Add the onions, garlic, tomatoes, and paprika and cook, stirring often, until the onions soften, about 6 minutes. Add the saffron and 4 cups of chicken stock. Flip the chicken so it’s skin side up and bring everything to a boil over high heat.
Sprinkle in the rice, distributing evenly, then add the peppers on top. Cook, uncovered, without stirring, until rice has absorbed most of the liquid, about 12-15 minutes. If the pan is larger than the burner, rotate it every two minutes to evenly distribute the heat. Once the stock is low enough, add the remaining 2 cups chicken stock.
Reduce heat to low, and top with the cooked shrimp. Nestle in the clams, hinge side down. Continue to cook, without covering or stirring, until the clams opened and the rice absorbs the liquid and is al dente, 5–10 minutes more. Turn heat to high for 1-2 minutes to create the socarrat. Remove pan from heat, cover with aluminum foil, and let sit for 5 minutes before enjoying.
Notes
Paella is totally customizable so feel free to make this dish vegetarian, all seafood, or all meats.
You also can grate the tomatoes on the largest holes of a box grater. Be careful and discard the skin afterwards.
