In a 14-inch skillet or paella pan, heat 2 tablespoons olive oil over medium heat. Add the chicken, season with salt and pepper, and brown for about 5-7 minutes. Remove the meat and set aside.
2 tablespoons olive oil, 1 pound boneless, skinless chicken thighs, ½ teaspoon Kosher salt, ¼ teaspoon freshly ground black pepper
In the same pan, add the chorizo and cook until browned. Remove and set aside with the chicken.
8 ounces Spanish chorizo*
Add more olive oil if needed and sauté onion, red bell pepper, and garlic until onion is translucent.
1 onion, 1 red bell pepper, 2 cloves garlic
Stir in the tomatoes and cook for an additional 3 minutes to create the sofrito. Push the sofrito to the sides of the pan.
2 tomatoes
Add the rice to the center of the pan and toast it for 1-2 minutes, then mix it with the sofrito.
1½ cups short-grain Spanish rice**
Pour in the warm chicken broth and saffron, spreading the rice and vegetables evenly in the pan. Do not stir after this point.
4 cups low-sodium chicken broth, 1 pinch saffron threads***
Return the chicken and chorizo to the pan and sprinkle over the smoked paprika and half of the parsley. Gently shake the pan to settle everything.
½ teaspoon smoked paprika, ½ cup finely chopped flat-leaf parsley
Simmer for about 15 minutes.
Then sprinkle the peas over the rice and arrange the shrimp and mussels on top, pushing them down into the rice slightly. Cook for another 10 minutes or until the seafood is cooked and the mussels have opened (discard any that don't open).
½ cup frozen peas, 12 large shrimp****, 1 dozen mussels*****
Remove from heat and cover the paella with a lid or foil. Let it rest for 5 minutes before serving.
Garnish with the remaining parsley and serve with lemon wedges on the side.
