight.
What to Serve It With
- Crumble a keto sugar cookie on top of it

Really smooth and rich, with just the right lemony flavor. It was easy to make, and I loved it with a slice of almond flour toast. I’ll definitely make it again.
