10 Air Fryer Mistakes Everyone Makes (And How to Fix Them)
Air fryers are amazing — but even experienced cooks make these mistakes. Avoid these 10 common air fryer mistakes and you’ll get perfect results every single time.
1. Overcrowding the Basket
This is the #1 mistake. When you pack too much food into the basket, air can’t circulate properly. The result? Soggy, unevenly cooked food instead of crispy perfection. Solution: Cook in single layers and do multiple batches if needed. It’s worth the extra time.
2. Not Preheating
Skipping the preheat is like putting food in a cold oven. Your food won’t start cooking immediately, leading to uneven results. Solution: Preheat for 3–5 minutes before adding food. Most modern air fryers have a preheat button.
3. Using Too Much Oil (or None at All)
Air fryers need very little oil — but they do need some for most foods. Too much oil makes food greasy and can cause smoke. Too little makes food dry. Solution: Use 1 teaspoon to 1 tablespoon of oil, or a light spray of cooking oil.
4. Not Shaking or Flipping Food
Air fryers circulate hot air from the top. If you don’t shake or flip your food halfway through, the bottom won’t get crispy. Solution: Shake the basket (or flip larger items) at the halfway point.
5. Using Aerosol Cooking Sprays
PAM and other aerosol sprays contain additives that break down the non-stick coating over time. This permanently damages your air fryer basket. Solution: Use a refillable oil mister instead. Get one on Amazon here.
6. Not Drying Food Before Cooking
Moisture is the enemy of crispiness. Wet food produces steam, which makes food soggy instead of crispy. Solution: Always pat food dry with paper towels before seasoning and cooking.
7. Cooking Foods With Wet Batters
Traditional wet batters (like beer batter for fish) don’t work in an air fryer — they drip through the basket and make a mess. Solution: Use dry breadcrumb coatings instead. Panko breadcrumbs work especially well.
8. Setting the Wrong Temperature
Air fryers cook hotter and faster than regular ovens. If you follow oven temperatures exactly, your food will often burn. Solution: Reduce temperature by 25°F (15°C) compared to oven recipes, and check food 5 minutes earlier than the recipe suggests.
9. Not Cleaning It Regularly
Grease and food residue build up fast. A dirty air fryer smokes, smells bad, and can be a fire hazard. Solution: Clean the basket after every use. Most baskets are dishwasher safe — check your manual.
10. Blocking the Air Vents
Placing your air fryer against a wall or under a cabinet blocks the exhaust vents. This causes overheating and poor performance. Solution: Keep at least 5 inches of clearance on all sides of your air fryer.
Bonus Tip: Using the Wrong Accessories
Not all cookware is safe for air fryers. Metal, silicone, and oven-safe glass are fine. Plastic and non-oven-safe materials will melt. Invest in proper air fryer accessories for the best results.
Frequently Asked Questions
Why is my air fryer food not crispy?
The most common causes are: overcrowding the basket, not preheating, too much moisture on the food, or not enough oil. Fix these four things and your food will be crispy every time.
Can you use parchment paper in an air fryer?
Yes! Parchment paper designed for air fryers (perforated to allow airflow) is great for messy foods. Never use regular parchment paper without holes — it blocks airflow and can be a fire hazard.
Why does my air fryer smoke?
Smoking is caused by excess grease in the bottom of the drawer, or food residue from previous cooking sessions. Clean your air fryer regularly and add a small amount of water to the drawer when cooking fatty foods.
