Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
1 cup freshly squeezed lemon juice (about 4–5 large lemons)
1 tablespoon finely grated lemon zest
1 cup granulated sugar (200 g)
3 large eggs
3 large egg yolks
1/2 cup unsalted butter (115 g), cut into small cubes
1 pinch salt
Directions
Prepare the lemons
Wash and dry the lemons thoroughly. Finely grate the zest, avoiding the bitter white pith. Then squeeze enough lemons to obtain 1 cup of fresh juice. Strain the juice to remove seeds and pulp.
Mix the base
In a medium heatproof bowl, whisk together the eggs, egg yolks, sugar, and salt until smooth and slightly pale.
Add lemon
Stir in the lemon juice and lemon zest, mixing well until fully combined.
Cook gently
Place the mixture in a saucepan over low to medium-low heat. Cook slowly, stirring constantly with a whisk or silicone spatula. Make sure to scrape the bottom and sides of the pan to prevent curdling.
Thicken the curd
Continue cooking for about 8–12 minutes, or until the mixture thickens enough to coat the back of a spoon. It should reach approximately 170–175°F (77–80°C). Do not let it boil.
Add butter
Remove the saucepan from heat. Immediately add the cubed butter and stir until completely melted and smooth.
Strain for extra smoothness
For an ultra-silky texture, strain the lemon curd through a fine-mesh sieve into a clean bowl.
Cool
Cover the surface directly with plastic wrap to prevent a skin from forming. Let it cool at room temperature, then refrigerate until fully set. It will continue to thicken as it chills.

Variations
Orange Curd
Replace the lemon juice with fresh orange juice and substitute orange zest for a sweeter citrus version.
Lime Curd
Use fresh lime juice and zest for a sharper, tropical flavor.
Berry Lemon Curd
After cooking, blend in 1/4 cup strained raspberry or strawberry puree for a fruity twist.
Dairy-Free Version
Substitute the butter with a plant-based butter alternative suitable for cooking.
Extra Tangy
Reduce the sugar to 3/4 cup if you prefer a more pronounced lemon flavor.
Storage/Reheating
Storage
Store lemon curd in an airtight glass jar or container in the refrigerator for up to 1 week.
Freezing
Lemon curd can be frozen for up to 3 months. Place it in a freezer-safe container, leaving a little space at the top. Thaw overnight in the refrigerator before using.
Reheating
If needed, gently warm the curd in a heatproof bowl set over a saucepan of simmering water. Stir continuously until smooth. Do not overheat.
FAQs
How do I know when lemon curd is thick enough?
It should coat the back of a spoon and leave a clear line when you run your finger through it.
Why did my lemon curd turn lumpy?
It likely cooked at too high a temperature. Always cook over low heat and stir constantly to prevent the eggs from scrambling.
Can I use bottled lemon juice?
Fresh lemon juice is strongly recommended for the best flavor. Bottled juice can taste flat or overly acidic.
Can I make lemon curd without egg yolks?
Egg yolks help create richness and thickness. You can use whole eggs only, but the texture will be slightly lighter.
Why do I need to strain the curd?
Straining removes zest pieces and any tiny bits of cooked egg, ensuring a perfectly smooth texture.
Can I use salted butter?
Yes, but omit the pinch of salt in the recipe to avoid an overly salty taste.
How long does lemon curd last in the fridge?
It stays fresh for up to one week when stored properly in an airtight container.
Can I use lemon curd as a cake filling?
Yes, it works beautifully between cake layers. For stability, you can pipe a buttercream border to hold it in place.
Is lemon curd supposed to be thick after cooking?
It thickens more as it cools, so don’t worry if it seems slightly loose while still warm.
Can I double the recipe?
Yes, but cook it slowly and stir constantly. Larger quantities may take slightly longer to thicken.
