Preheat your air fryer to 400°F (200°C) for 2-3 minutes. This crucial step ensures your tots start cooking immediately when added.
Place frozen tater tots in a bowl and lightly spray with oil or drizzle with 1-2 teaspoons of olive oil. Toss gently to coat. While technically optional, this small amount of oil significantly enhances crispiness.
Season the tater tots with garlic powder, onion powder, paprika, salt, and pepper if desired. Toss to distribute the seasonings evenly.
Arrange the tater tots in a single layer in your air fryer basket. Avoid overcrowding—this is crucial for proper air circulation and even crisping. Work in batches if necessary.
Cook for 5 minutes, then shake the basket or flip the tots with tongs to ensure even cooking.
Continue cooking for another 5-7 minutes until the tots are golden brown and crispy. The exact time may vary depending on your air fryer model and how crispy you prefer your tots.
Check for doneness by selecting one tot and testing its crispiness. If needed, cook for additional 1-2 minute intervals until they reach your desired level of crispiness.
Transfer to a serving dish immediately and serve hot with your favorite dipping sauces.
