A weeknight roast haddock dinner that's ready to eat in 45 minutes.

Haddock is a great fish for roasting. The fillets are large and meaty, and the mild flavour is perfect with the earthy potatoes and piquant plum tomatoes. Apart from par-boiling the potatoes, everything here is cooked in one roasting tray so it's really easy to make. It's a great family dinner. If you need more portions it's easy to squeeze a couple extra into the tray. Plus it's healthy too - low in fat and under 400 calories for a complete meal. Keep a close eye on the timings once you have added the fish to the roast as you can overcook haddock, making it a little tough.

Top tips for making roast haddock

Try to get sustainably caught haddock - look out for the Marine Conservation Society's logo on packets, or check out their Good Fish Guide for more info. Alternatively use European hake, which is currently on their 'Best Choice' list.

Add some whole garlic cloves, still in their skins, at the same time as the potatoes if you like them. You can pop the softened cloves out of their skins to eat them when they are roasted.
