Onion paratha is a flavorful Indian flatbread made with a filling of finely chopped onions. The dough is prepared using whole wheat flour, and the onions are mixed with spices like cumin, coriander, and red chili powder. The mixture is then added to the dough and rolled out into a round paratha. It is cooked on a griddle with ghee or oil until crispy and golden. Onion paratha is a popular choice for breakfast or lunch and can be served with yogurt, pickle, or a side of curry.
