Roasted Red Onions with Butter, Honey, and Balsamic Vinegar

Ingredients                         

• 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

Directions

Preheat the oven to 350 degrees F.

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.
