Baked lemon pepper cod with roasted broccoli

White fish, broccoli and a bright lemon dressing can turn an ordinary Tuesday dinner into something worth lingering over. This baked lemon pepper cod with roasted broccoli keeps the cooking simple: one tray, one oven and a short list of familiar ingredients, with the seasoned fish at the centre of the plate.

Cod has a mild, almost creamy flavour that welcomes black pepper, garlic and fresh citrus without needing a heavy sauce. Roasting the florets until their edges catch colour gives the meal contrast, while a final squeeze of lemon keeps the finished dish clean, fresh and comforting.

Choose your lemon pepper finish

The basic seasoning is lemon zest, cracked black pepper, garlic and olive oil. Before the fish goes into the oven, decide whether you want a light glaze, a crisp crumb or a little extra heat.

Finish	What to add	What you get
Classic	Lemon zest, garlic, pepper and olive oil	A glossy, aromatic coating with the clean flavour of cod
Panko crust	40 g panko mixed into the seasoning	A crisp, golden edge that contrasts with the soft fish
Chilli warmth	1/2 tsp chilli flakes with the seasoning	Gentle heat that brightens the lemon and pepper

Choose one finish rather than combining all three. The classic version suits a simple family supper, while panko is useful when the fish needs to hold its shape on a shared tray. Chilli works well if you are serving the meal with cool, crisp salad leaves.

Gather fresh, everyday ingredients

Use 500 g cod fillets with the bones removed and about 500 g broccoli. Cut the broccoli into small, evenly sized florets; peel the outer stem, slice it thinly and add it to the tray, as it becomes tender and sweet in the oven. Have one unwaxed lemon, three tablespoons of extra-virgin olive oil, one finely grated garlic clove, one teaspoon of freshly cracked black pepper and half a teaspoon of fine sea salt ready.

Fresh fish is available from independent fishmongers and seafood counters, including shops near Sydney Fish Market and fishmongers at Melbourne’s Queen Victoria Market. Ask the seller to remove any pin bones and choose fillets that look translucent and spring back when pressed. Cod can also be bought frozen; thaw it overnight in the fridge for the cleanest flavour and texture.

Choose broccoli with tight green heads and fresh stems, avoiding florets that have begun to loosen or yellow. Panko breadcrumbs are sold in many Asian groceries and mainstream supermarkets, while flat-leaf parsley is a useful optional garnish. Broccoli is especially satisfying through Australia’s cooler months, roughly May to September, although good fresh heads are available throughout the year.

Prepare the cod and broccoli

Set the oven to 200°C conventional or 180°C fan, a useful distinction because Australian ovens commonly show both settings. Put a roasting tray in the oven to heat while you prepare the vegetables. A metal tray gives the broccoli more colour than a pale ceramic dish, and heating it first helps the florets start roasting rather than releasing excess water.

If the cod is frozen, thaw it slowly in the refrigerator and pat it thoroughly dry with paper towel. Check each fillet for bones and trim away any thin, ragged edges. Mix two tablespoons of olive oil with the lemon zest, garlic, black pepper and salt. Reserve the juice of half the lemon for serving, then brush the seasoning over the fish, coating the top generously while leaving the flesh exposed enough to stay tender.

Toss the broccoli with the remaining tablespoon of olive oil and a small pinch of salt. Keep the pieces separate so their cut sides can brown. If you are making the panko version, combine the breadcrumbs with the seasoned oil, garlic and lemon zest, then press the mixture lightly onto the cod just before it goes into the oven.

Roast until the edges turn golden

Put the hot tray in the oven and roast the broccoli on its own for 8–10 minutes. It should be beginning to colour at the tips but still have some firmness. Turn the largest florets once so they colour evenly, then move the tray carefully; the metal will be extremely hot.

Use a wide metal spatula or your fingertips to make a shallow space among the broccoli. Nestle the cod into the tray, skin-side down if it has skin, and pour any seasoning left in the bowl over the fish. Return the tray to the oven and roast for another 12–15 minutes, depending on the thickness of the fillets.

The cod is ready when the thickest part turns opaque and separates easily into flakes. The broccoli should be tender with browned edges, and a panko crust should look dry and golden rather than pale. Move everything to a warm platter, let the fish rest for two minutes, then add the reserved lemon juice and a little chopped parsley. Taste before adding more salt.

Serve it with fresh, familiar accompaniments

The finished fish is equally at home with roasted potatoes, steamed rice or a mound of quinoa. A spoonful of plain yoghurt or a drizzle of tahini softens the pepper, while a cucumber and tomato salad adds coolness. For an Australian-style dinner, serve the tray in the middle of the table with lemon wedges, extra olive oil and plenty of warm vegetables alongside.

Keep the portions light enough for a warm evening, but choose accompaniments that contrast with the cod’s delicate texture. Brown rice works especially well with the roasting juices, as does warm flatbread for catching the seasoned oil. Fresh parsley, coriander or chives can provide a green finish without competing with the lemon.

Make the side dishes according to the season. Through winter, add roast pumpkin or sweet potato; in spring, choose broad beans or green peas; through summer, a salad of tomatoes, cucumber and herbs will suit the plate. Australia’s varied growing conditions mean the best choice depends on your local growers and the week’s weather more than on a fixed calendar.

Adapt the recipe and make it your own

For a richer meal, put the cod beneath a thin layer of sliced leeks and grated cheese before roasting, adding the cheese for the final five minutes so it melts without becoming rubbery. Cauliflower can replace half the broccoli, or parsnip and carrot can be roasted alongside it for an earthier plate. To keep the dish gluten-free, leave out the panko and use extra lemon zest and cracked pepper for a more pronounced citrus finish.

Keep leftovers in an airtight container in the fridge and eat within two days. Reheat the cod gently with a splash of water or stock in a covered pan, and roast or microwave the broccoli separately so it does not turn soft. If the fish smells strongly after storage, discard it rather than relying on lemon or seasoning to mask it.

Save this recipe for your next midweek meal, add cod, broccoli and a lemon to the shopping list, and enjoy the simple pleasure of a well-seasoned dinner from the oven.
