ONION BAJJI
Jump to Recipe

Bajji is a popular South Indian deep-fried snack, especially loved in the states of Tamil Nadu. It is known for its crispy outside and soft, flavourful inside. Bajji is made by coating slices of vegetables in a spiced batter and then deep-fried until golden and crunchy.

Onion bajji (also called as vengaya bajji in Tamil) is one of the common types of bajji made with onions. Onion bajji is prepared by dipping sliced onions into a thick batter made from gram flour, then frying them in hot oil until golden brown. It is usually served hot with COCONUT CHUTNEY or tomato ketchup.

ABOUT THE RECIPE:

Traditionally, bajji is made with slightly thin round slices of onions. This gives a soft inside with crispy edges. But, onion rings can also be used for this recipe. Each ring has to be separately coated in the batter and fried. Using onion rings gives a much crunchier texture compared to the regular onion bajji.

INGREDIENTS FOR ONION BAJJI:

  • ONION (LARGE SIZE) – 2 NOS.
  • GRAM FLOUR – 1 CUP
  • RICE FLOUR – 1/2 CUP
  • CHILLY POWDER – 1 TSP
  • BAKING SODA – 1/4 TSP
  • SALT – AS REQUIRED
  • OIL – FOR FRYING
Five glass bowls containing ingredients: gram flour, rice flour, chilly powder, baking soda, and salt on a wooden surface.

HOW TO MAKE ONION BAJJI:

  • Peel and wash the onions thoroughly with water. Dry them completely and then slice it. It shouldn’t be too thick or too thin.

PRO TIPS:

  • Onions should be sliced to a medium thickness. If it too thick it stays raw inside, and if it is too thin, it burns quickly and becomes too crispy.
  • Onion rings can also be used for this recipe. Separate each ring from the sliced onion, dip it individually in the batter and add them to the oil.
  • Onions should be completely dry before slicing them. Adding onions along with water might make the batter watery.
  • The batter has to be slightly thick. If the batter is too watery, it won’t hold onto the onions.
