Begin by washing the red potatoes thoroughly to remove any dirt. Pat them dry.
Cut the potatoes into bite-sized cubes (about 1-inch pieces) to ensure even cooking.
In a mixing bowl, combine the cut potatoes with olive oil, garlic powder, paprika, salt, and black pepper. Toss until the potatoes are well-coated with the oil and seasonings.
Preheat your air fryer to 400°F (200°C) for about 5 minutes.
Once preheated, place the seasoned potatoes into the air fryer basket in a single layer. Avoid overcrowding for best results.
Cook the potatoes at 400°F (200°C) for 25 minutes. Shake or stir the basket halfway through the cooking time to ensure even crispiness.
Once done, check for doneness by piercing a piece with a fork; they should be tender on the inside and crispy on the outside.
Remove the potatoes from the air fryer and let them cool for a couple of minutes. Optionally, garnish with fresh parsley before serving.
