4 cod fillets (approx 150g each)
1/2 tbsp extra virgin olive oil
2 tbsp Cajun seasoning
1/4 tsp salt
1/4 tsp black pepper
3 tbsp unsalted butter (sliced)
1 lemon (cut into wedges)
250g baby plum tomatoes (halved)
200g fine asparagus (trimmed)
2 cloves garlic (finely diced)
1 tbsp extra virgin olive oil
1/4 tsp salt
1/8 tsp black pepper
fresh parsley (finely diced, for serving)

Directions

Preheat your oven to 200°C (400°F).
Line a large baking tray with parchment paper. Add the tomatoes, asparagus, garlic, salt, and pepper. Drizzle with olive oil and toss until evenly coated.
Pat the cod fillets dry with paper towels and place them on a plate. Brush with olive oil, then season with Cajun seasoning, salt, and black pepper. Coat the sides well.
Place the seasoned cod fillets onto the tray among the vegetables. Top each fillet with slices of butter.
Bake for 10–12 minutes, or until the cod is opaque and flakes easily with a fork.
Serve with the roasted vegetables and a lemon wedge. Garnish with fresh parsley, drizzle with pan juices, and squeeze lemon juice over the top to taste.

Servings and timing

Variations

You can swap cod with other white fish like haddock or tilapia. For extra heat, add a pinch of chili flakes or cayenne pepper. If you prefer a milder flavor, reduce the Cajun seasoning and add paprika instead. You can also include other vegetables like zucchini or bell peppers for more variety.

Storage/Reheating

Store leftovers in an airtight container in the refrigerator for up to 2 days. To reheat, place the fish and vegetables in an oven-safe dish and warm at 170°C (325°F) until heated through. Avoid overcooking to keep the fish tender. You can also microwave it in short intervals.
