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.
Recipe FAQs
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.
A few others names it goes by is fish soup, shellfish stew, Cioppino, bourride, brodetto, cacciucco, zarzuela and gumbo.
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.
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!
Love seafood? You’ll also love my sheet pan salmon, shrimp skewers and lemon baked fish. My ceviche also makes a great appetizer!

What a delicious way to use seafood!! It’s packed with so much flavor & the shrimp (what we use) goes so well with the tomato flavor. Definitely making again!
So glad you liked the combination of flavors, Kristyn. Thanks for sharing.
This is such a great addition to our weeknight favorites! My family loved it! I will definitely make it again soon! Thanks!
Thanks for sharing, Toni. I am glad your family enjoyed it!
This is my new favorite seafood stew recipe! Turned out really delicious and super tasty! Perfect for any gatherings! Will surely have this again! Thanks a bunch for sharing!
Thanks for trying something new, Allyssa. Glad you found a keeper!
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.
Your substitutes sound delicious! So glad you enjoyed the soup :)
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?
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!
That sounds delicious! Glad you were able to make substitutions that work for you :)
May I ask what size you cut the fish pieces?
