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.

Ingredients
Just basic low carb ingredients and fish make this tasty keto fish pie.
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:
- Topping – Cooking the cauliflower first means it can be cooking on the stove whilst you get on with the sauce.
- Sauce – The cheese sauce is easy to make and can be set aside until ready for use.
- Fish -I find that steaming the fish is a great way to maintain the flavours. You could bake or grill the fish too. We use prawns which some people also call shrimps.
Cook and mash the cauliflower with the cheese and herbs.
Place the cooked fish and prawns in a baking dish.
Spoon the cauliflower mash on top of the fish.
Bake for 20 minutes.
Baking Tips
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.
Variations
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).
Storage
Keep any leftovers in the fridge in a sealed container and it should last up to 3 days. Reheat in the oven or microwave.
What to serve with keto 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.

For a less watery/ soupy cauli mash…do not boil the cauliflower simply break into florets and place them in a microwave safe dish
(Corning ware)
And microwave on high until really, really tender. Begin with 6 minutes and then poke the cauliflower with a fork and test for tenderness.
By not boiling the veg…it will be drier and easier to “mash” without much draining. Only natural moisture within the cauliflower will be released into the bottom of the microwave dish. Drain it away.
Also, “mashing” by whizzing the florets in a food processor, which is so much easier…and just season with desired spices and only use butter!
Plus…if you want to remove the cabbage flavour that lingers in the mash…simply add a very tiny fresh clove of garlic!
It neutralizes that cabbage taste greatly!
Once the food processor produces a very smooth cauliflower mash…proceed with the remainder of the recipe! Enjoy!
P.S. what white fish did you use, please? I know so little about fish.Reply
Angela Coleby
I used cod for the white fish.

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?
ThanksReply

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

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.
