Pat the salmon fillets dry with paper towels to remove excess moisture, which helps achieve crispiness.
Sprinkle chili powder and salt evenly over both sides of each fillet, pressing gently to adhere the spices and enhance flavor.
Preheat your air fryer to 400°F (200°C) for about 3-5 minutes, ensuring even cooking and crispy results.
Lightly spray the air fryer basket with olive oil spray to prevent sticking and promote crispness.
Lay the seasoned fillets skin-side down in the preheated air fryer basket, making sure they aren’t touching for even airflow.
Cook the salmon for 8-10 minutes, checking around the 8-minute mark for a golden, crackly crust and opaque flesh.
Once cooked, carefully remove the fillets from the air fryer and transfer to a serving plate.
Squeeze fresh lemon juice over the crispy salmon, then sprinkle with chopped herbs for a bright, fresh finish.
Serve immediately with your favorite sides, enjoying the crackling crust and tender, flavorful flesh.
