Performance & Hands-On Testing
When it comes to real-world cooking, both the Ninja DZ550 and the COSORI Pro II claim to deliver crispy, evenly cooked food with little to no oil. But how do they actually perform? We put them through a series of tests to compare their crispiness, ease of use, and cleaning experience.
1. Crispiness Test – Which One Cooks Better?
A great air fryer should deliver golden, crispy, and evenly cooked food every time. We tested both models by cooking French fries, chicken wings, and roasted vegetables to evaluate their crisping ability and consistency.
Ninja DZ550:
- With its dual-zone cooking, the Ninja allows you to cook two different foods at once, but the airflow in each basket is slightly less powerful than in a single-basket design.
- Fries and wings turned out crispy, but we noticed that shaking or flipping was necessary for an even cook, especially with larger portions.
- The Smart Thermometer helps with precision cooking, particularly for meats, ensuring perfect doneness.
- Cooking time was slightly faster than the COSORI due to the high power output.
COSORI Pro II:
- The single, large basket allows for better airflow around food, resulting in more even crisping without needing frequent shaking.
- The 12 preset cooking functions help automatically adjust time and temperature for different foods, making it easier to get great results.
- Fries were extra crispy, and chicken wings had a perfect golden-brown finish.
- While it took slightly longer than the Ninja in some cases, the crisping was more consistent overall.
✅ Winner: Choose the COSORI Pro II for more even crisping, especially for hands-free cooking. However, if you don’t mind manual adjustments, the Ninja is faster but requires more involvement.
2. Ease of Use – Which One is More User-Friendly?
Both air fryers are designed to be user-friendly, but they cater to different types of users:
-
Ninja DZ550:
-
Features manual controls with simple buttons and a digital display.
-
The dual-basket system can be a bit tricky for beginners, as you have to manually set separate cooking times and temperatures for each basket.
-
The Smart Finish feature helps synchronize cooking so that both foods are ready at the same time.
-
Ideal for people who like hands-on control and need to cook multiple dishes simultaneously.
-
-
COSORI Pro II:
-
Features a fully digital touchscreen interface with 13 cooking presets for effortless operation.
-
The VeSync app connectivity allows you to monitor and control cooking remotely via smartphone, Alexa, or Google Assistant.
-
The preset modes simplify cooking, making it more beginner-friendly than the Ninja.
-
Ideal for tech-savvy users or those who want a more automated cooking experience.
-
✅ Winner: Again, if you’re a fan of tech, the COSORI Pro II is great for its intuitive digital controls and smart app integration.The Ninja is simple but requires more manual adjustments, which can be a source of pride if cooking is your passion.
3. Cleaning & Maintenance – Which One is Easier to Clean?
Nobody wants an air fryer that’s a pain to clean, so we evaluated how easy it is to maintain each model after cooking greasy foods like bacon and chicken wings.
-
Ninja DZ550:
-
Each of the two smaller baskets is nonstick-coated and dishwasher-safe, making cleaning straightforward.
-
However, the nonstick coating may wear down over time with frequent use and washing.
-
The dual baskets mean you have twice the surface area to clean, which can be inconvenient.
-
If you only use one basket at a time, it’s a bit easier to clean than COSORI’s single large basket.
-
-
COSORI Pro II:
-
Comes with a larger, single basket, making it simpler to clean with fewer components.
-
The basket and crisper plate are fully dishwasher-safe, making cleanup effortless.
-
The nonstick coating is durable and doesn’t seem to wear down as quickly as Ninja’s.
-
However, the larger basket can be bulky and may take up more space in smaller dishwashers.
-
✅ Winner: Choose the COSORI Pro II for easier cleaning and a more durable nonstick coating. The Ninja’s dual baskets mean extra cleaning effort. But if you have a dishwasher, neither of these should worry you.

How to Use Each Air Fryer
Setting It Up for the First Time
Before using your new air fryer, it’s essential to set it up properly to ensure safe operation and optimal performance. Here’s how to get started with each model:
- Ninja DZ550 Foodi 10-Quart Air Fryer:
- Unbox the air fryer and remove all packaging materials.
- Wipe down the interior and exterior of the baskets with a damp cloth or sponge to remove any dust or residue from the manufacturing process.

- Explore the 13 preset functions and experiment with the settings to get familiar with the controls.
Cooking Tips for the Best Results
Maximize your air fryer’s performance with these tips:
- For Both Models:
- Use small, even layers of food for the best crisping. Overcrowding can lead to uneven cooking.
- Shake or flip your food halfway through cooking for even browning and crisping (especially important for the Ninja’s dual baskets).
- Preheat the air fryer for quicker cooking times and better results.
- Consider using a little oil spray (like olive oil) for extra crispiness, but avoid using too much oil.
- Ninja DZ550:
- The dual baskets let you cook two different items at once, but they need to be monitored and manually adjusted.
- Use the Smart Cook System for precision when cooking meats, such as chicken or pork.
- COSORI Pro II:
- The 13 preset functions are great for beginners—just pick your food type, and the air fryer will adjust the temperature and time automatically.
- The rapid air circulation ensures even crisping without the need for flipping, though occasional shaking is still helpful for some items.
Common Troubleshooting Tips
Air fryers are generally reliable, but sometimes issues can arise. Here are some common problems and solutions:
- Ninja DZ550:
- Uneven cooking: Make sure you shake the baskets halfway through cooking for even crisping. If you’re cooking larger portions, consider reducing the food in each basket.
- Smoke: If you’re cooking fatty foods like bacon, excess grease may drip and cause smoke. Reduce the temperature or add a parchment paper liner to catch grease.
- COSORI Pro II:
- Food is not crispy enough: Ensure you’re not overcrowding the basket. Try using a little oil spray or increasing the temperature for a more crisp finish.
- Basket not fitting properly: Check that the basket is correctly aligned and seated in place. If it’s misaligned, it won’t function correctly.
