01 - Heat 1 tablespoon oil in a large skillet or Dutch oven over medium-high heat. Add sliced sausage and cook until browned, about 5 minutes. Remove sausage with a slotted spoon and set aside.
02 - Add the remaining oil to the same pan. Sauté onion, bell pepper, and celery for 4-5 minutes until softened. Add garlic and cook for 30 seconds, until fragrant.
03 - Stir in the rice and toast for 1 minute, stirring often. Add tomato paste, paprika, thyme, Creole seasoning, salt, and black pepper. Mix well to combine.
04 - Pour in chicken broth, scraping any browned bits from the bottom. Bring to a boil. Reduce heat, cover, and simmer for 18 minutes, until rice is just tender.
05 - Uncover, gently stir in the shrimp and cooked sausage. Lay shrimp on top of the rice, cover, and cook 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 scallions and parsley. Serve hot.
