01 - Heat 1 tablespoon vegetable oil in a large skillet or Dutch oven over medium-high heat. Add sliced andouille sausage and cook until well-browned, approximately 5 minutes. Transfer sausage to a plate using a slotted spoon, leaving rendered fat in the pan.
02 - Add remaining tablespoon of oil to the same pan. Sauté diced onion, green bell pepper, and celery for 4 to 5 minutes until softened and fragrant. Add minced garlic and cook for 30 seconds, stirring constantly to prevent burning.
03 - Stir in long grain white rice, toasting for 1 minute while stirring frequently. Add tomato paste, paprika, dried thyme, Creole seasoning, salt, and black pepper. Mix thoroughly to coat rice evenly and distribute spices throughout the mixture.
04 - Pour in chicken broth, using a wooden spoon to scrape up any browned bits from the pan bottom. Bring liquid to a boil, then reduce heat to low. Cover tightly and simmer for 18 minutes, or until rice is tender and liquid has been absorbed.
05 - Uncover pan and gently nestle shrimp and cooked sausage into the rice. Arrange shrimp on top, replace cover, and cook for 5 to 7 minutes until shrimp turn pink and opaque. Remove from heat immediately to prevent overcooking.
06 - Fluff rice mixture gently with a fork. Sprinkle sliced scallions and chopped fresh parsley over the top. Serve immediately while hot, directly from the cooking vessel.
