  • Wash onions.
  • Cut onions in half and place in a bowl.
  • Mix other ingredients and pour over onions.
  • Toss to coat.
  • Place onions flat side down in a baking dish and drizzle with any remaining spice mixture.
  • Bake in 450 oven for 30-40 minutes (40 makes them softer and easier to digest). Alternatively, bake at 350 for 1 hour or more to desired doneness.
  • Serve with the skins on and the extra balsamic liquid either drizzled on top or offered on the side.
