Start by cleaning and deveining the shrimp if not already done. Pat them dry using paper towels to remove excess moisture. This helps the seasoning stick better and ensures a crispier texture.
In a mixing bowl, combine olive oil, minced garlic, parmesan cheese, and spices. Toss the shrimp well until evenly coated with the mixture. Make sure each piece is fully covered for maximum flavor.
Preheat your air fryer to 400°F (200°C) for about 3–5 minutes. This step ensures even cooking and helps achieve a slightly crispy outer layer. Skipping preheating may result in uneven texture.
Place shrimp in a single layer in the air fryer basket without overcrowding. Cook for 8–10 minutes, flipping halfway through for even cooking. Shrimp should turn pink and slightly golden when done.
Remove the shrimp carefully and transfer to a serving dish. Sprinkle fresh parsley on top and add a squeeze of lemon juice if desired. Serve immediately for the best taste and texture.
