This is deliciously comforting food. It makes a great meal on its own, or you can serve is as a delightful and creamy side dish.
What makes a gratin? Look, it’s a baked dish but the standout is obviously a light covering of cheese and/or breadcrumbs. You can use almost any vegetable that can hold its own being baked, which makes potatoes and root vegetables seasonal favourites. But if you’re thinking ‘green’ then leafy spinach is a fantastic option, and it tastes good!
