Keep the skins on your potatoes, but make sure to wash or scrub any excess dirt from them. Cut each potato in half lengthwise. Cut each half in 3 to 4 wedges, depending how big your potato is.
6 medium Russet Potatoes
Place the potato wedges in a large bowl of cool water, making sure that they are fully submerged. Let them soak in the water for 1 hour, in order to help remove excess starch for a crispier result.
Remove the soaked wedges from the bowl and place on a clean dish towel. Dry them off as much as possible. Any excess moisture will work against you to achieve a crispy potato.
Preheat the oven to 400F.
Transfer the dried-off wedges to a large clean bowl. Sprinkle the cornstarch over the wedges and stir with a rubber spatula until well covers. Drizzle the oil over the potatoes. Sprinkle on the onion powder, garlic powder, salt, and smoked paprika. Stir until well coated.
1½ tablespoon Corn Starch, ¼ cup Cooking Oil, 1 teaspoon Smoked Paprika, 1 teaspoon Garlic Powder, 1 teaspoon Onion Powder, 1 teaspoon Salt
Line a large baking sheet pan with parchment paper. Place the coated potato wedges on the prepared tray, spacing them out evenly. Bake the wedges for an initial 20 minutes.
Remove the wedges from the oven and flip them all over. Return to the oven for another 15-20 minutes, depending on how crisp you prefer them. Take out of the oven and let them rest for 4-5 minutes before serving.
