  • 1 tsp dried thyme

  1. Preheat the oven to 375.
  2. Slice the onions and put them into a large bowl. Toss with melted butter, olive oil, balsamic vinegar, thyme, salt, pepper, sugar, and pressed garlic.
  3. Pour onto a large cookie tray lined with foil. Bake in the oven for 40-45 minutes, making sure to toss them regularly. Add more olive oil if you notice any dry or brown spots on the onions.
