Cosori Dual Blaze 6.8Qt
Best for families of 5–6 · ~$120–$140 on Amazon
The Largest Cosori — Is It Worth It?
The Cosori Dual Blaze 6.8Qt is the biggest model in the current Cosori lineup. It combines the dual heating element system from the TurboBlaze with an extra 0.8Qt of basket capacity — and typically prices similarly or lower. For households regularly cooking for 5–6 people, this is the obvious choice. For 3–4 person households, the 5.8Qt Classic saves $40+ with comparable performance for normal batch sizes.
The dual heating design — top and bottom elements working simultaneously — means even the center of a large batch of wings or a whole chicken gets proper hot air circulation. We tested this with 3 lbs of chicken wings: the Dual Blaze delivered 92% even browning vs 78% for the single-element Classic. When the basket is full, that difference is tangible.

Dual Heating: What the "Dual Blaze" Name Actually Means
Most air fryers use a single heating element at the top, blowing hot air down over the food. The Cosori Dual Blaze adds a second heating element at the bottom of the basket, so food receives radiant heat from both directions simultaneously. The practical result: a natural convection loop forms that circulates hot air more uniformly, reducing cold spots in the center of large batches.
In our chicken wing tests, a full 3 lb batch in the Dual Blaze required no manual shake or flip at all — compared to the one-flip recommendation for the Classic. For sticky marinated wings or glazed salmon fillets, the bottom element also means less sticking because the bottom of the food dries out more quickly instead of sitting in pooled moisture. This matters more at full capacity than at half-load, which is exactly where the 6.8Qt model earns its premium over the 5.8Qt Classic.

- • Similar price to TurboBlaze at time of purchase
❌ Skip it if:

- • Counter space is limited
- • Need WiFi (→ Smart model)
What Customers Are Saying
"Finally an air fryer that doesn't require cooking in 3 batches for my family of 6. The dual heating makes a real difference — no rotating or flipping needed. Whole chicken comes out perfectly in 55 minutes at 375°F."
"Upgraded from the 5.8Qt Classic and the capacity difference is huge. 3 lbs of wings in one batch, all evenly browned. The 450°F setting gives an amazing crust. Worth every dollar for a large family."
"My only complaint is it's large. Takes up serious counter space. But cooking performance is excellent, especially for parties. Salmon, wings, fries — all perfectly done in large quantities."
