Ingredients

2 Tbsp.
vegetable oil
1 tsp.
mustard seeds
1 tsp.
mild chilli powder
1 tsp.
ground turmeric
1 tsp.
cumin seeds
1 tsp.
ground coriander
3 Tbsp.
mild curry spice paste, we used Patak's

tin chickpeas
4
cod fillets, skinless, around 125g each
Fresh coriander, roughly chopped, to serve

Directions

1. Step 1Preheat oven to 200°C (180°C fan) mark 6. In a small bowl, mix the oil, spices, curry paste and plenty of seasoning.
2. Step 2Pour all but 1tbsp of the mixture into a large roasting tin. Add the sweet potato, red onions, cauliflower and tomatoes to the tin and stir to coat in the spice mixture. Roast for 30min, tossing midway through, until the vegetables are tender.
3. Step 3Stir through the chickpeas and place the cod on top. Spoon the reserved spice mixture over the cod and return to the oven for 10min, or until the fish is cooked and flakes when gently pressed. Sprinkle with coriander and serve.

Did you know that you can freeze leftover curry paste? Simply pop into an ice cube tray and freeze fully. Then you'll have portioned cubes of curry paste ready to add into your next meal to boost the flavour.

We've used a mild curry paste in this traybake recipe but you can experiment with different pastes depending on what you might have in the fridge already, or the flavour profile you're going for.

Salmon or seabass fillets would also work well in place of the cod.
