Easy Seafood Soup Recipe

When it comes to comfort food, a hearty soup or stew always does the trick. You just can’t beat a warm bowl of flavorful soup. We love this seafood stew, as well as my hearty vegetable soup, corn chowder and crockpot jambalaya.

Don’t you just love how easy and delicious slow cooker meals can be? They are great for busy weeknights and long weekends. This slow cooker seafood stew is a delicate, rich stew that is easy to prep and is a healthy dinner option.

The great thing about this slow cooker seafood stew recipe is that you can use fresh or frozen shellfish, just like in my recipe for shrimp scampi. That way no matter where you live you can enjoy a delicious seafood recipe. Also, I like to use fresh vegetables whenever I can and they are perfect in this slow cooker stew. Easy, healthy and super tasty!

  • Seafood: I recommended using any two pounds of seafood you would like for this seafood stew recipe. I used large deveined shrimpand large scallops You could also use lobster, crab, crawfish, mussels, clams or white fish like cod or halibut.
  • Broth and tomatoes: The base of this stew is made with a savory vegetable broth mixed with crushed tomatoes and tomato paste.
  • Vegetables: Diced yellow potatoes, a few cloves of minced garlic and chopped onion add aromatics and texture.
  • Seasonings: Lots of dried seasonings are the key for giving this seafood stew the perfect flavor! I like to use a mix of dried thyme, basil, oregano, celery salt, crushed red pepper flakes, cayenne and salt and pepper.
  • Fresh parsley: Right before serving, sprinkle some freshly chopped parsley on top for the perfect finishing touch!

Substitutions and Variations

As mentioned above, feel free to use your favorite type of fish when making this seafood soup. You can also add in other veggies such as carrots or peppers, or even mix in some fresh spinach or kale to wilt at the very end of cooking.

Make it a bit spicier with a little more red pepper flakes, cayenne, a dash of hot sauce or some cajun seasoning like my gumbo recipe. Or add in a bay leaf for more flavor or a squeeze of fresh lemon juice for a small punch of citrus for brightness.

5 star review

What a delicious way to use seafood!! It’s packed with so much flavor and the shrimp goes so well with the tomato flavor. Definitely making again!


Expert Tips

  • Shrimp shells. I leave the shells on the shrimp during the cooking process because that’s where a lot of the flavor comes from. Just make sure to remove the shells and tails before eating.
  • Broth. Using veggie broth will make the seafood flavor more subtle, however you can also use seafood stock for a bolder taste.
  • Low and slow. Although you can cook the stew on high heat in your crockpot, I recommend using the low setting if you have the time. The longer the soup simmers, the more flavor it will have. The fish will also stay super tender this way.
  • Serving suggestion. A side of Red Lobster cheddar biscuits goes perfect with this stew!

Recipe FAQs

Can you cook this on the stovetop?

Yes, you can make this seafood soup recipe on the stove. I like to sauté the onions and garlic in a little bit of olive oil or butter first and then add the remaining ingredients. Simmer for about 30 minutes.

What’s another word for seafood stew?

A few others names it goes by is fish soup, shellfish stew, Cioppino, bourride, brodetto, cacciucco, zarzuela and gumbo.

What goes well with seafood stew?

We love to serve this stew with a loaf of artisan bread, a French baguette or homemade dinner rolls. You can also serve the soup over cooked white rice to make it even heartier.

How long does fish stew keep in the fridge?

Although it does taste best the day of preparing, you can store leftovers in an airtight container in the refrigerator for up to 2 days. Just make sure not to overheat the stew when warming back up so the fish doesn’t get too chewy!

      I did not use the celery salt. Hubby doesn’t like celery. It was great without it!

    The idea of a tomato base with seafood didn’t seem too appealing to me at first but I didn’t have the ingredients on hand for chowder, so decided to give this recipe a try. I tweaked the spices a bit based on our preferences. Used haddock and scallops. SO GOOD! My husband loved it too!

    Excellent Stew!
    Made this yesterday. I didn’t have celery salt or fresh parsley, but the stew was amazing. I used 1 Lb of large, peeled, deveined shrimp with tail and 1 Lb bay scallops. Cooked on high 5 hours and seafood cooked in 30 minutes.
    All you need is French bread! Enjoy!

    Making this right now. I pretty much did every step!

    Added some hot sauce and mixed the broth with clam juice. Wife came home from work, and needless to say she was surprised and excited! Shoot I’m excited too.

    Wait till my mom tries this!

    TY for the recipe! Next time I’m throwing in shrimp in addition. I only used red snapper this time

    today i’m making it for the second time, the first time i loved it but it was a tad too spicy but still wonderful, i used zoup fish broth, shrimp, haddock and scallops. this time i’m using half vegetable broth and half seafood broth with semi cooked russet potatoes, since i started late, bigger shrimp, haddock and scallops, lots of onions and garlic, chili tomatoes instead of the cayenne pepper and pepper flakes.
    i love this recipe because i can change it depending on what’s on hand, in my house, that’s important. i will let you know, it smells wonderful. l love slow cooker recipes, please keep ’em coming.

    Can you freeze this stew? I made a large crockpot full of Tuna, Minced clams, Shrimp, and Crab meat and have lots left over (including the potatoes onions, and the rest of the ingredients. I can only keep so much in the fridge. Hopefully, I can freeze the remainder in containers. Thanks!

    I have to say that I was a naughty girl and I added cream cheese and milk. I subbed the potatoes for carrots and it took so long, over 3 hours on high in the Crock-Pot and carrots were still hard. So I switched it over to the Dutch oven on the stove. 40 minutes at a low boil later, carrots were finally softer so I added the seafood, cream cheese and milk. Delicious! Garnished with parmesan.

    I’m going to make this today, but I have a question. My store was out of vegetable broth/stock so I decided to try using Clam Broth. Should I use just 2 cups instead of 4 so the taste isn’t overpowering?

    • Reply
      • Jamielyn Nye

      I never tried but you could try 2 cups and mix in 2 cups water.

    This is absolutely delicious! We used scallops and a fish medley from our local co-op (halibut, salmon and tuna steak pieces). We dropped the broth to 3 cups and also sauteed the onion plus added red peppers and grated carrots before putting the other ingredients in the crock pot. Loved it and will be adding this to our recipe rotation!

    This is an amazing stew! I subbed carrots for potatoes and had to use parsley flakes for oregano. It’s a delicious broth with the right spices. I used salmon, cod and halibut because that’s what I had in the freezer.
