Smoked Mackerel Fishcakes
I'm very fond of fishcakes, but I'm not too keen on lots of mashed potato in them, which can be a bit heavy with oily fish. So I prefer to use other vegetables such as butternut squash in these Smoked Mackerel Fishcakes. The squash balances out the rich smoked mackerel to make a light meal.
Cooking butternut squash
You can cook the squash in a couple of different ways:
- Steam the squash. You need to cut the hard skin off the squash, remove the seeds, and chop the flesh into cubes. Then steam for about 15 minutes.
The downside is that the skin is very tough so it's time-consuming to remove, plus it takes a lot of effort - Bake the squash. This is my preferred method. You cut the squash into quarters lengthwise and remove the seeds. Then put the pieces face-down on a baking sheet and cook at 160°C fan, gas mark 4 for about 45 minutes. When you can handle the squash, scoop the flesh out with a spoon.
This method probably doesn't take much longer overall, and it's easier on the hands.
Prepare ahead:
Any meal that you can prepare ahead of time is invaluable when you're coming home from work to make a meal for the family. In this case, you can make the fishcakes and put them in the fridge, ready to cook, the night before. Just heat the oil and cook in 10-12 minutes. Then all you need is salad or some frozen veg to make a delicious meal.

Hi Anne,
Yes, you can freeze them. I regularly do 🙂
Frozen squash is ok. Baking them will get rid of any excess moisture.
Mackerel in oil, well-drained, should be ok. I don't see why the tomato sauce ones wouldn't work. Do let me know if you try it.

Good morning from a fellow mackerel lover,
I have a couple of queries:
1. As the only mackerel lover in the house, can I make these and freeze them to cook later? When making a full batch? I usually half or quarter recipes.
2. I have butternut squash cubes in the freezer. Can I use these? I am aware using frozen veg would prevent me from freezing uncooked fishcakes.
3.I also have tins of mackerel in oil and tomato sauce in the cupboard. Are these suitable for making fishcakes?
King regards
Anne
