Full Ingredients

For the Saffron Rice

2 cups (400 g) Spanish bomba rice, unrinsed
5 cups (1.2 liters) low-sodium seafood stock
Up to 1/2 cup (120 ml) additional seafood stock, kept hot, only if needed
1/2 teaspoon (0.2 g) saffron threads, lightly crushed between your fingertips
3/4 teaspoon fine sea salt, plus more to taste depending on the stock
1/4 teaspoon freshly ground black pepper

For the Tomato and Pepper Base

4 tablespoons (60 ml) extra-virgin olive oil
1 large red bell pepper (180 g), cored and cut into 1/4-inch (6 mm) strips
4 garlic cloves (12 g), finely minced
1 1/2 teaspoons sweet smoked paprika
1 1/2 cups (300 g) freshly grated ripe tomatoes, skins discarded

For the Seafood

2 pounds (900 g) live mussels, shell-on, scrubbed and debearded
1 pound (450 g) skinless, boneless firm white fish, such as monkfish, haddock, or thick-cut cod, cut into 1-inch (2.5 cm) pieces
8 ounces (225 g) cleaned calamari, tubes cut into 1/2-inch (1 cm) rings; small tentacles left whole

For Serving

2 tablespoons (8 g) chopped fresh flat-leaf parsley
1 large lemon, cut into 6 wedges

Equipment: Use a 15-inch (38 cm) stovetop-safe paella pan, a small saucepan, and heavy-duty foil. A similarly wide, shallow skillet also works, but avoid a deep saucepan: the rice needs a broad, relatively thin cooking layer. All cooking is done on the stovetop; no oven is required.

Step-by-Step Instructions

Step 1: Prepare the ingredients and infuse the stock

Measure and chop the ingredients before you begin cooking. To grate the tomatoes, halve them across their middles and grate the cut sides against the large holes of a box grater, stopping when only the skins remain. Measure 1 1/2 cups (300 g) of tomato pulp and juice.

Pour the 5 cups (1.2 liters) of seafood stock into a small saucepan and add the lightly crushed saffron. Heat over medium heat for 5 minutes, until steaming and just below a simmer. Reduce the heat to low and keep warm. Warm the optional extra stock separately if you expect to need it.

Step 2: Clean and check the seafood

Scrub the mussels under cold running water and pull away any beards. Discard mussels with cracked shells, along with any open mussels that do not close when tapped firmly. Do not soak them in fresh water.

Check the fish for bones and cut it into 1-inch (2.5 cm) pieces. Pat the fish and calamari dry with paper towels. Keep all the prepared seafood covered in the refrigerator until it is time to add it to the pan.

Step 3: Build the tomato and pepper base

Place the paella pan over medium heat and add the olive oil. Let it warm for 1 minute, then add the pepper strips and cook for 5 minutes, stirring occasionally, until beginning to soften.

Add the garlic and cook for 30 seconds. Stir in the smoked paprika for 15 seconds, then immediately add the grated tomatoes so the paprika does not burn. Cook for 5 minutes, stirring often, until the tomatoes thicken and the mixture looks glossy rather than watery. This concentrated base is the sofrito.

Step 4: Add the rice and saffron stock

Add the unrinsed bomba rice and stir for 1 minute, coating the grains with the sofrito. Pour in all 5 cups of hot saffron stock, including the saffron threads. Add the sea salt and black pepper, remembering that the mussels will contribute some saltiness later.

Increase the heat to medium-high and bring to a lively simmer, about 2 minutes. Spread the rice into an even layer with a spoon. From this point onward, do not stir the rice. You may gently rotate the pan to help it cook evenly.

Step 5: Cook the rice uncovered

Cook uncovered over medium-high heat for 5 minutes, then reduce to medium and cook for another 7 minutes. The liquid should bubble steadily across the pan without boiling violently. Rotate the pan a quarter turn every few minutes if your burner heats the center more strongly than the edges.

At the end of these 12 minutes, the rice should have absorbed much of the stock but still look moist between the grains. If the pan is already dry and the rice is still hard, drizzle in 2 tablespoons of hot reserved stock around the dry areas before adding the seafood.

