Marshmallows are often associated with campfires, cozy gatherings, and the sweet, gooey pleasure of toasted perfection. Traditionally roasted over open flames, marshmallows develop a crisp, caramelized exterior that gives way to a soft, melted interior-a combination that has delighted people for generations. But what if you don’t have access to a campfire? Or you want to satisfy that craving in the comfort of your kitchen, without smoke or mess? Enter the air fryer.
An air fryer, often celebrated for its ability to replicate frying and roasting with minimal oil, uses high-velocity hot air to cook food evenly and quickly. This makes it an unexpectedly ideal tool for achieving that golden-brown, perfectly toasted marshmallow. However, the process is slightly delicate: marshmallows can melt, burn, or stick to surfaces if not handled correctly. This guide delves deeply into the science, timing, and techniques to help you achieve the ultimate air-fried marshmallow.
Temperature control is critical when toasting marshmallows. Unlike cookies or meats that can tolerate higher temperatures, marshmallows are primarily sugar and gelatin, which react quickly to heat. Too low a temperature, and your marshmallow will remain pale and soft, missing the signature caramelized surface. Too high, and it can burn or collapse into a sticky puddle.
For most air fryers, the optimal temperature range is 320°F to 350°F (160°C to 175°C). This range allows the outer layer to caramelize evenly without instantly liquefying the interior. Some high-powered air fryers may require adjusting the temperature downward slightly, as hot air circulation in these models is more intense.
The key is gentle, even heat: the goal is to allow the sugar in the marshmallow to undergo the Maillard reaction, forming that golden-brown crust while preserving the pillowy inside.

Timing is as delicate as temperature. Unlike roasting over a fire where you can continuously rotate the marshmallow, air fryers cook using circulating hot air, which means one side may brown faster than expected. Typically, marshmallows take 3 to 5 minutes to toast.
It’s crucial to check frequently because the difference between perfectly golden and burnt can be mere seconds. Unlike baking, you don’t want to “set it and forget it”.
Knowing when your marshmallow is perfectly toasted is partly visual and partly tactile:
To toast marshmallows in an air fryer, you’ll need:
No oil or butter is needed, as marshmallows contain enough sugar to caramelize naturally.
Even in the best air fryer, mistakes happen. Here’s how to handle them:
Yes, marshmallows can be toasted in an air fryer. The appliance provides consistent heat that can brown the marshmallows evenly. Using a metal or heat-safe tray helps prevent sticking and allows for better airflow.
The ideal temperature is typically 350°F (175°C). This allows the marshmallows to toast evenly without burning the exterior too quickly while giving a soft, gooey interior.
Marshmallows generally take 3-5 minutes to toast, depending on their size and the desired level of browning. It’s recommended to check them after 2 minutes to avoid burning, as air fryers can vary in intensity.
Yes, lining the air fryer basket with aluminum foil or parchment paper is recommended. This prevents marshmallows from sticking to the basket and makes cleanup easier. Ensure there are holes or gaps to allow proper airflow.
Yes, but avoid overcrowding the basket. Leave space between each marshmallow so hot air circulates evenly, ensuring uniform toasting. Toasting too many at once can result in uneven browning or sticking together.
To prevent sticking, lightly grease the tray or use parchment paper. Additionally, avoid placing marshmallows too close together and monitor the cooking time closely, as marshmallows can quickly melt if left too long.
Yes, flavored or jumbo marshmallows can be toasted. However, larger marshmallows may require slightly longer cooking times, and flavored varieties may brown faster due to added sugars. Always check periodically to avoid burning.
