Quick Answers
Can you roast peanuts in an air fryer?
Yes. Air fryers are one of the easiest ways to roast peanuts. The circulating hot air cooks them evenly, creating a crisp texture and deep roasted flavor without requiring much oil.
How long do peanuts take in an air fryer?
Most raw peanuts roast in 10 to 12 minutes at 180°C (356°F). Cooking time varies slightly depending on whether the peanuts are shelled, blanched, or skin-on.
What is the best temperature for roasting peanuts?
The ideal roasting temperature is 180°C (356°F) for most varieties. Lower temperatures work well for delicate nuts, while higher temperatures can cause uneven roasting or burning.
Do I need to preheat my air fryer?
Preheating is optional but recommended. A preheated basket helps the peanuts begin roasting immediately, resulting in more even cooking.
Can I roast peanuts without oil?
Absolutely. Peanuts naturally contain healthy oils that develop during roasting. Adding oil is optional and mainly used when applying seasonings.
Are air-fried peanuts healthier?
Yes. Air-fried peanuts require little or no added oil while maintaining their protein, healthy fats, fiber, vitamins, and minerals. They make an excellent high-protein snack when eaten in moderation.
Can I roast shelled peanuts?
Yes. Shelled peanuts roast slightly faster than peanuts with skins. Keep an eye on them during the last few minutes of cooking to avoid over-roasting.
Can I roast peanuts with the skin on?
Yes. Many people prefer roasting peanuts with their skins because the skins add flavor and antioxidants. Once cooled, the skins can easily be rubbed off if desired.
Can I roast raw peanuts without soaking?
Yes. There is no need to soak raw peanuts before air frying. Simply spread them in the basket and roast until golden and fragrant.
Which air fryer setting should I use?
Use the Air Fry or Roast function at 180°C (356°F). Shake the basket every 3 to 4 minutes to ensure even roasting.
Why Use an Air Fryer to Roast Peanuts?
Traditional oven roasting works well, but an air fryer offers several advantages.
- Faster cooking time
- More even heat circulation
- Crisp texture
- No need to heat the entire oven
- Minimal or no oil required
- Easy cleanup
- Perfect for small batches
- Energy efficient
Because air fryers circulate hot air rapidly around the peanuts, they roast more evenly than many conventional ovens.
Ingredients
You’ll only need a few simple ingredients.
- 2 cups raw peanuts
- ½ teaspoon salt (optional)
- 1 teaspoon neutral oil (optional)
- Optional seasonings of your choice
Recommended oils include:
- Peanut oil
- Avocado oil
- Sunflower oil
- Olive oil
Oil is only necessary if you want seasonings to stick more effectively.
Equipment
- Air fryer
- Mixing bowl
- Wooden spoon
- Measuring spoons
- Airtight storage container
How to Roast Peanuts in an Air Fryer
Step 1: Preheat the Air Fryer
Preheat your air fryer to 180°C (356°F) for about 3 minutes.
Although not absolutely required, preheating helps produce more consistent roasting.
Step 2: Prepare the Peanuts
Inspect the peanuts and remove any damaged pieces.
If using oil or seasoning, toss the peanuts until evenly coated.
Step 3: Arrange in the Basket
Spread the peanuts into a single even layer.
Avoid overcrowding.
The hot air must circulate freely around every peanut for even roasting.
Step 4: Air Fry
Cook at 180°C (356°F).
Shake the basket every 3 to 4 minutes.
Typical cooking time:
10–12 minutes.
Step 5: Check for Doneness
Perfectly roasted peanuts should be:
- Light golden brown
- Fragrant
- Crisp after cooling
- Slightly darker inside when split
Remember that peanuts continue cooking for several minutes after being removed from the air fryer.
Step 6: Cool Completely
Transfer the peanuts to a plate immediately.
Allow them to cool for 15 to 20 minutes.
Cooling is essential because peanuts become much crispier as they cool.
Air Fryer Peanut Cooking Time Chart
| Peanut Type | Temperature | Time |
|---|---|---|
| Raw peanuts | 180°C | 10–12 min |
| Shelled peanuts | 180°C | 8–10 min |
| Skin-on peanuts | 180°C | 10–12 min |
| Blanched peanuts | 170°C | 8–9 min |
| Salted peanuts | 170°C | 7–8 min |
| Frozen peanuts | 180°C | 12–14 min |
Cooking times may vary slightly depending on the air fryer model and the quantity being cooked.
How Do You Know When Peanuts Are Done?
Many people accidentally overcook peanuts because they judge them while they are still hot.
Instead, look for these signs:
- Pleasant roasted aroma
- Slightly darker center
- Dry surface
- Even golden color
- Crunchy texture after cooling
If the peanuts still feel soft after cooling, return them to the air fryer for another 1 to 2 minutes.
Should You Add Oil?
For plain roasted peanuts, oil is unnecessary.
However, adding a teaspoon of oil helps:
- Salt stick better
- Spices coat evenly
- Create a richer roasted flavor
- Improve browning slightly
Because peanuts naturally contain healthy oils, they roast beautifully even without additional fat.

