Roasted Cauliflower with Onions and Fennel

This roasted cauliflower with onions and fennel is a sophisticated vegan side dish that celebrates the natural sweetness of caramelised brassicas. By searing the vegetables in a frying pan before roasting, you develop a deep, savoury flavour and a golden colour that oven-roasting alone cannot achieve. The fragrant marjoram and whole garlic cloves infuse the oil, creating a Mediterranean-inspired aroma that pairs beautifully with the aniseed notes of the fresh fennel bulbs.

Whether you are looking for a healthy accompaniment to a Sunday roast or a substantial base for a plant-based warm salad, this recipe fits the bill perfectly. It is a versatile dish that works just as well served hot from the oven as it does at room temperature. For a complete meal, try serving it alongside some protein-rich pulses or a zestily dressed quinoa.
