“Sancocho” de Mariscos (Shellfish Stew)

Sancocho de mariscos (seafood stew)

Did you know that some of the recipes I post have been weeks or even months in the making? This is one of them.

Sometimes I go through periods where I would cook up a storm, and create and test several recipes at the same time. They sit there until I have the time to post them, or as backup content in case I run into any problem and cannot work for a while.

Sancocho de mariscos (seafood stew)

I gotta be honest with you, this is a recipe inspired by one of my favorite soups in one of my favorite restaurants, I always order it when I go there, and decided I wanted to create my homemade version.

But why “sancocho“?

Sancocho de mariscos (seafood stew)

Well, here’s another confession: this soup has a lot of in common with our beloved meaty stew, most notably the some of the roots and plantain, but there’s also a lot difference when it comes to taste, and cooking method. Please don’t hold that against me.

Anyway, I am sure you won’t once you try it.

This is the perfect time of the year for soups, especially the long-cooking ones. I seriously recommend this “sancocho” de mariscos (shellfish stew) loaded with the flavors of the sea, thick and hearty.

And whatever ails you these days, this is the soup to warm your bones or lift your spirits. Heaven knows we all need that sometimes.

Buen provecho,

I seriously recommend this “sancocho” de mariscos (shellfish stew), thick and hearty and loaded with the flavors of the sea.
Serves: 6 servings
  • 3 lb of large whole shrimp
  • 2 unripe plantains, peeled and sliced
  • 1.5 lb of auyama (West Indies pumpkin), peeled and cubed
  • 1 teaspoon of dry oregano
  • 4 sprigs of thyme
  • 4 cloves of garlic, crushed
  • 1 lb of waxy potatoes, peeled and cubed
  • 2 lb of assorted shellfish and seafood (see notes)

  1. Shell the shrimp and separate shells/heads from the rest. Return shrimp tails to the refrigerator.
  2. Boil the shells and heads over low heat in 2 quarts [2 lt] of water for 45 mins, frequently replenishing the water to maintain the same level.
  3. Sieve to separate the liquid from the solids. Throw away the solids.
  4. Return the broth to the heat, add oregano, thyme and garlic.
  5. Add the plantains and half the pumpkin to the liquid and boil until everything is cooked through. Add water as it becomes necessary to maintain the same level.
  6. Remove from the heat and cool to room temperature.
  7. Remove the thyme and blend until all the solids have dissolved.
  8. Return to the heat and add the potatoes and remaining pumpkin, simmering over low heat until the solids are cooked through.
  9. Add the shellfish and shrimp tails. Simmer until the shrimp turns bright pink.
  10. Stir in cilantro and lime juice, season with salt and pepper to taste.
Pick whatever shellfish and seafood you like, mine included mussels, lobster and scallops. You may also add bits of fish of your choice.

    Hello! I love your website…so pretty! Thank so much for this recipe! I’ve been a pescetarian for a very long time and so miss the taste of sancocho. I had some fish sancocho while in DR this year and it was awesome. I tried it today with your recipe except I added tilapia, sofrito, and omitted the thyme. It was so good!!! Topped it off with hot sauce and some white rice..thanks so much for this!

    This soup sounds really amazing! I love seafood, and soup is great to include all different kinds of seafood in it. The stock is wonderful, yet very simple to make. And me too, it takes weeks and months sometimes before I publish a post/recipe after testing. I take way too long to create one post… I sometimes wonder how bloggers can post everyday! I love your photography work in this post, by the way. The soup looks very very tempting!

    This soup looks amazing. Your photos are always so darn gorgeous!

    I have yet to post a caldo de mariscos and your recipe and photos have inspired me. Although I’m thinking your seafood is way yummier than the seafood we have in Colorado. LOL!

    I hope your version was even better than the one you had in the restaurant. It looks delicious! After my last summer vacation I fell in love with every kind of carribean and carribean inspired kitchen. Your posts make me mouthwater! :-)
