This gooey cheesy potato casserole is perfect as a side dish or on its own as an appetizer. Sweet potatoes and sweet-spicy caramelized onions pair harmoniously, while salty Parmesan cheese with a hint of umami adds a perfect touch. To ensure even cooking, slice the sweet potatoes evenly, preferably using a vegetable peeler.
