Ingredients You’ll Need
Here’s what you’ll need to make these crispy fish sandwiches:
1 tablespoon extra virgin olive oil
1 ½ cups panko breadcrumbs, plain/unseasoned
1 teaspoon Old Bay Seasoning
½ teaspoon sea salt, plus more for seasoning
¼ teaspoon freshly ground black pepper, plus more for seasoning
1 tablespoon chopped fresh parsley (or 1 teaspoon dried parsley flakes)
⅓ cup mayonnaise
1 pound skinless cod fillets (3 to 4 fillets)
4 to 5 small hamburger or potato buns, split
½ cup homemade or store-bought tartar sauce
Optional toppings: Quick coleslaw, sliced tomato
Step-by-Step Directions
Preheat the oven to 425°F (220°C). Line a baking sheet with parchment paper.
Prepare the coating: In a shallow bowl, mix together the panko breadcrumbs, Old Bay seasoning, sea salt, black pepper, and parsley.
Season the cod: Pat the fillets dry with paper towels. Brush lightly with olive oil to help the coating stick.
Coat the fillets: Press each piece of fish into the breadcrumb mixture until fully coated on all sides.
Bake: Arrange the coated fillets on the prepared baking sheet. Bake for 12–15 minutes, or until golden brown and cooked through. The fish should flake easily with a fork.
Toast the buns (optional): While the fish bakes, toast your hamburger or potato buns for extra texture.
Assemble the sandwich: Spread mayonnaise on the bottom bun, add the baked fish fillet, and top with tartar sauce.
Add extras: Pile on optional toppings like crunchy coleslaw or juicy tomato slices. Cap with the top bun and serve immediately.

Measuring cups and spoons

Tips for Success
Dry the fish well: Patting the cod fillets dry ensures the breadcrumbs stick better.
Don’t overcrowd the pan: Leave space between fillets so they crisp evenly.
Check doneness: Cod cooks quickly. At 12–15 minutes, it should be opaque and flake with a fork.
Toast the buns: This small step adds crunch and prevents sogginess.
Homemade tartar sauce: If you have a few minutes, make tartar sauce from scratch with mayonnaise, pickles, lemon juice, and fresh herbs—it elevates the sandwich beautifully.
Recipe Variations
Switch the fish: Swap cod for haddock, tilapia, halibut, or even salmon for a different twist.
Go spicy: Add cayenne pepper or paprika to the breadcrumb mix for extra heat.
Gluten-free option: Use gluten-free panko breadcrumbs and buns.
Lighter version: Swap mayonnaise for Greek yogurt in the sandwich base.
Make it deluxe: Add cheese (like sharp cheddar or American) and melt it on top of the fish before assembling.
Serving Suggestions
Pair your crispy oven-baked fish sandwich with:
Sides: French fries, sweet potato wedges, or a fresh green salad.
Drinks: A crisp white wine (like Sauvignon Blanc), a cold beer, or sparkling water with lemon.
Condiments: Extra tartar sauce, hot sauce, or even a squeeze of fresh lemon juice.
How to Store Leftovers
Refrigerator: Store leftover fish fillets in an airtight container for up to 2 days.
Reheat: For best results, reheat in the oven or air fryer to maintain crispiness. Avoid microwaving, as it makes the coating soggy.
Freezer: You can freeze baked fish fillets (without buns or toppings) in a freezer-safe bag for up to 1 month. Reheat directly from frozen in the oven.
Frequently Asked Questions (FAQ)

Yes! Cook at 400°F (200°C) for 10–12 minutes, flipping halfway through, until golden and crispy.
2. What type of fish works best for sandwiches?
Cod is a great choice because it’s mild and flaky, but haddock, tilapia, or halibut work well too.

Yes, you can bake the fillets ahead, store them in the fridge, and reheat them in the oven. Assemble the sandwiches just before serving.
4. How can I make the coating extra crispy?
Toast the panko breadcrumbs lightly in a skillet before coating the fish. This adds an extra crunch factor.
5. What if I don’t have Old Bay seasoning?
You can substitute with a mix of paprika, celery salt, garlic powder, and black pepper.
