Bring a large pot of salted water to a rolling boil. Add the pasta and cook according to package directions until al dente (firm to the bite). You want it cooked enough to be soft but still hold its shape.

Drain the pasta thoroughly in a colander. Shake well to remove as much water as possible. It's crucial for crispiness that the pasta is dry.

Transfer the drained pasta to a large mixing bowl. Add the olive oil, garlic powder, onion powder, Italian seasoning, salt, and black pepper. Toss well to ensure every piece of pasta is evenly coated.

Stir in the grated Parmesan cheese (or nutritional yeast). Toss again until the cheese is well distributed and clinging to the pasta.

Preheat your air fryer to 375°F (190°C) for 3-5 minutes. (Some air fryers don't require preheating, refer to your model's manual.)

Arrange the seasoned pasta in a single layer in the air fryer basket. Do not overcrowd; work in batches if necessary. Overcrowding will steam the pasta instead of making it crispy.

Air fry for 10-15 minutes, shaking the basket every 5 minutes, until the pasta is golden brown, crispy, and crunchy. The exact time will vary depending on your air fryer and pasta shape.

Remove the crispy pasta chips from the air fryer and transfer them to a serving dish. If desired, garnish with fresh chopped parsley.

Serve immediately with a side of warm marinara sauce or your favorite dip.
