4 servingservings


  • 1 tbsp 1 tbsp butter or olive oil, for greasing the baking dish
  • 1½ lbs 650 g salmon or white fish, in pieces
  • salt and pepper
  • 4 tbsp 4 tbsp butter or ghee
  • 2 tbsp 2 tbsp red curry paste or green curry paste
  • 2 cups 475 ml canned, unsweetened coconut cream
  • ½ cup 125 ml fresh cilantro, chopped
  • 1 lb 450 g cauliflower or broccoli


Instructions are for 4 servings. Please modify as needed.

  1. Preheat the oven to 400°F (200°C). Grease a medium-sized baking dish.
  2. Place the fish pieces snuggly in the baking dish. Salt and pepper generously and place a tablespoon of butter on top of each fish piece.
  3. Mix coconut cream, curry paste and chopped cilantro in a small bowl and pour over the fish.
  4. Bake in the oven for 20 minutes or until the fish is done.
  5. In the meantime, cut the cauliflower into small florets and boil in lightly salted water for a couple of minutes. Serve with the fish.


If you can't find coconut cream in your grocery store you can use canned coconut milk, but then use two cans. Let the cans sit in the refrigerator for a few hours or over night. Carefully open the cans and scoop out the coconut cream that will have solidified on top.

Don't use the thinner coconut water from the can for this recipe, but don't throw it out either. You can save it and use in smoothies and other refreshing drinks.

    After 10 weeks of keto I have lost 15lbs woohoo loving all the dishes

    For this weeks menus I decided it would a good idea to go back to the two week challenge recipes

    The first time I made this dish I used coconut milk not coconut cream as the cream seemed to be a solid mass ( i had never cooked with coconut cream before)

    It was a disappointment but yesterday I cooked it with coconut cream and it was delicious and now ticked as a favourite :-)

  2. Zen
    I don’t like coconut and fish is there a way I can change the whole dish
  3. Dee
    Is the coconut cream supposed to be sweetened or unsweetened? I screwed up and used cream of coconut the first time and just realized it. 🤦🏻‍♀️
  4. Tra y
    I messed up I guess because the dish said low carb Keto and my meal is very sweet and the coconut cream says 18 carbs which I didn't look at when taking off the shelf.

    Amazing dish, but I guess I grabbed the sweetened cream

  5. Lucy
    OMG..This is beautiful. I wasn’t looking forward to it, as I thought it wouldn’t be nice. I was pleasantly surprised. One of my favourite meals.
  6. Amanda
    This was SO good. And so easy to prepare. Probably the easiest dish to throw together so far that I've tried on here, and the flavor was amazing. Loved it!
  7. Robin
    I'm SO bummed! I didn't read the comments about the Coconut cream vs cream of coconut and I used the latter. I made it, saw that it was very runny, took one very sweet bite and looked at the can and saw 18gms carbs! Now two beautiful salmon filets and all the ingredients that went into making it are going down the garbage disposal! Please put a note in the recipe about this!
  8. Rachel M
    Could i use coconut milk instead of cream?
  9. Janice
    Don't use creamed coconut! I especially went out to buy some - mine came in a packet and not in a can. It's not the same as coconut cream. sauce is really powdery and thick. I even added water to thin it out. I can see it would be tasty with the right type of coconut. You need to be clearer.
  10. Chantel
    If I can't find curry paste can I use curry power instead?
  11. Natalia
    I don't like curry can I switch the curry out for maybe a tomato paste or even a cream cheese?
  12. Tanji
    People are CLEARLY NOT reading your instruction and it so sad!

    Well Tanji why don’ you enlighten us 🤔I think I know what we all did wrong ....friend as you did and I did the mistake and since Tanji wasn’ t kind enough to tell us only shame us what we did wrong I will explain ....As so many made this mistake ....we thought that the refrigerating was only for the coconut cream to scope out the water ..I thought the further instructions about draining the water was only for the cream The directions were not very clear on that . I thought yes they gave us a substitute but didn’t clearly explain that the milk had to be drained of water also 😤. It had an awesome favor but more like a soup 🤣🤣
  14. Mona
    lol. Was thinking the same thing!
  15. Arty
    I can't stomach coconut. What can I use to replace coconut everything?
  16. Scott
    We used a can of coconut milk, the sauce was a little thin but still had good flavor and once you roll your cauliflower around it in you won't be one bit disappointed.
  17. Arty
    Thank you Scott, but I can't stand the taste of coconut. I can taste coconut water, milk, oil etc. in most foods. I notice that coconut is used in a lot of the recipes. I made the fish dish with heavy cream and it was good. I truly appreciate your response.
  18. Jo
    Absolutely love this recipe. Quick and so tasty. But why is it 880 calories per portion?? I can't work it out.

