In a glass bowl, combine olive oil, paprika, oregano, salt, and pepper to create a flavorful marinade.
To begin preparing the paella, the cook should start by adding chicken to the dish and stirring it gently until it is evenly coated. Once coated, the mixture should be covered and refrigerated until it is needed later in the cooking process.
In a large skillet or paella pan, heat 2 tablespoons of olive oil over medium heat. Begin by stirring in the garlic and pepper flakes, then proceed to mix in the rice. Continuously stir and cook until the rice is thoroughly coated with oil, which should take around 3 minutes.
The mixture can be enhanced by adding saffron threads, a bay leaf, some parsley, chicken stock, and lemon zest. Thoroughly stir until everything is well combined, then bring the mixture to a boil. Once boiling, reduce the heat to medium-low, cover the pot, and allow it to simmer for approximately 20 minutes.
As the rice simmers, heat up some olive oil in a different skillet over medium heat. Proceed to mix in the marinated chicken and cook it for about 3 minutes. Next, add the onion and continue cooking until it becomes translucent, which usually takes around 5 minutes.
The cook adds bell pepper and sausage to the pan and proceeds to stir, using a spatula to break up the sausage. This process continues for approximately 5 minutes. Next, the cook introduces shrimp into the mix, continuing to stir until the shrimp turn a vibrant pink on the outside and their flesh becomes opaque, which typically takes about 2 minutes.
After preparing the rice mixture, smoothly spread it onto a serving tray. Then, generously layer it with a delightful combination of meat and seafood.
