Seafood Stew 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 Mexican chicken soup.

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 frozen shellfish and just thaw it out. 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.

Type of seafood to use

For my seafood stew recipe, I am using large deveined shrimp and large scallops. 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.

You could add lobster and crab if you desire. I recommended using any two pounds of seafood you would like for this stew.

The great thing about stew recipes is that you can modify the ingredients to you likes and needs. This recipe is hearty and healthy with all the great fresh vegetables and seafood. A good loaf of crusty french bread is what you need for soaking up all that amazing broth.

How to Make Seafood Stew

  1. Add tomatoes, broth and spices to slow cooker. Add all the ingredients (minus the fish) in the bottom of your crockpot.
  2. Cook the soup. Cover with lid and cook until the potatoes are fork tender, about 2-3 hours on high or 4-6 hours on low.
  3. Add seafood. Mix in the thawed seafood and cook on high for an additional 30-60 minutes, or until the fish is fully cooked.
  4. Serve and enjoy! Add fresh parsley on top if desired and serve with hot french bread!
