Ingredients for One-Pot Spanish Seafood Paella

Instructions

Heat olive oil in a large deep skillet or wide saucepan over medium heat.
Add the onion and red bell pepper; sauté for 4-5 minutes until softened.
Stir in garlic and cook until fragrant, about 1 minute.
Add Arborio rice and stir well to coat the grains evenly with the oil and vegetables.
Pour in the broth, diced tomatoes, smoked paprika, saffron with its soaking water, thyme, salt, and pepper. Stir to combine.
Bring mixture to a gentle simmer, then cover loosely and cook for about 15 minutes without stirring, allowing rice to absorb liquid.
Nestle shrimp, mussels, and squid rings evenly into the simmering rice mixture.
Cover and cook for another 7-10 minutes until seafood is cooked and mussels have opened.
In the last 2 minutes of cooking, sprinkle peas over the top and replace the cover.
Remove from heat and let rest for 5 minutes, covered.
Discard any unopened mussels, fluff the rice gently with a fork, garnish with parsley, and serve with lemon wedges.

For customization or ingredient availability, consider these substitutions while maintaining the dish’s easy, family-friendly, and flavorful qualities:

Seafood: Substitute shrimp, mussels, and squid with firm white fish like cod or halibut, canned clams, or cooked crab meat for milder or convenience options.
Rice: Use bomba or short-grain risotto rice for authentic texture. For low-carb versions, cauliflower rice works with reduced liquids.
Broth: Vegetable broth keeps it pescatarian or vegetarian; low-sodium chicken broth is fine if no restrictions.
Saffron: Turmeric can substitute for color and mild earthiness but saffron provides signature flavor and aroma.
Smoked Paprika: Regular paprika is a fine alternative, though smoky depth is reduced.
Peas: Swap frozen peas for chopped green beans, artichoke hearts, or asparagus for seasonal variation.
Oil: Avocado or sunflower oil may substitute olive oil if preferred.

These facilitate flexibility while honoring dietary preferences like gluten-free and pescatarian to keep this an easy, flavorful weeknight one-pot meal.
