Description
These roasted balsamic onions are tender, savory, and coated in a sweet and tangy glaze that highlights their natural flavor. Perfect as a versatile side dish, they pair beautifully with roasted meats, vegetable dishes, or holiday spreads.
Ingredients
- 1 pound small onions
- 3 tablespoons balsamic vinegar
- 2 tablespoons olive oil
- 1 tablespoon honey
- 1 tablespoon Dijon mustard
- 1/2 teaspoon dried thyme
- 1/2 teaspoon kosher salt
- 1/4 teaspoon freshly ground black pepper
Instructions
- Bring a medium sized pot of water to boil. Add cold water to a bowl with several ice cubes. Preheat the oven to 400°F (200°C).
- While the water is coming to a boil, whisk together the balsamic vinegar, olive oil, honey, mustard, thyme, salt, and pepper.
- Add the whole, unpeeled onions to the boiling water and let boil for 2 minutes. Remove them from the pot and add to the bowl of iced water. Let cool for 2 minutes.
- Remove the onions from the water. Slice off the root end of each onion and gently squeeze to push the onions out of their skins. If you have any onions on the larger size, you can cut them in half.
- Put the onions in a small baking dish. Pour over the balsamic glaze and toss to coat. Roast in the oven for 20 minutes, then toss the onions around in the glaze again, and roast for another 20 minutes or until cooked to your liking. Serve warm.
Notes
Smaller onions (like pearl) will cook a bit faster. Start checking them for doneness at 30 minutes. Larger onions may need a little longer than 40 minutes.
The best way to tell if the onions are done cooking is to give one a try. The exact cooking time varies depending on the size of your onions. Smaller onions, like pearl onions, will cook faster.
If using fresh thyme, use 1 tablespoon of leaves.
If deciding to cook the onions for more than 40 minutes, check them at 5 minute intervals to avoid burning the glaze. If the glaze looks like it's on the verge of burning but the onions aren't done cooking, add a small splash of water to the bottom of the dish.
