Description
Tennessee Onions are a Southern classic made with thick slices of sweet onions, layered in a baking dish, seasoned, and topped with a rich blend of cheeses and butter. As they bake, the onions soften and caramelize while the cheese forms a gooey, golden crust. It’s the perfect comforting side dish that pairs beautifully with grilled meats, BBQ, or even burgers.
