    Step 1

    Prepare ingredients

    For more than four servings, repeat batches of no more than four, dividing displayed ingredients and measured method totals between batches. Keep pan sizes and per-batch cooking times fixed; allow extra elapsed time. Heat the oven to 200°C conventional / 180°C fan. Slice scrubbed potatoes 5mm thick, halving across first if more than 4cm wide. Halve tomatoes and chop parsley. Make fresh soft breadcrumbs from weighed white bread. Measure 2g lemon zest and 30ml juice. Pat fully thawed cod dry, check for bones and keep chilled; portions should be about 150g each and no more than 2.5cm thick.

    Add tomatoes and cod

    Divide all tomatoes between the trays and roast for 10 minutes more. Make space for the cod on each tray, coat all fish with remaining 5ml olive oil and add to the trays without overlapping. Roast for 15–18 minutes until the thickest centres are opaque and flake readily. Check potatoes are knife-tender; if either component needs longer, move the finished food to a warm plate and continue cooking the other.
