01 - Heat olive oil and butter in a large, deep skillet or Dutch oven over medium heat. Add the andouille sausage and cook for 3-4 minutes until browned. Remove with a slotted spoon and set aside.
02 - In the same pan, add onion, bell pepper, and celery. Sauté for 4-5 minutes until softened. Add garlic and cook for 1 minute more.
03 - Stir in the Arborio rice and cook for 2 minutes, stirring constantly, until the grains are well coated and slightly translucent.
04 - Add tomato paste and diced tomato; cook for another minute.
05 - Pour in the white wine, stirring until almost completely absorbed.
06 - Begin adding the warm chicken stock, one ladleful at a time, stirring frequently and allowing each addition to be absorbed before adding the next. Continue until the rice is creamy and al dente, about 20-25 minutes.
07 - Stir in the Creole seasoning, smoked paprika, cayenne, and season with salt and pepper.
08 - Add the cooked sausage and shrimp to the pan. Cook for 3-4 minutes, stirring gently, until the shrimp are pink and just cooked through.
09 - Remove from heat. Stir in fresh parsley. Serve immediately, garnished with lemon wedges and extra parsley if desired.
