Parmesan cheese is not truly vegetarian, as it contains animal rennet. To make this dish 100% vegetarian, omit the cheese or find a suitable vegetarian substitute made without animal rennet. In supermarkets look for the 'parmesan style hard cheeses' which are suitable for vegetarians.
Made it for xmas practice. love the root veg in the loaf so it's not as heavy as other loaves, was left a big stuck on sides but greens came to the rescue! Warning: Parmesan isn't vegetarian, so make sure to leave it out if any herbivores are at the dinner table - 15 Dec 2011

My family are not vegetarians but we tend to cut out meat two or three times weekly.. Roasting vegetables and adding a crumble topping s a great idea! I tweaked the recipe by substituting celeriac for sweet potato and replacing the seeds in the crumble with a milled seed sprinkle mix (available from Lidl in the UK, there are several varieties). This made the dish more economical and very tasty.. - 14 Nov 2017
