The Ninja air fryer has become a popular kitchen gadget because of its ability to cook food quickly and healthily. By using rapid air circulation, it can deliver that coveted crispy texture with less oil compared to traditional frying methods. However, not all foods work well in this appliance, and knowing what cannot be cooked in a Ninja air fryer is crucial for optimal performance and safety. This article dives deep into which foods are unsuitable for air frying, why they don’t work, and what alternatives you should consider.
How Does an Air Fryer Work?
Before exploring what cannot be cooked in a Ninja air fryer, it’s essential to understand the mechanics behind the device. The air fryer works by rapidly circulating hot air around the food, creating a crispy outer layer while cooking the inside evenly. This method is excellent for smaller, lighter foods that require a quick cook at high temperatures.
However, not every food is suitable for this cooking technique. Foods that are too wet, dense, or large often won’t cook properly in an air fryer. Knowing what cannot be cooked in a Ninja air fryer ensures that you avoid common mistakes and protect your appliance from potential damage.
For example, using oils with low smoke points, like extra virgin olive oil, can cause food to burn and leave an unpleasant taste. Instead, choose oils with higher smoke points, such as avocado or canola oil. Read more about the best oils for air frying.

Common Mistakes: Foods You Should Avoid
Certain foods perform poorly in an air fryer because of their texture, moisture content, or cooking requirements. Let’s take a closer look at what cannot be cooked in a Ninja air fryer and why.
1. Wet-Battered Foods
One of the most common mistakes people make is trying to cook wet-battered foods in an air fryer. Items like tempura or beer-battered fish don’t work well because the high-speed air circulation causes the batter to blow off before it crisps. Instead of frying the batter to a golden brown, the air fryer leaves it soggy, resulting in a disappointing meal.
Solution: To enjoy crispy battered food, use pre-cooked frozen options designed for air fryers. Alternatively, deep-fry or bake freshly battered foods in an oven. If you’re looking for batter-free recipes, check out our list of air fryer-friendly dishes.
2. Cheese-Heavy Dishes
Another category of foods that cannot be cooked in a Ninja air fryer includes cheese-heavy dishes. Foods like grilled cheese sandwiches or mac and cheese can melt and ooze through the basket, creating a sticky mess. The circulating air often causes the cheese to burn or stick to the inside of the fryer, making it difficult to clean and potentially damaging your appliance.
Solution: Stick to pre-fried frozen items like mozzarella sticks if you’re craving cheesy dishes. Otherwise, the oven or stovetop is your best bet for cooking cheese-heavy meals. If you’re looking for more ideas, take a look at our guide to cheese-free air fryer recipes.
3. Raw Grains and Pasta
Many people mistakenly believe that they can cook grains like rice, quinoa, or pasta in an air fryer. However, these items require water for proper cooking and absorption, which an air fryer cannot provide. Attempting to cook raw grains in an air fryer will leave them undercooked, hard, and inedible.
Solution: Cook grains and pasta on the stovetop or in a rice cooker. If you’d like to add a crispy texture, you can always use the air fryer afterward to crisp up already cooked grains, such as in a fried rice dish. For more creative ways to use your air fryer, check out our best air fryer recipes.
4. Popcorn
Popcorn may seem like a great snack for the air fryer, but it is one food that cannot be cooked in a Ninja air fryer efficiently. The fast-moving air blows the kernels around, preventing them from staying still long enough to pop. Additionally, some kernels may get lodged in the heating element, which could damage the appliance over time.
Solution: Stick to using traditional methods such as a stovetop popcorn maker, microwave, or specialized popcorn machine for the best results.
5. Leafy Greens
Light and delicate leafy greens such as spinach, kale, and Swiss chard struggle to cook evenly in an air fryer. The lightweight nature of these greens causes them to get blown around by the circulating air, leading to uneven cooking or even burning.
Solution: Instead of using the air fryer, sauté or bake your greens. If you’re making kale chips, consider weighing the greens down with other ingredients or cooking them in small batches to avoid them blowing around.
