In a small bowl, mix Dijon mustard, whole grain mustard, honey, olive oil, lemon juice, garlic powder, smoked paprika, black pepper, sea salt, and red pepper flakes (optional) until smooth.
Pat salmon fillets dry and place them skin-side down. Brush glaze generously over each piece.
Preheat air fryer to 390°F (200°C) for 3 minutes.
Spray or line the air fryer basket. Place salmon inside without overlapping.
Cook for 8–10 minutes until salmon flakes easily or reaches 125–130°F internal temp.
Remove, rest for 2 minutes, and garnish with parsley or chives. Serve warm with sides.
