Sheet Pan Scalloped Potatoes with Ham and Peas
This dish is all the best of potatoes au gratin packed into the convenience of a sheet pan supper. There's plenty of crispy, cheese topping that's got a nice element of fresh thyme flavor, the corners and edges maintain a nice crisp, and the potatoes are perfectly cooked in the center. The ham and peas make this a full meal, but not so much that anyone will feel like this is anything but comfort food. When you're adding the cheese sauce, shake the baking sheet a bit to make sure the sauce permeates the potato layers and settles in—this will result in perfect distribution and prevent any overflowing in the oven.
