For the Fritters:

  • 2 large onions, halved, and thinly sliced
  • 1/4 teaspoon salt
  • 1/4 teaspoon ground black pepper
  • 1 tablespoon olive oil
  • 1 cup all-purpose flour
  • 1/2 cup corn starch
  • 1 tablespoon paprika
  • 1 large egg
  • 1/4 cup milk
  • 1/4 teaspoon garlic powder
  • vegetable oil for frying

For the Aioli:

  • 1/2 cup mayonnaise
  • 1/4 teaspoon fresh ginger, grated
  • 1/4 teaspoon garlic, minced
  • 1/4 teaspoon dried red chili flakes


  • In a large cast-iron skillet, bring the olive oil to medium low temperature, and add the onions, salt and pepper
  • Saute, stirring occasionally, until the onions have softened, wilted, and have turned a deep brown colour (be careful to keep an eye on the heat; you don't want to burn the onions - nice and slow is the way to go!)
  • Once the onions are caramelized, transfer to a small bowl to cool completely
  • In the meantime, prepare the spicy aioli dipping sauce be combining the mayonnaise, ginger, dried red chili flakes, and garlic in a small bowl - cover and place in the refrigerator
  • Now that the onions have cooled, prepare the batter for the fritter.
  • In a large bowl, add the flour, cornstarch, paprika, egg, milk, salt, pepper, and garlic powder. Whisk until smooth and frothy
  • Add the cooled caramelized onion to the flour mixture and lightly stir to combine
  • Heat the vegetable oil in a cast-iron skillet
  • Using metal tongs, gently pick up a small portion of the onions from the batter - aim for tablespoon size, and gently place in the hot oil
  • You can fry three or 4 at the same time, but don't overcrowd the pan
  • After two minutes, gently lift one of the fritters and check for a deep brown colour; if done, flip to cook the other side, otherwise, leave to continue frying for another minute
  • Remove fried onion fritters and place on a paper towel-lined platter
  • Continue frying until all onions/batter have been used
  • Serve the onion fritters at room temperature with the chilled aioli dipping sauce
