Fish Pie with Mashed Potato Topping

Fish pie with mashed potato topping, an all-time favourite classic dish that brings all the family together around the table.

There are dishes that are perfect for the cold season, like stews or hot soups, they are soothing and ideal when you need a bit of comfort. Other dishes are so refreshing, and are best during the hot summer days to cool us down.

And there is yet another category of dishes that are perfect all year round. And this lovely fish pie with mashed potato topping is definitely one of those foods that, no matter what time or day, will always be the first choice when it comes about cooking the perfect family meal.

What is so great about it is that everybody can tuck into it, there is no strong flavour or spiciness to keep little ones away. But it is so delicious, you will find yourself making it again the very next day.

I have used cod for my fish pie, but salmon is another great option, and many people use it to make this kind of fish pie. Haddock, or smocked haddock, is also a nice choice, so just use your favourite fish and enjoy a great meal. Yum!

I always try to cook fish as often as I can, it’s the perfect choice for a healthy lifestyle, it’s got the right kind of fat that the body needs, and it’s so delicious. I know that people can be put off my some fish that has a stronger, “fishy” taste, but cooked in a pie, it’s just perfect.

Pies, I absolutely love them. They are great if you have leftovers, just throw any veggie and meat in, and you are good to go. My Leftover Turkey pot pie is a big hit with us, and I cook it often. After all, pies are meant to comfort, and they so do it!

    This looks delicious, Daniela. I like fish pie with any white fish. Although I love salmon, I’ve never tried it in fish pie, but I think it should be just as nice.
