Mushroom and Leek Soup with Thyme Cream

This elegant mushroom and leek soup with thyme cream is a sophisticated take on a classic winter warmer. By slowly browning baby bella mushrooms and softening leeks in butter, the dish develops a deep, savoury base that is perfectly balanced by the earthy notes of fresh thyme. The addition of a light, herb-infused cream provides a luxurious finish, making this soup feel special enough for a dinner party starter while remaining simple enough for a midweek meal.

As a high-protein option, this satisfying soup is surprisingly filling and serves as an excellent homemade alternative to tinned varieties. The recipe is highly practical, as the soup can be prepared up to two days in advance and reheated, while the thyme cream develops its best flavour when left to infuse overnight. Serve it alongside some crusty sourdough bread for a truly comforting and nutritious lunch.

Using electric mixer, beat cream just until soft peaks form. Fold in 2 teaspoons thyme. Cover and refrigerate at least 2 hours to blend flavours. (Thyme cream can be made up to 1 day ahead. If cream separates, whisk until soft peaks re-form. ) Remove from refrigerator 1 hour before serving to come to room temperature.

In 4-quart stock pot over moderately high heat, heat 2 tablespoons butter until hot but not smoking. Working in 2 batches (add 2 more tablespoons butter before second batch), cook mushrooms, stirring occasionally, until lightly browned, about 8 minutes. Transfer to large bowl.

In same stock pot over moderate heat, heat remaining 2 tablespoons butter. Stir in leeks, cover, and cook, stirring often, until soft, about 5 minutes. Add cooked mushrooms, sprinkle with flour, and stir until flour is evenly distributed. Stir in stock, then salt, pepper, and remaining 1 teaspoon thyme. Bring to boil, stirring often, then reduce heat to low, set lid ajar, and simmer 20 minutes. (Soup can be made up to 2 days ahead and refrigerated, covered. Reheat before serving.)

Divide soup among 8 bowls and top each portion with dollop of thyme cream. Serve immediately.
