In a mixing bowl combine the ingredients for coating chicken. This is the yogurt, spices, salt (to taste), garlic-ginger paste, green chutney, and lemon juice. Green chutney can be homemade or store bought.
Score the chicken with sharp knife on both sides.
Lather the mixture onto the chicken making sure to thoroughly cover every corner.
Allow this to marinate in the refrigerator for half an hour.
Preheat oven to 425°F.
While chicken marinates prepare vegetables to be roasted alongside chicken. Peel the carrots and halve any large potatoes.
Place the vegetables in a bowl and drizzle with olive oil. Sprinkle with salt, cumin powder, and red chili powder and mix thoroughly coating all over the vegetables.
Once the chicken marinates take it out of the fridge and put it (breast-side up) in an oven-safe dish or roasting pan.
Surround it with potatoes and carrots and stuff with the lemon you juiced earlier. Optionally add a few sprigs of rosemary on top of the chicken.
Lastly drizzle the chicken with olive oil and rub into it thoroughly.
Place the chicken into 425°F preheated oven for 1 hour and 20 minutes (or until juices run clear between leg and thigh) basting every half hour.
Once chicken is done take it out of the oven and allow to rest for 20 minutes before serving.
Enjoy!
