A simple, flavourful, lighter dinner, all cooked on a couple of trays in the oven. This Cajun cod recipe is served up with smoky potato wedges (no par-boiling required, and we’re not even peeling the potatoes!). It’s on the table in 40 minutes!
“I cooked this for a small family gathering, I took a risk because 2 people only usually like fish in batter. I think we have converted them to try more fish dishes. Safe to say it was a huge success, thank you.”

Nicky’s Notes

We’re letting the oven do most of the work with this simple, slightly spicy Cajun cod dinner. There’s no searing or par-boiling required – the potato wedges and cod are simply coated in spices and oil, then baked until tender.
The key is to give the potato wedges their 20-minute head start before adding the fish. Cod cooks quickly, and around 10–12 minutes is usually enough for chunky fillets to cook through while still staying lovely and juicy.
I use cod most often, but haddock, hake and pollock all work well too, and salmon is a great option if you fancy something a little richer. Just bear in mind that thicker fillets may need an extra minute or two in the oven.
And don’t be shy with the Cajun seasoning, that smoky, slightly spicy coating is what turns a very simple fish dinner into something we really look forward to.

Pro Tips
Swap out the cod for any chunky white fish, such as pollock, hake or haddock. It also works well with salmon.
Such a great way to pack a flavour punch with minimal effort!
