Experienced Ooni pizza oven users say an infrared thermometer is a must. This instant-read thermometer measures both the oven’s ambient temperature and the pizza stone temperature. You can quickly and safely know when it’s time to cook.
This infrared thermometer is especially useful because pizza ovens cool some in between pizzas.
Just aim the laser guide at the middle of your pizza stone. When the thermometer reads 752° F, your oven is ready to make the best pizza ever.
