Name: Homemade Cast Iron Seafood Paella
Ingredients: ⅓ cup extra-virgin olive oil; 1 large onion (finely diced); 2 garlic cloves (minced); 2 medium tomatoes (peeled and diced); 1.5 tsp sweet paprika (Pimentón de la Vera); 1 pinch saffron threads; 2 large squid (cleaned and sliced into ¼-inch rings); 2 cups short-grain rice (Bomba or Calasparra); 1 cup white wine; 3 cups seafood stock; 12 prawns or jumbo shrimp (shells on); 12 mussels; Fresh parsley and lemon wedges (for serving)

Who Needs a Paella Pan When Cast Iron Does the Job So Well?

Traditional paella is cooked in a wide, shallow pan designed to maximize surface area, helping the rice absorb flavors and develop that coveted crispy bottom known as the socarrat. But if you don’t own a traditional Spanish paella pan, you don’t need to miss out. Your everyday cast-iron skillet is the absolute best alternative.

The heavy mass of cast iron retains heat exceptionally well, allowing you to achieve a deeply flavorful sofrito base, perfectly cooked seafood, and an authentic, crackling socarrat right on your stovetop. This seafood paella brings together sweet prawns, tender mussels, sliced squid, saffron, and short-grain rice for an unforgettable dinner party centerpiece.

By simmering the wine and seafood stock together, layering the aromatics, and arranging the seafood over the rice at just the right moment, you get a restaurant-quality Spanish masterpiece using standard kitchen equipment.

Ingredients

Aromatics: 1 large yellow onion (finely diced) and 2 garlic cloves (minced).
Tomatoes: 2 medium tomatoes (peeled and diced).
Spices: 1.5 teaspoons sweet paprika (such as Pimentón de la Vera/dulce) and a pinch of saffron threads.
Seafood: 2 large squid (cleaned and sliced into ¼-inch rings), 12 prawns or jumbo shrimp (shells on for extra flavor), and 12 mussels.
Rice: 2 cups short-grain rice (such as Bomba, Calasparra, or Arborio as a substitute).
Liquids: 1 cup white wine and 3 cups seafood stock (homemade or high-quality boxed).

Step-by-Step Instructions

Step 1: Simmer the Broth

In a large saucepan over high heat, bring the white wine and seafood stock to a simmer. Add a pinch of saffron threads, then reduce the heat to low and keep the mixture gently simmering.

Step 2: Build the Sofrito

Place a large, shallow frying pan (such as a 10-inch cast iron skillet) over medium-high heat and add the olive oil. When hot, add the diced onion and sauté until translucent, stirring frequently. Add the minced garlic and cook for 1-2 minutes until fragrant (do not let it brown). Stir in the diced tomatoes, sweet paprika, and a pinch of salt. Cook, stirring occasionally, until the tomatoes reduce and the oil begins to sizzle.

Step 3: Sauté the Squid

Gently add the sliced squid to the pan, stirring to coat it in the tomato mixture. Sauté for about 1 minute to give the squid a bit of color.

Step 4: Add the Rice and Broth

Stir in the short-grain rice and cook for 1 minute, then spread the rice evenly across the pan in a thin layer (it will puff up as it absorbs liquid). Pour in the simmering wine and stock mixture all at once. Reduce the heat to low and cook without stirring for 10 minutes.

Step 5: Add the Prawns

Carefully lay the prawns or jumbo shrimp in a circle on top of the rice. Cook for another 10 minutes, turning the shrimp over as they start to turn pink. (If the rice starts to dry out before the shrimp is cooked, top it up with a bit of extra hot stock, half a cup at a time).

Step 6: Steam the Mussels

While the rice finishes, steam the mussels in a separate skillet with a half-inch of simmering water and a tight-fitting lid. They are done when the shells open (be sure to discard any that stay closed). Arrange the cooked mussels decoratively on top of the paella.

Step 7: Form the Socarrat and Rest

When the stock fully evaporates, listen for a faint crackling sound from the bottom of the pan as the socarrat (crispy rice crust) forms. If you don’t hear anything, briefly raise the heat to medium for a short burst. Remove the paella from the heat and cover it with a clean tea towel for 3 minutes to rest. Uncover, garnish with fresh parsley, and serve with lemon wedges!
