Slice potatoes into wedges and place on a clean dish towel. Pat dry using the dish towel then transfer to a parchment-lined baking sheet.
Add oil, everyday seasoning and cornstarch and mix using your hands to evenly coat all of the potato wedges. You will need two baking sheets. Spread the potato wedges among the two baking sheets, keeping them in an even layer and spaced apart.
Roast for 30-35 minutes. You can flip the wedges using tongs after about 20 minutes to get them more evenly golden.
