In a mixing bowl, combine honey, soy sauce, minced garlic, olive oil, rice vinegar (if using), black pepper, and salt. Whisk together until well combined.
Place the salmon fillets in the bowl, ensuring they are evenly coated with the honey garlic mixture. Let it marinate for about 10 minutes.
Preheat your air fryer to 400°F (200°C) for 5 minutes.
Once preheated, place the marinated salmon fillets in the air fryer basket, skin side down. Make sure they are arranged in a single layer.
Air fry the salmon for 8-10 minutes, or until the salmon is cooked through and flakes easily with a fork. The internal temperature should reach 145°F (63°C).
Carefully remove the salmon from the air fryer and transfer to a serving plate. Drizzle any leftover glaze from the bowl over the salmon.
Garnish with chopped green onions before serving.
