Dice the salmon into bite-sized pieces, about 1-inch cubes, and pat them dry with a paper towel.
In a small bowl, combine the panko breadcrumbs, grated Parmesan, lemon zest, garlic powder, and a pinch of salt and pepper. Mix well until evenly distributed.
Drizzle olive oil over the salmon pieces and gently toss to coat them evenly, helping the coating stick better.
One by one, press each salmon piece into the breadcrumb mixture, turning to coat all sides thoroughly. Place the coated pieces on a plate or tray.
Preheat your air fryer to 400°F (200°C) for about 3 minutes, ensuring even crisping.
Arrange the coated salmon bites in a single layer in the air fryer basket, leaving space between each piece for air circulation.
Cook the salmon bites for 8–10 minutes, shaking or flipping halfway through, until they are golden brown and crispy on the outside, and the fish is tender inside.
Once cooked, transfer the bites to a plate and let them rest for a minute to settle and enhance the crunch.
Squeeze fresh lemon juice over the bites or serve with lemon wedges for an extra burst of citrus freshness.
Enjoy your crispy, flavorful salmon bites while warm, with a nice contrast between the crunchy coating and tender fish inside.
