Potato soup with onions
6 servings
30 minutes
Potato soup with onion is a delicate and velvety dish rooted in Japanese cuisine. Its base is aromatic leeks and potatoes, giving the soup a rich flavor with a hint of sweetness. The soup has a special texture thanks to potato starch and butter, creating softness and silkiness. Cream adds refinement, while chicken broth deepens the flavor. The dish is perfect for a cozy family dinner or leisurely lunch. Serving it with swirls of cream and fresh chives makes it not only tasty but also aesthetic. It warms on cool days and provides a sense of comfort.

1
Cut off and discard the roots and dark tops of the leek, leaving only a bit of the green part. There should be 700–800 g of leek left. Cut it in half lengthwise, then slice it thinly crosswise. Rinse the leek strips well in cold water and dry them. Peel the potatoes (300–350 g should remain after peeling) and rinse. First slice them, then cut into thin slices. Do not wash the slices — the starchy mixture will thicken the soup.
