This tricolor quinoa and zucchini gratin perfectly combines traditional French baking with modern superfoods. The dish marries the unique texture of multicolored quinoa with tender zucchini, all enveloped in a creamy, golden-brown crust for a satisfying and nourishing meal.
I first created this gratin to use up an abundance of garden zucchini. The tricolor quinoa adds essential nutrients and visual appeal that makes the dish even more attractive. It has since become a weeknight family favorite.
