1. Preheat Your Air Fryer: Preheat the air fryer to 400°F (200°C). This step is crucial for optimal cooking results, ensuring the potatoes cook evenly from the start.

2. Prepare the Potatoes: Place the frozen potatoes in the air fryer basket. Make sure they are evenly spaced and not touching each other. You can coat the potatoes with a light layer of oil to enhance crispiness.

3. Cooking Time and Temperature: Set the air fryer temperature to 400°F (200°C) and cook for 20-30 minutes. The exact cooking time depends on the size of the potatoes. Shake or flip the potatoes halfway through to ensure even cooking.

4. Checking Doneness: Use a fork or knife to check if the potatoes are fork-tender inside and crispy outside. If they need more time, adjust the cooking time in 5-minute increments until they reach the desired doneness.

5. Adding Toppings: After cooking, add your favorite toppings like butter, cheese, or sour cream. If you want the toppings to melt, return the potatoes to the air fryer for an additional 2 minutes.
