Cook’s notes

You can use any other whole fish like snapper barramundi instead of trout. While the fish is cooking in the oven, prepare a large mixed salad or pan-fry broccoli, carrots, cauliflower and snow peas with some coconut oil, garlic, chilli and lemon juice or white wine. I also add a dollop of butter at the end.

In addition to fish, you could also add some diced vegetables to the roasting tray around the fish. Something like whole shallots, carrots, cauliflower or sweet potatoes would work well. This Spanish pisto vegetable stew would also go well

  1. Oh my god. Baked whole fish is the best. Nothing makes me feel more like a wolf girl than just pulling apart a whole fish for dinner. The cheek is the best bit! NOM!!!!

  2. What a beautiful dish! We had been given a large trout and I wanted to do something really special with it, and this recipe did just that. I served it with mashed cauliflower and parsnip and fine green beans. I forgot to add the mint and onion to the rest of the items that went into the processor, but chopped it finely and added to the surrounds of the fish. The fish got basted with the sauce. Still worked a treat.

  3. I surprised my husband with this. I bought the trout at Costco and did not know what to do with it. I do not like fish. But I did this recipe and he was amazed how good it looked. But the real test was the taste and he LOVED it. Thank you.

  4. Hi Irena, I’m so glad I found your recipe for baked trout; I’ve cooked it many times and it has become a real family favourite, which we cook for special get-togethers or just because we enjoy trout so much and your salsa recipe really enhances the fish. Thank you.

    1. Thank you, Catherine. I really appreciate it. I really need to make this again and maybe take some better photos 😉

  5. We love this and make it several times a year. I’ve tried the salsa with other fish but it just isn’t as good. I’m always searching for interesting dairy free recipes. The trout is delicious!
