Start with 1 pound of cooked salmon, flaked into small pieces. Remove any skin or bones for best texture.
In a large mixing bowl, combine chopped green onions, minced garlic, and grated fresh ginger. Add Italian herbs, paprika, dried parsley, salt, and pepper. Stir to blend evenly.
Add slightly beaten eggs, sour cream, lemon juice, hot sauce (if using), and lemon zest to the bowl. Mix until fully combined and creamy.
Gently fold in flaked salmon and 1 1/2 cups Panko bread crumbs. The mixture should be moist but hold together when formed. Add more Panko if too wet.
Divide mixture into 8 equal portions. Shape each into a patty about 3 inches in diameter and 1 inch thick. Place on a plate or tray.
Preheat air fryer to 375°F (190°C) for 3-5 minutes. Lightly spray both sides of each salmon cake with oil spray.
Arrange salmon cakes in a single layer in the air fryer basket without touching. Cook 10-12 minutes, flipping halfway, until crispy and golden brown.
Remove salmon cakes and serve warm. Enjoy alone or with salad, lemon, or dipping sauce.