Step 6: Add the fish, mussels, and calamari in stages

Nestle the fish pieces into the moist rice in an even layer. Arrange the mussels around them, with the hinged ends tucked into the rice and room for the shells to open. Cover the pan tightly with heavy-duty foil, taking care around the hot handles, and reduce the heat to medium-low. Cook for 8 minutes.

Carefully lift the foil away from your face to release the steam. Arrange the calamari rings and tentacles over the rice, pressing them lightly into any remaining liquid without stirring. Cover again and cook for 4 minutes.

The fish and calamari should be opaque and reach 145°F (63°C) in their thickest parts. The mussels should be open with fully cooked, opaque flesh; discard any that remain closed. The rice should be tender with a slight bite, not hard or chalky. If necessary, remove seafood that is already cooked, add hot stock in 2-tablespoon increments, and cook the covered rice in additional 2-minute intervals.

Step 7: Create a light golden crust

Remove the foil and check the bottom of the pan at one edge with a spoon. If the rice is tender and no loose liquid remains, increase the heat to medium-high for 30 seconds. Listen for a gentle crackle and watch for a lightly toasted aroma, then immediately remove the pan from the heat.

This toasted bottom layer is called socarrat. It is a lovely bonus, not a requirement. Skip this step if the rice already smells toasted, and stop immediately if you smell burning. If a little liquid remains, let it evaporate over medium heat before attempting the crust.

Step 8: Rest, garnish, and serve

Loosely cover the pan with foil and let the paella rest off the heat for 5 minutes. This gives the rice time to settle and absorb the last traces of moisture without trapping too much steam.

Scatter the chopped parsley over the top and arrange the lemon wedges around the edge. Serve straight from the pan, giving everyone a mixture of rice, fish, calamari, mussels, and a little of the toasted bottom layer. Let each person squeeze over lemon to taste.

Pro Tips

Choose bomba rice when possible: It absorbs plenty of flavorful stock while keeping its shape. Other Spanish paella rices may need a different amount of liquid; follow the package guidance and keep hot stock nearby.
Use a wide pan and suitable burner: A 15-inch pan works best over a broad burner or two burners set to similar heat. Rotate carefully using oven mitts to prevent hot spots.
Avoid stirring after adding the stock: Stirring encourages starch release and can turn the rice creamy rather than distinct and tender.
Protect the delicate seafood: Add calamari only near the end, and remove any fish or shellfish that finishes before the rice does.
Trust the pan as well as the clock: Burner strength and evaporation vary. Add extra stock only when the rice needs it, and never force a crust on rice that is already scorching.

Variations

Shrimp instead of calamari: Substitute 8 ounces (225 g) large peeled, deveined raw shrimp. Add them during the final 4 minutes, then check that they are opaque and reach 145°F (63°C); cook a little longer if needed.
A little extra heat: Replace 1/4 teaspoon of the sweet smoked paprika with 1/4 teaspoon hot smoked paprika. Keep the total paprika at 1 1/2 teaspoons.
Yellow pepper variation: Replace half the red pepper with an equal weight of yellow bell pepper for a slightly different flavor and a colorful finish.

Storage & Make-Ahead

Make ahead: Prepare the tomato-pepper sofrito and saffron stock up to 2 days ahead. Cool promptly and refrigerate separately in covered containers. Reheat the sofrito in the paella pan and bring the stock back to steaming before continuing. For the best texture, cook the rice and seafood just before serving.

Store: Remove leftover mussels from their shells and transfer the paella to shallow containers. Refrigerate promptly, ideally within 1 hour and always within 2 hours of cooking. Keep at 40°F (4°C) or below and eat within 1 day for best quality and conservative cooked-rice handling.

Reheat: Add 1 tablespoon of water or stock per serving, cover, and microwave in 1-minute intervals, gently turning the rice between intervals, until it reaches 165°F (74°C) throughout. Reheat only once. The seafood will be firmer, and the original crisp bottom will soften. Freezing is not recommended for the best seafood texture.
