Cosori Dual Blaze 6.8-Quart Air Fryer Review: The End of “The Shake”?
If you have ever owned an air fryer, you know “The Shake.” Every recipe tells you to stop halfway through, pull out the basket, and vigorously shake your fries or wings to ensure they cook evenly. It is a minor annoyance, but an annoyance nonetheless.
Enter the Cosori Dual Blaze (Model CAF-P583S-KUS). It promises to solve the biggest pain point of air frying by adding a second heating element beneath the basket. Cosori claims this 360-degree heating tech means you never have to shake or flip your food again.
But does it actually work? Does the bottom element burn food? Is it worth the premium price tag over standard models? In this detailed review, we put the Dual Blaze to the test to see if it truly is the best digital air fryer on the market today.

The Game Changer: Dual Blaze Technology
Most air fryers are essentially convection ovens with a single heating coil on the top and a fan that blows that hot air down. This works well, but the bottom of the food is often shielded from the heat, leading to soggy bottoms unless you flip the food.
The Cosori Dual Blaze utilizes what they call 360 ThermoIQ Technology. It features:
- Upper Heating Element: Provides intense direct heat for browning and crisping.
- Lower Heating Element: Provides consistent ambient heat to cook from the bottom up.
- Dual Sensors: Monitors temperature at both the top and bottom to prevent burning.
This setup allows the unit to adjust where the heat is coming from based on the preset. For example, the “Broil” setting pumps heat from the top, while “Bake” balances both. If you are curious about the difference in cooking methods, check out our guide on air frying vs baking.
The only air fryer that cooks from top AND bottom simultaneously. No shaking, no flipping, just perfect results.
Check Current PriceDesign & Usability
Out of the box, the Cosori Dual Blaze looks sophisticated. It ditches the glossy plastic fingerprint magnets of older models for a sleek, matte dark grey finish. It looks premium enough to leave on your counter permanently.
The Interface
The control panel is moved to the top of the unit (a flat glass surface). It is intuitive and responsive. You have 12 functions total: 6 food presets (Chicken, Steak, Seafood, Veggies, Fries, Frozen) and 6 cooking functions (Air Fry, Roast, Bake, Broil, Reheat, Keep Warm).
The Basket
The 6.8-quart basket is massive. It is square-shaped with rounded corners, which offers more usable surface area than round baskets. You can easily fit a 5lb chicken or a large batch of wings. However, because of the bottom heating element, the crisper plate is essential—you cannot remove it to gain extra depth like in other models.
Cooking Performance
This is what matters most. Does the dual heat work?
The “No Shake” Test: French Fries
We loaded the basket with 1lb of frozen french fries and used the “Fries” preset. We did not shake the basket once.
The Result: surprisingly even. The fries at the bottom were just as cooked as the ones on top. While shaking does still improve the result slightly by redistributing the starch, the Dual Blaze produced a 90% perfect result with zero effort. Just be sure to use the best oils for air frying to get that golden finish.
Roasting Chicken
This is where the bottom element shines. Cooking a whole chicken often results in a soggy underside. The Dual Blaze crisped the skin on the back of the chicken just as well as the breast. The temperature sensors were accurate, ensuring the meat was juicy without being overcooked.
Versatility
We also tested baking cinnamon rolls. The consistent bottom heat acted more like a traditional oven, allowing the dough to rise evenly without burning the tops immediately. If you are wondering what else this machine can handle, read our ultimate guide on what you can cook in an air fryer.
Smart App Features (VeSync)
The Dual Blaze connects to the VeSync app via 2.4GHz Wi-Fi. Unlike many “smart” appliances where the app is a gimmick, VeSync is actually useful.
- Remote Start: You can load your food and start the cooking process from your couch.
- Scan-to-Cook: Scan the barcode of frozen foods (like Hot Pockets or pizza rolls) and the app sends the exact time and temp to the fryer.
- Notifications: Get a ping on your phone when dinner is ready.
Comparing this to other top models, like in our Cosori vs. Instant Vortex comparison, the app integration on the Cosori is significantly more polished.
Cleaning & Maintenance
The basket and crisper plate are both coated in PFOA-free nonstick material. Food slides right off. Both parts are dishwasher safe, which is a huge plus.
Because there is a heating element under the basket, you do need to keep the bottom cavity clean. If grease drips through the basket (which is rare due to the design), it could land on the bottom sensor glass. A quick wipe with a damp cloth after cooling is all it takes.
Pros & Cons
- Truly No Shaking: Dual heating elements cook evenly from top and bottom.
- Huge Capacity: 6.8 quarts is plenty for families.
- Precise Temp Control: Dual sensors prevent burning.
- Smart Features: The VeSync app is genuinely helpful.
- Matte Finish: Resists fingerprints and looks great.
- No Preheat Button: It integrates preheating into the cook time, which confuses some users.
- Price: It is more expensive than standard single-element fryers.
- Large Footprint: It requires significant counter space.
Final Verdict
The Cosori Dual Blaze is not just a refresh; it is a genuine evolution in air fryer technology. The addition of the bottom heating element solves the most common complaint about air frying (uneven cooking) and delivers results that are closer to a traditional oven than ever before.
If you are looking for the cheapest option, this isn’t it. But if you want a premium, high-capacity machine that allows you to dump in a bag of fries, press a button on your phone, and come back to perfectly cooked food without lifting a finger, the Dual Blaze is worth every penny.

For most foods, yes! The bottom heating element cooks the underside of food effectively. However, if the basket is completely packed to the brim with fries, a single shake halfway through will still improve consistency, but it is not strictly necessary like in other models.
No. The Dual Blaze heats up almost instantly due to the dual elements. Cosori removed the “Preheat” button specifically because the unit reaches target temperature in seconds.
Yes, you can, but be careful. Because there is a heating element on the bottom, do not place foil under the crisper plate where it could touch the element. Only place foil inside the basket on top of the plate.
Yes, both the main basket and the removable crisper plate are dishwasher safe. The nonstick coating is high quality, so hand washing is also very easy.
Yes, once connected to the VeSync app, you can link it to Alexa or Google Assistant to start, stop, or check the status of your food using voice commands.
