Roasting pumpkin seeds in an air fryer transforms a humble byproduct of pumpkin carving into a crunchy, flavorful snack that’s both nutritious and versatile. Unlike oven roasting, which can take significant time and requires constant monitoring, the air fryer uses rapid hot air circulation to cook seeds evenly, producing a perfectly toasted texture in a fraction of the time. Not only does this method retain the natural nutty flavor of the seeds, but it also allows for precise control over seasoning and texture. Whether you prefer them lightly salted, savory with garlic and herbs, or sweetly spiced with cinnamon and sugar, air-fried pumpkin seeds are an irresistible treat that balances taste with convenience.
Temperature is crucial in achieving the ideal crunch and flavor profile for your pumpkin seeds. Most recipes and expert guides recommend 325°F (163°C) to 350°F (177°C) as the optimal range. Temperatures below this range may result in seeds that are dry and chewy rather than crisp, while higher temperatures can cause seeds to burn quickly due to their small size and low moisture content.
Setting the temperature at 325°F allows for slower, more controlled roasting, bringing out the natural oils in the seeds and enhancing their nutty aroma. Pushing the temperature to 350°F creates a faster roast with slightly more pronounced browning, but it requires close monitoring to avoid overcooking. Essentially, the goal is to heat the seeds enough to evaporate residual moisture while encouraging the Maillard reaction-the chemical process that produces that characteristic golden-brown, roasted flavor.

The ideal roasting time in an air fryer typically ranges from 10 to 15 minutes, depending on seed size and moisture content. Smaller seeds roast more quickly, while larger, thicker seeds may require the full 15 minutes to achieve uniform crispness.
It’s essential to stir or shake the basket every 4-5 minutes to ensure even roasting. Air fryers circulate hot air rapidly, which can cause uneven cooking if the seeds are left undisturbed. For first-time roasting, it’s best to start checking at the 10-minute mark and adjust based on appearance and aroma. Seeds are done when they turn lightly golden, emit a toasted nutty scent, and achieve a satisfying crunch when cooled.
Unlike oven baking, the air fryer’s compact space makes visual cues and aroma more reliable than strict timing. Look for these indicators:
Remember, seeds continue to crisp slightly after removal due to residual heat, so avoid overcooking in the air fryer.
The beauty of air-fried pumpkin seeds is their simplicity. Here’s a basic list:
Optional flavor enhancers:
Adjusting the temperature outside the 325-350°F range will affect texture and flavor:
Cooking time is equally critical:
Adjustments in temperature and time should always consider seed size, moisture content, and your preferred crunch level.
Even with careful monitoring, roasting pumpkin seeds can go awry:
Yes, it is recommended to wash pumpkin seeds to remove any remaining pulp or stringy bits. After washing, pat them dry thoroughly with a paper towel. Dry seeds roast more evenly and achieve a crispier texture in an air fryer.
It is best to season pumpkin seeds before air frying. Toss the seeds with a small amount of oil and your preferred seasonings, such as salt, paprika, garlic powder, or cinnamon. This ensures the flavors adhere to the seeds and roast evenly.
A temperature of 325°F to 350°F (160°C to 175°C) is ideal for roasting pumpkin seeds in an air fryer. This range allows the seeds to cook evenly without burning while achieving a golden, crispy texture.
Roasting pumpkin seeds in an air fryer typically takes 10 to 15 minutes. Shake or stir the seeds halfway through cooking to ensure even roasting. Cooking times may vary slightly depending on the air fryer model and the size of the seeds.
While pumpkin seeds can be roasted without oil, adding a small amount of oil helps them crisp up and allows seasonings to stick better. One teaspoon of oil per cup of seeds is usually sufficient.
Pumpkin seeds are done when they are golden brown and have a firm, crisp texture. Taste-testing a few seeds is the best way to confirm doneness, as they continue to crisp slightly after cooling.
Yes, fully cooled pumpkin seeds can be stored in an airtight container at room temperature for up to two weeks. For longer storage, refrigerate or freeze them to maintain freshness and crunchiness.
