Prep the cauliflower: Cut into evenly sized, bite-sized florets.
Make the seasoning: In a small bowl, combine garlic powder, smoked paprika, turmeric, salt, pepper, and parmesan.
Coat: Place florets in a large bowl, toss with the seasoning mix, then drizzle with olive oil. Mix well to coat.
Preheat: Heat the air fryer to 380°F (190°C) for 5 minutes.
Cook: Arrange florets in a single layer in the basket (work in batches if needed).
Air fry: Cook for 10 minutes, shaking halfway through, until golden brown and crisp.
Serve: Enjoy immediately—great with a creamy, spicy mayo dip.
