01 - In a medium mixing bowl, combine olive oil, garlic powder, smoked paprika, salt, black pepper, and oregano. Mix until evenly blended.
02 - Add the cubed salmon to the bowl. Toss gently to ensure each piece is thoroughly coated with the marinade.
03 - Preheat the air fryer to 400°F for 2 minutes.
04 - Place the marinated salmon cubes in a single layer inside the air fryer basket, cooking in batches if necessary to avoid overcrowding.
05 - Cook the salmon at 400°F for 7 to 8 minutes, shaking the basket halfway through, until cooked through and lightly crisped on the edges.
06 - Transfer the cooked salmon onto a serving plate. Drizzle with fresh lemon juice and sprinkle with chopped parsley if desired. Serve immediately.
