Ingredients update with servings
- Cooked chicken (shredded or chopped) – 400 g
- Potatoes (thin sliced) – 600 g
- Condensed cream of chicken soup – 300 g
- Milk – 120 ml
- Cheddar cheese (grated) – 200 g
- Garlic (minced) – 10 g
- Black pepper – 2 g
- Butter (for dish) – 10 g
- Dijon Mustard – 1 tsp (optional)
- Pinch of herbs of choice
Method
13 steps- Preheat oven to 180°C (fan 160°C).
- In a bowl, mix together the condensed cream of chicken soup, milk, black pepper, Dijon mustard (if using), and a pinch of herbs.
- Grease a 9x13 or 9x11 inch baking dish with butter.
- Layer sliced potatoes on the bottom of the dish, slightly overlapping.
- Sprinkle some minced garlic, then some shredded chicken, then a little grated cheese over the potatoes.
- Drizzle a little of the soup mixture over the layer.
- Repeat layers with remaining potatoes, garlic, chicken, cheese, and soup mixture, finishing with a layer of potatoes on top.
- Pour the remaining soup mixture over the top layer of potatoes.
- Sprinkle the remaining grated cheese on top and add a little extra black pepper if desired.
- Cover the dish loosely with foil, tenting it so it doesn't touch the cheese.
- Bake in the preheated oven for 40 minutes.
- Remove the foil and bake for another 20–25 minutes, or until the top is golden and bubbling and a knife inserted into the potatoes goes in easily.
- Let rest for 5 minutes before serving.
Recipe notes
Helpful tips
- Use rotisserie or leftover cooked chicken to save time.
- Slice potatoes to roughly even thickness so they cook evenly.
- Tent the foil loosely so it steams the potatoes without touching the cheese.
- Check doneness by inserting a knife into the potatoes; it should go in easily.
- Let the gratin rest for 5 minutes before serving for easier slicing.
Equipment
- 9x13 or 9x11 inch baking dish
- Mixing bowl
- Knife
Storage
Store leftovers covered in the refrigerator for up to 3–4 days. Reheat gently in the oven or microwave until piping hot.
Additional tips
- The condensed cream of chicken soup is very salty; the source deliberately omitted added salt. Use a low-sodium soup if you prefer to add salt. Handle the hot dish carefully when removing the foil.
