Cream of Potato Soup with Open-Faced Cheese Toast, Cherry Tomato, and Cucumber

Headnote

This is a restrained, nourishing composition in which the sweetness of onion and potato is lifted by milk and cream, then sharpened by a simple garnish of fresh tomato and cucumber. The open-faced cheese toast brings salt, richness, and structure, while the soup remains smooth, pale, and quietly luxurious. It is a dish of balance: soft against crisp, warm against cool, and rich against clean.

Wheat flour: 8 g
Water: 180 g
Milk: 120 g
Cream: 25 g
Salt: 3 g
Black pepper: 0.5 g

For the open-faced cheese toast
Wheat bread: 50 g

Vegetable oil: 4 g

Method

1. Place the potato in a saucepan with the water and 1 g of the salt. Bring to a gentle boil over medium heat, then reduce to a steady simmer and cook for 12 to 14 minutes, until the potato is completely tender and just beginning to break at the edges.

2. In a second saucepan, warm the butter over medium-low heat. Add the onion and cook for 5 to 6 minutes, stirring occasionally, until soft, translucent, and sweet without coloring.

3. Add the flour to the onion and butter. Cook for 1 minute, stirring constantly, until the mixture smells lightly nutty and no raw flour remains.

4. Add the milk gradually, whisking until smooth. Add the cooked potato with its cooking liquid, then simmer gently for 6 to 8 minutes, stirring often, until the soup is lightly thickened and the potato is fully integrated.

5. Add the cream, remaining salt, and black pepper. Blend the soup until perfectly smooth, or pass it through a fine sieve for a more refined texture. Return it to low heat and hold just below a simmer; the finished soup should be velvety, pale, and cohesive.

6. Heat the vegetable oil in a small pan over medium heat. Brush the bread lightly with the softened butter, then place it in the pan and toast one side for 1 to 2 minutes until golden. Turn it, cover the toasted side with the grated cheese, and cook for 2 to 3 minutes more, or place under a hot grill briefly, until the cheese is melted, bubbling, and lightly browned at the edges.

7. Combine the cherry tomato and cucumber just before serving. Keep them crisp and fresh; they should remain cool and clean in flavor.

Plating and serving

Ladle the soup into a warm bowl. Set the open-faced cheese toast alongside, not submerged, so its crisp base remains intact. Arrange the cherry tomato and cucumber neatly beside the toast, allowing the plate to read as composed and deliberate, with the soup as the central element.

Professional notes

Do not allow the soup to boil after the cream is added; it must remain smooth and stable. The toast should be deeply golden beneath the cheese, with the cheese fully melted but not hardened. The garnish must be added at the last moment so its freshness cuts through the richness of the soup and toast.
