This vegan mushroom pate freezes really well for up to 3 months. Transfer to a freezer-proof container and cover. Press clingfilm along the surface so that it is touching the pate to stop any ice crystals from forming. You can also transfer into freezer-proof bags and freeze. Squeeze out the air beforehand.
You can also keep this in the fridge for up to 5 days, making it great for advance prep. Especially if you have guests coming round!
