Method
Heat oven to 200°C (180°C fan). Boil and mash potatoes with butter and milk.
Brown lamb mince in a wide pan, draining excess fat if needed. Add onion and carrot and cook 7 minutes.
Stir in flour and tomato purée, add stock and simmer until thick, around 15 minutes.
Fold in peas. Put the filling in a baking dish and spread the mashed potato over the top.
Bake for 25–30 minutes until the edges bubble and the top is golden.
Food safety: ensure poultry is fully cooked, handle raw meat separately, and check packaging for allergens. Times are estimates and ovens vary.
