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!Kristyn
- 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!
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.
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!
