Why is my food soggy instead of crispy in the air fryer?

The main cause is an overcrowded basket that blocks air circulation. Never fill beyond two-thirds capacity. Other causes include wet food that was not patted dry, no oil at all, and temperature set too low. Always dry your food, add a light oil spray, and preheat the appliance for 3 minutes.

What temperature should I set the air fryer to for each type of food?

General rule: thin vegetables at 200°C for 10 minutes, fries at 190-200°C for 18-22 minutes, chicken at 180-200°C for 15-25 minutes depending on the cut, fish at 180°C for 10-12 minutes, pastries at 160-170°C. Always reduce by 10-20°C compared to traditional oven recipes.

Can you use regular parchment paper in an air fryer?

Yes, but with caution. Prefer perforated liners designed for air fryers. If using regular parchment, punch holes for air circulation. Never place paper without food on top to weigh it down, as it can fly up and touch the heating element, creating a fire hazard. Always keep paper below food.

Can you cook frozen food directly in the air fryer?

Yes, this is one of the best uses for an air fryer. Frozen nuggets, fries, and battered items cook directly without thawing. Add 2 to 3 extra minutes and reduce the temperature by 10°C compared to oven instructions on the package. Shake the basket halfway through for even results.

Why is my air fryer producing smoke?

Smoke usually comes from burnt grease residue on the heating element or from using oil with a low smoke point. Clean the appliance after every use. Use heat-resistant oils like avocado or grapeseed oil. Adding a small amount of water to the bottom of the drawer helps catch dripping grease.

10 Air Fryer Mistakes to Avoid (and How to Fix Them)

Why so many air fryer disappointments?

You bought an air fryer excited about crispy chips with little oil. But your first results are disappointing: soggy chips, dry chicken, uneven cooking. Don't panic. In 90% of cases, the problem isn't the appliance but easily fixable bad habits.

Mistake 1: Overloading the basket

An air fryer works by circulating hot air at high speed around food. An overfilled basket blocks airflow, producing steamed food instead of crispy food.

Golden rule: never fill the basket beyond two-thirds capacity.
For chips: a single layer is ideal. If you must stack, shake every 5 minutes.
For families: cook in two batches rather than piling everything in. Or consider a dual-basket air fryer.

Mistake 2: Skipping preheating

Placing food in a cold air fryer means the first minute heats the appliance rather than cooking the food, resulting in longer cook times and less crispiness.

Preheat for 3-5 minutes at cooking temperature before adding food.
Exception: delicate items like thin fish fillets or pastries can start in a cold unit.

Mistake 3: Wrong temperature

Setting maximum temperature for everything burns the outside before the inside cooks.

Food	Ideal temperature	Approximate time
Fresh chips	180-190°C	18-22 min
Frozen chips	200°C	15-18 min
Whole chicken	180°C	25-35 min
Fish fillets	190°C	8-12 min
Vegetables	190-200°C	10-15 min
Steak	200°C	8-12 min
Cakes/muffins	160°C	15-20 min

General rule: reduce temperature by 10-20°C compared to conventional oven recipes.

Mistake 4: Forgetting to shake or flip

Hot air comes mainly from above. Surfaces touching the basket base receive less direct heat. Without flipping, you get a golden top and a pale bottom.

Chips and small pieces: shake every 5-7 minutes.
Meat and fish: flip at the halfway point with silicone tongs.

Mistake 5: Putting in wet food

Wet food creates steam instead of crisping. Excess moisture prevents the Maillard reaction responsible for browning and crunch.

Pat dry with paper towels before cooking.
Marinades: drain excess. Meat should be damp, not dripping.
Breaded items: rest for 10 minutes in the fridge before cooking for better adhesion.

Mistake 6: Using zero oil

The air fryer needs very little oil but not zero. Without any oil, fresh foods (not pre-fried) will be dry and lack crispiness. Frozen pre-fried items need no additional oil.

Fresh food: 1-2 teaspoons of oil, applied by spray.
Oil the food, not the basket. Oil on an empty basket burns and smokes.

Mistake 7: Using the wrong oil

Extra virgin olive oil has a smoke point of 160-190°C. At 200°C it produces smoke and bitter flavours. Commercial cooking sprays contain lecithin that damages non-stick coatings.

Recommended: avocado oil (271°C), grapeseed oil (216°C), groundnut oil (232°C), refined olive oil (210°C).
Best investment: a refillable glass spray bottle (8-12 euros).

Mistake 8: Neglecting cleaning

Accumulated grease residue burns during subsequent uses, creating smoke, bad odours, and unpleasant flavours. Long-term build-up reduces efficiency and can present a fire risk.

After each use: wash the basket with hot soapy water or in the dishwasher.
Weekly: clean the heating element with a soft brush.

See our complete maintenance guide for a detailed protocol.

Mistake 9: Not adapting oven recipes

Temperature: reduce by 10-20°C compared to conventional oven.
Time: reduce by 20-25%.
Example: roast chicken at 200°C for 60 min in oven = 180°C for 45 min in air fryer.

Mistake 10: Poor ventilation

The air fryer expels hot air from the rear. Placed too close to a wall or under a shelf, it cannot ventilate properly.

Minimum clearance: 10-15 cm behind and above the unit.
Under the extractor hood if possible to evacuate steam and cooking odours.

Summary table

Mistake	Impact	Quick fix

4. No flipping	Uneven browning	Shake every 5-7 min
5. Wet food	No crispiness	Pat dry first
6. Zero oil	Dry, no crunch	1-2 tsp spray oil
7. Wrong oil	Smoke, bitter taste	High smoke-point oil
8. No cleaning	Smoke, odours, risk	Clean after each use
9. Unadapted recipes	Over/undercooking	-20°C, -25% time
10. Poor ventilation	Reduced performance	10-15 cm clearance

Troubleshooting Guide: What to Do When It Doesn't Work

Observed Problem	Most Likely Cause	Immediate Solution
Soggy fries	Overcrowded basket or no preheating	Reduce to 2/3 basket, preheat 3 min at 200°C, shake halfway
Raw chicken inside	Too thick or temperature too low	Check at halfway, cut thick pieces, use a thermometer
Smoke during cooking	Grease residue or wrong oil	Clean the basket bottom, add 2 tbsp water under basket for fatty foods
Uneven cooking	Food not flipped or basket poorly loaded	Flip halfway, use a rack to elevate
Plastic smell	New appliance or manufacturing residue	Run empty at 200°C for 15 minutes before first use
Coating flaking	Metal utensils or abrasive cleaning	Use silicone/wood only, replace basket

Optimal Settings for the Most Common Foods

Food	Temperature	Time	Key Tip
