Roasting marshmallows has long been a cherished tradition, evoking the nostalgia of campfires, starry nights, and the sweet, smoky aroma of caramelized sugar. While traditionally done over an open flame, modern kitchen appliances like the air fryer have opened the door to enjoying this delightful treat year-round, regardless of weather or access to a fire pit. Air fryers, with their rapid air circulation and precise temperature control, can replicate the golden-brown exterior and gooey interior of a perfectly roasted marshmallow. This guide will explore how to master the art of air-frying marshmallows, including optimal temperatures, cooking times, troubleshooting, and expert tips for achieving that quintessential roasted perfection.
Temperature is the key to transforming a plain marshmallow into a caramelized delight. For most air fryers, the ideal temperature range is 350°F (175°C) to 375°F (190°C). At this range, the marshmallow’s outer layer begins to brown and crisp without burning too quickly, while the interior melts to a soft, chewy consistency. Cooking at temperatures lower than 350°F may result in a pale, under-roasted marshmallow that lacks the rich flavor of caramelization. Conversely, temperatures above 400°F (205°C) risk scorching the exterior before the marshmallow has a chance to soften inside. Balancing this temperature carefully ensures you achieve that golden-brown perfection every time.

Time is just as critical as temperature. Typically, marshmallows take 3 to 5 minutes to roast in an air fryer set to the recommended range. However, timing may vary depending on the size of the marshmallow and the air fryer model. Smaller, standard-sized marshmallows tend to roast faster, while larger jumbo marshmallows may require closer to 5 minutes. To avoid overcooking, it’s best to check the marshmallows halfway through the cooking process and adjust accordingly. A quick visual inspection can save you from a charred outer layer and a hardened interior.
A perfectly roasted marshmallow should exhibit a golden-brown exterior with subtle caramelized spots, a slight crispness on the outside, and a soft, melty interior. Press gently with a spatula or tongs-if it yields slightly and feels soft yet not runny, it is ready. Avoid relying solely on time; visual and tactile cues are the most reliable indicators. Over-roasted marshmallows turn dark brown to black, harden, and lose that creamy, gooey texture we crave.
Air-fried marshmallows are remarkably simple and require only minimal ingredients:
No oil or additional fats are needed, as marshmallows naturally caramelize under heat.
Adjusting both time and temperature in tandem is crucial for optimal results.
Even with care, mishaps happen:
Yes, you can roast marshmallows in an air fryer. The appliance’s circulating hot air can toast marshmallows quickly, giving them a golden-brown exterior while keeping the inside soft and gooey. However, you need to monitor them closely to prevent burning.
Set your air fryer to a temperature between 350°F and 375°F (175°C-190°C). This range is ideal for browning the marshmallow evenly without causing it to melt too quickly or catch fire.
Roasting marshmallows in an air fryer typically takes 3-5 minutes. The exact time depends on the size of the marshmallow, the air fryer model, and your desired level of browning. It’s best to check them every 1-2 minutes to ensure they don’t burn.
Yes, it’s recommended to place the marshmallows on an air fryer-safe tray or a piece of aluminum foil to prevent them from sticking to the basket. Make sure the tray or foil does not block the air circulation completely, which is essential for even cooking.
Yes, but you should arrange them in a single layer with space between each marshmallow. Overcrowding can cause uneven roasting, with some marshmallows melting faster than others or sticking together.
Roasting marshmallows in an air fryer is generally safe if you follow proper precautions. Avoid leaving them unattended, use a heatproof utensil to remove them, and ensure the marshmallows do not come into direct contact with the heating element, which could cause flames.
Yes, you can make s’mores using air-fried marshmallows. Toast the marshmallows first, then sandwich them between chocolate and graham crackers. Be mindful that marshmallows can be very hot immediately after roasting, so allow them to cool slightly before assembling.
