Fennel and Carrot Confit

This elegant fennel and carrot confit is a sophisticated low-sugar side dish that celebrates the natural sweetness of root vegetables. By gently poaching the thinly shaved carrots and fennel in a lemon-infused olive oil, the vegetables soften into a buttery texture without losing their vibrant colour. A subtle hint of cayenne pepper provides a gentle warmth that balances the aniseed notes of the fennel and the citrusy brightness of the lemon zest.

Perfect for those seeking a light yet flavourful accompaniment, this dish fits beautifully into a heart-healthy or low-carbohydrate diet. The aromatic vegetables are best served at room temperature, making them an excellent choice for a dinner party starter or as a topping for grilled sea bass. You can even reserve the flavoured oil to use as a base for future salad dressings or for drizzling over steamed greens.

Ingredients for Fennel and Carrot Confit

  • 2 medium carrots

  • 1 small fennel bulb, stalks discarded

  • 300ml olive oil

How to make Fennel and Carrot Confit

Shave carrots with a vegetable peeler into very thin, wide ribbons. Quarter fennel bulb lengthwise, then very thinly slice lengthwise.

Heat oil with cayenne, 1/2 teaspoons salt, and 1/4 teaspoons pepper in a 1-quart heavy saucepan over low heat until warm.
