Portuguese Monkfish Rice: A One-Pot Seafood Recipe

Portuguese monkfish rice, or arroz de tamboril, is a tomato-rich seafood dish made with firm monkfish, rice, aromatics, and broth. It is often served loose and spoonable rather than fluffy, making it a comforting one-pot meal; the exact seasonings and consistency vary between regions and households.

Ingredients

1½ lb monkfish fillets, skin and membrane removed, cut into 1-inch pieces (680 g)
1½ cups short- or medium-grain rice, such as Portuguese carolino (300 g)
5 cups seafood stock or fish broth (1.2 L), plus a little extra hot broth or water if needed
3 tbsp olive oil (45 ml)
1 medium yellow onion, finely chopped (about 1 cup or 150 g)
1 medium red bell pepper, finely diced (about 1 cup or 150 g)
4 garlic cloves, finely chopped (about 12 g)
2 cups chopped ripe tomatoes, or canned chopped tomatoes with their juices (300 g)
1 tbsp tomato paste (16 g)
½ cup dry white wine (120 ml)
1 bay leaf
1 tsp sweet paprika (2 g)
¾ tsp fine salt (4 g), plus more to taste
¼ tsp freshly ground black pepper (about 0.5 g)
Small pinch red pepper flakes, optional (about 0.2 g)
½ cup chopped fresh cilantro, plus extra to serve (about 15 g)
1 tbsp lemon juice (15 ml), plus lemon wedges for serving

Instructions

Prepare the ingredients. Pat the monkfish dry and cut it into evenly sized pieces so it cooks at a similar rate. Check carefully for any remaining membrane or tough connective tissue and trim it away. Chop the onion, pepper, garlic, tomatoes, and cilantro. Measure the rice and seasonings, and warm the seafood stock in a small saucepan or microwave until hot but not boiling. Keeping the broth hot helps the pot return to a simmer quickly when you add it.
Soften the aromatics, 8 minutes. Heat the olive oil in a wide, heavy pot or Dutch oven over medium heat. Add the onion and bell pepper with a small pinch of the measured salt. Cook for about 6 minutes, stirring occasionally, until softened but not browned. Add the garlic, bay leaf, paprika, black pepper, and optional pepper flakes. Stir for about 2 minutes, just until fragrant; lower the heat if the garlic starts to color.
Build the tomato base, 5 minutes. Stir in the tomato paste and cook for 30 seconds, then add the chopped tomatoes. Simmer for about 4½ minutes, stirring now and then, until the tomatoes begin to break down and the mixture looks saucy. Pour in the white wine and simmer for 2 minutes, scraping the bottom of the pot. The wine should lose its sharp raw smell, though it does not need to disappear completely.
Add the rice and broth, 8 minutes. Tip in the rice and stir for about 30 seconds to coat the grains in the tomato mixture. Pour in the hot stock and add the remaining measured salt. Bring the liquid to a steady simmer, then reduce the heat to medium-low. Cook uncovered for 8 minutes, stirring once or twice gently so rice does not stick, while keeping the liquid at a lively but controlled simmer.
Cook the monkfish with the rice, 10 minutes. Nestle the monkfish pieces into the rice and broth, distributing them around the pot. Simmer uncovered for another 10 minutes, or until the rice is tender and the fish is opaque and flakes apart easily. Check the thickest piece with a food thermometer: USDA FSIS lists 145°F (63°C) as the safe minimum internal temperature for fish. If the rice is not tender when the fish reaches temperature, lift the fish onto a clean plate and continue cooking the rice briefly, then return the fish to the pot.
Finish and serve, 2 minutes. Remove the bay leaf. Stir in the chopped cilantro and lemon juice, then taste and adjust the salt or lemon. The finished rice should be moist and loose, with a little broth visible around the grains; add a splash of hot stock or water if it has become too thick. Let it stand for 2 minutes, then ladle into warm bowls and serve promptly.

Tips

Choose the right rice texture. Portuguese carolino rice is a traditional choice because its starch helps create a creamy, brothy consistency while the grains remain distinct. It can be difficult to find outside Portuguese or specialty markets. Medium-grain rice is a practical substitute; short-grain rice also works but may become softer. Long-grain rice will be less creamy and can make the result feel more like a conventional pilaf.
Keep extra broth hot. Rice absorbs liquid at different rates depending on its variety, age, and the width of the pot. Keep a little extra stock or water warm and add it in small splashes if the pot looks dry before the rice is tender. Avoid pouring in a large amount at once, which can leave the rice soupy before the grains have finished cooking.
Cut the fish evenly and avoid overcooking it. Similar-sized monkfish pieces cook more consistently. Add them only after the rice has started simmering, as directed, rather than leaving them in the pot for the full rice-cooking time. Monkfish is firm, but it can still turn dry or rubbery if cooked well past the safe temperature.
Use a sensible stock substitute. If seafood stock is unavailable, use a mild vegetable broth or water with a small amount of concentrated fish stock. Strong, salty stock can overwhelm the delicate fish and make it difficult to season accurately, so taste the broth first and reduce the added salt if needed.

