Celery Root Bisque with Thyme Croutons

This elegant celeriac bisque is a wonderful way to celebrate the subtle, nutty flavour of one of the season’s most versatile root vegetables. Often overlooked for its rugged appearance, celeriac transforms into a silky, sophisticated soup when simmered with fragrant shallots and earthy fresh thyme. The addition of a small amount of potato provides a velvet-smooth texture without the need for heavy thickeners, making it an excellent choice for a refined dinner party starter or a comforting weekend lunch.

As a dairy-free dish, this recipe relies on the natural starch of the vegetables and a touch of cream to achieve its luxurious consistency. If you are preparing for guests, the soup can be made up to two days in advance and gently reheated, allowing the herbal notes to develop further. Serve it in warmed bowls with a sprinkle of fresh herbs and some crusty bread for a truly satisfying homemade meal.

How to make Celery Root Bisque with Thyme Croutons
