This seafood paella builds its flavor from two separate shellfish broths — one from steamed mussels, one from simmered prawn and scampi shells — which combine into the cooking liquid the rice absorbs completely. The result is rice that tastes deeply of the sea without any added stock cubes or shortcuts. It takes about an hour start to finish and feeds four generously, which also makes it one of the better dishes to cook when you want good leftovers for the next day.
The technique that matters
The double-broth method is what separates this from flat, one-dimensional paella. Steaming the mussels first releases a concentrated, briny liquid. Simmering the prawn and scampi shells separately in water draws out a sweeter, richer stock. When you combine those two liquids and use them to cook the rice, every grain absorbs layered seafood flavor that plain water or store-bought broth simply cannot replicate. The other technique worth understanding is the no-stir rule once the saffron goes in. Stirring activates the starch in Bomba or Calasparra rice and turns the texture gluey — the opposite of what you want. Add the liquid, distribute the saffron once, then leave it alone. If you are tempted to stir because it looks dry at the edges, add a small splash of warm broth instead and resist.
Storage and reheating
Leftover paella keeps well in the fridge for up to two days in an airtight container. Remove the mussels from their shells before storing — the shells take up space and the mussels reheat better without them. To reheat, spread the rice in a wide pan, add two or three tablespoons of water, cover with a lid, and warm over low heat for five to six minutes. This steams the rice back to tender without drying it out. Avoid the microwave if you can; it heats unevenly and toughens the prawns. Paella does not freeze well — the rice turns mushy and the seafood goes rubbery — so plan to eat it within two days or scale the recipe down if you know you will not have enough people to finish it.
What can go wrong
- The rice is crunchy in the center but the liquid is gone. This usually means the heat was too high and the broth evaporated before the rice cooked through. Add warm broth in small amounts — about a quarter cup at a time — cover loosely with foil, and give it another three to four minutes on low heat.
- The bottom layer of rice is scorched. A pan that is too thin or a burner that is too small creates hot spots. Use the widest, heaviest pan you have and rotate it a quarter turn every five minutes if your burner does not cover the full base of the pan.
- The sofrito is watery and the rice turns out bland. The tomato sauce needs to cook down until it is visibly thick and paste-like before you add the rice. If it still looks loose after eight minutes, keep going — another two or three minutes makes a real difference to the final flavor.
- The prawns and scampi are rubbery. They go in during the last five minutes for a reason. Adding them too early means they overcook while the rice finishes. If your rice needs more time than expected, pull the shellfish out and add them back for just the final two minutes.
- The saffron flavor is barely noticeable. Bloom the saffron threads in a tablespoon of warm water for five minutes before adding them to the pan — skip the garnish parsley instead and use that dish for blooming the saffron, since the parsley is not worth the extra washing up.
Authentic Seafood Paella: Easy Spanish Recipe
Ingredients
- 2½ cups Bomba rice or Calasparra or Arborio
- 10.5 oz monkfish fillet cut into 2-inch pieces
- 9 oz fresh mussels scrubbed and debearded
- 5.3 oz squid rings
- 5.3 oz whole prawns shell-on (about 8–10 medium)
- 5.3 oz whole scampi (langoustines) shell-on
- ½ large red pepper diced
- ½ large green pepper diced
- 8½ cups water
- 4 medium ripe tomatoes or 200ml passata
- 1 medium onion finely diced
- 2 cloves garlic minced
- 2 pieces bay leaves dried or fresh
- 1 small handful fresh flat-leaf parsley chopped (for garnish)
- 2-3 tablespoons extra virgin olive oil
- 1 pinch salt to taste
- ½ teaspoon saffron threads or ¼ tsp saffron powder
Instructions
- Scrub the mussels under cold running water and remove the beards. Discard any mussels that are cracked or do not close when tapped.
- Place the mussels in a medium pot with 250ml (1 cup) of water. Cover and steam over high heat for 3–4 minutes until all shells open. Discard any that remain closed. Strain and reserve the mussel broth. Set the mussels aside.
- Cut the monkfish into 2-inch (5cm) pieces. If using whole squid, slice into rings.
- Peel and devein the prawns and scampi, reserving all heads and shells. Place the heads and shells in a pot with 500ml (2 cups) of water. Bring to a boil, simmer for 10 minutes, then strain through a fine-mesh sieve. Reserve this shellfish stock.
- Finely dice the onion and garlic. Deseed and finely dice the red and green peppers.
- If using fresh tomatoes, score the base with an X, blanch in boiling water for 30 seconds, peel, and crush or grate to a pulp. Cook the tomato pulp in a small saucepan over medium heat for 6–8 minutes until thickened. Set aside.
- Heat 2–3 tablespoons of olive oil in a 15-inch paella pan or wide skillet over medium heat. Add the garlic and onion with a pinch of salt. Sauté for 3–4 minutes until softened and lightly golden.
- Add the bay leaves and diced peppers. Cook for 4–5 minutes, stirring occasionally, until the peppers are tender.
- Stir in the tomato sauce and squid rings. Cook for 6 minutes until the mixture is thick and the squid has firmed up. Remove and discard the bay leaves. Remove the squid and set aside.
- Press the sofrito through a fine-mesh sieve into a bowl, extracting as much liquid as possible. Discard the solids. Return the strained sofrito to the paella pan.
- Add the squid and monkfish pieces to the pan. Stir in the rice and cook for 2 minutes, ensuring the grains are coated.
- Combine the reserved mussel broth and shellfish stock with 1 litre (4¼ cups) of water. Warm the liquid in a saucepan. Pour roughly half into the paella pan — enough to cover the rice by about 1cm (½ inch).
- Add the saffron threads (or powder) and stir once to distribute evenly. This is the last time you stir the rice.
- Bring to a boil over high heat, then immediately reduce to medium-low. Simmer uncovered for 15–20 minutes without stirring. If the liquid is absorbed before the rice is tender, add warm broth in small amounts.
- When the rice is nearly done (about 5 minutes remaining), nestle the prawns, scampi, and mussels (in their shells) into the rice. Do not stir.
- Continue cooking until the rice is tender and the seafood is heated through. Taste and adjust salt.
- Remove the pan from the heat. Cover loosely with a clean tea towel and rest for 5 minutes. Garnish with chopped parsley and serve immediately from the pan.

Your questions, answered
Can I use frozen seafood instead of fresh?
Yes, but thaw it completely and pat it dry before cooking. Excess water from frozen seafood dilutes the broth and can make the rice soggy, so drying it well is the step most people skip.
What if I can’t find Bomba or Calasparra rice?
Arborio works as a substitute and is listed in the recipe. It absorbs liquid slightly differently and can go a little creamier, so watch the liquid level closely and avoid any stirring.
Do I need a paella pan, or will a regular skillet work?
A regular wide, heavy skillet works fine. The key is surface area — you want the rice spread in a thin, even layer so it cooks uniformly, so use the widest pan you own.
Can I make the broths ahead of time?
Yes, and it actually makes the day-of cooking much faster. Both the mussel broth and the shellfish stock keep in the fridge for up to two days, or you can freeze them for up to a month.
Can I leave out one of the seafood types if I can’t find it?
Yes. The recipe is flexible — if scampi or monkfish are unavailable, increase the quantity of what you do have or swap in another firm-fleshed fish or shellfish. Just keep the total weight roughly the same so the broth-to-rice ratio stays balanced.