    I started Keto 25th June so just over 4 months I started at 208lbs I am down to 178lbs

    My wife needs to lose weight too but dosn't stick to less than 20g carbs a day she hasn't lost any weight

    I have no idea how to convince her to adopt Keto anymore perhaps she needs a real kick up her backside from someone hehe

  20. Andrew
    Ooops meant to say this recipe is delicious and we are having it tonight
  21. Andrew
    on Keto you don't need to count calories lots of information on the website as to why not but as an example 100calorie piece of fish vs 100 calorie bar of chocolate are they equal ? of course not
  22. Noel
    One of the nicest meals for such a long time. Delicious
  23. Stephanie
    Look in the Asian isle for the unsweetened coconut cream. The one by the drink mixers is sweetened and has a lot of sugar. The one in the Asian isle has 1g carb
  24. Susan
    All these dishes have been fabulous. Quick and easy to prepare.....a joy for a working woman!
    Lets hope the weight loss goes with it to!
  25. Glen
    This recipe is outstanding. Great flavor! I suggest putting cauliflower florettes into pan and I also added sliced shiitake mushrooms. Baking w/ fish at 400 degrees came out perfectly cooked.
  26. Andrew
    This smelled delicious, but despite using the specified amount of curry paste and coconut cream, the sauce was very thin and bland.
  27. Alyona
    880 cal per serving? Did the OP mean whoile dish?
    Yes, i know we dont count calories, but its always good to have some estimate
  28. Anelya
    This was a great dish! I put cauliflower in the casserole too, baked it for a bit longer, and added shredded mozzarella on top. It was yummy, easy and my boyfriend went for seconds! Saving it to my recipe book
  29. Jennifer
    I made this with scallops. It was delicious. I made the sauce in a sauce pan, stirring until thick. Then I sautéed the scallops on butter. I poured the sauce over the scallops. My husband loved it
  30. Barbara
    We liked this. The sauce (made with coconut cream) was not thick, but it was delicious and mild. Not really a "coconutty" taste, or even a strong curry taste (I used store-bought green curry paste). We liked the piquant flavor of the cilantro. I used two large fillets of tilapia, and the two of us ate the whole dish. I think Jennifer (just above) has a good idea to stir the sauce separately until a bit thicker.

    Hi! I joined the Diet Doctor team in October 2018 to answer questions here on the website. I didn't go back and answer all of the old questions but if you have a question now, I will answer it!

    I couldn’t find coconut cream, but did fine creamed coconut. It isn’t sweetened and is one carb per tablespoon. Is this okay to use or no?

    It sounds like that will work well!

  35. Jeanette
    Made this tonite using coconut milk chilled in the fridge then skimming the cream off. Oh my! Absolutely delicious!!! I used riced cauliflower with a little turmeric as a side - can’t miss with this recipe 😊
  36. Yvette
    This recipes is an absolute hit! I used unsweetened coconut cream, red curry paste and tilapia fish. It is incredibly easy to make.
  37. Julie
    Wow, we loved this recipe!! We served it over some steamed riced cauliflower and it was perfect. Thank you. A new weekly meal!
  38. Melissabee
    Delicious! We tried this dish with salmon and found the two distinct flavors of the fish and the sauce competed with each other, diminishing the flavor of each. We tired the recipe with a mild white fish and it was spectacular! This is definitely a dish on repeat in our house!
  39. Kathi Whitten
    We just fixed this for dinner--and BOY WAS IT DELICIOUS! I felt like I was in a restaurant having a fancy meal. Thank you. We will be fixing this often!
  40. Soph
    Easy and delicious! Added 2 crushed garlic cloves which worked perfectly.
  41. Kat Boman
    My husband and absolutely love this dish, the flavour is amazing. We had a few friends over served it with tumeric, cauliflower rice, what a hit, yay. Thank you.
