Wine-Roasted Onions

Wine-Roasted Onions turn tender and jammy in the oven, soaking up a lightly sweet red wine glaze that highlights their natural caramelized flavor. They bring rich, savory depth to sandwiches, pastas, and baked potatoes, and shine as a versatile side for roasted meats or hearty vegetarian plates. A sprinkle of thyme adds a fresh, aromatic finish.
