When I got my Instant Pot at the end of last year, it took me weeks, if not months, to actually like the appliance. There were too many things that bothered me about it. I even wrote an article about 7 Things You Need To Know About Instant Pot.
After I figured out how to make Instant Pot No Knead Dinner Rolls, I became a convert and a big fan of Instant Pot. One of the things I absolutely adore about it is the beautiful and clear broth that you get when making soup.
This Instant Pot Fish Soup has been my go to dish for the past couple of months. It’s delicious, it’s healthy, it’s easy. And it’s also beautiful with it’s clear golden broth and blush pink salmon.
Also, funny enough, my toddler absolutely adores this Fish and Potato Soup.
The flavour of this Fish Soup is very light, yet it’s very filling. It’s a perfect dish to make in an Electric Pressure Cooker in the hot summer months when you don’t want to spend time cooking on the stove. And it’s also amazing in the cooler fall and winter months when you crave a delicious and satisfying hot soup.
This Instant Pot Fish Soup is also very similar to my childhood favourite, Affordable Canned Salmon Soup.
What are the ingredients for the Instant Pot Fish Soup
The ingredients aren’t anything fancy and you only need a few of them:
- onion
- carrot
- salmon
- potatoes
- dill
- broth
- seasonings
Do you use frozen salmon or fresh salmon for this Fish Soup?
Here’s the beauty of this soup: you can use either fresh or frozen salmon. Moreover, you don’t even need to defrost the salmon if you don’t have time!
In fact, I would suggest not to use fresh salmon for this Instant Pot Fish Soup and stick with a good quality, sustainable frozen salmon instead. It will make the soup much more budget-friendly and affordable.
I’ve made this Fish Soup with fully defrosted salmon, fully frozen salmon, and with semi-thawed salmon. The taste is the same!
TIP: Get a package of frozen and sustainable salmon filets when it’s on sale and keep in your freezer for a quick, delicious, and affordable dinner!
How to make Instant Pot Fish Soup
Just as most of my Instant Pot Recipes go, this one is pretty easy:
- Sauté a bit of onion and carrots until nice and soft in electric pressure cooker
- Add the seasonings, potatoes, fish, broth, and cook in Instant Pot
- Stir in some fresh dill once done and serve!
Easy-peasy!
How long to cook Instant Pot Fish Soup?
It took me a few tries to come up with the proper measurements and timings but I finally have it figured out. Well. Almost.
I cook this Fish Soup for 3 minutes on high pressure in my Electric Pressure Cooker. But I have a sneaking suspicion that it would work even if cooked for 2 minutes.
Yet, I am afraid to try. Salmon will be cooked in 2 minutes but I am not sure about the potatoes. I think they will. Yes? Maybe?
Request: if anyone tries to make this Salmon and Potato Soup in their Instant Pot in 2 minutes, please let me know!
How long does it take to make Instant Pot Fish Soup?
Does this Fish and Potato Soup actually take 3 minutes to cook? NO WAY!
A lot of Instant Pot recipes online are trying to lure readers with such headlines as “5-minute mac and cheese” or “3-minute dinner” but it’s false advertising. Most of those recipes either don’t mention the time it takes for the electric pressure cooker to come to pressure or talk about it in passing.
In my recipes I always say how long it takes for my Instant Pot to come to pressure and to release the pressure. I also add the actual cooking time of the dish.
It takes about 10 minutes to properly sauté the onions and carrots. My Instant Pot takes about 23-25 minutes to come to pressure for this Fish and Potato Soup. And it also takes about 4 minutes to release the pressure.
Add the 3 minutes cooking time and another 10 minutes of prep and you get about 50-55 minutes start to finish. However, there’s only prep time and sautéing that are hands-on.
TIP: If you are worried that your Instant Pot silicone ring will smell like fish, just purchase an extra set of rings and use them specifically for seafood dishes.
Why are the carrots grated?
Many western dishes start with mirepoix, which often includes diced carrots, onions, and celery. Grating carrots is a very Russian thing to do.
When carrots are grated instead of diced, they get softened very quickly and then they almost melt into the soup while providing it with tons of flavour and beautiful colour.
There are tons of cooking videos online now where onions and carrots are chopped into big pieces and then barely cooked at all before the rest of the ingredients are added. No wonder why there are so many parents complaining that kids don’t like when onions or carrots are added to the recipes.
With the surge of everyone creating cooking videos and a decline of people watching real cooking shows with real and trained chefs, many people don’t know how to properly dice the vegetables and cook them for the soups or sauces.
The trend in quick recipes is also to blame!
Properly cooking carrots and onions as the beginning of a sauce or a soup is important. The vegetables need to soften and release their sugars, which then will start slightly caramelizing and imparting a lot of flavour.
Grated carrots and finely diced onions, once cooked this way, melt into the broth in a way that the texture of the Fish Soup isn’t impacted.
But what if I want to turn this Instant Pot Fish Soup into “dump and start” recipe?
Ok, even though I strongly (very strongly) encourage you to properly cook the carrots and onions first, it is not necessary. You could just add all the ingredients together and cook without sautéing, thus turning this Fish and Potato Soup into a perfect “dump and start” recipe.
Ingredients and substitutions for the Fish and Potato Soup
- Salmon
- I have tried making this Instant Pot Fish Soup with half Salmon and half Cod. Although the soup tasted great, the cod didn’t hold shape and got integrated into the broth. I love the beautiful golden broth in this soup so I prefer to use Salmon only. You can use salmon and cod together if you’d like.
- Potatoes
- I love using mini potatoes for this Fish and Potatoes Soup. In most stores they are sold in bags of 1.5 pounds, so I don’t have to weigh and measure. I just know that I need one bag of mini potatoes.
- I have made this soup with yellow mini potatoes and red mini potatoes. I prefer the flavour and texture of yellow mini potatoes, but red mini potatoes also work.
- You could use regular potatoes as well, just dice them into small pieces. Do not use Russet potatoes, as those would not work for the soup.
- Broth
- I always use Better Than Bouillon for broth. I have made this soup with both Vegetarian Better Than Bouillon and Chicken Better Than Bouillon. I honestly did not notice any difference in flavour.
- I am trying to find a Fish Better Than Bouillon in a local store as I think that would be totally amazing with this soup.
- Seasonings
- I really like Old Bay Seasoning for this soup and dry dill. You can use other seasonings if you’d like and experiment with different flavours like maybe Cajun spice or Provencal herbs.
- I don’t use a lot of salt in my cooking and for my taste the amount of salt in Old Bay, broth, and extra that I added is more than enough. If you prefer saltier food, just add more salt.
- Dill
- In my mind, dill and fish are a match made in heaven. So, I almost always have dill when cooking fish.
- You could use parsley instead or omit all the fresh herbs altogether, although I think they add a lot of flavour and complexity to the dish.

