Wash and scrub 3 cups of diced potatoes thoroughly. Peel if desired and cut into ½-inch cubes. Pat dry.

In a mixing bowl, combine diced potatoes with 1.5 tablespoons of olive oil and seasoning: 1 teaspoon of salt, ½ teaspoon of black pepper, ½ teaspoon of paprika, and optional ¼ teaspoon of garlic powder. Toss until evenly coated.

Preheat the air fryer to 400°F (200°C) for 5 minutes. Lightly spray the basket with oil.

Place the seasoned potatoes into the basket in a single layer. Cook in batches if necessary.

Cook at 400°F (200°C) for 10 minutes, shaking the basket halfway through.

If not crispy, continue cooking for an additional 5-10 minutes until golden brown and fork-tender.

Transfer to a serving bowl, serve hot, and garnish with herbs or extra seasoning if desired.
