Prep Shrimp: If you're using frozen shrimp, make sure they are fully thawed. Pat the shrimp dry with a paper towel to remove excess moisture.
Prepare Garlic Butter: In a bowl, combine the minced garlic, melted butter, lemon juice, parsley, salt, pepper, and red pepper flakes (if using). Stir until well combined.
Coat Shrimp: Add the shrimp to the bowl and toss until they are thoroughly coated in the garlic butter mixture. Allow the shrimp to marinate for 10-15 minutes to let the flavors seep in.
Preheat Air Fryer: Preheat your air fryer to 400°F (200°C) for about 5 minutes.
Arrange Shrimp: Spray the air fryer basket with olive oil to prevent sticking. Arrange the shrimp in a single layer in the basket, making sure they do not overlap.
Cook Shrimp: Air fry the shrimp at 400 degrees F (200°C) for 5-7 minutes or until the shrimp are pink and cooked through. You do not need to flip the shrimp halfway, but you can if you want to ensure even browning.
Serve: Carefully remove the shrimp from the air fryer (they'll be hot!). Serve immediately, garnished with extra parsley and lemon wedges if desired. Enjoy as a standalone dish or with a side of rice, pasta, or a fresh salad.
