Do outdoor pizza ovens really cook a pizza in 60–90 seconds?

Yes, when properly preheated to around 900°F. Reviewers across mainstream tech press and pizza-focused subreddits consistently confirm sub-two-minute cook times for thin Neapolitan-style pizzas. Thicker NY-style or pan pizzas need lower temperatures and longer cook times, which is why electric models like the Ninja Artisan that top out around 700°F are gaining traction with that crowd.
