Preheat the air fryer: Set to 400°F (200°C) for 2–3 minutes while you season the shrimp.
Pat shrimp dry: Use paper towels to remove excess moisture. Dry shrimp crisp up better and season more evenly.
Season: In a bowl, toss shrimp with olive oil, garlic powder, paprika, onion powder, salt, pepper, red pepper flakes, and lemon zest.
Coat thoroughly.
Arrange in basket: Place shrimp in a single layer in the air fryer basket. A little overlap is fine, but avoid a crowded pile.
Air fry: Cook for 5–6 minutes, shaking the basket halfway through. Shrimp are done when they’re pink, opaque, and slightly curled.
Finish: Squeeze fresh lemon over the top and sprinkle with herbs.
Taste and add a pinch more salt if needed.
Serve: Enjoy right away with rice, salad, tortillas, or your favorite dipping sauce.