This Instant Pot Fish Soup is quick and easy. It's flavourful, filling, yet light. Great for summer or winter weather. Easy to make and delicious to eat. Let your electric pressure cooker do all the work!
- 1 tablespoon vegetable oil
- 1 large onion
- 1 large carrot
- 1 teaspoon dry dill
- 1 teaspoon old bay seasoning
- 1/2 teaspoon salt (or to taste)
- 1/4 teaspoon pepper
- 3 bay leaves
- 1.5 pound frozen skinless salmon filets
- 1.5 pound mini potatoes
- 6 cups vegetable broth
- 1/2 cup chopped fresh dill
Very finely dice the onion.
Grate the carrot.
If the salmon filets are defrosted or semi-thawed, cut the fish into 1 inch cubes. If the salmon filets are frozen, keep them whole.
Halve or quarter mini potatoes.
Press sauté button on your Instant Pot and add a tablespoon of vegetable oil.
Once the oil is hot, add the prepared onion and carrot.
Sauté for about 10 minutes stirring every once in a while to make sure the vegetables do not burn. The onions and carrots should become very soft and reduce in size by at least half.
TIP: If the onion and carrots begin to burn, add a splash of broth.
Once the onions and carrots are cooked, add a little bit of broth to deglaze and scrape really well to make sure that the bottom of the Instant Pot insert is clean. This will prevent the dreaded burn notice.
Add the seasonings.
Add the potatoes, salmon, and the rest of the broth.
Turn the sauté button off.
Put the lid on and turn the vent into the sealing position.
Press Manual or Pressure Cooker button (depending on your model) and using the arrow buttons set the cook time to 3 minutes. Depending on the temperature of the ingredients, it could take up to 25 minutes to come to pressure!!!
Once the Instant Pot beeps that the 3 minutes of cooking are done, do a quick release. Quick release will take about 4 minutes.
Open the lid, add the chopped fresh dill and mix.
Serve with extra sprinkling of fresh dill and a squeeze of lemon juice if desired.

If you are using frozen salmon filets, there's no need to defrost them or cube them. Feel free to add the whole filets and just break them up with a spoon once cooked.

Like you, I didn’t use my Instant Pot for a while after I bought it, but once I did, I haven’t stopped. I only use fresh ingredients except for the broth as I don’t always have homemade vegetable stock on hand,
I haven’t made fish soup yet and your recipe sounds so good! Thanks for sharing your recipe.

Yes, Instant Pot is a funny appliance. You really need to get to know it before liking it. This soup is amazing, it’s really delicious, and comforting, and easy!
