Preheat the oven to 425 degrees Fahrenheit (220 degrees Celsius). Line a baking sheet with a silicone mat or parchment paper.
In a large bowl, drizzle the sweet potato wedges with the oil, then sprinkle with the potato starch, taco seasoning and salt. Mix until well coated.
Spread the wedges in a single layer on the baking sheet and bake for 20 minutes, until golden and tender.
Notes
Don’t overcrowd the baking sheet, or the wedges will steam instead of crisp. Use two sheets if needed.Cut the wedges evenly so they cook at the same rate.Cornstarch works in place of potato starch at the same amount.