Additional Foods to Avoid in a Ninja Air Fryer
6. Large, Bone-In Cuts of Meat
Large cuts of meat with bones, such as whole chickens or pork shoulder, don’t fare well in an air fryer. These cuts cook unevenly because the air fryer cannot distribute heat properly throughout the dense meat. The outside may cook too quickly, leaving the inside raw.
Solution: Use an oven or slow cooker for larger cuts of meat. If you want to use the air fryer, consider cutting the meat into smaller portions like boneless chicken thighs or pork chops that can cook more evenly.
7. Sauces and Marinated Foods
Marinated foods or dishes with a lot of sauce can create a mess in your air fryer. The liquid tends to drip through the basket and can burn onto the heating element, making it difficult to clean and potentially damaging your machine.
Solution: Cook the protein or vegetables in the air fryer first and add sauce afterward to avoid messes and still get a crispy result. For more information on cooking techniques and keeping your air fryer in top condition, visit our air fryer maintenance guide.
8. Foods That Burn Easily
Certain foods, particularly those with high sugar content or that are very thin, can burn easily in an air fryer. For example, thinly sliced sweet potatoes or marshmallows may overcook and burn due to the concentrated heat.
Solution: To prevent burning, monitor these foods closely and adjust cooking times or temperatures. Consider using high-smoke point oils, like avocado oil, to reduce the risk of burning.
Foods That Work Well in a Ninja Air Fryer
Despite the list of foods you should avoid, there are many dishes that work perfectly in the Ninja air fryer. These include:
- Frozen Foods: Pre-cooked frozen items such as fries, chicken wings, and onion rings are made for air frying. Their outer coating crisps up beautifully without the need for additional oil.
- Proteins: Smaller cuts of meat like chicken breasts, pork chops, and fish fillets cook evenly in the air fryer, resulting in a delicious, tender interior with a crispy outside.
- Vegetables: Hardier vegetables like broccoli, carrots, zucchini, and cauliflower roast beautifully in the air fryer. They develop a crispy texture on the outside while remaining tender inside.
- Snacks: Pre-fried snacks like mozzarella sticks and spring rolls come out perfectly crispy when reheated in the air fryer.

Air Fryer Maintenance Tips
Maintaining your Ninja air fryer is crucial to ensure its longevity and performance. Here are a few tips to keep your appliance in top shape:
1. Use High-Smoke Point Oils
As mentioned earlier, low-smoke point oils like extra virgin olive oil can burn at high temperatures, leaving your food with an unpleasant flavor. To prevent this, use oils such as avocado, canola, or grapeseed oil, which can handle the high heat of an air fryer without burning.
2. Clean the Basket Regularly
After each use, make sure to clean the basket and tray of your air fryer to prevent food particles and grease from accumulating. Many parts of the air fryer are dishwasher safe, making cleanup easier. A clean air fryer will perform better and prevent lingering odors or flavors from affecting your future meals.
3. Avoid Overcrowding the Basket
One key to successful air frying is allowing enough space for air to circulate around the food. Overcrowding the basket can lead to uneven cooking, as some areas won’t receive enough heat. For the best results, arrange food in a single layer with some space between items.
4. Use Liners
Consider using parchment paper or silicone liners to help prevent food from sticking to the air fryer basket. These liners also make cleanup quicker and protect the non-stick coating on your air fryer from wear and tear over time.
5. Preheat the Air Fryer
Preheating your air fryer is crucial for achieving optimal results. By allowing the appliance to reach the desired temperature before you begin cooking, you ensure that your food cooks more evenly. Preheating also helps create a crispy outer layer, especially for frozen foods like fries or mozzarella sticks.
Most modern air fryers, including the Ninja models, come with a preheat function, but if yours doesn’t, you can easily preheat it by running it for a few minutes at the desired cooking temperature before placing your food inside.
