A crispy and crunchy fried onion bloom served with a tangy and spicy dipping sauce, perfect for snacks, parties, or casual get-togethers.

Ingredients

Scale
  • 2 medium large yellow onions, peeled and separated into petals
  • 1 cup all-purpose flour (120 g)
  • ½ cup cornstarch (60 g)
  • 1 teaspoon baking powder
  • 1 cup cold sparkling water (240 ml)
  • 1 teaspoon salt, plus extra for seasoning
  • ½ teaspoon ground black pepper
  • Vegetable oil for deep frying (peanut or canola oil preferred)
  • For the Spicy Dipping Sauce:
  • ½ cup mayonnaise (120 g)
  • 2 tablespoons sriracha sauce (adjust to taste)
  • 1 tablespoon fresh lime juice
  • ½ teaspoon garlic powder
  • ¼ teaspoon paprika
  • Salt to taste

Instructions

  1. Carefully peel the onions and separate into individual petals, keeping them as intact as possible. Place petals in a bowl of cold water with a pinch of salt and soak for 15 minutes. Drain and pat dry thoroughly with paper towels.
  2. In a mixing bowl, combine all-purpose flour, cornstarch, baking powder, salt, and black pepper. Slowly whisk in cold sparkling water until smooth, thick batter forms that can coat the onion petals evenly.
  3. Pour enough vegetable oil into a large deep frying pan or Dutch oven to submerge the onion bloom (about 3 inches deep). Heat oil to 350°F (175°C).
  4. Thread the onion petals back together carefully using a skewer or fingers to create a flower shape. Lightly dip the entire bloom into the batter, coating every petal.
  5. Gently lower the battered onion bloom into the hot oil. Fry for 4–5 minutes, turning occasionally with tongs to ensure even golden crispiness. Avoid overcrowding the pan; fry one at a time if necessary.
  6. Remove the onion bloom with a slotted spoon and place on a cooling rack lined with paper towels. Immediately sprinkle with salt while still hot.
  7. While frying, whisk together mayonnaise, sriracha, lime juice, garlic powder, paprika, and salt in a small bowl. Adjust spiciness or acidity to taste.
  8. Serve the crispy onion bloom on a plate with the spicy dipping sauce on the side. Garnish the sauce with chopped green onions or fresh herbs if desired.

Notes

Keep oil temperature steady at 350°F (175°C) to avoid greasy or burnt batter. Dry onion petals thoroughly before battering to prevent oil splatter. Fry one bloom at a time to maintain oil temperature. Serve immediately for best crispiness. Reheat leftovers in oven at 375°F (190°C) for 5–7 minutes; avoid microwaving.
