Prepare the Marinade: In a mixing bowl, whisk together the maple syrup, soy sauce, minced garlic, and ginger until well combined.
Marinate the Salmon: Place the salmon fillets in a shallow dish or a resealable plastic bag. Pour the marinade over the salmon, ensuring it is evenly coated. Let it marinate for at least 10 minutes (or up to 30 minutes for deeper flavor).
Preheat the Air Fryer: Preheat your air fryer to 375°F (190°C) for about 5 minutes.
Arrange the Salmon: Lightly grease the air fryer basket with cooking spray or line it with baking paper. Place the marinated salmon fillets in the basket, skin-side down, ensuring they are not overcrowded.
Air Fry the Salmon: Cook the salmon for 10-12 minutes, or until it flakes easily with a fork and reaches an internal temperature of 145°F (63°C). Depending on the thickness of your fillets, you may need to adjust the cooking time.
Serve: Carefully remove the salmon from the air fryer and serve immediately, garnished with fresh parsley and lemon wedges if desired.
