Balsamic Roasted Onions Ingredients
To make these Balsamic Roasted Onions, you’ll need a few simple ingredients that combine to create a flavorful and healthy side dish:
- Onions: The star of the dish, onions turn sweet and tender when roasted.
- Butter: Adds richness and helps the onions caramelize perfectly.
- Olive Oil: Enhances the flavor and helps achieve a perfect roast.
- Balsamic Vinegar: Brings a tangy sweetness that complements the onions beautifully.
- White Wine: Adds depth and a slight acidity that balances the balsamic vinegar.
- Sugar: A small amount to help the onions caramelize and enhance their natural sweetness.
- Salt and Pepper: Essential for seasoning and bringing out the flavors.
- Parsley, Thyme, or Oregano: Fresh herbs for garnish, adding color and a final burst of flavor.
Tips and Notes
Here are some helpful tips to ensure your Balsamic Roasted Onions come out perfectly every time:
- Use Sweet Onions: Vidalia or yellow onions are ideal because they roast beautifully and become naturally sweet.
- Don’t Skip the Foil: Covering the onions for the first part of the roasting process helps them cook evenly and retain moisture.
- High-Quality Balsamic Vinegar: Using a good balsamic vinegar will significantly enhance the flavor of the dish.
- Watch the Onions: During the second half of roasting, keep an eye on the onions to prevent burning. They should be golden and tender when done.
- Make Ahead: These onions can be prepared in advance and reheated, making them a great option for meal prep or holiday dinners.
How to Make Balsamic Roasted Onions
- Start by preheating your oven to 425°F. Peel the onions.
- In an ovenproof dish large enough to hold all the onions, melt the butter and combine it with olive oil. Whisk in the balsamic vinegar and white wine, then season with sugar, salt, and pepper.
- Place the onions in the dish, cut side down, ensuring they fit in a single layer. Cover the dish loosely with aluminum foil and roast in the preheated oven for 15 minutes.
- After 15 minutes, remove the foil, turn the onions over, and brush them with the pan juices. Return the dish to the oven, uncovered, and roast for another 10-15 minutes until the onions are tender and caramelized.
- Serve the onions warm or at room temperature, garnished with fresh herbs like parsley, thyme, or oregano.
