Cashew cheese sauce

One of the first recipes I learnt when I left home was how to make cheese sauce. It was just so useful. But not that easy as first I had to master how to make a roux, add the milk correctly and avoid lumps.

Of course, once I went dairy-free, this trusty cheese sauce was off the menu. But then I discovered cashew cheese sauce using nutritional yeast and a little dollop of mustard to get the right flavour. OK, it’s not exactly like ‘normal’ cheese sauce, but it does the job perfectly well. And it’s really easy – no more lump challenges or burning flour and butter!

This recipes uses the basic cashew cream plus some extra savoury flavours. I like a little Dijon mustard in mine, but if you can’t tolerate it, then leave it out. The same goes with the garlic granules, although I do suggest trying them as the flavour is definitely enhanced by them.

It really is very simple – here’s a little video I made to show you how.


This yummy cashew cheese sauce can be used for pasta, vegetables or pouring over dishes like this delicious tomato and roasted aubergine gnocchi bake. It does dry out a little when baked in the oven or heated in a pan, so don’t make it too thick if you like lots of sauce with your meal.
