Step 1

Place a rimmed baking sheet in the oven and preheat the oven to 425 degrees F.

Step 2

Pulse the panko and pecans in a food processor until finely chopped. Stir together the panko mixture, rosemary and 1/2 teaspoon of the seafood seasoning in a shallow dish or plate. Whisk the eggs in a separate shallow dish until lightly beaten.

Step 3

Sprinkle the flounder with the remaining 1 1/2 teaspoons seafood seasoning. Dip the fish in the eggs and dredge in the panko mixture until coated.

Step 4

Remove the baking sheet from the oven and coat with the cooking spray. Place the fish on the hot pan and coat the tops with cooking spray. Bake until the fish flakes with a fork, 8 to 10 minutes.

Step 5

Remove the fish from the oven and sprinkle with lemon juice before serving. Garnish with lemon wedges and rosemary sprigs if using.
