Ingredients You’ll Need
- 4 cod fillets (about 150g each), fresh or frozen and thawed
- 60g panko breadcrumbs
- 50g finely grated parmesan cheese
- 3 tablespoons unsalted butter, melted
- 2 tablespoons mayonnaise
- 1 tablespoon Dijon mustard
- 1 teaspoon garlic powder
- 1 teaspoon lemon zest
- 1 tablespoon fresh lemon juice
- 1 teaspoon paprika
- Salt and freshly ground black pepper, to taste
- Fresh parsley, chopped (for garnish)
- Lemon wedges, for serving
Tip: For the best value, buy frozen cod fillets in bulk bags. Thaw them overnight in the fridge, then pat them very dry with kitchen paper before using — this step is crucial for a crisp crust.
How to Make Baked Cod with Parmesan Crust
- Preheat your oven to 200°C (fan-assisted) or 220°C conventional. Line a 9×13 inch baking dish with aluminium foil and lightly grease it. The oven should be fully hot before the fish goes in — you want that initial blast of heat to set the crust.
- Pat the cod fillets dry with kitchen paper until they feel tacky rather than wet. Season both sides generously with salt and pepper. The fish should look matte and feel firm to the touch, with no visible glistening moisture.
- Mix the wet ingredients in a small bowl: combine the melted butter, mayonnaise, Dijon mustard, lemon juice, and garlic powder. Stir until the mixture is smooth, pale yellow, and smells tangy and rich. It should have a thick, spoonable consistency.
- Prepare the crust mixture in a separate shallow dish: stir together the panko breadcrumbs, grated parmesan, lemon zest, and paprika. The mixture should look golden and smell nutty and cheesy. Pinch some between your fingers — it should feel dry and crumbly, not clumpy.
- Coat the fillets by brushing each one generously with the butter-mayonnaise mixture on all sides. Then press the coated fillet firmly into the breadcrumb mixture, turning to coat evenly. You should see a thick, even layer of crumbs adhering to the fish — the surface will look textured and speckled with green flecks of zest.
- Arrange the coated fillets in the prepared baking dish, leaving at least 2cm of space between each one. If they’re touching, the crust will steam rather than crisp. The fillets should sit flat and look like little golden pillows in the dish.
- Bake for 18-20 minutes, or until the crust is deep golden brown and the fish flakes easily when tested with a fork. At the 15-minute mark, check the colour — the crust should be turning a rich amber. The kitchen will smell of toasted parmesan and warm butter. If the top is browning too quickly, tent loosely with foil for the final minutes.
- Rest for 3 minutes after removing from the oven. The fish will continue cooking slightly, and the crust will set and become even crunchier. Garnish with fresh parsley and serve immediately with lemon wedges.
Tips From My Kitchen
- Pat the fish extraordinarily dry: Moisture is the enemy of a crisp crust. After patting the fillets dry, let them sit on a paper-towel-lined plate for five minutes, then pat them again. Any water on the surface will steam and make the crust soggy before it has a chance to brown.
- Use freshly grated parmesan, not the pre-shredded stuff: Pre-grated parmesan contains anti-caking agents that prevent it from melting properly and adhering to the crust. Grate a block yourself — the texture will be powdery and fine, which helps it blend seamlessly with the breadcrumbs.
- Don’t skip the mayonnaise in the coating: I stumbled upon this combination by accident, and it’s been a hit ever since. Mayonnaise might seem unusual, but it’s mostly oil and egg, which means it bakes into a golden, crispy crust while keeping the fish incredibly moist. The butter adds flavour, but the mayonnaise is the texture secret.
- Space the fillets out generously: Overcrowding traps steam, which softens the crust and can make the fish cook unevenly. If you’re batch-cooking for meal prep, use two baking dishes or bake in batches. The extra five minutes is worth it for perfectly crisp results.
- Double the crust mixture for meal prep: When I’m batch-cooking, I make double the breadcrumb mixture and store half in the fridge. Then I can prep a second batch of fish in minutes later in the week. The dry mixture keeps well for up to five days in an airtight container.
- Use frozen cod straight from the bag for savings: Frozen fish is often cheaper and just as good as fresh if thawed properly. Thaw overnight in the fridge, never in the microwave, which can partially cook the edges and make the texture uneven. The fillets should feel cold but pliable, not icy or warm.
