Preheat oven to 425℉.
In a small bowl, combine panko topping ingredients making sure the olive oil evenly coats the panko.
Line a sheet pan with parchment paper or foil. Lay the fish skin side down, tucking under the thinner edges. Season the fish with salt and pepper.
Spread mayonnaise evenly over the fish.
Evenly top with the panko topping, pressing lightly into the mayonnaise.
Place on the middle rack of the oven and bake for 18-22 minutes, depending on the thickness of the filet. Check for doneness in the middle at 18 minutes (the fish should start to flake easily) and put back in the oven in 2 minute increments if necessary until desired doneness.
