Cook the Pasta: Bring a large pot of salted water to a boil. Add fettuccine and cook according to package instructions until al dente. Drain and set aside.
Sauté the Sausage: In a large skillet, heat olive oil over medium heat. Add the sliced andouille sausage and cook until browned, about 5-7 minutes. Remove sausage and set aside.
Cook the Vegetables: In the same skillet, add the chopped onion, diced bell pepper, and garlic. Sauté for about 3-4 minutes until softened and fragrant.
Make the Sauce: Pour in the chicken broth and bring to a simmer. Stir in the heavy cream, Cajun seasoning, and smoked paprika. Simmer for about 5 minutes until the sauce thickens slightly.
Combine: Return the sausage to the skillet. Add the drained fettuccine and Parmesan cheese, stirring well to coat the pasta with the creamy sauce. Season with salt and pepper to taste.
Serve: Divide the creamy Cajun sausage pasta into bowls and garnish with chopped green onions and parsley for a fresh touch.
Notes
Feel free to adjust the spice level by adding more or less Cajun seasoning.
