Cooking Functions
The Ninja DZ302 offers 6 versatile cooking functions:
- Air Fry: For crispy results with little to no oil.
- Air Broil: For quick cooking and browning.
- Roast: For tender meats and roasted vegetables.
- Keep Warm: To maintain food temperature after cooking.
- Dehydrate: To gently remove moisture from foods for snacks like fruit chips or jerky.
- Bake: For preparing baked goods.
DualZone Technology
This feature allows for independent cooking in each 5-quart basket. You can use different functions, temperatures, and times for each zone.

Smart Finish
The Smart Finish feature synchronizes cooking times across both zones. This allows two different foods, cooked with different settings, to finish cooking at the same moment.

Match Cook
The Match Cook feature allows you to easily copy the settings from one zone to the other. This is ideal for cooking larger quantities of the same food, utilizing the full 10-quart capacity.

IQ Boost
IQ Boost intelligently distributes power across each basket. When Smart Finish or Match Cook is not selected, this feature optimizes cooking for single-zone use or when cooking different items without time synchronization, aiming for the quickest possible cooking time.