- Potassium
- Antioxidants
When roasted without excessive oil or sugar, peanuts make a satisfying snack that can help keep you feeling full for longer.
Are Air-Fried Peanuts Healthy?
Air-fried peanuts are considered a healthier alternative to deep-fried snacks because they require little or no added oil while retaining most of their natural nutrients.
They are suitable for many balanced diets and are a good source of protein and healthy fats. Portion control is still important, as peanuts are calorie-dense despite their nutritional value.
Expert Tips for Perfect Roasted Peanuts
- Roast in small batches for even cooking.
- Shake the basket every few minutes.
- Do not overcrowd the basket.
- Let the peanuts cool completely before judging their texture.
- Store only after they have cooled fully.

Common Mistakes When Roasting Peanuts in an Air Fryer
Roasting peanuts is simple, but a few small mistakes can make the difference between perfectly crunchy peanuts and a burnt or chewy batch. Understanding these common issues will help you get consistent results every time.
1. Overcrowding the Basket
One of the biggest mistakes is filling the air fryer basket too full.
Air fryers work by circulating hot air around the food. When peanuts are piled on top of each other, the hot air cannot reach every peanut evenly.
Best Practice
- Spread peanuts in a single layer.
- Cook in batches if preparing a large quantity.
- Leave enough space for proper airflow.
2. Cooking at Too High a Temperature
Many people assume hotter is better.
Unfortunately, peanuts brown very quickly because they naturally contain oils.
Temperatures above 190°C (375°F) often cause the outside to burn before the inside is properly roasted.
Best Temperature
180°C (356°F)
This provides even roasting while preserving flavor.
3. Forgetting to Shake the Basket
Unlike baking in an oven, peanuts should not sit in one position throughout cooking.
Shaking the basket redistributes the peanuts and prevents hot spots.
Recommended Schedule
- 3 minutes
- 6 minutes
- 9 minutes
This simple step dramatically improves even roasting.
4. Judging the Texture While Hot
Freshly roasted peanuts always feel softer than expected.
Many people continue cooking them because they don’t seem crunchy.
In reality, peanuts crisp up during cooling.
Always allow them to cool completely before deciding whether they need additional cooking.
5. Leaving Peanuts Inside the Hot Basket
Even after switching off the air fryer, the basket remains very hot.
Residual heat continues roasting the peanuts.
Immediately transfer them to a plate or baking tray to stop the cooking process.
Why Are My Peanuts Burning?
Burnt peanuts usually result from one or more of these factors:
- Temperature too high
- Cooking too long
- Basket overcrowded
- Air fryer not shaken
- Small peanut varieties roasting faster
- Different air fryer model producing higher actual temperatures
Solution
Reduce the cooking temperature by 10°C or shorten the cooking time by one to two minutes.
Why Are My Peanuts Still Soft?
Soft peanuts are surprisingly common.
Possible reasons include:
- They haven’t cooled yet.
- Cooking time was too short.
- Air fryer basket was overcrowded.
- Peanuts absorbed moisture from humid storage.
Solution
Allow the peanuts to cool for 20 minutes.
If they remain soft, air fry for another 2 minutes and cool again.
Why Are My Peanuts Roasting Unevenly?
Uneven roasting usually happens because hot air cannot circulate evenly.
Causes
- Basket too full
- No shaking
- Mixed peanut sizes
- Air fryer fan blocked by overcrowding
Solution
Cook smaller batches and shake regularly.
Why Do Roasted Peanuts Become Chewy?
Chewy peanuts usually indicate moisture.
Common causes include:
- Stored before cooling
- Humid kitchen
- Airtight container while still warm
Always cool peanuts completely before storing them.
Can You Roast Different Types of Peanuts?
Yes, but each type behaves slightly differently.
Raw Peanuts
The most popular choice.
Excellent flavor after roasting.
Cooking Time
10–12 minutes
Blanched Peanuts
These roast slightly faster because the skins have been removed.
Cooking Time
8–9 minutes
Skin-On Peanuts
Provide a richer, slightly earthy flavor.
The skins also contain beneficial antioxidants.
Cooking Time
10–12 minutes
Shelled Peanuts
Because they have less outer protection, shelled peanuts roast faster.
Cooking Time
8–10 minutes
Salted Peanuts
Already roasted salted peanuts only need reheating if desired.
Raw salted peanuts should be monitored closely because the salt can encourage faster browning.
Air Fryer Settings by Brand
Every air fryer cooks a little differently, but the general principles remain the same.

Expert Tips from Experience
- Buy fresh, high-quality raw peanuts for the best flavor.
- Roast small batches instead of overloading the basket.
- Stir or shake consistently for even browning.
- Cool peanuts on a wide plate rather than leaving them in the basket.
- Taste one peanut during the final minutes instead of relying only on the timer.
- Record the perfect cooking time for your specific air fryer model, as wattage and airflow vary between brands.
Method
Step 1: Preheat
Preheat your air fryer to 180°C for 3 minutes.
Step 2: Prep the Peanuts
If using oil, lightly toss peanuts with oil and salt (and spices if you want flavored peanuts).
Skip oil if you prefer completely dry roasting.
Step 3: Air Fry
Spread peanuts in a single layer in the basket.
Air fry at 180°C for 8–10 minutes.
Step 4: Shake & Roast Evenly
Shake the basket once or twice in between (around 4–5 minutes mark).
Step 5: Cool Down
Let them cool for 5–10 minutes.
They will become crispier as they cool.
Pro Tips (This is where most people mess up)
- Don’t overcrowd the basket, or they’ll roast unevenly
- Slightly undercook rather than overcook — peanuts burn fast at the end
- If using skin-on peanuts, rub them after cooling to remove skin easily
- For extra crunch, extend 1–2 minutes but keep checking
