If you struggled to like turnips as a child, consider trying this grown-up version in which the earthy root vegetable is complemented by Gruyere’s assertive cheesiness. Thinly-sliced turnips become meltingly tender in a cheesy cream sauce served underneath a lid of golden, crispy breadcrumbs. If you’d like to further contrast the sauce’s richness, a pinch of cayenne pepper sprinkled in along with the thyme and garlic would add a faint blush of piquancy without being outright spicy. Wait a few minutes before slicing and serving the gratin to help the liquid set, which ensures it stays creamy, not watery.
