This carrot soup with thyme and fennel is a wonderfully fragrant and comforting dish that celebrates simple, wholesome ingredients. The natural sweetness of the carrots is beautifully balanced by the delicate aniseed notes of fennel seeds and the earthy depth of fresh thyme. Slowly sweating the leeks and onions ensures a rich, savoury base that feels indulgent while remaining light and nutritious.
As a diabetes-friendly recipe, this soup is high in fibre and uses low-salt broth to keep it heart-healthy without compromising on flavour. It is an excellent choice for a batch-cook lunch or a starter for a family dinner. Serve it with a small portion of wholegrain bread for a balanced, satisfying meal that is both easy to prepare and kind to your blood sugar levels.
