Grilled Onion Blossom
Nothing says summer like grilled vegetables, and this onion blossom is a standout! With perfectly caramelized layers and a beautiful presentation, it’s as much about the show as it is about the taste. Let’s get started with what you’ll need.

Ingredients
- 1 large sweet onion (like Vidalia or Walla Walla)
- 1/4 cup olive oil
- 1 tablespoon balsamic vinegar
- 1 teaspoon garlic powder
- 1 teaspoon paprika
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- Fresh herbs (optional, for garnish)
Instructions
- Start by carefully peeling the onion. Cut off the top to create a flat surface, but make sure to leave the root intact.
- Using a sharp knife, make cuts downward into the onion, about 2/3 of the way through, creating several petal-like sections. Be careful not to cut all the way to the root.
- In a small bowl, mix together the olive oil, balsamic vinegar, garlic powder, paprika, salt, and black pepper to create a marinade.
- Gently spread the outer layers of the onion apart and brush the marinade generously over the onion, letting it seep into the cuts.
- Preheat your grill to medium heat. If you’re using a grill basket, lightly oil it to prevent sticking.
- Place the onion on the grill, root side down, and close the lid. Grill for about 25-30 minutes, basting occasionally with leftover marinade, until the onion is tender and charred.
- Once cooked, remove the onion from the grill and let it cool slightly. If desired, garnish with fresh herbs before serving.
Serve your Grilled Onion Blossom warm, and watch as everyone digs in! This dish not only tastes fantastic but brings a lovely visual element to your table. Perfect alongside burgers, steaks, or as a standout solo appetizer, your guests will be talking about this one long after the grill has cooled down!
