This vibrant roast fish with curry butter is a wonderful way to enjoy a heart-healthy supper that is big on flavour. Succulent white fish, such as cod or hake, is tray-roasted alongside caramelised fennel, red onion and golden baby potatoes. The dish is brought to life with a simple yet aromatic infused butter, featuring fresh ginger, garlic and mild curry spice, providing a gentle warmth that perfectly complements the delicate fish.
Suitable for a nutritious midweek meal or a relaxed weekend dinner, this recipe focuses on wholesome ingredients and effortless preparation.

Ingredients for Roast Fish with Curry Butter
1 fennel bulb, sliced
1 large red onion, cut through root end into 8 wedges
450g baby Yukon Gold potatoes, halved if large
3 tablespoons extra-virgin olive oil
Kosher salt
4 tablespoons unsalted butter
2 garlic cloves, crushed
1 (1/2") piece ginger, peeled, finely chopped
1 teaspoon curry powder

How to make Roast Fish with Curry Butter
Preheat oven to 218°C. Toss fennel, onion, potatoes, and oil in a 3-qt. baking dish to coat; season with salt. Roast, tossing once, until vegetables are browned and softened, 35–40 minutes.
Meanwhile, melt butter in a small saucepan over medium heat. Mix in garlic, ginger, curry powder, and a pinch of salt. Simmer until colour intensifies, about 1 minute. Remove from heat.
Season fish with salt and lay on top of cooked vegetables. Drizzle fish with curry butter. Reduce oven temperature to 177°C and bake fish until flesh easily flakes apart with a fork, 12–15 minutes.
Serve vegetables and fish with mint scattered over.
