Definitely! We love to make a batch of this and freeze it ready for when we’re making a roast, or even for Christmas dinner. Make the cauliflower cheese as normal, just without the breadcrumbs and extra cheese on top. Once it’s cool you can pop it in the freezer where it should keep for up to three months. When you want to eat it, defrost overnight and then cook for 10-15 minutes on gas mark six or 200°C.
