Celeriac, Potato & Chard Gratin, Vegetarian One-Pan Meal

This may be my favourite vegetarian gratin (gratins often employ seafood) so far. It’s light, flavourful and really healthful thanks to the gorgeous layers of dark leafy greens (a well-known heart-smart ingredient), in this case, Swiss chard and low-starch celeriac. With cheese or without, it’s outstanding in flavour. Even my mom loves it.
