Air Fryer Toasted Marshmallow Sweet Potato Rounds

These Air Fryer Toasted Marshmallow Sweet Potato Rounds are a fun and delicious twist on sweet potato casserole and they are super easy to make in the air fryer. Thick slices of sweet potato are air fried until tender with lightly crispy edges, then smashed and topped with a buttery cinnamon brown sugar mixture, crunchy pecans, and mini marshmallows. A quick trip back to the air fryer gets the marshmallows beautifully toasted and golden.

Why You’ll Love These Sweet Potato Rounds

If you love a classic sweet potato casserole with marshmallows and pecans, you are going to love this quick and easy version. Instead of making a casserole, the sweet potatoes are cut into individual rounds, making them perfect for serving as an individual side dish.

The air fryer does a great job of getting the outside of the sweet potatoes lightly caramelized while keeping the center tender and soft. The buttery brown sugar mixture melts into the sweet potatoes, while the pecans add a little crunch and the marshmallows become wonderfully toasted.

And best of all, they don’t take up valuable oven space and they are great for small-batch cooking.

How To Make Air Fryer Toasted Marshmallow Sweet Potato Rounds

(More detailed instructions in recipe card below.)

1. Prepare the sweet potatoes. Wash and scrub the sweet potatoes. You can peel them if that is your preference, but I like to leave the skin on. Slice them into approximately 1/2-inch rounds, place the rounds in a bowl and drizzle with olive oil. Toss to coat evenly and season with salt.
   
2. Air fry. Preheat air fryer to 370 degrees F. Arrange sweet potatoes in a single layer. You may need to cook in batches. Air fry for 10 minutes. Flip and air fry another 8 to 10 minutes or until tender.
   
3. Make the topping. While the sweet potatoes cook, melt the butter and stir in the brown sugar, cinnamon, and pecans.
   
4. Smash the sweet potatoes. Gently press down on each sweet potato round with a fork to make room for the streusel. Don’t flatten them completely. You just want to create a little more surface area and give the topping somewhere to settle.
   
5. Add the toppings. Drizzle the butter mixture over the sweet potatoes. Sprinkle with chopped pecans and top each round with mini marshmallows.
   
6. Toast the marshmallows. Air fry at 400 degrees for 1 to 3 minutes until the marshmallows are poofed and toasted.

Tips For Success

• Try to keep the sweet potato slices as uniform as possible so they cook at the same rate.
• Don’t smash the sweet potatoes too much, you want the sweet potatos to hold their shape.
• Watch the marshmallows carefully, they only need a minute or two to cook.
• Cook in batches if necessary. Crowding the air fryer basket can prevent the sweet potatoes from browning properly.
