Prepare the seasoning mix: Place the potato wedges in a large bowl. Drizzle with olive oil and sprinkle the garlic powder, smoked paprika, seasoned salt, and cayenne pepper over them. Toss until the potatoes are thoroughly coated with the oil and spices.
Cook the wedges: Arrange the seasoned potato wedges in the air fryer basket. Set the air fryer to 390°F and cook for about 15 to 20 minutes. Shake the basket halfway through cooking to ensure even crisping. Enjoy your extra crispy, spicy potato wedges!
