Start by gathering and preparing all your ingredients. Ensure the shrimp is peeled and deveined. Chop the bell pepper into small pieces and crush the garlic cloves. Slice the green olives and mince the parsley.
In a large pot or Dutch oven, heat the vegetable oil over medium heat. Once the oil is hot, add the shrimp and sauté for about 3-4 minutes until they turn pink and opaque. Remove the shrimp from the pot and set them aside.
In the same pot, add the bell pepper and crushed garlic. Sauté for 2-3 minutes until the vegetables are tender and fragrant.
Add the tomato sauce and sliced green olives to the pot, stirring to combine. Season with salt and let it cook for another 2 minutes, allowing the flavors to meld.
Stir in the rice, ensuring it’s well coated with the sauce mixture. Pour in 8 cups of water (or follow the rice package instructions for liquid ratios). Bring the mixture to a boil.
Once boiling, reduce the heat to low, cover the pot, and let it simmer for about 20-25 minutes, or until the rice is cooked and has absorbed the liquid.
After the rice is cooked, gently fold in the sautéed shrimp and minced parsley. Cover the pot for an additional 5 minutes to let the flavors combine and the shrimp heat through.
Fluff the rice with a fork, serve hot, and enjoy your delicious Locrio de Camarones with your favorite sides or on its own.
