If you've never made lemon curd from scratch, prepare to be converted. This is not a "weekend project" recipe — it takes one saucepan, 20 minutes of gentle stirring, and five ingredients that are readily available at the store. The result? A glossy, sunshine-yellow spread that is so alive with citrus flavour it makes anything it touches taste ten times better.
I've tried double-boiler methods, constant-stirring methods, blender hacks. This stovetop approach is silky, most approachable, and optimized for less dishes that I’ve created. The key is cold butter added at the end — it emulsifies the curd into that signature creamy, pourable consistency.
Once you have a jar in the fridge, you'll find yourself reaching for it constantly: spooned onto scones at breakfast, swirled into yogurt, layered into cakes, or honestly just eaten off a spoon over the kitchen sink. No judgment. ;)
Ingredients
Makes approximately 1½ cups (enough to fill one standard jam jar)
4 egg yolks, room temperature
1 cup granulated sugar
⅔ cup fresh lemon juice — about 3–4 lemons (160ml)
zest from 1 lemon, use the same lemon that you're juicing
½ cup cold unsalted butter, cut into 1cm cubes (115g)
A note on ingredients
Egg yolks, not whole eggs. Yolks give a richer, more golden curd with a creamier mouthfeel.
Fresh lemon juice preferred. I’ve made this lemon curd with both bottled lemon juice and fresh lemon juice, and both work. Some people will say that bottled lemon juice lacks the volatile oils that make lemon curd sing, and to squeeze your own. Im here to say use what you have on hand because both work for this recipe.
Cold, unsalted butter, is essential. Adding cold butter at the end, not during cooking, is what creates that silky emulsified texture. Don't skip this step.
Instructions
Combine everything except the butter
Add the egg yolks, sugar, lemon juice, and lemon zest to a medium saucepan. Whisk together until the sugar begins to dissolve and everything looks uniform. Don't worry about it being perfect — it'll come together on the heat.
Cook over medium heat, stirring every few minutes
Place the pan over medium heat. You don't need to stir constantly — every 2 to 3 minutes is fine. You're looking for the mixture to gradually thicken and turn from a pale yellow liquid into a proper custard-like consistency. This takes about 20 minutes. The curd is ready when it coats the back of a spoon and a line drawn through it holds its shape.
Add the cold butter and stir well
Take the pan off the heat. Add all the cold butter cubes at once and stir continuously until every cube is melted and fully incorporated. The curd will turn glossy and noticeably silkier. This is the moment it goes from "good" to "extraordinary."
Jar, cool, and refrigerate
Pour the warm curd into a clean jar (a heatproof glass jar works perfectly - I like using mason jars). Let it cool at room temperature — it will thicken further as it cools — then seal and refrigerate. It keeps for up to 2 weeks in the fridge.
What to do with lemon curd
Honestly, the list is long. Here are the ways I use it most often:
Spread
Lemony Muffins filling
Lemon Tart filling
Swirled into yogurt
Pavlova topping
Thumbprint cookies
Drizzled on pancakes
Stirred into whipped cream
Swirled into a Cheesecake
It also makes a genuinely impressive homemade gift — a small jar wrapped with ribbon is the kind of thing people remember.
Tips for perfect lemon curd every time
Don't rush the heat. Medium is the right temperature. High heat risks scrambling the yolks and you'll end up with lemony scrambled eggs. Patience pays off here.
It will look too thin while it's cooking. Trust the process. The curd sets as it cools, so remove it from the heat when it coats the back of a spoon — not when it's already thick.
Strain for extra smoothness. If you want an ultra-silky curd with no zest bits, pour it through a fine-mesh sieve just before adding the butter. Totally optional but nice for tarts.
Want it tarter? Reduce the sugar to ¾ cup. Want it sweeter? Add an extra 2 tablespoons. The recipe is very forgiving.
Storage & freezing
Lemon curd keeps in a sealed jar in the refrigerator for up to 2 weeks. It also freezes beautifully — pour into a freezer-safe container and freeze for up to 3 months. Thaw overnight in the fridge before using. Give it a good stir once thawed to bring it back together.
Frequently asked questions
How long does homemade lemon curd last?
Stored in a sealed jar in the refrigerator, homemade lemon curd lasts up to 2 weeks. In the freezer, it keeps for up to 3 months.
Can I use whole eggs instead of just yolks?
Yes, though the texture and colour will differ. Yolks produce a richer, creamier, more golden curd. Whole eggs give a slightly lighter result. If substituting, use 2 whole eggs in place of the 4 yolks.
Why is my lemon curd not thickening?
Lemon curd continues to thicken significantly as it cools — it may look too thin in the pan and be perfect once chilled. If it's still very runny after refrigerating for a few hours, it was likely undercooked. It should coat the back of a spoon before you remove it from the heat.
Can I make lemon curd without a double boiler?
Absolutely — this entire recipe uses a regular saucepan directly on the stovetop over medium heat. No double boiler required. Just keep the heat at medium (not high) and stir regularly.
What can I use lemon curd for?
Lemon curd is incredible spread on scones, toast, muffins, and crumpets. It's a classic filling for tarts and layer cakes, a topping for pavlova and cheesecakes, a swirl-in for yogurt and whipped cream, and a beautiful filling for thumbprint cookies.
