Baked Cod Lemon Herb Butter

I was standing at the fishmonger's counter on a rainy Tuesday, staring at the glistening cod fillets and wondering how to make dinner feel special without spending an hour in the kitchen. The idea came from a scribbled note my neighbor had left me years ago: butter, breadcrumbs, lemon, done. I bought four fillets, grabbed a lemon on the way out, and by the time the oven timer rang, my kitchen smelled like a seaside bistro.

The first time I made this for my sister, she looked skeptical when I said it would be ready in under forty minutes. But when she broke into that buttery, golden crust with her fork and tasted the bright lemon and herbs against the mild fish, she went quiet for a moment, then asked for the recipe. That's when I knew this dish had staying power.

Ingredients

• Cod fillets: Look for thick, firm fillets without any fishy smell, and always pat them completely dry so the crumb mixture sticks beautifully.
• Unsalted butter: Melted butter binds the crumbs and adds richness, and using unsalted lets you control the seasoning perfectly.
• Fresh breadcrumbs: They toast up lighter and crispier than dried ones, and you can make them in seconds by pulsing day old bread in a food processor.
• Lemon zest and juice: The zest gives fragrant oil and the juice adds just enough acidity to cut through the butter without making anything soggy.
• Fresh parsley and dill: Parsley is bright and grassy, dill is gentle and aromatic, together they make the topping taste alive.
• Garlic clove: One small clove minced fine disappears into the crumb but leaves a warm, savory undertone.
• Salt and black pepper: Simple seasoning that lets the fish and herbs shine without competing.

Instructions

Prepare your oven and tray:

Set the oven to 200°C and line a baking tray with parchment so cleanup is effortless. If you are using a dish, a light brush of oil or butter will do the trick.

Dry and arrange the cod:

Use paper towels to blot every bit of moisture from the fillets, then lay them out with a little space between each one. Dry fish means the topping will cling and crisp instead of steam.

Mix the crumb topping:

Pour melted butter into a bowl, add breadcrumbs, lemon zest, juice, herbs, garlic, salt, and pepper, then stir until it looks like damp sand that clumps when you pinch it. Taste a tiny bit and adjust seasoning if needed.

Top the fillets:

Spoon the crumb mixture generously over each piece of cod, pressing gently with the back of the spoon so it adheres. Don't worry if it looks like a lot, it will settle and toast beautifully.

Bake until golden:

Slide the tray into the oven and bake for 15 to 20 minutes, watching for the moment when the crumbs turn golden brown and the fish turns opaque and flakes easily with a fork. The smell will tell you when it is close.

Garnish and serve:

Pull the tray out, sprinkle fresh parsley over the top, tuck lemon wedges alongside, and serve while everything is still hot and fragrant.

Pin it

One evening I served this with buttery new potatoes and green beans, and my friend said it reminded her of a meal she had on the coast of Cornwall years ago. She swore she could taste the sea air. I didn't tell her it was just supermarket cod and a Tuesday night, because sometimes a dish can carry you somewhere else without a plane ticket.

Choosing and Storing Your Fish

Fresh cod should smell clean and briny, never fishy or sour, and the flesh should be translucent and firm to the touch. If you are buying frozen, let it thaw slowly in the fridge overnight so it stays tender, and always drain off any liquid before patting it dry. I have learned that taking an extra minute to inspect and prepare the fish properly makes the difference between a good dinner and a great one.

Swapping the Fish or Adding Flavor

Haddock, halibut, or even thick tilapia fillets work beautifully here, as long as the fish is firm enough to hold up under the crumb. If you want a little heat, add a pinch of chili flakes to the topping, or stir in a tablespoon of grated Parmesan for a savory, nutty edge. I once added a spoonful of Dijon mustard to the butter and it gave the whole dish a subtle sharpness that my dad could not stop talking about.

Serving Suggestions and Sides

This cod feels at home next to roasted vegetables, steamed asparagus, or a pile of buttery mashed potatoes, but it is just as happy perched on a bed of dressed greens or alongside a lemony couscous. The key is keeping the sides simple so the bright, herby crumb stays the star.

• Try serving with roasted cherry tomatoes for a pop of sweetness and color.
• A crisp white wine or sparkling water with lemon makes the whole meal feel a little more special.
• Leftovers are excellent flaked into a salad or tucked into a wrap the next day.
