There's a particular satisfaction in getting a fish crust right – that moment where you lift the lid on the oven and the top has gone properly gold rather than the sad, pale beige you get if you rush it. This parmesan crusted cod took a few goes to nail at Casa Adora, but the oven here runs true at 190°C, so once you've found the timing it stays reliable, which is more than I can say for most things in this kitchen.

The crust itself is nothing clever – breadcrumbs, parmesan, garlic, a whisper of smoked paprika – but pressed onto a well-dried fillet and given twelve honest minutes, it turns into something that crackles under the fork while the cod underneath stays properly moist. No sauce required. No faff. Just a crisp top and a good fillet doing what a good fillet should do.

Ingredients for Parmesan Crusted Cod

For the topping

• Breadcrumbs – 20 g
• Parmesan, finely grated – 15 g
• Garlic, 1 clove, microplaned
• Olive oil – 1 tbsp
• Smoked paprika – ¼ tsp
• Sea salt and black pepper, to taste

For the fish

• Cod fillet, 1 portion
• Olive oil, for brushing
• Sea salt, for seasoning

Method

Make the crust. Mix the breadcrumbs, parmesan, garlic, olive oil, smoked paprika, salt and pepper together until it forms a lightly oily crumble – you want it to hold together when pressed, not sit there as dry dust.

Heat the oven. 190°C. If your oven runs a bit hot or cold, this is the one recipe where it's worth knowing which way yours leans.

A quick word on the fillet itself: mine came frozen, so it spent 24 hours defrosting slowly in the fridge – no shortcuts, no lukewarm water bowls – before being patted properly dry with kitchen paper and left to come up to room temperature. It's not a glamorous step, but it matters more than people think: a fillet that's still cold and damp in the middle won't crisp the same way, however good your crust is.

Dry the fish. Pat the cod fillet dry, salt it lightly, and leave it for 5 minutes. This isn't a step to skip – a wet fillet steams instead of crisping, and the crust won't hold as well either.

Oil and crust it. Brush the top of the fillet with olive oil, then press the crumb mixture firmly onto the top only – leave the underside bare.

Bake. 12 minutes. Check the colour: if you want it deeper gold, give it another 2–3 minutes, but keep an eye on it, because that's the difference between crisp and burnt-crumb bitterness.

Rest. 2 minutes before serving, so the crust settles and the fillet finishes gently rather than tearing apart under the fork.

Notes

I served this with a bright, blitzed pea purée and a sharp pepino salad on the side – both good foils for the richness of the crust.

If you want extra lift on the plate, a tiny grate of lemon zest over the finished cod does the job without overcomplicating what is, at heart, a very simple bit of cooking.
