In a mixing bowl, whisk together the olive oil, minced garlic, red pepper flakes (if using), salt, and pepper until well combined.
Add the shrimp to the bowl and toss until they are fully coated in the garlic oil mixture.
Preheat your air fryer to 400°F (200°C) for about 5 minutes.
Place the marinated shrimp in a single layer in the air fryer basket. Ensure they are not overcrowded for even cooking.
Cook the shrimp in the air fryer for 6-8 minutes, shaking the basket halfway through, until the shrimp are pink and opaque.
Once cooked, remove the shrimp from the air fryer and immediately sprinkle the grated Parmesan cheese over the shrimp while they are still hot, allowing it to melt slightly.
Garnish with fresh parsley and serve with lemon wedges on the side for an extra burst of flavor.
Notes
Serve the shrimp on a platter with lemon wedges arranged around it, and sprinkle additional parsley for a pop of color.
