Roasted Onions
Description
This recipe uses large sweet onions cut into half-inch slices without separating the rings. They are coated with a blend of melted butter and balsamic vinegar, then placed in a shallow baking dish where a small amount of water or broth is added to keep moisture during roasting. The onions are seasoned with salt and pepper and roasted at 400°F until soft and browned, with some edges crisping slightly.
The slow roasting brings out natural onion sweetness while the balsamic vinegar adds a subtle acidity and depth. The combination of butter and vinegar ensures a balance of richness and brightness. Depending on the baking dish and onion variety, roasting times can vary; monitoring helps achieve preferred tenderness and caramelization.
Roasted onions can be stored in the refrigerator for up to five days and add flavor to gravies, soups, or stews. Using a ceramic or glass dish may improve roasting results by promoting even cooking and allowing caramelization around the edges.
Ingredients
- 2 large sweet onion 1 ½ -2 pounds
- 2 tablespoons butter melted
- 1 teaspoon balsamic vinegar
- 3 tablespoons water or broth
- ⅛ teaspoon kosher salt or to taste
- ⅛ teaspoon black pepper
Instructions
- Preheat the oven to 400°F.
- Whisk melted butter and balsamic vinegar.
- Peel the onions and cut into ½" slices, do not separate the rings.
- Place the onions in a greased 9x13 baking dish and brush with the butter mixture. It's ok if they overlap a little bit.
- Pour the water into the casserole dish.
- Season with salt and pepper and roast 40-50 minutes or until golden and tender.
Notes
- Use a ceramic or glass baking dish for more even roasting and to develop crispy edges.
- Check onions periodically to roast them to your desired tenderness and caramelization.
- Store leftover roasted onions covered in the fridge for up to 5 days; they enhance gravies, soups, or stews.
