Many foods can cause problems in an air fryer. Experts warn against using wet batters, leafy green vegetables, large pieces of meat, baked goods, and popcorn kernels. These foods can pose safety hazards, such as smoke or fire, or even damage your air fryer. Some foods should absolutely never be cooked in an air fryer because they can pose a potential risk of electric shock. These foods often won’t cook thoroughly or will become a mess. Each risk is explained in detail below.
Key Takeaways
- Avoid wet batter foods in an air fryer. They can drip and create a mess, leading to soggy results.
- Do not cook leafy greens in an air fryer. The strong airflow can burn them and cause uneven cooking.
- Large cuts of meat do not cook well in an air fryer. They block airflow and can lead to undercooked centers.
- Baked goods struggle in an air fryer. They need steady heat to rise properly, which an air fryer cannot provide.
- Popcorn kernels should not be used in an air fryer. They require high pressure to pop, which the appliance cannot achieve.
Wet Batter Foods :Foods that don’t cook well in an air fryer
Why Wet Batter Fails
Food coated in a wet batter will not cook well in an air fryer. Air fryers use hot air to heat food, but they cannot dry a wet batter like frying. Frying involves immersing food in hot oil, which absorbs moisture and makes it crispy. Air fryers use very little oil and rely on airflow for heating. Wet batter tends to drip to the bottom of the basket, preventing the food from reaching a golden-brown crisp. If the batter is too wet, the food will become soggy instead of crispy. Steam buildup can cause food to splatter or dry out quickly. Excess moisture can also impede airflow, resulting in uneven heating.
The AOKAI high-performance air fryer is powerful but not suitable for cooking food coated in wet batter. Its heating and airflow are best suited for dry or lightly battered foods. Wet batter, soups, and stews will not achieve the desired texture and are prone to problems during cooking.
Common Issues with Wet Batter
Many people say they have problems when they try to cook wet batter foods in an air fryer:
- Wet batter can drip through the basket and make cleaning hard.
- Sauces and liquids from soups or stews can hurt the air fryer if they leak through the holes.
- Beer-battered fish and thickly coated foods can make a big mess and leave puddles at the bottom.
- Grease from wet batter can splatter, which is not safe and makes cleaning harder.
Note: Air fryers do not work well for soups, stews, or foods with wet batter. These foods will not cook right and can make a mess that is hard to clean up.
Leafy Greens: Things You Should Never Put in an Air Fryer

Why Leafy Greens Don’t Work
Leafy greens like spinach and kale do not cook well in an air fryer. These foods are very light. The strong airflow inside the air fryer can blow the leaves around. This movement causes the greens to cook unevenly. Some pieces may stay raw while others burn quickly. The hot air can dry out the leaves and make them crispy in some spots, but most of the time, the greens turn brown and bitter.
People often want to make healthy snacks with leafy greens. They may try to make kale chips or crispy spinach. The air fryer seems like a good choice because it cooks with less oil. However, the results often disappoint. The leaves do not stay in place. They can get stuck in the heating element or block the airflow. This can lead to smoke or even a burning smell.
Problems with Air Frying Greens
Air fryers are best suited for cooking heavier, less mobile foods. Leafy greens, however, are too light and tend to tumble in the air, resulting in uneven heating and a less crisp texture. Even high-end models like AOKAI cannot solve this problem. The design of air fryers makes controlling the cooking process of leafy greens difficult.
Here are some common problems when trying to cook leafy greens in an air fryer:
- The leaves fly around and may burn.
- The greens cook unevenly, with some parts raw and others overcooked.
- Small pieces can get stuck in the fan or heating element.
- The air fryer may produce smoke or a burnt smell.
Tip: For best results, use the air fryer for foods that are heavier and less likely to move around. Save leafy greens for other cooking methods, such as sautéing or baking.
Large Cuts of Meat: Foods You Should Never Cook
Why Large Meats Are a Problem
Large pieces of meat, such as whole chickens or large cuts of roast beef, are not suitable for air fryers. Their large size obstructs the flow of hot air. When hot air cannot reach every part of the meat, the outside cooks faster than the inside, resulting in dry edges and an undercooked center, and potentially uneven coloring. Air fryers are best suited for cooking small pieces of meat, allowing for free airflow.
Cooking experts have found that large pieces of meat often result in uneven cooking. Air fryers cannot heat the thickest parts of the meat evenly, causing some areas to remain raw while others are overcooked. Even high-quality air fryers exhibit this problem. The design of the frying basket and the way the internal airflow occurs inherently make it difficult to cook large pieces of food evenly.
