- Cosori's square basket gives approximately 30% more usable cooking space than round baskets of the same stated capacity
- The Cosori Dual Blaze and TurboBlaze use two heating elements and cook 25% faster than standard Cosori models
- Reduce oven temperature by 25 degrees Celsius / 40 degrees Fahrenheit and cooking time by 20 to 25% for standard Cosori models
- If you have upgraded from an older Cosori to a Dual Blaze, expect existing recipes to finish significantly earlier
Cosori Air Fryers: What Makes Them Different
Cosori is consistently one of the top-rated air fryer brands, particularly popular in Australia and the US. Their square basket design (compared to the round basket on many competitors) gives you roughly 30% more usable cooking space for the same stated capacity — which matters when you're trying to cook a decent amount of food without piling it up.
Cosori air fryers run true-to-temperature more consistently than many competitors, which is good news: the standard conversion rule of reducing oven temperature by 25°C works reliably across the Cosori range. The bigger variable is time — and that depends on whether you're using the basic model or the newer Smart/Pro models with improved airflow.

Food-Specific Cosori Cooking Times

The Cosori Preheat Question
Cosori's official guidance varies by model. The basic CP158/CP258 models don't have a dedicated preheat function, but you can preheat manually by running the air fryer empty at your desired temperature for 3 minutes. The Smart and Pro models include a preheat prompt in the app.
For most everyday foods, the difference between preheating and not preheating in a Cosori is minimal — perhaps 1–2 minutes on cooking time. For items where you want an immediate sear (steak, thick-cut chips), preheating makes a more noticeable difference.
Using the Cosori App
Cosori's smart models connect to the VeSync app (iOS and Android), which includes over 100 guided recipes with pre-programmed settings. A practical tip: use these recipe settings as a starting point but treat the times as estimates. Actual cooking time depends on the size and starting temperature of your food, your power supply voltage, and how full your basket is.
Frequently Asked Questions
The most common culprits are an overcrowded basket and not shaking or flipping halfway through. The square basket helps with space efficiency but food still needs airflow around it — if pieces are touching or stacked, the surfaces where they touch won't crisp. Shake the basket firmly at the halfway point for best results.
Yes — the 5.5L Cosori is particularly well suited to baking small cakes, muffins, and brownies. Use silicone baking moulds or small metal cake tins that fit inside the basket. Reduce baking temperatures by 25°C from the recipe and check 5–8 minutes earlier than the recipe states.
Most Cosori models max out at 230°C / 446°F, with the Dual Blaze capable of reaching 260°C / 500°F. In practice, most everyday cooking happens between 160°C and 200°C.
Yes — the basket and crisper plate on most Cosori models are dishwasher safe. However, hand washing extends the life of the non-stick coating. If you do use the dishwasher, place on the top rack. The main unit should never go in the dishwasher.
