Step-by-Step Instructions
- Prepare the Onion: Start by peeling the onion. Place the onion root-side down on a cutting board. Using a sharp knife, carefully slice off the top quarter of the onion. Avoid cutting all the way through to the root, as this will be crucial for keeping the onion intact.
- Create the Blossom Effect: With the onion still root-side down, make vertical cuts from the top (where you sliced off the stem) down towards the root, stopping about 1/2 inch from the base. Aim for four even cuts to create four "petals." Then, make two more cuts between each of those, resulting in eight petals. If the onion is very large, you can make even more cuts for a more intricate blossom.
- Season the Onion: Gently spread the petals of the onion apart to help them open up. In a small bowl, whisk together the olive oil, smoked paprika, garlic powder, cayenne pepper (if using), salt, and black pepper. Drizzle and brush this mixture evenly over the entire onion, ensuring it gets into all the nooks and crannies between the petals.
- Preheat the Grill: Preheat your grill to medium-high heat (around 375-400°F or 190-200°C). If you don't have a grill, you can also achieve a similar effect under a broiler or in a hot oven.
- Grill the Onion: Carefully place the seasoned onion, root-side down, directly on the grill grates. Close the lid and grill for approximately 20-30 minutes, or until the onion is tender, the petals are beginning to soften and caramelize, and the outer layers are slightly charred and crispy. The exact time will vary depending on the size of your onion and the heat of your grill. Rotate the onion occasionally to ensure even cooking.
- Make the Dipping Sauce: While the onion is grilling, prepare the dipping sauce. In a medium bowl, combine the mayonnaise, ketchup, Worcestershire sauce, horseradish, garlic powder, smoked paprika, salt, and pepper. Stir until well combined and smooth. Taste and adjust seasonings as needed. For an even richer flavor, you can make this sauce ahead of time and let it chill in the refrigerator.
- Serve: Once the Grilled Onion Blossoms are tender and beautifully caramelized, carefully remove them from the grill using a spatula or tongs. Place the onion on a serving platter. The petals will have naturally parted, creating the blossom effect. Serve immediately with the prepared dipping sauce on the side.

Storing and Reheating Tips
Leftover Grilled Onion Blossoms can be stored in an airtight container in the refrigerator for up to 2 days. The dipping sauce can be stored separately in the refrigerator for up to 5 days.
To reheat, place the onion on a baking sheet and warm it in a preheated oven at 350°F (175°C) for about 5-10 minutes, or until heated through. Be mindful that the petals may lose some of their crispness upon reheating. You can also reheat them gently in a dry skillet over low heat. For the dipping sauce, simply let it come to room temperature or warm it slightly if desired. Freezing this dish is not recommended as the texture of the onion will significantly change.
