Ingredients

1 tablespoon extra virgin olive oil
1 ½ cups plain/unseasoned panko breadcrumbs
1 teaspoon Old Bay Seasoning
½ teaspoon sea salt, plus extra for seasoning
¼ teaspoon freshly ground black pepper, plus extra for seasoning
1 tablespoon chopped fresh parsley (or 1 teaspoon dried parsley flakes)
⅓ cup mayonnaise
1 pound skinless cod fillets (3–4 fillets)
4–5 small hamburger or potato buns, split
½ cup Homemade Tartar Sauce, or store-bought

Optional for Serving:

Quick coleslaw
Sliced tomato

Instructions

1. Prepare Ahead

Make the tartar sauce and coleslaw if using, and refrigerate until ready to assemble.

2. Toast the Panko

Preheat the oven to 425°F (220°C) and line a baking sheet with foil; spray generously with nonstick cooking spray.
Heat olive oil in a large skillet over medium heat. Add panko, Old Bay Seasoning, ½ teaspoon salt, and ¼ teaspoon black pepper. Toast, stirring frequently, until light golden brown (3–4 minutes).
Transfer toasted breadcrumbs to a shallow bowl and mix with parsley. Let cool completely.
(Breadcrumbs can be prepared up to 2 days ahead and stored at room temperature in an airtight container.)

3. Prepare the Fish

Cut the fish fillets to fit the buns, slicing in half if needed for ½-inch thickness. Season both sides with salt and pepper.
Brush each piece generously with mayonnaise, then coat completely with the toasted panko, pressing crumbs gently to adhere.

4. Bake the Fish

Place the breaded fish on the prepared baking sheet. Spray tops lightly with nonstick cooking spray.
Bake 12–15 minutes, until golden brown and cooked through.

5. Toast the Buns

Place the split buns cut-side up on a baking sheet and toast in the oven for about 3 minutes.

6. Assemble the Sandwiches

Spread tartar sauce on both the top and bottom halves of each bun.
Layer with lettuce or coleslaw, then top with the baked fish. Add sliced tomato if desired and serve immediately.
