Absolutely. As I steam sweet potatoes, as a part of my meal prep, I opt this way. For over or air fryer, you don't need to steam the sweet potatoes. Peel and chop them and roast them in an air-fryer or oven. As I have yet to test this recipe in the oven or air-fryer, I cannot give the exact timing and temperature. But you can try at 425 deg F for 20 to 25 mts in the oven and 400 deg F in the air-fryer for 20 mts.
