Slow-Roasted Salmon with Fennel, Citrus, and Chillies

This slow-roasted salmon with fennel, citrus, and chillies is a vibrant and aromatic dish that celebrates fresh flavours. By cooking the fish gently in olive oil at a lower temperature, the salmon retains a beautifully buttery, melting texture that contrasts perfectly with the softened fennel and bright citrus slices. The addition of fresh chilli provides a subtle heat that cuts through the richness of the oil, making every bite balanced and sophisticated.

As a heart-healthy main course, this recipe is packed with omega-3 fatty acids and antioxidants from the fresh produce. It is an excellent choice for a light weekend lunch or a stress-free dinner party, as the gentle roasting method is very forgiving. Serve it in large flakes alongside some steamed seasonal greens or a crisp green salad for a complete, nourishing meal.

How to make Slow-Roasted Salmon with Fennel, Citrus, and Chillies

Preheat oven to 135°C. Toss fennel, orange slices, lemon slices, chilli, and 4 dill sprigs in a shallow 3-quart baking dish; season with kosher salt and pepper. Season salmon with kosher salt and place on top of fennel mixture. Pour oil over.

Roast until salmon is just cooked through (the tip of a knife will slide through easily and flesh will be slightly opaque), 30–40 minutes for medium-rare.

Transfer salmon to a platter, breaking it into large pieces as you go. Spoon fennel mixture and oil from baking dish over; discard dill sprigs. Season with sea salt and pepper and top with fresh dill sprigs.
