  1. Ensure that your Ninja air fryer is properly connected to a power source, then open it and remove any racks or accessories inside. This allows for proper air circulation while preheating. [1]
    • If this is your first time using your Ninja air fryer, be sure to remove any packaging and promotional materials. Otherwise, the only accessory you should need to remove is the multi-layer rack.
    • Make sure the crisper plate is inserted into the basket.
  2. First, press the “Power” button to turn the air fryer on. Then, use the “temp” arrows on your air fryer to set your desired preheating temperature. In general, this temperature will be about 400 degrees Fahrenheit (200 degrees Celsius), though it may differ depending on what you’re cooking. Always follow the instructions provided on the package or in the recipe. [2]
    • Note that the fryer basket must be inserted during preheating. Because this is the part that will come in contact with your food, it needs to be properly heated.

  3. After setting the temperature and pressing the “Start” button, your air fryer will begin preheating. It should display the current temperature on its screen. Keep an eye on the display to know when it reaches the desired temperature. This usually takes 3 to 5 minutes. [3]
    • If it helps, you can set a timer for the 3 to 5 minutes by adjusting the “Time” arrows before pressing “Start.”
  4. When your Ninja air fryer reaches the desired temperature, it should beep to indicate that it’s ready. Some models also have a light that turns on when preheating is complete. Once the fryer is properly heated, press “Pause,” then open the basket and place your food inside. Close the air fryer and hit “Start” again to allow your food to cook for the required amount of time. [4]
    • Be sure to adjust the timer by again using the “Time” arrows.
    • When the timer ends, your air fryer should beep and display “End” on the screen.

Do you have to preheat an air fryer?

  1. Regardless of the brand or model of your fryer, preheating ensures your food cooks evenly. Adding your ingredients before the air fryer has properly preheated may negatively impact cooking performance. If you want your food to taste its best, it’s probably better to preheat. [6]
    • Preheating also helps seal in your food’s juices. When the food hits the hot surface, it immediately begins to sizzle, which results in a moist and flavorful meal.
    • It helps ensure food safety, as well. By preheating your air fryer, you help eliminate any potential bacteria in the cooking chamber. This way, you know your food is cooked properly and safely.
  2. When you preheat your air fryer, you already have a hot environment when you put your food in. Since you don’t have to wait for the fryer to reach the correct temperature, your food will cook faster. This is beneficial for when you want a quick bite or you’re in a hurry. [7]

  1. Generally, preheating with oil isn’t recommended, as it can bake into the basket. Not only does this make the basket sticky, but it may give your food a burnt taste. On some extreme occasions, adding oil can also cause the air fryer to overheat. [8]
  2. As soon as your Ninja air fryer finishes preheating, spray it with a cooking spray or olive oil, then add your food. This will help prevent sticking without affecting the quality of your food. [9]

Preheating for Specific Foods

  1. Always follow the preheating instructions provided by your recipe, but in general, it’s recommended to preheat your air fryer to ensure your chicken wings turn out juicy and crispy. Preheat your Ninja air fryer for 3-5 minutes at around 400 degrees Fahrenheit (204 degrees Celsius), then place the chicken wings into the fryer basket in a single layer. [10]
    • Do the same for any breaded foods, like chicken tenders or onion rings. Preheating allows the breading to brown and crisp correctly.
  2. While you generally shouldn’t coat your air fryer with oil before preheating, tossing sweet potato fries in a bit of oil helps them crisp perfectly. Allow your air fryer to preheat, as usual, for 3-5 minutes at 400 degrees Fahrenheit (204 degrees Celsius). Arrange the fries in a single layer. [11]
    • Do the same for homemade french fries. Cooking time may vary depending on the type of potato you use, so again, always follow the preheating and cooking instructions provided by your recipe.
  3. To cook a juicy chicken breast, you’ll typically preheat the air fryer to about 375 degrees Fahrenheit (190 degrees Celsius). Season your chicken breast, then put it in the preheated air fryer for the amount of time specified by your recipe. [12]
  4. Because frozen food has to thaw properly before cooking, it takes a bit longer than fresh or refrigerated ingredients. To ensure your food thaws and cooks evenly, it’s generally recommended to preheat your air fryer a bit longer than usual. If you normally preheat for 3-5 minutes, try preheating for 7-8 instead. Experiment with preheating times to find what works best. [13]

Air Frying Tips and Techniques

  1. If your ingredients are stacked on top of each other, they won’t brown and crisp properly. Try to arrange your food in a single layer on the bottom of the basket. If your ingredients do overlap, shake them halfway through the cook time so they cook more evenly. [14]
  2. Sometimes, the air fryer’s fan may blow small or lightweight pieces of food around, which can create a mess. To prevent this, place a toothpick through the food to keep ingredients together. [15]
    • For example, you might do this for the top piece of bread on a sandwich.
  3. While lining the air fryer basket with foil might make clean-up easier, it can block the air circulation. As a result, your food may cook unevenly. It’s best to avoid using parchment paper or aluminum foil during preheating. [16]
  4. These days, many recipes come with specific instructions for cooking in an air fryer, but some only list the temperatures and cook times for conventional ovens. If this is the case, Ninja recommends reducing the temperature by 25 degrees Fahrenheit (13.8 degrees Celsius) and checking your food frequently to prevent overcooking. [17]
  5. For best results, open the fryer and check on your food while it cooks. This allows you to see when it reaches the desired level of brownness. Use a meat thermometer to check internal temperatures, as well. [18]
  6. Once your cook time is over and your food has properly browned and crisped, remove the basket immediately for best results. If you leave the basket and food in the air fryer, you risk overcooking your ingredients. [19]
  7. If you’re cooking multiple batches of food, let it cool down for a few minutes before you preheat it for the next batch. This helps maintain the air fryer’s performance and prevents it from overheating.
  8. To ensure it continues to work properly, clean your Ninja air fryer after every use. Remove the basket, crisper plate, and any other racks and accessories and wash them with dish soap and warm water. Do not submerge the rest of the unit, and instead wipe it down with a damp cloth. [20]
    • Reader Poll: We asked 194 wikiHow readers how easy it is to clean a Ninja Air Fryer, and 76% of them agreed that it's a struggle to clean . [Take Poll] Try lining the basket with aluminum foil after preheating the air fryer to help make clean up easier!
