Store bought lemon butter spread is not even close to being as good as homemade! This additive free, from-scratch lemon spread is incredibly creamy, tart and sweet. And you only need 4 ingredients and about 20 minutes to make it! Lemon butter is perfect for spreading on toast, scones, cakes, pancakes and more. It also makes the perfect gift in pretty jars.
This lemon spread (lemon butter or curd) is like a little jar of sunshine! With a golden yellow colour and sweet/tart tang, this deliciously creamy spread is perfect for desserts and baking. Or, just slathering over a piece of hot toast or freshly made bread!
- Quick and easy – you’ll only need a bowl, a whisk and a pot and a little over 20 minutes.
- Pantry friendly – this recipe contains only four ingredients- all of them pantry and fridge staples!
- No additives – skip the preservatives and additives found in store bought spreads and try this homemade recipe instead.
What you’ll need
- Lemons – use real, fresh lemons. Store bought lemon juice can be used, but the flavour won’t be the same.
- Eggs – the eggs thicken the lemon butter, just like they would thicken a custard.
- Sugar – to balance the tart lemon flavour.
- Butter – use real butter. The butter makes this spread super creamy and also provides structure to the lemon butter, once cooled.
Step by step instructions
Here is how you make homemade lemon spread. The full recipe and instructions can be found below.
- Place the eggs and sugar together in a glass or other heat-proof bowl and whisk until combined.
- Carefully place the bowl over a pot of gently simmering water. Making sure the bottom of the bowl does not touch the top of the water, whisk in the lemon juice until completely combined.
- While continually whisking, add the butter. As the lemon butter cooks, the butter will melt and incorporate into the mixture. Keep whisking over heat for around 10 minutes, or until the lemon butter thickens to a honey-like consistency.
- Remove from the heat and place the hot lemon butter into clean, sterilised jars. This recipe makes around 3 x 260 gram jars and can easily be doubled for gifting.
Note: Lemon spread should not be made over direct heat. I highly recommend using a double-boiler (or a bowl sitting over a saucepan of boiling water) to cook this recipe. Mixing the ingredients in a pan over direct heat can lead to the curd catching in the bottom of the pan and burning. Separating the curd from any contact with a pan allows it to cook slowly and consistently.
How long does lemon butter last?
When sealed correctly in a sterilised jar, this lemon spread can keep in the fridge for two months. Once opened, store in the fridge and consume within 1-2 weeks.
How can I use lemon butter?
Lemon butter spread has so many uses! It can be used as a filling for tarts and pies, a replacement for jam on pancakes, toast, bread and scones or a filling in lemon curd cupcakes. It can also be used as a topping for pavlova or cakes or a filling in trifle and more! And if you have no self control like me, it’s pretty amazing eaten with a spoon, straight from the jar.
How to thicken lemon curd?
Lemon curd will start to thicken as it cooks. The eggs act as a thickening agent as it heats (this will take around 15-20 minutes, maybe a little longer) and it will continue to thicken further as it cools, due to the butter content.
Which lemons are best?
I personally prefer Meyer lemons, for their intense, sweet flavour and juice content. But any type of lemon will work!
How to sterilise jars
To keep the lemon spread fresh and hygienic, add the hot mixture to sterilised jars immediately after cooking. To seal the jars, twist the lids in place and turn them upside down until the mixture has cooled. Turning them upside down with hot contents should cause the lids to create a seal.
You can sterilise most jars, as long as the seals in the lid are intact. To sterilise jars, place clean, dry jars in an oven at 120 °C for 20 minutes, or place them in a sterilising solution like Miltons, before allowing to air dry. This process can be used for any other spreads, sauces and chutneys.

Homemade Lemon Spread
- 6 large whole eggs lightly beaten
- 1 ½ cups sugar
- 1 cup butter (around 190 grams), cut into cubes
- ¾ cup lemon juice around 4-5 lemons
- Prepare a small saucepan with shallow water and place over low heat until gently simmering.
- In a large glass or heat-proof bowl, whisk the eggs and sugar together until combined.
- Carefully place the bowl over the top of the saucepan, so that it sits over the top. The top of the water should not touch the bottom of the bowl.
- While over the heat, carefully whisk the lemon juice into the egg mixture and continue to whisk.
- Add the butter and continue to whisk the mixture until the butter melts and the mixture becomes smooth and thickens. This will take around 15-20 minutes, maybe a little longer depending on your pot and bowl setup. Once thickened (the consistency of honey), remove the lemon curd from the heat and transfer to sterilised glass jars to cool. The lemon curd will continue to thicken as it cools.
