01 - Heat 1 tablespoon vegetable oil in a large skillet or Dutch oven over medium-high heat. Add sliced andouille sausage and cook until browned, approximately 5 minutes. Remove sausage with a slotted spoon and reserve.
02 - Add remaining oil to the same pan. Sauté diced onion, bell pepper, and celery for 4-5 minutes until softened. Add minced garlic and cook for 30 seconds until fragrant.
03 - Stir in long grain white rice and toast for 1 minute, stirring frequently. Add tomato paste, paprika, dried thyme, Creole seasoning, salt, and black pepper. Mix thoroughly to coat rice evenly.
04 - Pour in chicken broth, scraping any browned bits from the bottom of the pan. Bring to a boil, then reduce heat to low. Cover and simmer for 18 minutes until rice is just tender.
05 - Uncover and gently stir in the reserved sausage. Arrange shrimp on top of the rice, cover, and cook for another 5-7 minutes until shrimp are pink and opaque and rice is fully cooked.
06 - Remove from heat. Fluff rice with a fork, garnish with sliced scallions and chopped parsley. Serve immediately while hot.
