How to Preheat OTG: Dos and Don'ts

We all enjoy baking and grilling in OTG, but there are some dos and don'ts to consider on how to preheat your OTG oven.


Read the Manual

Always follow the manufacturer's guidelines for preheating and operating your specific OTG model to get the best results and ensure safety.

Preheat Empty

Preheat the OTG oven empty, without any food inside, to let it reach the desired temperature uniformly.

Opening the Door Frequently

Refrain from frequently opening the oven door during preheating, as it causes temperature fluctuations, affecting cooking times and results.


Don't overcrowd the oven with too many trays or dishes, as it hinders proper air circulation and even cooking.

Using Incorrect Temperature

Avoid guessing the oven's temperature. Rely on an oven thermometer instead for precise temperature readings.

Using Higher Temperatures

Neglecting Cleaning

Failing to clean the OTG oven regularly can lead to smoke, odors, and even fires during preheating.

Using dark-colored or poor-quality bakeware can lead to uneven heating and burnt bottoms.

Ignoring Maintenance

Overlooking regular maintenance and calibration can affect the oven's accuracy and cooking performance.

Placing Food Too Early

Putting food in the oven while it's still preheating may result in undercooked or unevenly cooked dishes.
