Preheat oven to 350 degrees F.
Place the fish fillets on a parchment-lined baking sheet. Pat dry with a paper towel. Brush the olive oil over the top and sides of the fillets.
In a small bowl, mix the sea salt, garlic powder, Italian seasoning, onion powder, and ground black pepper. Sprinkle half the mixture of the fillets. In a medium bowl, mix together the panko breadcrumbs, parmesan cheese, and the remaining spices.
Sprinkle the panko mixture over the pollock fillets and gently press down to make sure the breadcrumbs and cheese are sticking to the fish.
Bake for 18 to 20 minutes or until fish reaches an internal temperature of 145 degrees F on an instant-read thermometer.
If you’d like the panko topping to be crispier, broil the fish on high for 1 minute. Serve immediatley.
