Salmon Soup (or Lohikeitto)
This Salmon Soup is creamy, hearty and one of the best dishes you can have during a cold winter night. The salmon chowder turned out amazing on my first try. I mean, you can’t really go wrong with flaky salmon, cream, bacon, sweet peas, and corn.
The flavors are so fresh, and I added some lemongrass and also lemon juice for a citrusy finish. As a result, the soup feels light and a tad citrusy. Also, I want to mention that this creamy salmon soup it’s not labor-intensive.
It involves a few steps to follow, but nothing crazy, so you can totally go ahead and make this on a weeknight. In addition, this is also a great way to use any leftover roasted salmon or skin. I only used one cup of cream, to make it on the healthier side.
Then I added potatoes, which I blended after they were fully cooked. This is a great trick to make a very creamy and dense soup while still keeping it healthy. The sweet peas and corn add such a nice flavor, and their sweet and summery taste brightens up the soup.
They add a nice pop of color and some fun texture. The creamy fish soup is topped with crumbled bacon for a savory, salty finish. The flaky roasted salmon, the creamy broth, and the subtle lemon undertones, all work so nicely together to create a comforting yet beautiful meal.
Here is what you will need:
- Salmon: I love using salmon filet without the skin here as it has a nice texture. You could also use the skin-on salmon but I found out that when you boil the fish, the skip tends to come soggy and robbery. Hence, I usually omit it. However, you can use salmon skin or the salmon carcass.
- Onion and garlic cloves: This adds plenty of flavors, so do not skip them!
- Olive oil: To sautee the veggies.
- Vegetables: Potatoes, bell peppers, sweet peas, sweet corn.
- Seasoning: Fresh thyme, salt, and black pepper.
- Lemongrass paste and lemon: It adds a nice citrusy finish to the whole dish. However, feel free to skip it.
- Broth or stock: I use vegetable broth here as I want the broth to absorb as much of the fish as possible. But, chicken broth or fish broth will work as well.
- Heavy cream: This makes the soup extra rich and creamy.
- Bacon and fresh dish: To garnish.

Variations and substitutions:

How do you know when salmon is done?
In general, fish like salmon requires little cooking time. It is important NOT TO OVERCOOK the fish because the dish will turn out mush.
Since salmon is cooked easily, it is important to keep an eye on it as it cooks. It generally needs about 5-7 minutes of cooking.
You know it is ready when the flesh turns opaque and it flakes easily with a fork. Also, use a meat thermometer to check for doneness. According to the USDA, it needs to have an internal temperature of 145 degrees F.
Just remember that the fish will continue to cook off heat as it sits in the broth. So, it is best to cook it to about 135 degrees F, as the temperature will increase as it sits.

How to store leftovers?
First, let leftover cool at room temperature. Then, transfer leftover soup to an airtight container and refrigerate for up to 3 days.
Reheat it in a microwave or a pot over low heat, until fully warm.
Can you freeze salmon soup?
Yes. I recommend using quart bags for this soup. First, use a cup to transfer the soup from the pot into the bag.
Then, squeeze out excess air and seal the bags. The bags can nicely be stored in the freezer for up to 2-3 months.
Also, when reheating, you may need to add a bit of heavy cream, add ¼ cup at a time. Preferably heat it on the stovetop if you will be adding more heavy cream.
- I love using boneless skinless salmon filets here. However, you could use the skin-on or even different fish types.
- Also, feel free to add other veggies to it. Such as green peas, broccoli, etc.
- To make it extra creamy, you can use a food processor or immersion blender and blend about half of the soup with potatoes together.
- I added some crispy bacon on top. But this is optional.
- In addition, for a more festive look, serve this creamy fish soup in individual bread bowls and garnish it with chopped dill.
