This salmon and Chinese cabbage gratin soup is creamy, savory, and comforting, with tender vegetables and flaky salmon under a golden cheese topping. White miso and stock add deep flavor, while the light broth keeps the dish cozy without feeling too heavy.
Remove the skin and bones from the salmon, then cut it into bite-size pieces. Toss with 1/2 tbsp cooking sake and set aside for a few minutes while you prepare the vegetables.

Cut the Chinese cabbage core into 1 cm strips and roughly chop the leaves into larger pieces. Slice the Japanese leek diagonally into 1 cm pieces, trim the mushrooms into bite-size pieces, and cut the bacon into small pieces.

Add the bacon, white miso, refined cooking sake, soup stock granules, and about half of the milk to a deep skillet or frying pan over medium heat. Stir until the miso dissolves, then add the cabbage core, leek, and mushrooms. Once they begin to soften, add the cabbage leaves and salmon, and simmer gently for 8 to 10 minutes until the cabbage is tender and the salmon is just cooked through.

Pour in the remaining milk and adjust to your preferred soup consistency. Stir the katakuriko slurry once more, then add it to the pan and simmer gently until the broth lightly thickens. Stir carefully so the salmon pieces stay intact.

Transfer the soup to a heatproof baking dish or individual gratin dishes. Sprinkle the grated cheese evenly over the top, making sure to cover the surface well.

Bake or toast in a toaster oven until the cheese is melted and golden brown. Serve hot while the top is still bubbling.

If you do not have Japanese leek, use a mild regular leek. Shimeji, enoki, or shiitake all work well here. Store leftovers in an airtight container for up to 2 days and reheat gently so the salmon does not overcook.
