Arroz de Marisco

Arroz de Marisco is a Portuguese seafood rice cooked loose and soupy in a tomato and shellfish broth, loaded with shrimp, clams, mussels, and sometimes crab, and finished with fresh cilantro. You make it by building a tomato based sofrito, adding rice and shellfish stock, and layering in the seafood at staggered times so nothing overcooks by the time the rice is done.

The dish is a coastal specialty found up and down Portugal's Atlantic coast, especially around Peniche and the Algarve, where the seafood comes straight off the boats each morning. Unlike a Spanish paella, Arroz de Marisco is meant to be wet and brothy, almost like a thick seafood soup with rice suspended in it, not a dry, separated grain dish.

Getting the texture right depends entirely on when you add each type of seafood, since shrimp, clams, and mussels all cook at different speeds and none of them forgive being overcooked.

What Actually Matters

Stagger the seafood additions by cook time. Clams and mussels go in early enough to open and release their liquor into the broth, shrimp go in with just a few minutes left so they stay tender, and anything precooked, like crab, goes in at the very end just to warm through. Dumping all the seafood in at once is the most common mistake, and it leaves you with rubbery shrimp by the time the slower shellfish finally opens.

Arroz de Marisco Recipe

Serves 4. Prep time: 20 minutes. Cook time: 35 minutes. Total time: 55 minutes.

Ingredients

• 3 tablespoons olive oil
• 1 medium onion, finely chopped
• 4 cloves garlic, minced
• 1 red bell pepper, finely chopped
• 1 tablespoon tomato paste
• 1 (14 ounce) can crushed tomatoes
• 1 cup dry white wine
• 4 cups shellfish or fish stock
• 1 cup short grain rice, such as carnaroli or arborio
• 1 pound littleneck clams, scrubbed
• 1 pound mussels, scrubbed and debearded
• 1 pound large shrimp, peeled and deveined
• 1 bay leaf
• 1/4 cup chopped fresh cilantro
• Salt and black pepper, to taste

Method

1. Heat the olive oil in a large, wide pot over medium heat. Add the onion, garlic, and bell pepper, and cook until softened, about 6 minutes.
2. Stir in the tomato paste and cook 1 minute, then add the crushed tomatoes and cook 5 minutes until slightly thickened.
3. Pour in the white wine and simmer 2 minutes to cook off the alcohol.
4. Add the shellfish stock and bay leaf and bring to a boil.
5. Stir in the rice, reduce to a steady simmer, and cook uncovered for 12 minutes, stirring occasionally.
6. Add the clams and mussels, cover, and cook 5 to 6 minutes until the shells begin to open.
7. Add the shrimp and cook, uncovered, for 2 to 3 minutes more until the shrimp are pink and just cooked through and the rice is tender but still loose and soupy.
8. Discard any shellfish that haven't opened, along with the bay leaf.
9. Season with salt and pepper, stir in the cilantro, and serve immediately in wide bowls.

Tips, Variations, and Storage

Add cooked crab or lobster claws in the last minute of cooking if you want to build the dish out further, since they only need to warm through. This dish is best eaten fresh, as the rice keeps absorbing liquid and turns thick and gluey on standing or reheating. If you must store leftovers, add a splash of stock when reheating to loosen it back up. Discard any clams or mussels that stay closed after cooking.

Frequently Asked Questions

Why is my Arroz de Marisco too dry?

This dish should be loose and brothy, almost soup like, unlike a drier rice dish. If yours turns dry, add more hot stock as it cooks and pull it off the heat while it's still a little soupier than you expect, since the rice keeps absorbing liquid off the heat.

Can I use frozen seafood?

Yes, just thaw it fully first and pat it dry so it doesn't dilute the broth with excess water.

What rice should I use?

A short grain rice like carnaroli or arborio holds up well and releases a little starch for body. Avoid long grain rice, which won't give the right texture.

How do I know if a mussel or clam is bad before cooking?

Discard any that are cracked or that stay open and don't close when tapped before cooking, and discard any that remain closed after cooking.

Can I make this less spicy or add heat?

The base recipe isn't spicy. A dash of piri piri sauce at the table is a common way Portuguese cooks add heat without changing the pot itself.
