    This keto fish pie is an easy dinner recipe and pure comfort food. White fish, salmon and prawns are served in a creamy cheese sauce and topped with a cheesy cauliflower mash.

    Fish pie is a classic British recipe and use mashed potato for the topping. To make this a low carb fish recipe, the versatile cauliflower is used instead. The creamy sauce uses cream cheese for a low carb option too.

    The Chief Taster loved this keto fish pie so much on the first bake that despite declaring he was full, he dived in for a second helping. Which led to further declarations of a full stomach. The dish went immediately on the repeat request menu and leftovers (the small amount that was not devoured in the first serving) were enjoyed for lunch the next day.

    How to make a keto fish pie

    I find the best way to make this fish pie is to be organized and cook the 3 main components in this order:

    1. Topping – Cooking the cauliflower first means it can be cooking on the stove whilst you get on with the sauce.
    2. Sauce – The cheese sauce is easy to make and can be set aside until ready for use.
    3. Fish - I find that steaming the fish is a great way to maintain the flavours.   You could bake or grill the fish too.

    Although I have made this fish pie in a large baking dish, I’ve also made it in large ramekin pots for individual pies too. The pie can be assembled and kept aside in the fridge until you are ready to bake.

    Recipe ingredient suggestions

    You could play around with the ingredients to the fish pie and give it your own twist. A few suggestions are:

    • Smoked fish
    • Lobster (that’s a payday pie!)
    • Spinach, cooked
    • Mushrooms, sliced and cooked
    • White wine in the sauce
    • Smoked cheese (Gouda would be great)
    • Hard boiled eggs (the traditional fish pie can be served with hard boiled eggs in it).

    What to serve with fish pie

    Green vegetable or a green salad make a great side dish. Roasted low carb alternatives to potatoes are also a delicious side dish. Try cheesy green beans, roasted asparagus, turnip fries, cheesy baked asparagus or roasted broccoli.

      This is really lovely. We will definitely have this again. It would be really useful though if you give the ingredients in grams and millilitres as well as outside US nobody uses cups. It would save a lot of faff for everyone else outside America that uses your recipes. Thanks.

      This is so good. I did leave out the cream and did Soeur cream and cream cheese for the sauce and just cauliflower and butter with S&P for the topping with grated Parmesan on top. And used flaked smoke fish with scallops. I’m in heaven, low carb, lemony, creamy, mashy heaven 😍

      Thanks so much. We LOVED it. We have some left over. Is it OK to pop in the fridge and have again tomorrow? If so, how would you recommend heating?
      Thanks

        Leftovers store fine in the fridge and can be reheated the next day either in the oven or microwave. Glad you enjoyed it!

      Absolutely delicious! I added a couple of hard boiled eggs in with the fish. Was demolished by everyone, including my 3 and 6 year old

      thank you so much Angela for a great keto version of our favourite British grub! Perfectly creamy and thick with no flour or other high carb thickeners. The non low carbers in your family will LOVE it too. A great family feed. xxx

          I just made this meal for the family and I followed your instructions all the way but I haven't eaten yet cause I'm confused about the portion size and the carb count you have 3.5 is that minus the fiber 1.2 already or do I minus the fiber 1.2 myself and the net carbs is 2.3?

            The recipe card shows the total carbs and fiber so you subtract them yourself.
