What Is Sweet Potato Toast?

It’s:
- Naturally gluten-free
- Packed with nutrients
- Surprisingly filling
- Customizable for sweet or savory meals
The air fryer is one of the best tools for making sweet potato toast because it cooks the slices evenly without drying them out.

You can make sweet potato toast in a toaster or oven—but the air fryer gives the best balance of texture and speed.

- Crispier edges than oven-baked
