Prep the air fryer: Preheat your air fryer to 390°F (200°C) for about 3–5 minutes.
Lightly spray the basket with oil to prevent sticking.
Mix the base: In a large bowl, add the drained, flaked salmon. If the salmon contains skin and soft bones, mash them in—they add calcium and disappear into the mixture.
Add the binders and flavor: Stir in the egg, mayonnaise, Dijon, Old Bay, garlic powder, salt, and pepper. Mix until well combined.
Fold in the texture: Add the breadcrumbs, onion, celery, and parsley.
Stir until the mixture holds together when pressed. If it’s too wet, add a tablespoon or two more breadcrumbs. If it’s too dry, add a spoonful of mayo or a splash of lemon juice.
Shape the patties: Divide the mixture into 8 small cakes or 6 medium ones.
Press firmly so they hold their shape, about 1/2 to 3/4 inch thick.
Lightly oil the tops: Spray or brush the tops with a small amount of oil for better browning.
Air fry: Arrange the cakes in a single layer without crowding. Cook for 8–10 minutes, flipping halfway. They’re done when golden and crisp on both sides and heated through.
Finish and serve: Squeeze fresh lemon over the hot cakes.
Serve with your favorite sauce and a simple side like salad, slaw, or roasted veggies.
