6 tablespoons butter

3 tablespoons balsamic vinegar

1/2 cup honey

1/2 bunch fresh thyme

Salt and freshly ground black pepper

4 red onions, halved


  1. Preheat the oven to 350 degrees F.
  2. Combine the butter, vinegar, honey, thyme, salt, and pepper in a small saucepan over medium heat. Bring to a simmer and cook for 1 minute to reduce slightly. Place the onions, cut sides up, in a single layer on a baking pan. Drizzle the butter-vinegar mixture over and roast until soft and slightly caramelized, about 45 minutes.
