Air fryer temperatures in Celsius confuse many cooks, so converting your chicken thigh timing correctly makes all the difference. If you keep asking how long to cook chicken thighs in air fryer celsius, the short answer is 22 to 28 minutes at 180°C for bone-in thighs and 16 to 20 minutes at 190°C for boneless ones.
That range moves depending on thickness, whether the bone is still in, and how hot your machine actually runs. Most air fryers sold in Europe, Australia, and Canada use Celsius, so you never need to touch a Fahrenheit chart again.
Below you get exact times, temps, and a simple method that works every single time.
Why Celsius Settings Matter For Chicken Thighs
Chicken thighs are forgiving, but they still need to hit a safe internal temperature of 74°C. Celsius air fryers run cooler than most people assume, so guessing often leads to pink meat near the bone.
Thighs also carry more fat and connective tissue than breasts. That fat needs enough heat and time to render, otherwise the skin stays rubbery and the meat feels tough.
The good news is that thighs are hard to overcook compared to white meat. A few extra minutes won’t ruin them the way it would a chicken breast.
How Long To Cook Chicken Thighs In Air Fryer Celsius
Use this table as your starting point. Times are based on a preheated air fryer and thighs at fridge temperature, not frozen.
- Boneless, skinless thighs at 190°C: 16 to 20 minutes
- Boneless thighs with skin at 190°C: 18 to 22 minutes
- Bone-in thighs at 180°C: 22 to 28 minutes
- Bone-in thighs with skin at 180°C: 25 to 30 minutes
- Frozen bone-in thighs at 180°C: 30 to 35 minutes
Always flip the thighs halfway through. This helps both sides brown evenly and stops the skin from sticking to the basket.
Boneless Chicken Thighs At 190°C
Boneless thighs are thin and cook fast. Set your air fryer to 190°C and give them 16 minutes, then check.
If the internal temp reads 74°C, you are done. If not, add 2 to 3 minutes and check again.
Bone-In Chicken Thighs At 180°C
Bone-in thighs need a lower temp for a longer time. The bone slows heat from reaching the center, so 180°C for 22 to 28 minutes is the sweet spot.
Test right next to the bone, not in the thickest part of the meat. That is where undercooked spots hide.
Skin-On Thighs For Crispy Results
Skin needs dry heat and space. Pat the thighs completely dry with paper towels before seasoning.
Arrange them skin side up in a single layer. Never stack them, or the skin steams instead of crisping.
Step-By-Step Cooking Method
- Preheat your air fryer to 180°C or 190°C for 3 to 5 minutes.
- Pat the thighs dry and trim any loose fat or hanging skin.
- Rub with oil and season with salt, pepper, paprika, and garlic powder.
- Place thighs in a single layer, skin side up, without touching.
- Cook for half the total time, then flip with tongs.
- Finish cooking until the internal temp reaches 74°C.
- Rest the thighs for 5 minutes before serving.
Resting matters more than most people think. It lets the juices settle so they don’t run out on the plate.
How To Check Doneness Without A Thermometer
A meat thermometer is the only truly reliable way, but you can use these backups if you don’t own one.
- Pierce the thickest part near the bone. The juices should run clear, not pink.
- Cut into the meat at the bone. There should be no red or pink flesh.
- The meat should pull away from the bone with light pressure.
If you see any pink near the bone, put the thighs back in for 3 minutes at 180°C and check again.
Common Mistakes That Ruin Air Fryer Thighs
Overcrowding The Basket
Air needs to move around each piece. If the thighs touch, they cook unevenly and the skin stays soft.
Cook in batches if you have to. It takes longer but the results are far better.
Using The Wrong Temperature
Many people crank the air fryer to 200°C thinking faster is better. That burns the outside while the inside stays raw.
Stick to 180°C for bone-in and 190°C for boneless. Those two numbers cover almost every case.
Skipping The Preheat
A cold basket means the first few minutes are wasted. Preheat for at least 3 minutes so the thighs start browning right away.
Not Drying The Skin
Moisture is the enemy of crisp skin. Dry the thighs well and you will notice the difference immediately.
Adjusting Times For Your Specific Air Fryer
Every air fryer runs a little different. A cheap 4-litre model may run cooler than a premium 6-litre one, even at the same setting.
Do a test batch first. Cook two thighs and note how long they take to reach 74°C. Then adjust your standard timing by that difference.
- Small air fryers under 4 litres: add 2 to 3 minutes
- Large air fryers over 6 litres: subtract 1 to 2 minutes
- Oven-style air fryers: times usually match the table closely
Altitude also plays a small role. At high elevations, add a couple of minutes to be safe.
Marinades And Seasonings That Work Well
Thighs take on flavor easily, so you have plenty of options. Just avoid sugar-heavy marinades at high heat, since they burn fast.
- Olive oil, lemon, oregano, and garlic
- Smoked paprika, cumin, and chili powder
- Soy sauce, honey, and ginger, brushed on at the end
- Plain salt and pepper for a simple, crispy result
If your marinade contains honey or sugar, brush it on during the last 5 minutes only.
Storing And Reheating Leftovers
Let leftover thighs cool, then store them in a sealed container in the fridge for up to 4 days.
To reheat, set the air fryer to 160°C and warm them for 5 to 7 minutes. This keeps the skin from getting soggy.
Never reheat in the microwave if you want crispy skin. It turns rubbery within seconds.
Quick Recap Of The Key Numbers
- Boneless thighs: 190°C for 16 to 20 minutes
- Bone-in thighs: 180°C for 22 to 28 minutes
- Frozen thighs: 180°C for 30 to 35 minutes
- Safe internal temp: 74°C
- Always flip halfway and rest for 5 minutes
Once you memorize these Celsius settings, cooking chicken thighs becomes second nature. No more guessing, no more dry meat, and no more pink centers near the bone.
