Grilled Cod with Fennel and Orange

This vibrant grilled cod with fennel and orange is a sophisticated high-protein meal that celebrates fresh, Mediterranean flavours. The delicate white fish stays perfectly moist under a citrus-spiked mayonnaise crust, while the fennel and blood orange slices caramelise under the grill to create a sweet and savoury accompaniment. It is a wonderfully light yet satisfying dish that brings a burst of coastal freshness to your dinner table.

Packed with lean protein and fibre-rich white beans, this recipe is an excellent choice for a nutritious mid-week supper. The addition of tenderstem broccoli and toasted almonds provides a lovely crunch, making it a complete one-tray meal that requires minimal tidy-up. Serve it exactly as it is for a healthy, low-carbohydrate lunch or dinner that feels truly indulgent.

Ingredients for Grilled Cod with Fennel and Orange

  • 40g mayonnaise

  • 1/4 teaspoons crushed red pepper flakes (optional)

  • 2 garlic cloves, finely grated, divided

  • 2 teaspoons finely grated orange zest, divided

  • 1 teaspoon kosher salt, divided

  • 4 (170g) skinless cod fillets

  • 1 fennel bulb, very thinly sliced (about 350g )

  • 1 bunch broccolini, trimmed, halved (about 230g )

  • 1 small orange, preferably blood, thinly sliced

  • 1 (450g) can white beans, drained, rinsed

  • 2 tablespoons olive oil

  • 1 tablespoon rosemary leaves

  • 1/4 cup sliced almonds, chopped (about 30g )

Heat grill to high. Mix mayonnaise, red pepper flakes, 1 teaspoon garlic, 1 teaspoon orange zest, and 1/2 teaspoons salt in a small bowl.

Arrange cod fillets on a rimmed baking sheet. Spread mayonnaise mixture over each fillet.

Toss fennel, broccolini, orange, beans, oil, rosemary, and remaining garlic, 1 teaspoon orange zest, and 1/2 teaspoons salt in a large bowl. Arrange around fish on baking sheet, placing orange slices on top of beans and vegetables.

Place baking sheet under grill and grill until fish is golden-brown on top, about 5 minutes. Remove from oven, top each fillet with almonds, then continue to grill until almonds are toasted and crisp and fish is completely cooked through, about 1 minute more.
