Ingredients Equipment Method Notes

Ingredients
  

  • 2 large onions preferably yellow or sweet onions
  • 1 1/2 cups all-purpose flour for the batter coating
  • 1/2 cup cornstarch adds crispness and lightness
  • 1 teaspoon baking powder creates airy bubbles in the batter
  • 1 1/2 cups vegetable or peanut oil for frying, enough to submerge onion rings
  • to taste salt, pepper, paprika or cayenne seasonings to boost flavor

Equipment

  • Deep fry thermometer
  • Slotted spoon
  • Cooling rack or paper towels
  • Large mixing bowls

Method
 

  1. Peel the onions and slice them into thick rings about 1 cm thick. Keep the rings separated and ready for battering.
  2. In a large mixing bowl, combine the flour, cornstarch, baking powder, and a pinch of salt, pepper, or paprika to flavor the batter. Whisk together until evenly mixed.
  3. Dip each onion ring into the batter, ensuring it’s fully coated on all sides. Let excess batter drip off slightly.
  4. Heat the oil in a deep pan or pot to 180°C (350°F). Use a deep fry thermometer to maintain the temperature, and test with a small batter drop — it should sizzle and float immediately.
  5. Carefully place the battered onion rings into the hot oil in batches, avoiding overcrowding. Fry for about 3-4 minutes, turning occasionally, until they turn a deep golden brown and crispy.
  6. Use a slotted spoon to lift the onion rings out of the oil and transfer them onto a cooling rack or paper towels to drain excess oil.
  7. Let the onion rings rest for a minute to crisp up further, then serve immediately while hot and crunchy, perhaps with your favorite spicy dip or a cold beverage.

Notes

Ensure oil temperature is steady for crispy results. Adjust batter thickness if rings are slipping off or batter clumps. Keep onions cold before battering for better adhesion.
