Preheat oven to 170C (fan forced). Peel potatoes and cut into thin slices.
Grease the baking dish with butter and dust all sides and bottom with bread-crumbs.
Layer potatoes, then season with salt and black pepper, top with a layer of chicken meat sprinkle with a little carrot, cut shallots and onion. Repeat the process until you use all ingredients. The last layer must be potatoes.
Pour the thickened cream over the potatoes, cover with aluminum foil and place in preheated oven, bake for about 1 hours. Remove foil and cook for a further 30 minutes uncovered or until golden brown and the cream has evaporated.
