Preheat your air fryer to 380°F (193°C) for a few minutes to ensure even cooking. Some models do not require preheating, so adjust according to your air fryer's instructions.

Open the can of SpaghettiOs. If you want to add an extra flavor dimension, mix in some grated Parmesan cheese.

Spread the SpaghettiOs in an even layer on the parchment paper in the air fryer basket, or directly in the basket if not using paper. Lightly spray the top with cooking spray or drizzle with a bit of olive oil if desired. This can help achieve a more golden, crispy finish.

Air fry for about 5-8 minutes. Halfway through the cooking time, gently stir or shake the basket to ensure even crisping. Watch closely as cooking times can vary based on the air fryer model and the desired level of crispiness.

Carefully remove the crispy SpaghettiOs from the air fryer. They will be hot, so allow them to cool for a minute or two before serving. Enjoy as is for a crunchy snack, or use as a topping for a creative twist on salads or soups.
