  • Preheat your oven to 400 degrees.
  • Line a rimmed baking sheet with aluminum foil and coat foil with cooking spray or oil.
  • Slice your onions in half crosswise so that the stem or root is at the top or middle of each onion half.
  • Using a small, sharp knife slice an x into each onion near the root or stem. This will allow steam to escape from the onion as it bakes inside your oven.
  • Using a brush, coat bottom of onions with olive oil and place on top of baking sheet, cut and olive oil side down.
