You can make this with any blue cheese. I have chosen stilton, but if you want a milder flavour, use dolcelatte or gorgonzola instead. This one is a great winter warmer and cooking the vegetables first means you can have this dish on the table in shorter time than a usual gratin. It can also be made in advance and kept in the fridge and needs just 25-30 minutes in the oven when you get home. Serve with kale or another green winter vegetable such as broccoli for a really colourful dish.
Not all eating together or in a hurry?
This dish can be prepared in advance and kept in the fridge for 3 - 4 days. You can also re-heat individual portions.
