Easy 5 minute Microwave Lemon Curd

Sharing is caring!

My Easy 5 Minute Microwave Lemon Curd recipe uses only four ingredients. Deliciously silky smooth, tangy from fresh lemons and yet sweet and so buttery. Homemade lemon curd this decadent is irresistible !


Perfect for topping cheesecakes and as a cake filling – we absolutely love it spread on toast and homemade scones. Plus, I always make lemon curd to go in my Homemade Belgian Buns.

This recipe is quicker than the stovetop and there’s no double boiler, constant whisking or worrying about scrambled eggs. You don’t even need to strain it.

The secret to the best microwave lemon curd is the whisking of eggs and sugar at the start to prevent curdled eggs. The whisking helps break up the eggs and dissolve the sugar before you add the rest of the ingredients.

Then it’s a few 1 minute microwave bursts with a good old whisk in between. Finish off with a couple of 30 second bursts until the curd is nice and thick and you’re all done.

Once you’ve made lemon curd in the microwave, you won’t ever need to buy lemon curd from the shop.

This ridiculously easy lemon curd recipe makes four pots which will keep in the fridge for up to two weeks.

The recipe is easily halved if you want to make just two pots. Chances are though, once you’ve tasted it, two pots might not be enough.

What equipment do I need ?

  • Fine Microplane grater – makes fine shreds of lemon zest which helps achieve a smooth lemon curd.
  • Citrus juicer – a juicer makes sure you get as much juice out of the fruit as possible.
  • Large balloon whisk – I use my Oxo Good Grips balloon whisk. The handle is comfortably shaped from soft non-slip material so you can easily make an efficient job of whisking.
  • Large microwavable bowl – I used my trusty Pyrex bowl which has plenty of room for whisking.
  • Large jug – this is optional but it will make the process of potting up your lemon curd much easier.
  • Jam funnel – definitely something I wouldn’t be without as it saves a lot of mess and waste.
  • Sterilised jam jars – at least 4 x 240ml jars with lids.
  • Digital thermometer – I use my Thermapen as a quick and easy way to check the setting point of curds. You’re looking for between 82C and 84C.

What ingredients do I need ?

6 eggs in a bowl, a pack of butter, a bowl of caster sugar, 2 lemons and 2 half lemons on a work top.
  • Lemons – both the juice and the zest is used. Choose unwaxed lemons if you can. If you can’t get hold of unwaxed lemons, give the lemons a good scrub to remove any wax.
  • Eggs – I used large eggs at room temperature. To prevent curdling it’s important to make sure there are no big temperature changes when adding ingredients to eggs.
  • Sugar – I used caster sugar as it dissolves more quickly into the eggs.
  • Butter – I’ve used salted butter which gives the curd a more balanced flavour.

How to make Easy 5 minute Microwave Lemon Curd

The recipe is easily halved to make just two pots and will take a minute to a minute and a half less time.

  • Zest and juice lemons.

  • Add the melted butter and whisk again.
  • Pop the bowl in the microwave for up to four one minute bursts, whisking between each burst. The cooking time may vary depending upon the power of your microwave – my microwave is 1000 watts.
  • You will see the lemon curd start to thicken after two or three bursts. It will also start to change colour and become bright and glossy.
  • Now it’s time to finish with two or three thirty second bursts. Remember, microwaves are very powerful and in this final stage you don’t want to overcook the curd.

FAQs

Why is my lemon curd not thickening ?

Usually it’s because the eggs in the mixture haven’t cooked enough to thicken it.
Lemon curd will thicken as it cools, so check when cool. If it’s still runny when cooled, pop it back in the microwave for a couple of one minute bursts.
A failsafe way to check your lemon curd is done, is to check the temperature with a digital thermometer. It should read between 80 °C / 176 °F and 84 °C / 183 °F

How long does Lemon Curd last ?

Lemon curd will keep for up two weeks in the fridge. I have kept a jar for three weeks and it was still good to eat.
You can of course freeze some of your lemon curd if you think you won’t use it up in time.

Can you freeze Lemon Curd ?

Yes you can ! Lemon curd freezes well. It will keep for up to three months in the freezer.
Freeze in small batches. Put into freezer safe containers or bags. Freeze as soon as it’s cooled down.
If using containers, a piece of baking parchment over the curd before putting the lid on prevents a skin forming.
To defrost, place your frozen lemon curd in the fridge to thaw overnight.
Once thawed give it a thorough stir before using.A freezer container filled with curd with a piece of baking parchment being peeled off and a freezer container of lemon curd being stirred.
