Naan is cooked in a tandoor, from which tandoori cooking takes its name. This distinguishes it from roti, which is usually cooked on a flat or slightly concave iron griddle called a tava. Modern recipes sometimes substitute baking powder for the yeast. Milk or yogurt may also be used to impart distinct tastes to the naan. Milk used instead of water will, as it does for ordinary bread, yield a softer dough. Also, when bread starter (which contains both yeast and lactobacilli) is used, the milk may undergo modest lactic fermentation.

Typically, it is served hot and brushed with some water but in some other cultures such as those in the Indian Subcontinent, they brush ghee or butter. It can be used to scoop other foods or served stuffed with a filling.
