Air fryer ovens are fast becoming a staple in Nigerian kitchens. Whether you’re making crispy yam fries, juicy chicken suya, roasted bole with fish, or even healthy versions of chin-chin, this gadget is proving to be more than just a passing trend. For many households, an air fryer oven is helping to reduce oil consumption, cut cooking time, and simplify meal prep—all while still delivering the delicious flavors we love.

But here’s the thing: owning an air fryer is one thing, using it correctly is another.

Many Nigerians are guilty of making small but costly mistakes with their air fryers. These errors may lead to soggy meals, burnt snacks, uneven cooking, or even damaging the appliance over time. If you’ve ever wondered why your plantain doesn’t crisp up properly or why your fried chicken looks perfect outside but raw inside, chances are you’re making one of these common mistakes.

In this guide, we’ll uncover the 10 most common air fryer mistakes Nigerians make—and how to avoid them. Each mistake comes with a practical fix so you can start cooking smarter, healthier, and tastier meals.

1. Overcrowding the Basket or Tray

The Mistake:
You pile up large portions of yam, plantain, or turkey wings in the air fryer, hoping to cook everything at once.

Why It’s Wrong:
Air fryers work by circulating hot air around your food. When the basket is too full, the hot air can’t reach every side of the food. The result? Some parts get burnt while others remain undercooked or soggy.

The Fix:
Cook in batches. For example, instead of loading all your yam fries at once, split them into two or three rounds. You’ll get a much crispier result. If you have a large family, consider investing in a 12L CookEX Air Fryer Oven, which has multiple racks. That way, you can cook larger portions at once without overcrowding.

2. Skipping Preheating

The Mistake:
You switch on your air fryer and immediately toss in your food.

Why It’s Wrong:
Just like traditional ovens, air fryers need to preheat to reach the right temperature. If you start cooking before preheating, your food spends extra time heating up instead of crisping, which can make plantains or chips soggy.

The Fix:
Always preheat your air fryer for 3–5 minutes. Luckily, the CookEX Air Fryer Oven has one-touch digital presets that handle preheating automatically. No guesswork—just press, wait, and cook.

3. Using Too Much Oil

The Mistake:
You drizzle—or worse, pour—oil over your food as if you’re still deep-frying.

Why It’s Wrong:
Air fryers are designed to use minimal oil. Adding too much oil causes food to steam instead of fry, and it can also create smoke inside the fryer.

The Fix:
Stick to a teaspoon of oil or a light spray. For example, a quick spray of oil is all you need for crispy yam chips or roasted sweet potatoes. The whole point of air frying is to enjoy crispiness with up to 80% less oil—and the CookEX Air Fryer Oven makes this easy.

4. Not Shaking or Turning Food Midway

The Mistake:
You put your chicken wings, suya, or chin-chin in the fryer and leave them untouched until the timer goes off.

Why It’s Wrong:
Without flipping or shaking, the parts of your food closer to the heat source may cook faster, while the others remain soft or pale.

The Fix:
Shake the basket or turn food halfway through cooking. The CookEX Air Fryer Oven comes with a rotating mesh basket and even a rotisserie function for whole chicken, so your meals cook evenly without much effort from you.

5. Cooking Wet Batters

The Mistake:
You pour akara batter, pancake mix, or wet dough straight into the fryer tray.

Why It’s Wrong:
Air fryers aren’t built for wet batters. Instead of setting, the batter drips, makes a mess, and won’t crisp up.

The Fix:
Avoid very wet batters. If you want akara, fry lightly in a pan first before finishing in the air fryer. For moi-moi, use silicone molds or ramekins inside the air fryer oven for perfect results.

6. Forgetting to Dry Food Properly

The Mistake:
You place freshly washed fish, chicken, or yam into the fryer without drying.

Why It’s Wrong:
Moisture prevents crisping and encourages steaming. You’ll end up with limp fries or soggy chicken.

The Fix:
Pat food dry with a kitchen towel before seasoning. This simple step is the difference between crunchy yam fries and disappointing soggy ones.

7. Not Cleaning After Every Use

The Mistake:
You leave behind crumbs, grease, or oil from your last meal, thinking it won’t matter.

Why It’s Wrong:
Food residue causes smoke, funky smells, and can even shorten your air fryer’s lifespan.

The Fix:
Clean your fryer after every use. With the CookEX Air Fryer Oven, this isn’t stressful—the non-stick trays and baskets are dishwasher-safe, and the stainless-steel interior wipes clean easily.

8. Ignoring the Right Temperature and Time Settings

The Mistake:
You use the same temperature and time for everything.

Why It’s Wrong:
Different meals require different settings. Suya, moi-moi, roasted corn, and yam fries can’t all cook the same way. Wrong settings can burn the outside while leaving the inside raw.

The Fix:
Follow recipe guides and use your presets. The CookEX has 10 one-touch programs for common dishes like chicken, pizza, and baked goods, making life much easier.

9. Cooking Oversized Meals

The Mistake:
You try to stuff a huge whole chicken or goat leg into your fryer.

Why It’s Wrong:
Large meals block airflow, which results in uneven cooking. The outside may look brown while the inside is undercooked.

The Fix:
Cook meals in sizes your fryer can handle. For bigger meats like a whole chicken, use the rotisserie function in the CookEX Air Fryer Oven. It rotates the chicken so it cooks evenly on all sides, with juicy insides and crispy skin.

10. Expecting Deep-Fried Taste Every Time

The Mistake:
You expect your air fryer to make food taste exactly like deep-fried akara from the roadside or Lagos-style fried chicken.

Why It’s Wrong:
Air fryers use hot air, not deep oil, so the taste will be slightly lighter and less greasy. That’s not a bad thing—it’s actually healthier.

The Fix:
Adjust your expectations. Instead of looking for an identical taste, embrace the healthier, lighter crisp air frying provides. Over time, you may even prefer it to traditional frying.