Risks of Cooking Large Cuts
Cooking large pieces of meat in an air fryer can be risky. If the center of the meat isn’t fully cooked, harmful bacteria can survive, leading to food poisoning. Overcooking the edges not only results in a poor texture but also leads to waste. Furthermore, air frying large pieces of food may consume more energy and take longer, with less than ideal results.
For large pieces of meat, a traditional oven or grill is recommended. These tools can easily handle large pieces and ensure even heating. Even professional-grade air fryers like AOKAI are better suited for cooking smaller pieces of meat. To ensure safe and delicious cooking, it’s recommended to cut the meat into smaller pieces before using the air fryer.
Tip: Avoid putting raw rice and other grains in the air fryer. These foods need water to cook and will not soften in dry heat. Save them for boiling or steaming.
Note: Large cuts of meat and raw rice and other grains are not good choices for air frying. Choose foods that fit well and allow air to move around for the best results.
Baked Goods: Things You Shouldn’t Cook in an Air Fryer

Why Baked Goods Struggle
Baked goods often fail in air fryers. Cakes, cookies, and muffins require a stable temperature and even airflow to rise and set. The rapid airflow inside an air fryer causes the batter to dry out before it’s fully cooked, resulting in hard edges and a mushy center. Many people find that food baked in an air fryer doesn’t look or taste as good as desired. Air fryer baskets are smaller than those in regular ovens, so they can’t accommodate large baking trays or pans, limiting the amount of food that can be baked at once. Some foods, such as cheeses, may melt unevenly and drip from the basket’s holes, making a mess and difficult to clean.
The AOKAI air fryer is suitable for a variety of foods, but it’s best suited for foods that need to be crispy or reheated. Baked goods require more space and gentler heat. Air fryers are not designed to achieve the same results as traditional ovens. Those who want to bake cakes or cookies should use an oven for the best results.
Common Baking Issues in Air Fryers
Many people experience problems when baking in an air fryer. Uneven bakes are common because the hot air does not reach every part of the food equally. Some parts may burn while others stay raw. Cheesy items, like cheese-filled pastries, can bubble over and stick to the basket. This makes cleaning harder and can affect the taste of other foods cooked later.
Here are some common issues with baking in an air fryer:
- Cakes and cookies may dry out or burn on the outside.
- Cheesy items can melt and drip, causing sticky messes.
- The small basket size limits the amount of food that can be baked.
- Foods may not rise or set as they would in a regular oven.
Tip: For best results, use the air fryer for foods that need crisping, not for baking cakes or cookies. Save baked goods for the oven and enjoy better texture and flavor.
Popcorn Kernels: Foods to Avoid in Air Fryer
Why Popcorn Doesn’t Pop
Popcorn kernels require a special cooking method to pop. They need rapid, even heating to build up enough pressure inside each kernel. Air fryers use convection heating, circulating hot air within the basket. This method cannot produce the rapid volumetric heating required for popcorn kernels. Scientists explain that the pressure inside a corn kernel must reach approximately nine atmospheres to pop. The heating method in an air fryer cannot achieve this pressure level. Most kernels remain hard and do not expand. It is often found that even with long cooking times, popcorn kernels still do not pop. Air fryers cannot make corn kernels burst open and become fluffy popcorn.
What Can Go Wrong with Popcorn
Trying to cook popcorn kernels in an air fryer can cause several problems. Many foods work well in an air fryer, but popcorn kernels do not. The risks include damage to the appliance and messy results. Here are some common issues:
- The air fryer may not reach the right temperature for popping kernels.
- Kernels can overheat and burn, which creates a fire hazard.
- Loose kernels may get stuck on the heating element, risking damage to the device.
- Popped popcorn can fly up and touch the heating element, increasing fire risks.
- Kernels may fall through the basket holes, causing clogs and making a mess.
People should use a stovetop or microwave to cook popcorn kernels. These methods provide the heat and pressure needed for popping. No matter which air fryer brand someone uses, the results will not improve. Air fryers are better for other foods that need crisping or reheating. Popcorn kernels belong in a pot or microwave, not in an air fryer.
Tip: Always choose the right cooking method for each food. Popcorn kernels need high pressure and fast heating, which an air fryer cannot provide.
The five foods you should not put in an air fryer are wet batter foods, leafy greens, large cuts of meat, baked goods, and popcorn kernels. Each one has its own problems. Some cook unevenly, make a mess, or can be unsafe.
