Ditch frying and head to the grill to make this onion blossom. Just a few ingredients and a clever cutting technique turn an ordinary onion into a bloomed flower that is then grill-roasted to perfection. The petals turn soft and buttery, with slightly caramelized tips for a delicious flavor. Serve as a fun appetizer with aioli dipping sauce or as a beautiful side dish.

  • 1 onion
  • 1 tbsp. olive oil
  • Salt & pepper, or your preferred seasoning, to taste


  1. Preheat grill to 350.
  2. Peel the outer papery skin off the onion. Gently trim the root end to remove any fibers, being careful not to cut the root end completely off. Trim the stem end to make a flat area.
  3. Turn the onion over with the flat stem side down and cut root to stem to make 16 sections, being sure not to slice all the way to the root though. It will become the base of the onion ‘flower’ from which the ‘petals’ will bloom. Turn onion over to rest on root side, gently separating the petals as needed.
  4. Place onion blossom in oiled cast iron or other grill-safe pan, drizzle with olive oil and sprinkle with seasoning.
  5. Place the pan on the grill with the cover closed, roasting for 40 minutes, or until petals are tender with darkened tips. Remove carefully and serve.
