Panko Crusted Cod

Ingredients

• 4 (about 454–567 g / 16–20 oz total)thick cod fillets
• to tastesalt and pepper
• 85 g (6 tablespoons) or 60 ml (4 tablespoons)salted butter or extra-virgin olive oil
• 2garlic cloves, grated or minced
• 1 teaspoonlemon zest
• 60 g (1 cup)unseasoned panko
• 15 g (4 tablespoons) chopped fresh, or 2 tablespoons driedparsley
• to tastesalt and pepper
• 30 ml (2 tablespoons)mayonnaise
• 10 ml (2 teaspoons)Dijon mustard

Instructions

1. 1

   Heat the oven

   Preheat the oven to 220°C (425°F), without convection or fan assistance. Spray a baking sheet with cooking spray or brush it lightly with cooking oil.

2. 2

   Warm the oil

   If using olive oil instead of butter for the topping, warm it slightly if you like; this can help it take on the garlic and lemon flavour.

3. 3

   Mix the topping

   Melt the butter in a medium microwave-safe bowl, or melt it in a saucepan and transfer it to a bowl. Stir in the garlic and lemon zest, then leave for 1 minute. Add the panko, parsley, and a little salt and pepper; mix well and set aside.

4. 4

   Season the cod

   Pat the cod fillets dry with kitchen paper and season with salt and pepper. Arrange them on the prepared baking sheet.

5. 5

   Add the mustard

   Mix the mayonnaise and Dijon mustard in a small bowl. Divide the mixture over the cod and spread it into an even layer with the back of a spoon.

6. 6

   Top with panko

   Divide the panko mixture over the fillets. Spread it evenly and press it gently into the mayonnaise layer so it stays in place.

7. 7

   Check for doneness

   Cooking time depends on the thickness of the fish, so check it after about 10 minutes. If the fish is cooked but the topping needs more colour, briefly use the oven grill; if the topping is browned before the fish is done, loosely cover the fish with foil for the remaining cooking time. The fish is done at 63°C (145°F) internally and should flake easily when tested with a fork.

8. 8

   Bake the fish

   Bake in the preheated oven for 10–15 minutes, until the cod is cooked through and the panko topping is golden brown.

What is panko-crusted cod?

This is a baked cod dish with a crisp coating of panko, the light, flaky breadcrumbs associated with Japanese cooking. The preparation here has an American-style weeknight-dinner feel: mild fish, a buttery topping and a simple oven method.

Garlic and lemon zest season the crumbs, while a thin layer of mayonnaise and Dijon mustard helps them adhere. That combination gives the fillets a savoury, tangy base beneath the crunchy top.

Nutrition and macros by portion

The nutrition label shows one serving as written: 379 calories, 28g protein, 12g carbs, 24g fat.

The panko supplies most of the carbohydrates, while butter or olive oil and mayonnaise contribute much of the fat. Cod provides the protein. Pair a fillet with plenty of vegetables and a modest serving of potatoes or another starchy side for a balanced plate.

The panko topping

Butter or olive oil: warm fat carries the garlic and lemon flavour through the crumbs. If using olive oil, gently warming it first is optional.

Panko and parsley: stir the crumbs and herbs through the seasoned fat until evenly coated. Unseasoned panko lets you control the seasoning yourself.

Dry the fish first

Dry fillets: patting the cod with kitchen paper removes surface moisture, which helps the mayonnaise mixture spread evenly. Season the fish before adding the topping.

Even coverage: spread the mustard mixture over the top of each fillet, then press on the crumbs lightly. Pressing too firmly can compact the coating rather than leaving it loose and crisp.

Watch the cooking cues

Thickness matters: the 10–15 minute baking time is a guide, as thicker pieces need longer than thinner ones. Start checking at about 10 minutes.

Two signs of doneness: the cod should reach 63°C (145°F) internally and separate into flakes when tested with a fork. The panko should be golden; use the oven grill briefly if the fish is done but the crumbs need colour.

Keep the topping in balance

The mayonnaise and Dijon form a thin layer rather than a thick sauce. Dividing them evenly across the fillets gives the crumbs a surface to stick to without overwhelming the fish.

If the topping is already deeply browned while the cod still needs time, loosely cover the fillets with foil. This shields the crumbs from further browning as the fish finishes cooking.

What to serve with it

Serve the cod with vegetables such as green beans, broccoli or a crisp salad to bring freshness alongside the buttery topping. Steamed or roasted potatoes also make a simple, hearty accompaniment.

A lemon wedge at the table suits the garlic and zest in the coating. Keep the sides simply seasoned so the crunchy panko remains the main feature.

Recipe notes & tips

• Use fillets of similar thickness so they are more likely to finish cooking at the same time.
• Keep the panko unseasoned so you can adjust the salt and pepper to taste.
• Pat the cod dry before seasoning to help the topping sit neatly on the fish.
• Warm the olive oil slightly if using it in place of butter to help it take on the garlic and lemon flavour.
• Begin checking the fish at about 10 minutes, especially if the fillets are thin.
• Use the oven grill briefly only after checking that the fish is cooked, and watch the topping closely.

Variations

• Use olive oil: replace the butter with extra-virgin olive oil for the panko mixture.
• Choose dried parsley: use 2 tablespoons dried parsley in place of the fresh parsley.
• Add more lemon: serve with lemon wedges for extra citrus at the table.
• Adjust the mustard: use a little less Dijon for a milder topping.
• Season the crumbs: add a little extra salt and pepper to the panko mixture to suit your taste.

Common mistakes to avoid

• Wet cod: the topping may not sit as well; pat the fillets dry before seasoning.
• Uneven coating: some bites may lack crunch; divide and spread the panko across the fillets evenly.
• Compacted crumbs: the topping can lose its light texture; press it gently rather than firmly.
• Relying only on the timer: fillet thickness changes cooking time; check from about 10 minutes and use the doneness cues.
• Over-browned topping: cover the fish loosely with foil if it browns before the cod is cooked through.
• Pale topping: if the cod is cooked but the panko needs colour, use the oven grill briefly and keep watch.

How to store

Refrigerate leftovers in a covered container and eat within 2 days. Reheat in an oven until hot throughout; the panko may soften during storage and will not be as crisp as when freshly baked.
