Ingredients
- 70g saved plain cooked chicken from Dinner 1
- 1¾ potatoes, thinly sliced
- ¼ onion, finely sliced
- 1 courgette or carrot, thinly sliced or grated
- ¼–½ garlic clove
- 55ml extra-thick cream or double cream
- 60ml low-salt or no-salt stock or water
- 15g parmesan or Italian hard cheese
- 10g optional mild cheddar
- ¼ tsp dried thyme or small sprig fresh
- Small pinch rosemary, very finely chopped
- 5ml rapeseed or olive oil
- 20g plain yoghurt, optional for baby or toddler portion
Method
- Heat oven to 190°C / 170°C fan.
- Thinly slice potatoes. Slice onion and courgette, or grate carrot if using.
- Heat oil in a pan. Cook onion for 5 minutes until softened. Add garlic, thyme and rosemary for 30 seconds.
- Add cream and stock or water. Warm gently.
- For baby portions, set aside a little plain cooked chicken, soft cooked potato and veg and yoghurt or cream before adding cheese.
- Layer potatoes, veg and shredded cooked chicken in a baking dish.
- Pour over the cream mixture. Cover with foil.
- Bake for 25–30 minutes, then uncover, sprinkle parmesan and cheddar over adult and older-child sections if using, and bake for another 10–15 minutes until potatoes are soft and the top is golden.
- Rest for 5–10 minutes before serving.
Storage and reheating
Cool cooked chicken and creamy sauces within 2 hours. Refrigerate cooked chicken and creamy dishes for up to 48 hours. Reheat until steaming hot throughout and only reheat cooked chicken once. Pasta is best fresh, but sauce can be chilled separately. For babies and toddlers, keep portions separate before adding salt, regular stock, parmesan, cheddar, sun-dried tomatoes, chilli or adult sauces.
Safety and substitutions
Reheat leftover chicken only once until steaming hot throughout. Potato gratin holds heat, so cool before serving children. Avoid salty cheese, stock-heavy sauce and browned crusts for babies.
