Oregano-Baked Onions
Oregano-baked onions offer a tender, flavorful side with balsamic and wine infusions, perfect for gatherings or a savory vegetarian main dish.
Ingredients
Instructions
- Place onions upright in a baking dish sprayed with oil.
- Mix balsamic vinegar, white wine, dried oregano, salt, and freshly ground pepper.
- Pour the mixture over the onions.
- Cover and bake in a 425°F oven until onions are tender, about 45 minutes.
Tips & Substitutions
For added depth, consider using red wine vinegar instead of balsamic vinegar for a different flavor profile. If you don't have white wine, vegetable broth can be a great substitute. To enhance the dish, try adding fresh herbs like thyme or rosemary alongside the oregano. Ensure the onions are evenly coated with the vinegar mixture for consistent flavor throughout.
Serving Suggestions
These oregano-baked onions make a delightful side dish, particularly with grilled meats or Mediterranean recipes like grilled chicken. They can also be served over a bed of sautéed spinach and peppers for a vibrant and healthy meal. For an elegant touch, drizzle with balsamic reduction before serving.
