Method
Heat oven to 200°C (180°C fan). Boil potatoes until soft, about 18 minutes; drain and mash with butter and milk.
Brown the beef mince in a pan; add onion and carrots, and cook 7 minutes.
Stir in flour and tomato purée. Slowly add stock and simmer 15 minutes until thickened. Stir in peas.
Spoon the beef filling into an ovenproof dish. Spread the mash over it and rough up the top with a fork.
Bake 25–30 minutes until golden and bubbling.
Food safety: ensure poultry is fully cooked, handle raw meat separately, and check packaging for allergens. Times are estimates and ovens vary.
