The time and temp of air fryer sweet potato wedges is 400F for 6-8 minutes per side. The time is a guideline depending on the model and the size of the wedges. Start with 8 minutes on one side, flip, and then 4-8 minutes on the second side. Generally, smaller potato wedges cook up faster than larger cuts. I've found that larger models (like the Ultrean I use) tend to take longer than smaller models like the Ninja Speedi that I also tested this recipe in.
