Step-by-Step Beginner-Friendly Instructions

  5. Pour + wrap: Spoon/pour the butter mixture over onions so it runs down the sides. Wrap foil tightly.
  6. Roast: Place wrapped onions in a baking dish and bake 50โ€“55 minutes until fork-tender.
  7. Optional broil (extra caramelized): Open foil carefully, drizzle a little extra butter/olive oil, then broil 2โ€“3 minutes until golden. Watch closely! ๐Ÿ”ฅ
  8. Serve: Peel away an outer layer, sprinkle a pinch of salt, and pour the foil juices over the onion for max flavor. ๐Ÿ˜‹

Pro Tips

  • Make it a meal: Serve with rice, grilled chicken, steak, fish, or toss the onion into pasta.
  • Storage: Refrigerate leftovers up to 3 days. Reheat wrapped in foil at 350ยฐF until warm.
