01 - Heat olive oil in a large deep skillet or Dutch oven over medium heat. Add sliced sausage and cook until browned, about 4–5 minutes. Remove sausage with a slotted spoon and set aside.
02 - In the same pot, add onion and bell pepper. Sauté until softened, about 3–4 minutes. Add garlic and cook for 30 seconds until fragrant.
03 - Stir in Cajun seasoning, smoked paprika, salt, and black pepper. Return the sausage to the pot and mix to coat with the spices.
04 - Add uncooked pasta, chicken broth, and heavy cream. Stir well, scraping any browned bits from the bottom.
05 - Bring to a gentle boil, then reduce heat to low. Cover and simmer for 12–14 minutes, stirring occasionally, until pasta is al dente and most of the liquid is absorbed.
06 - Remove from heat. Stir in Parmesan cheese until creamy. Taste and adjust seasoning if needed.
07 - Garnish with chopped parsley and serve hot.
