Begin by heating oil in a large pan over medium heat.

Proceed to add chopped onions and sauté them until they turn translucent and start to brown. This should take about 5-7 minutes.

After that, add minced garlic, ginger, and green chillies to the pan and cook for an additional 1-2 minutes until they release their fragrance.

Then, add chopped tomatoes to the pan and cook for 4-5 minutes until they become soft and pulpy.

Add chicken pieces to the pan and stir them well to coat with the tomato mixture. Cook for 5-7 minutes or until the chicken changes colour.

Next, add ground coriander, ground cumin, turmeric powder, chilli powder, and salt to the pan. Mix them well to combine.

Cook for 2-3 minutes and add 2 tablespoons of water to release the colour of the spices.

Pour water into the pan and stir well. Cover the pan and cook on medium heat for 20-25 minutes, stirring occasionally, until the chicken is fully cooked and the sauce has thickened.

Finally, garnish with chopped coriander leaves and serve hot with rice or naan bread. Enjoy your tasty chicken bhuna dish!
