Introduction
Air fryers have kept evolving well past their original “crisp food with less oil” pitch, and the Cosori 9-in-1 TurboBlaze is a good example of how far that evolution has gone. Rather than being a single-function crisping appliance, it’s built as a broader countertop cooking tool, combining nine different functions, a PFAS-free ceramic interior, and a wide temperature range aimed at more precise, even results. This article breaks down what the TurboBlaze actually offers, how its various functions tend to get used in a real kitchen, who it fits best, and a few practical points worth weighing before it takes up space on your counter.
As with the other appliance overviews in this series, this isn’t a ranking exercise or a claim that this is the single best air fryer available — it’s a straightforward look at the specifications and functionality so you can judge for yourself whether it lines up with how you actually cook.
Key Features
9-in-1 functionality. The unit consolidates nine separate cooking modes — air fry, roast, bake, broil, dry, frozen, proof, reheat, and keep warm — into one appliance, which is a meaningfully broader range than a basic air fryer that only handles crisping.
6-quart capacity. This puts it in the mid-to-large range for air fryers, generally suited to cooking for a small to medium household in a single batch, or accommodating larger cuts of food like a small chicken or a full tray of vegetables.
PFAS-free ceramic coating. The interior basket uses a ceramic, PFAS-free coating rather than traditional nonstick chemical coatings, which is increasingly relevant for buyers specifically trying to avoid PFAS-containing cookware in their kitchens.
Wide temperature range (90°–450°F). The low end of this range, starting at 90°F, extends the unit’s usefulness into functions like proofing dough or dehydrating at low temperatures, while the 450°F high end supports more aggressive crisping and roasting than some air fryers with lower maximum temperatures.
Precise heating for even results. This generally refers to the heating element and airflow design being engineered to distribute heat more evenly throughout the basket, aimed at reducing the common air fryer issue of unevenly cooked food, particularly toward the edges versus the center of the basket.
Multiple named functions rather than generic settings. Having distinct dry, proof, and keep warm functions (rather than folding everything into a single “bake” or “air fry” setting) suggests more specific temperature and time programming behind each mode, tailored to that particular cooking task.
120V standard household power. The unit runs on standard 120V household current, meaning no special electrical setup is needed beyond a normal wall outlet.
How It Can Be Used
The air fry function serves as the baseline crisping mode, used for foods like fries, chicken wings, or frozen snacks, relying on hot air circulation to create a crisped exterior with minimal added oil.
The roast setting is generally used for larger cuts of vegetables or proteins that benefit from steady, even heat over a longer cooking period, similar to how a small oven would handle a roasting task.
Bake and broil extend the unit into oven-adjacent territory, with bake suited to items like small casseroles or baked goods, and broil aimed at applying strong top-down heat for browning or finishing a dish.
The dry function is generally used for dehydrating fruits, vegetables, or homemade snacks like jerky, relying on the lower end of the temperature range and extended cooking time rather than the higher heat used for crisping.
The frozen setting is typically tailored specifically to cooking food directly from frozen, adjusting time and temperature to account for the fact that frozen food behaves differently than fresh or thawed ingredients in an air fryer.
The proof function is a less common inclusion for this category and is generally used for proofing bread or pizza dough, relying on a controlled, gentle warmth to help dough rise, an application usually associated with dedicated proofing boxes or ovens rather than typical air fryers.
Reheat and keep warm round out the set, with reheat generally used to restore some crispness to leftovers like pizza or fried food, and keep warm intended to hold already-cooked food at a safe, ready-to-eat temperature until served.
Who It May Be Suitable For
Households wanting one appliance for multiple cooking tasks. Given the nine included functions, this model may particularly appeal to those hoping to consolidate an air fryer, small oven, dehydrator, and proofing box into a single countertop unit.
People who bake bread or work with yeasted dough. The inclusion of a dedicated proof function is a distinguishing feature for this category, making it relevant to home bakers who might otherwise need a separate method for proofing dough.
Those specifically avoiding PFAS in cookware. As with other PFAS-free products in this space, buyers who have made a deliberate choice to avoid PFAS-containing coatings may find this a meaningful differentiator compared to standard nonstick air fryers.
Small to medium households cooking moderate batch sizes. The 6-quart capacity is generally well suited to cooking for two to four people, or preparing a reasonably sized single dish without needing multiple rounds.
People who value consistency across a batch. The emphasis on “precise heating for even results” suggests this model may be a good fit for anyone who has been frustrated by uneven cooking in a previous, more basic air fryer.
Households needing to cook very large batches at once, or those who only ever use the most basic air-fry function without interest in the other eight modes, may find that the extra functionality here goes underused, and a simpler, more affordable air fryer could cover their needs just as well.
Important Things to Consider
Learning curve across nine functions. With this many distinct modes, there’s a genuine learning period involved in understanding which setting suits which type of food, particularly for functions like proof or dry that aren’t part of a typical air fryer’s core use.
Counter and storage space for a 6-quart unit. A mid-to-large capacity air fryer takes up meaningful counter space, and it’s worth measuring available room, especially in smaller kitchens, before committing to this size.
Ceramic coating care over time. While PFAS-free ceramic coatings are generally durable, they can still be sensitive to metal utensils or abrasive cleaning tools, so following manufacturer care instructions is generally recommended to preserve the coating’s performance and appearance.
Not identical to a full-size oven for baking tasks. While the bake and roast functions extend the unit’s versatility, its smaller interior capacity compared to a full oven means it isn’t a complete substitute for larger baking projects or big batches.
Preheat times and function-switching. Multi-function units like this one may require preheating time when switching between very different temperature ranges, such as moving from a proofing task to a high-heat roast, which is worth factoring into meal timing.
Cleaning routine for a nine-function appliance. With more functions generally comes more regular use, and correspondingly, a more consistent cleaning routine is generally needed to prevent buildup, particularly for functions like dry or roast that can leave residue over multiple uses.
Comparison of General Categories
Multi-function air fryers with baking and dehydrating capability, the category this model belongs to, aim to consolidate several small appliances into one unit, offering broader versatility at the cost of a more complex interface and larger footprint compared to basic air fryers.
Basic single-function air fryers focus purely on the crisping function, generally offering a simpler, more affordable option for those who don’t need baking, proofing, or dehydrating capabilities.
Countertop convection ovens offer a larger interior space for baking sheets or bigger dishes and often include many of the same functions (bake, broil, roast), generally at a bigger overall size than a compact air fryer, even a large one like this.
Dedicated dough proofers or proofing boxes are built solely around dough proofing, generally offering more consistent, purpose-built conditions for that specific task compared to a secondary proof function on a multi-purpose appliance.
Dedicated dehydrators are similarly built solely for dehydrating, generally with more surface area and airflow control tailored specifically to that task compared to a general air fryer’s dry setting.
The right choice generally comes down to how many distinct cooking functions a household actually plans to use regularly, available counter and storage space, and whether consolidating several appliances into one unit is worth the added interface complexity compared to keeping single-purpose tools.
