Lemon Curd Recipe | Silky Smooth Homemade Lemon Curd

Jump to Recipe

I'll be honest—if you had asked me years ago what dessert I wanted, lemon probably would've been at the very bottom of the list.

Back then, I was all about chocolate, caramel, peanut butter, and pecans. If there was a chocolate dessert on the table, there wasn't much chance I was reaching for the lemon one.

That all changed as I got older.

The more I baked, the more I experimented, and the more I started appreciating how a bright citrus flavor can completely transform a dessert. Lemon doesn't just add tartness—it adds freshness and balance. Sometimes it's exactly what a rich dessert needs.

Ironically, this recipe was born out of another recipe altogether.

If you've made my Swiss Method French Macarons, you've probably noticed you're left with quite a few egg yolks. I absolutely hate wasting ingredients, so this lemon curd became one of my favorite ways to put those extra yolks to good use.

Made with fresh lemon juice, fresh lemon zest, butter, sugar, and egg yolks, this lemon curd is silky smooth, rich, and bursting with bright citrus flavor.

And before we go any further...

Please don't use bottled lemon juice.

Fresh lemons make all the difference here. The flavor is brighter, fresher, and simply can't be replicated with bottled juice. If you're going to spend the time making homemade lemon curd, fresh lemons are absolutely worth it.

One of my favorite things about lemon curd is how incredibly versatile it is.

I've used it to fill:

• French macarons

• Layer cakes

• Cupcakes

• Pastries

• Tart shells

• Dessert bars

It's also incredible spooned into freshly baked croissants.

Just don't bake it inside the croissants. Bake the croissants first, then pipe the lemon curd inside after they've cooled. Trust me—it's much less messy.

And if you've never had a lemon cream cheese king cake, you're missing out. That bright lemon flavor paired with sweet cream cheese is one of my all-time favorite combinations.

Anytime you want to add a bright, fresh, citrusy finish to a dessert, this lemon curd is an excellent choice.

I hope you enjoy it as much as I do. Happy baking!

Ingredients

(Recipe increased by 1½ times for a larger yield.)

• Granulated sugar — 1½ cups (300 g | 10.6 oz)

• Fresh lemon zest — 3 tablespoons, very finely chopped (from approximately 3–4 lemons)

• Large egg yolks — 9

• Fresh lemon juice — ¾ cup (180 mL | approximately 180 g | 6.3 oz)

• Unsalted butter, cold and cubed — ¾ cup (1½ sticks) (170 g | 6 oz)

Instructions

Step 1 – Prepare the Lemons

Wash and dry the lemons thoroughly.

Using a microplane, finely zest the lemons.

If you have a food processor, you can pulse the zest together with the sugar. This chops the zest even finer while releasing the natural oils, resulting in an even brighter lemon flavor.

Juice the lemons until you have approximately ¾ cup (180 mL) of fresh lemon juice.

Strain the juice to remove any seeds.

Rachel's Tip: Fresh lemons are absolutely worth the extra effort. Please don't substitute bottled lemon juice—it simply doesn't have the same fresh flavor.

Step 2 – Prepare the Egg Yolks

Place the egg yolks into a medium saucepan.

Lightly whisk them until smooth.

This helps aerate the yolks before adding the remaining ingredients.

Step 3 – Add the Sugar

Whisk the sugar into the egg yolks until the mixture becomes slightly lighter in color.

If you didn't process the sugar with the zest earlier, now is the perfect time to massage the lemon zest directly into the sugar using your fingertips before adding it to the egg yolks.

Rachel's Tip: Massaging the zest into the sugar releases the natural citrus oils and dramatically improves the lemon flavor.

Step 4 – Add the Lemon Juice

Gradually whisk in the fresh lemon juice until the mixture is completely smooth.

Step 5 – Cook the Curd

Place the saucepan over low heat.

Cook while whisking constantly.

Continue stirring until the mixture thickens enough to coat the back of a spoon and just begins to bubble.

Do not allow the mixture to boil vigorously.

Rachel's Tip: Low and slow is the key to silky lemon curd. High heat can quickly scramble the egg yolks.

Step 6 – Finish with Butter

Remove the saucepan from the heat.

Immediately add the cold, cubed butter.

Whisk until all of the butter has melted and the curd becomes smooth and glossy.

The finished curd should be silky smooth, even with the tiny flecks of lemon zest throughout.

Step 7 – Store

Transfer the finished lemon curd to a glass storage container with a tight-fitting lid.

I personally like using Pyrex® glass bowls with lids.

Rachel's Tip: Avoid storing lemon curd in metal containers. The acidity of the lemons can react with certain metals and affect the flavor.

I also avoid plastic containers whenever possible. Plastic can absorb odors and flavors from previous foods, and those flavors can transfer into your lemon curd over time. Glass is always my first choice.

Baker's Tips

• Always use fresh lemons.

• Finely chop or process the zest for the smoothest texture.

• Massage the zest into the sugar to maximize lemon flavor.

• Cook over low heat while whisking constantly.

• Remove the curd from the heat as soon as it thickens.

• Cold butter creates a beautifully silky finish.

• The curd will continue to thicken as it chills.

Storage

Store lemon curd in an airtight glass container in the refrigerator for up to 1 week.

Be careful to avoid cross-contamination. For example, if you're filling a cake and your spatula touches cake crumbs, don't place that same spatula back into your storage container. Introducing crumbs or other food particles can significantly shorten the shelf life of the curd.

Lemon curd also freezes beautifully.

Store it in an airtight freezer-safe container for up to 3 months.

Thaw overnight in the refrigerator and stir well before using.