Equipment You’ll Need
- 9×13 inch baking dish
- Aluminium foil
- Mixing bowls (one small, one shallow)
- Sharp knife
- Pastry brush or silicone brush
- Kitchen paper
- Box grater (for fresh parmesan)
- Zester or microplane
Common Mistakes to Avoid
- Overcrowding the pan: When fillets are packed tightly together, they release steam that gets trapped between them, softening the crust into a damp, pale mess. Always leave at least 2cm of space around each fillet so hot air can circulate freely and keep the coating crunchy.
- Wrong temperature: Baking at too low a temperature (below 190°C) will dry out the fish before the crust browns, leaving you with tough, overcooked cod. Too high (above 230°C) will burn the parmesan before the fish cooks through. Stick to 200°C fan-assisted for a golden crust and perfectly flaky interior.
- Skipping the rest time: Pulling the fish straight from the oven to the plate means the crust can slide off in one sad, greasy sheet. Letting it rest for three minutes allows the crust to adhere firmly to the fish and the juices to redistribute, so each bite stays intact and moist.
- Using wet fish: If you skip the drying step, the coating will slide right off during baking. The moisture creates a barrier between the fish and the crust, resulting in a patchy, uneven coating that doesn’t crisp properly.
Delicious Variations to Try
- Spicy Version: Add 1 teaspoon of cayenne pepper or smoked chipotle powder to the breadcrumb mixture. For extra heat, drizzle the finished fish with a little hot sauce before serving. The smoky heat pairs beautifully with the nutty parmesan.
- Vegetarian/Vegan Option: Substitute the cod with thick slices of firm tofu or portobello mushroom caps. Use a vegan parmesan alternative (available in most supermarkets) and replace the mayonnaise with vegan mayo. The cooking time remains roughly the same — check for golden crust and tender interior.
- Different Protein: This crust works brilliantly on other white fish like haddock, pollock, or tilapia. For a heartier option, try it on chicken breasts — increase the baking time to 25-30 minutes and check the internal temperature reaches 74°C. The crust adapts beautifully to both options.
What to Serve With Baked Cod with Parmesan Crust
- Steamed tenderstem broccoli or green beans tossed with lemon and butter
- A simple rocket and parmesan salad with a light vinaigrette
- Fluffy couscous or quinoa to soak up any buttery juices
- Roasted baby potatoes or sweet potato wedges for a heartier meal
- For a full meal-prep bowl, pair it with Lemon Garlic Baked Chicken Legs for a protein-packed week of lunches

Frequently Asked Questions
Can I use frozen cod without thawing it first?
I wouldn’t recommend it. Baking frozen cod will release too much water as it thaws in the oven, which makes the crust soggy and the fish cook unevenly. Always thaw frozen fillets overnight in the fridge, then pat them very dry before coating. The extra few minutes of planning are well worth the texture payoff.
How do I reheat leftovers without losing the crunch?
The best method is to reheat the fish in a hot oven or air fryer at 180°C for about 6-8 minutes. Avoid the microwave at all costs — it will turn the crisp crust into a sad, rubbery layer. If you’re reheating from frozen, add two extra minutes to the oven time. The crust will crisp back up beautifully.
Can I make the crust mixture ahead of time for meal prep?
Absolutely. The dry breadcrumb and parmesan mixture will keep in an airtight container in the fridge for up to five days. The wet butter-mayo mixture should be made fresh, as it separates over time. When you’re ready to cook, simply brush the fish with the wet mixture and dip it into the pre-made dry mix. It speeds up weeknight prep considerably.
What’s the best way to store leftover baked cod?
Let the fish cool completely (about 20 minutes at room temperature), then wrap each fillet individually in foil or place them in an airtight container in a single layer. Stored properly, it will keep in the fridge for three days or in the freezer for up to two months. I like to portion them out for quick lunches — just grab a fillet, reheat in the oven, and serve with a simple salad.
Can I use a different cheese instead of parmesan?
Yes, but the texture will change. Parmesan works so well because it’s a hard, dry cheese that crisps up beautifully without becoming greasy. Pecorino Romano is an excellent substitute with a slightly saltier, sharper flavour. Avoid soft cheeses like mozzarella or cheddar, as they will melt into a puddle rather than form a crisp crust.

Notes
Ensure the cod is patted very dry for the best crust adhesion. If the crust browns too quickly during baking, loosely tent the dish with foil. Resting the fish briefly after baking helps the crust set and the fish finish cooking perfectly.
