Hearty and delicious, this easy Creamy Fish Soup is made in the slow cooker. All you need is a simple side of homemade bread or drop biscuits and you have the best comfort food ever.
This recipe for fish chowder combines potatoes, fish (you can swap in whatever kind you like), corn, and broth, topped with crispy bacon bits. Perfect for warming up on cold winter days.

Creamy fish and potato soup is an easy to make cozy meal. Comfort food in a bowl that is ideal for busy weeknights.
I happen to think the slow cooker is the best kitchen invention ever. Set it and forget it cooking. While dinner cooks I can do other things. The food always turns out delicious.
Slow-cooker soup is so easy to make. I love to make a huge batch. Great for more meals during the week. It’s perfect for putting in the freezer too.
- Slow Cooker Pho is a great cheat version of the classic Vietnamese dish.

Best Fish For Making Soup
This is where you can experiment and see what works best for you and your family. You have lots of choices, and each will produce delicious soup. You can use fresh, or frozen fish, and even canned varieties as well.
In this recipe I used pre-cooked imitation crab. Works like a charm and is budget-friendly too. I always have this in the freezer. Perfect for salads, sandwiches, pasta, and roasted tomato crab soup.
Since fish cooks quickly, it is added to the slow cooker near the end of the cooking time. This is basically a creamy potato soup recipe with fish. You could try:
- tuna
- salmon
- haddock
- cod
- shrimp
- whitefish

Substitutions/Recipe Tips
Fish Soup Seasonings: You can use a variety of seasonings. For this recipe, a Cajun seasoning blend. Smoked paprika and Old Bay Seasoning are great choices too.
Broth Choices: If you are looking for a vegetarian version of this fish soup recipe, replace the chicken broth with vegetable broth.
Frozen Corn: I always have this on hand. You can replace it with canned corn as well.
Cream Substitutes: In most of my recipes, I use evaporated milk. I find it convenient (it doesn’t curdle) and something I always have on hand. Great for both savoury and sweet recipes. You can also use cream, milk, or non-dairy options like coconut milk if you wish.
Can You Freeze Fish Chowder Soup? Yes, you can. It will last 3-4 days in the fridge. To freeze it, place in an airtight container or freezer bag. It will last for several months.
Reheat thick soups containing milk or cream over low heat, stirring frequently.
Is Chowder Soup?
Always a fun topic and debate. Chowder is a thicker kind of soup generally cream-based. Soup is usually thinner and is broth-based. That is not to say soup cannot be thick and contain cream. My mushroom soup is not chowder, but is thick and does contain cream (and cream cheese).
- Basic Chowder usually combines stock, potatoes, fish or shellfish, salt pork and milk.
- New England Chowder containes clams and cream, along with potatoes and bacon.
- Manhattan Chowder is tomoato based instead of cream based, and has a nice red colour.
- Long Island Chowder uses both cream and tomatoes in the base.

Gloria Duggan | Homemade & Yummy
I do not see why that would not work. I would give it a try for sure. ENJOY!
Tracy

I had the best fish soup of my life while travelling in Norway years ago, and have been trying to re-create it ever since. Definitely a big bowl of comfort, and something my kids are always super excited to eat. Love that this one is made in the slow cooker and the tips for preventing curdling after thawing, perfect!
Gloria | Homemade & Yummy
You are welcome. Hope you give this recipe a try.
Trish Bozeman
YUM! Like a super flavorful chowder. Love the cajun seasoning with the crab. Such a great recipe, Gloria!
Gloria | Homemade & Yummy
Thanks so much. It is a favourtie around here.
Lisa Lotts
Your recipe reminds me of my grandmother’s chowder recipe, but yours looks even thicker than hers. Such a classic, hearty soup — and absolutely ideal for this time of year. Do you think clam broth would work instead of chicken broth? I happen to have some in the pantry, but I’m out of chicken stock. LOL!
Gloria | Homemade & Yummy
I think it would work just fine. Enjoy and let me know how it turned out.
Veena Azmanov
