Sweet potatoes brown naturally, so there is no need to add sugar before air frying. Use them in a rice bowl with edamame or serve beside greens. ### Different sweet potatoes Dense Japanese sweet potatoes may need longer and will have a drier texture than orange-fleshed varieties. ### More than two servings Use batches. A deep pile cooks unevenly, even if the appliance’s advertised capacity sounds large enough. ### Avoid a sticky basket Add sweet sauces after cooking. Sugar in a glaze can burn before the potato center becomes tender. ## Questions before you cook ### Should I soak the cubes? This method does not require soaking. Dry surfaces and enough space in the basket matter more for the intended browned edges. ## Leftovers & food safety Refrigerate leftovers promptly in shallow containers. Do not leave cooked food at room temperature for more than 2 hours, or 1 hour above 90°F / 32°C. Reheat leftovers to 165°F / 74°C. Follow package instructions and use a thermometer where appropriate.
