Air fryers have taken the culinary world by storm, offering a healthier alternative to traditional deep-frying while delivering delicious and crispy results.

However, many home cooks have noticed an unpleasant smell from their air fryers during use.

It’s natural to be concerned about this mysterious odor and how it might affect your food or health.

Key Takeaways

  • Unpleasant smells in an air fryer can be caused by residue from previous cooking, low-quality oil, overcrowding the basket, cooking with strong-smelling ingredients, and overcooking or burning food.
  • To prevent these odors, it is essential to regularly clean the air fryer after every use and use high-quality oils that have a smoke point of at least 400°F. It is also advisable to preheat the air fryer before cooking and use recommended temperature settings and timings.
  • Vinegar or lemon juice can neutralize any unpleasant aromas from strong-smelling ingredients. Additionally, keeping the fryer in a well-ventilated area while cooking can help reduce unwanted smells in your kitchen.
  • Avoid using abrasive cleaners or steel wool when cleaning your air fryer as they may damage its non-stick surface. Furthermore, plastic baskets are generally safe for air frying but should be replaced if emitting an overwhelming plastic smell during initial usage.

What Causes Odors In An Air Fryer?

Food particles, grease build-up, low-quality oil, overcrowding the fryer basket, cooking with strong-smelling ingredients, and burning or overcooking food can all contribute to unpleasant odors in an air fryer.

Residual Food Particles And Grease Buildup

As a home cook, you’re no stranger to the occasional mess left behind after preparing a delicious meal. One of the main reasons your air fryer might smell is due to residual food particles and grease buildup that accumulates over time.

When you cook with an air fryer, tiny bits of food can stick to the basket or tray, especially when frying greasy items like bacon or chicken wings.

To avoid dealing with this unappetizing odor in your kitchen, make it a habit to clean your air fryer basket and tray promptly after each use.

For example, if you recently made some tasty sweet potato fries but notice a lingering aroma in your air fryer afterward, don’t wait for days before tackling the cleanup.

Instead, once it’s cooled down enough to handle safely (following manufacturer guidelines), thoroughly clean it using hot soapy water and a soft-bristle brush or sponge designed explicitly for nonstick surfaces.

Use Of Low-quality Oil

If you notice an unpleasant smell from your air fryer, the culprit could be the oil. Using low-quality oil can lead to a rotten odor that lingers long after cooking. To avoid this issue, opt for high-quality oils with a smoke point of at least 400°F.

Examples include avocado oil, peanut oil, or sunflower oil.

In addition to its impact on smell, using low-quality oil can also affect the taste and texture of your food. It may result in oily and greasy dishes that are unappetizing.

Overcrowding The Fryer Basket

When using an air fryer, it’s important to avoid overcrowding the fryer basket. Putting too much food in the basket can cause various problems, including uneven cooking and unpleasant smells.

When the basket is packed too tightly, hot air circulation is restricted, resulting in some parts of the food being overcooked while others are undercooked.

Overcrowding can also result in smoke and strong odors coming from your air fryer which could be a safety hazard.

The best approach is to cook smaller batches or use multiple baskets if available instead of trying to cram as much as possible into one batch.

Cooking With Strong Smelling Ingredients

I love cooking with strong-smelling ingredients like garlic and onion in my air fryer, but it can leave an unwanted odor. The smell can stick around even after cleaning the basket and tray.

To combat this, I recommend using vinegar or lemon juice to neutralize the odor.

Another tip is to cook these ingredients separately before adding them to your dish in the air fryer. This way, you can avoid overcooking them and creating a more robust, lingering smell.

It’s also essential to keep your kitchen well-ventilated while cooking with strong-smelling ingredients in order to prevent the scent from spreading throughout your home.

Overcooking Or Burning Food

If you’ve ever burned food in your air fryer, you know how unpleasant the resulting smell can be.

Overcooking or burning food can quickly turn a sweet-smelling kitchen into one that’s filled with acrid smoke and an overpowering odor.

To prevent this from happening, follow recommended cooking times and temperatures for the foods you’re cooking. Avoid overcrowding the basket since it can cause uneven cooking and burning.

Keep an eye on your food while it’s cooking to ensure that it reaches the correct level of doneness without going too far.

Tips For Eliminating Air Fryer Smells

To eliminate unpleasant smells from your air fryer, clean the fryer basket and tray after every use, use high-quality oil, avoid overcrowding the basket, and neutralize odors by using vinegar or lemon.

Clean The Fryer Basket And Tray After Use

Keeping your air fryer clean is critical to preventing odors from building up.

Here are some tips for cleaning the fryer basket and tray after use:

After every use, wash the basket and tray with soap and water to remove residual food particles or grease buildup.

– Use a soft sponge or cloth to avoid scratching the non-stick coating.

– Soak the basket and tray in warm soapy water before scrubbing if there are stubborn stains.

– Dry the basket and tray with a clean towel or let them air dry before storing them.

– Avoid using abrasive cleaners or steel wool, which can damage the non-stick coating or leave scratches.

By taking these simple steps, you can ensure that your air fryer remains odor-free and in good condition for years to come.

