My 4-Ingredient Homemade Lemon Curd Recipe (gluten free + dairy free option)

Here's my lemon curd recipe that only needs 4 ingredients! It's also gluten free, low FODMAP and easy to make dairy free too.


  • 4 lemons, zest and juice of all 4
  • 4 large eggs
  • 225 g butter (a dairy free hard margarine or block if necessary)
  • 320 g caster sugar


  • Crack your eggs into a small/medium saucepan. Off the heat, whisk them together.
  • Add the rest of your ingredients and pop it on a medium heat. Whisk your mixture, allowing the butter to melt and then continue to mix for a further 10 minutes (approx) until the lemon curd starts to thicken slightly. (Don't let it boil)
  • Leave to cool completely before popping it into a glass jars to thicken further in the fridge.
  • This makes about 2 jam jars worth of curd and will last for a few weeks in the fridge. Use it in baking recipes or spread it on toast. Enjoy!


  • If you want to thicken up the lemon curd even further you can simply add a little cornflour when you add the rest of the ingredients, about 2 tsp would be perfect.
