Method
Heat oven to 210°C (190°C fan). Line a large roasting tray; spread potatoes and vegetables out in a single layer.
Toss with olive oil, seasonings and flavour ingredients, using only the zest initially if adding lemon.
Roast the vegetables for 20–25 minutes, turning halfway.
Place salmon fillets over the vegetables; roast another 12–15 minutes, until the fish is opaque and flakes easily.
Finish with lemon juice if using and serve hot.
Food safety: ensure poultry is fully cooked, handle raw meat separately, and check packaging for allergens. Times are estimates and ovens vary.
