Tandoor Oven: High-Heat Clay-Oven Cooking for Breads and Skewered Foods

A tandoor is a deep, high-temperature oven traditionally built around a clay cooking chamber. Heat from charcoal, wood, gas, or another approved source creates intense radiant and convective cooking, while the hot inner wall can bake flatbreads directly.

How a Tandoor Cooks

The chamber stores and radiates heat while hot air rises through the vertical oven. Skewered meats and vegetables cook in the hot interior, and breads such as naan adhere briefly to the heated wall. Fuel type and oven design vary, so operating methods must match the specific tandoor.

Preheating

A tandoor needs time to heat the clay or refractory mass evenly. Follow the manufacturer’s firing sequence and avoid rapid thermal shock, especially in clay-lined ovens. New or repaired tandoors may require a curing procedure before full-temperature use.

Cooking on Skewers

Use skewers designed for the oven and load food evenly so pieces cook at a similar rate. Secure food so it cannot slide into the fire. Heat varies by depth and position, so learn where each product cooks best and rotate or reposition only with suitable long-handled tools.

Baking Bread

Flatbread dough is shaped and applied to the hot wall using a pad or other traditional tool appropriate to the oven. Removing bread requires specialised hooks or scrapers and confident technique. Hands and arms should never enter the chamber without the protection and method required for the equipment.

Temperature Management

Fuel load, airflow, lid position, and cooking volume influence temperature. A heavily fired oven can char food before the centre cooks; insufficient heat can dry bread or lengthen skewer cooking. Build a stable working condition before service and monitor it throughout the shift.

Ventilation

Solid-fuel tandoors produce smoke, heat, and carbon monoxide and require approved extraction and fire-protection systems. Gas tandoors also require compliant installation and combustion ventilation. Follow local codes and manufacturer clearances.

Burn and Fire Safety

The oven mouth, walls, skewers, and tools can reach extreme temperatures. Use appropriate heat-resistant protection and long-handled tools. Keep combustible items away from the opening and establish a safe area so other staff do not pass directly beside active skewers.

Cleaning and Maintenance

Remove ash safely, clean accessible food debris, and inspect the clay or refractory liner for cracks according to manufacturer guidance. Do not shock a hot clay chamber with water. Maintain burners, gas controls, fuel systems, and ventilation through qualified service where required.

Common Mistakes

• Heating a cold clay liner too aggressively.
• Using skewers that do not secure food properly.
• Reaching too far into the oven without correct tools.
• Operating solid fuel without suitable extraction.
• Applying water to a very hot clay chamber during cleaning.
