Whole spring onions are trimmed and braised low and slow in butter until soft, sweet, and caramelized at the edges. The technique coaxes out natural sugars for a mellow, savory-sweet flavor, making these a versatile side for roasted meats or a topping for grain bowls and toasts.
Ingredients
- 2 bunches spring onions, trimmed and halved lengthwise
- 2 tablespoons unsalted butter
- 1 tablespoon olive oil
- 1 teaspoon sugar
- 1 tablespoon balsamic vinegar
- 1/4 cup vegetable stock
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper, freshly ground
Method
-
Trim the root ends and any tough dark green tops from the spring onions, then halve each one lengthwise and rinse well.
-
Heat the butter and olive oil in a 9-inch skillet over medium heat until the butter melts and foams.
-
Arrange the spring onions cut-side down in the skillet in a single layer and sprinkle with the sugar, salt, and pepper.
-
Cook undisturbed until the cut sides turn golden brown, 5 to 7 minutes.
-
Flip the onions, add the vegetable stock and balsamic vinegar, and reduce the heat to low.
-
Cover and simmer gently, stirring occasionally, until the onions are very tender and deeply caramelized, 20 minutes.
-
Uncover and increase the heat slightly to cook off any remaining liquid, letting the onions turn a deep amber-brown, about 3 minutes.
-
Taste and adjust seasoning with additional salt and pepper, then transfer to a serving dish.
