Ooni Karu 16 Review
The Verdict
The King of consumer pizza ovens. The first oven to be 'Recommended for Domestic Use' by the Associazione Verace Pizza Napoletana. It is huge, versatile, and engineered to perfection.
Design: Industrial Baking Art
The Ooni Karu 16 is a showstopper. Powder-coated carbon steel shell, glass drop-down door, and a digital thermometer built-in. It looks serious because it IS serious.
The headline feature is the ViewFlame™ technology—basically a glass door that stays clear so you can watch your pizza bake without opening the door and losing heat. It changes the experience from "guessing" to "chef-ing".
Performance: 500°C in 15 Minutes
This is a multi-fuel beast. Burn wood or charcoal for that authentic flavour, or attach the gas burner (sold separately or in bundles) for ease.
- Heat Retention: The insulation is thick. Recovery time between pizzas is minimal.
- Space: The 16-inch opening is a luxury. It makes launching and turning 12-inch pizzas incredibly easy, with room for error.
- Airflow: The ceiling vent gives you detailed control over the flame draw.

Final Conclusion
If you have the space and the budget, this is the upgrade pick.
Compared to smaller 12-inch ovens, the Karu 16 feels like moving from a camping stove to a professional range. It commands a premium price, but it delivers a premium slice.
