Tandoor high-temperature clay-oven cooking

The tandoor is a cylindrical clay oven that reaches extreme temperatures of 450–500°C (850–932°F), originating in the Indian subcontinent and Persia, and is one of the few cooking vessels that simultaneously delivers radiant, conductive, and convective heat. The oven’s thick clay walls absorb heat from a charcoal or wood fire at the base, then radiate it inward; the hot interior air circulates convectively; and food placed directly on the walls (such as naan) or on skewers (kebabs) receives conductive heat. This triple-heat environment produces rapid charring and smoky flavor while retaining moisture.

Core foods cooked in a tandoor include flatbreads like naan and roti, which are slapped onto the inner walls and bake in seconds; marinated meats such as tandoori chicken and seekh kebabs, threaded on long skewers and suspended vertically; and vegetables like paneer tikka. The technique is central to North Indian, Pakistani, Afghan, and Iranian cuisines. In the Levant, a similar clay oven called the taboon operates at lower temperatures (around 300–400°C) and is used for flatbreads like laffa and for baking stuffed pastries.

Regional variants include the tandir in Central Asia (Uzbekistan, Turkmenistan), often built into the ground or as a freestanding dome, and the tonir in Armenia and Georgia, which is similarly used for bread and meat. In Iran, the tanur is a smaller, portable clay oven used for baking sangak and other flatbreads.

Home approximations typically involve a ceramic tandoor insert for a gas grill or a dedicated electric tandoor, which can reach 300–400°C but rarely match the full intensity of a traditional charcoal-fired clay oven. The tandoor is distinct from an Italian wood-fired pizza oven: pizza ovens are dome-shaped with a door, relying primarily on radiant heat from the dome and a stone floor, whereas the tandoor is open-topped, vertical, and uses direct wall contact for breads and skewered meats.

The tandoor is inherently dietary-neutral: it can cook halal, kosher, vegetarian, and vegan foods depending on the ingredients used. No dairy or animal fats are required for the oven itself, making it suitable for all dietary practices.
