  • 4 large sweet onions such as Vidalia or large spring onions, halved
  • 1 tablespoons unsalted butter
  • 1 tablespoon Extra-Virgin Olive Oil

  • Preheat oven to 375°F.
  • Peel the onions and slice them in half, stem to root
  • Melt butter and combine in a small bowl with EVOO and oregano balsamic
  • Brush both sides of the onions with the butter mixture and season with salt and pepper
  • Spray (or brush) sheet pan with a thin layer of olive oil (MISTO Oil Sprayer works great)
  • Place onions, cut side down, on the sheet pan and bake in the preheated oven for about 40 minutes or until they’re tender and the edges have caramelized.
  • Once the onions are caramelized, remove them from the oven and sprinkle fresh (or dried) oregano over the top.