Serving Suggestions

Serve Portuguese monkfish rice hot in deep bowls so each portion includes rice, fish, and plenty of the tomato-scented cooking liquid. Put extra cilantro, lemon wedges, and a small dish of red pepper flakes on the table, allowing everyone to adjust the brightness and heat. A simple green salad dressed with olive oil and vinegar balances the richness without competing with the seafood.

Crusty bread is useful for soaking up the remaining broth. If you want a fuller meal, add a plate of steamed green vegetables or lightly sautéed greens on the side. Keep accompaniments fairly simple: the rice itself is already seasoned and substantial, and strong sauces can mask the monkfish and the sweet, savory tomato base.

Variations

For a more elaborate seafood rice, add peeled raw shrimp during the final 5 to 6 minutes of simmering, arranging them among the monkfish pieces. They should turn opaque and reach 145°F (63°C) as well; check a thick piece with a food thermometer. Clams or mussels are another possible addition, but they release liquid and can change the pot’s seasoning, so use fresh, properly handled shellfish and cook until the shells open, discarding any that remain closed.

For a version without wine, replace the ½ cup (120 ml) with an equal amount of extra stock and add a teaspoon of lemon juice or mild vinegar to provide some acidity. The flavor will be a little less rounded, but the tomato and broth still make a good base. If carolino rice is unavailable, medium-grain rice is the closest practical swap. You can also make the dish mildly spicy with extra pepper flakes, or omit them entirely for a gentler, family-style pot.

Storage and Reheating

Rice dishes should not sit at room temperature for long. Refrigerate leftovers within 2 hours of cooking, transferring them to shallow airtight containers so they cool promptly. Store for 3 to 4 days in the refrigerator. The rice will continue to absorb broth as it sits, so leftovers will be thicker than the freshly cooked dish.

Reheat only the portion you plan to eat, either in a saucepan over medium-low heat or in the microwave, stirring periodically. Add a splash of water or seafood stock to loosen the rice, cover loosely to limit splattering, and heat until steaming throughout and at least 165°F (74°C), the USDA FSIS safe temperature for reheated leftovers. Check the center with a food thermometer. Freezing is possible for up to about 2 months, although the rice may soften and the monkfish can become less tender after thawing. Thaw overnight in the refrigerator and reheat to 165°F (74°C).

Frequently Asked Questions

What is Portuguese monkfish rice called?
It is commonly called arroz de tamboril in Portuguese: arroz means rice, and tamboril means monkfish. Recipes vary, but many versions combine monkfish with rice, tomato, aromatics, broth, and fresh herbs in a loose, spoonable preparation.

Can I use frozen monkfish?
Yes. Thaw it fully in the refrigerator, then pat it dry before cutting and cooking. Excess surface water can dilute the seasoned base and make the fish harder to brown or handle. Do not thaw seafood on the counter; if you need a quicker method, keep it sealed and submerge it in cold water, changing the water every 30 minutes, then cook it promptly.

Can I prepare the dish ahead?
The tomato base can be made a day ahead and refrigerated, but cook the rice and fish just before serving for the best texture. Rice continues to absorb broth after cooking, and monkfish can become firmer with extended holding. If you do make the complete dish ahead, cool and refrigerate it promptly, then reheat thoroughly with extra broth.

Why is my rice too dry or too soupy?
Rice variety, pot width, and simmer strength all affect how quickly liquid evaporates. If the grains are still firm and the pot is dry, add hot stock a little at a time and keep simmering. If the rice is tender but the dish looks thicker than you prefer, stir in hot broth just before serving. Aim for a loose consistency, since it thickens during the brief rest and again as it cools.

Can I use another fish instead of monkfish?
Yes. Choose a firm, mild fish that can hold its shape, such as cod loin or halibut, and cut it into pieces of similar size. More delicate fillets may break apart as the rice simmers, so nestle them in gently and check them early with a thermometer. Whatever fish you choose, cook it to 145°F (63°C).