Avoid Overcrowding The Fryer Basket

Overcrowding the fryer basket is a common mistake when using an air fryer that can lead to unpleasant odors.

When too much food is crammed into the basket, it can prevent hot air from circulating evenly and cooking all the food properly.

This can result in some pieces of food being overcooked or burnt while others remain undercooked and soggy.

To prevent this problem, always follow the manufacturer’s recommended guidelines for capacity and spacing between items in the basket.

Generally, it’s best to leave at least half an inch of space around each piece of food to allow for proper circulation of hot air.

If you have a lot of food to cook, consider doing multiple batches instead of trying to cram everything into one round.

Use Vinegar Or Lemon To Neutralize Odors

I’ve found that vinegar and lemon are great natural solutions for neutralizing any odors that may linger in your air fryer.

Here’s how to use them:

1. Fill a bowl with equal amounts of water and white vinegar.

2. Place the bowl inside the air fryer basket and turn on the appliance.

3. Let the vinegar solution heat up for 10 minutes, then turn off the air fryer and remove the bowl.

4. Wipe down the inside of the basket and any other parts with a clean cloth or sponge.

5. Rinse with water and dry thoroughly.

Alternatively, you can cut a lemon in half and rub it over the inside of the basket before wiping it down with a clean cloth or sponge.

The acidity in lemon can help break down any residual smells, leaving your air fryer smelling fresh and clean.

If you’re experiencing strong odors from cooking with certain ingredients, add herbs like rosemary or thyme to your recipe to help mask any lingering smells.

Remember always to keep your air fryer well-maintained by cleaning it regularly after each use to avoid any unwanted odors building up over time.

How To Prevent Foul Odors From Occurring In An Air Fryer

Prevent foul odors in your air fryer by preheating it before use, using the recommended temperature and cooking time, avoiding extremely greasy foods, and keeping the fryer in a well-ventilated area.

Preheat The Fryer And Use A Timer

I always preheat my air fryer for a few minutes before cooking because it helps to cook the food evenly.

Here are some tips on how to do it:

1. Set the temperature and preheat your air fryer for 3-5 minutes before cooking.

2. Use a timer to ensure you cook your food in the recommended time.

3. Don’t overcrowd the basket; this can cause uneven cooking and create unwanted odors.

4. Follow the manufacturer’s preheating time and temperature instructions for best results.

5. Remember to keep your air fryer in a well-ventilated area to avoid kitchen smells and fumes building up.

6. Using a timer ensures that you don’t overcook or burn your food, which can cause unpleasant odors and damage to your air fryer.

By following these simple steps, you can help eliminate any unwanted odors from your air fryer while ensuring that your food cooks evenly and thoroughly every time.

Keep The Fryer In A Well-ventilated Area

As air fryers cook food, steam and odors are released into the air. This can lead to a buildup of unwanted smells in your kitchen. To combat this problem, it is important to keep your air fryer in a well-ventilated area when in use.

One option is to turn on the vent hood or open a nearby window while using the air fryer. You could also move the appliance closer to an exhaust fan if possible.

In addition, following proper maintenance protocols such as cleaning regularly and avoiding overcrowding can also reduce unwanted smells emanating from your air fryer during use.


The FAQs section addresses common concerns, including whether air fryers can cause health problems, if using an air fryer with a plastic basket is dangerous, and how often the appliance should be cleaned.

Is It Dangerous To Use An Air Fryer With A Plastic Basket?

Many air fryers come with a plastic basket that can emit a strong plastic smell when initially used.

While this may be concerning, using an air fryer with a plastic basket is generally not dangerous as long as you follow the manufacturer’s instructions and safety guidelines.

However, if the plastic smell persists or becomes overwhelming, it may be best to contact the manufacturer or consider getting a replacement basket.

Additionally, it is essential to properly clean and maintain your air fryer to prevent any potential safety hazards from buildup or damage.

How Often Should I Clean My Air Fryer?

As a home cook who frequently uses an air fryer, it is essential to clean the appliance regularly. Ideally, it would be best if you aimed to clean your air fryer after every use.

In addition to cleaning after each use, you may need to occasionally give your air fryer a deeper clean.

This involves removing the appliance’s removable parts and washing them with soap and water.

Regardless of how often you choose to do it, regular cleaning can help prolong the lifespan of your air fryers and keep it functioning safely and efficiently over time.

Is the Plastic Taste in Air Fryer Food Caused by the Foul Odor Emitting from the Appliance?

Is the plastic taste in air fryer food caused by the foul odor emitting from the appliance? While some may be concerned that the air fryer food tastes like plastic due to the smell it gives off during cooking, there can be other factors at play. It’s important to consider the quality of the air fryer, the cleaning routine, and the type of food being cooked, as these can all contribute to any lingering plastic taste.


In conclusion, unpleasant odors in your air fryer can be caused by various factors such as overcooking, overcrowding the basket, and cooking with strong-smelling ingredients.

To eliminate these smells, you should clean your air fryer by regularly washing the basket and tray after use and using high-quality oil.

Additionally, it is essential to follow manufacturer instructions for proper usage and maintenance to prevent foul odors from occurring in the first place.
