Cheesy Tennessee Onions are the ultimate comfort food side dish. Sweet Vidalia onions are sliced thick and layered in a baking dish. They’re seasoned with garlic powder, salt, and oregano, topped with pats of butter, and smothered with a mouthwatering mix of Italian blend, cheddar, and Parmesan cheeses. After baking at 350°F until golden and bubbly, the result is a tender, savory, and cheesy delight that pairs wonderfully with almost any meal.
