The late author Nora Ephron had it right when she said that the ultimate comfort food is potatoes. In her case, it was mashed potatoes. For me, I’m a lover of potato casseroles. I find this variation on potatoes gratin my antidote to tough times and freezing weather. It’s a taste memory that never gets old.
This casserole features sliced potatoes layered with onion marmalade, finished with a garlicky cheese topping. You’ll often find potato recipes with raw onion, but here the onions are tamed into a sweet tangle of deliciousness. The way to make this Seriously Simple is to make up the onion marmalade ahead and then assemble when ready to bake.
