Easy microwave lemon curd recipe

I’ve been meaning to make my own lemon curd for ages, but it was only after making a pavlova I had the perfect opportunity to use up all the egg yolks leftover. It’s really easy to make, but it’s even easier making microwave lemon curd instead of on the hob.

If you’ve got other citrus fruit you can change the lemons for those – orange or lime both work well. 

With lemon curd it’s best to just use the yolks to keep it thicker and creamier in texture.  As zest creates much of the flavour, you can strain the curd to remove the zest, but I didn’t bother. If you finely zest it, you’re unlikely to notice it when eating.

Whether cooking the curd in the microwave or on the hob, you need to keep stirring regularly. Don’t worry about the egg scrambling. This shouldn’t happen (if it does, straining will help to remove those bits).

With the microwave method, the ease is in just having everything put into a microwavable bowl in one go, and heating it for 3-4 minutes. Just stop and stir every 30 seconds until it’s smooth and thickening. 

You’ll know the curd is ready when it is thick enough to coat the back of a wooden spoon without just dripping off.

Don’t worry that it’s not really thick yet.  The lemon curd will thicken as it cools.

In terms of storage, you’ll need a clean sterilised jar and lid. Washing the jar in a dishwasher is the easiest way to ensure a really clean jar.

The lemon curd will last for around 7 days in the fridge, or 2-3 if keeping out of the fridge.

    1. It’s so easy, and handy if you’ve got egg yolks going spare. I want to try clementine curd next, but I’m the only one in the family who’ll eat it, and I’m meant to be back on my diet, so it might need to wait a while before trying it.
