01 - Cook pasta in a large pot of salted boiling water until al dente. Drain thoroughly and set aside.
02 - Heat 1 tbsp olive oil in a large skillet over medium-high heat. Season chicken strips with half the Cajun seasoning, paprika, thyme, salt, and pepper. Sauté until golden brown and cooked through, approximately 5–6 minutes. Remove from skillet and set aside.
03 - In the same skillet, add sliced andouille sausage and cook for 2–3 minutes until edges are browned. Remove and combine with the cooked chicken.
04 - Add remaining olive oil to the skillet. Cook bell peppers, red onion, and minced garlic until softened and fragrant, about 3–4 minutes.
05 - Reduce heat to medium. Pour in chicken broth and deglaze the pan, scraping up browned bits. Add heavy cream and remaining Cajun seasoning. Bring to a gentle simmer.
06 - Stir in grated Parmesan cheese until fully melted and sauce begins to thicken, approximately 2–3 minutes.
07 - Return cooked chicken and sausage to the skillet. Add drained pasta and toss everything together until evenly coated in the creamy Cajun sauce.
08 - Taste the dish and adjust salt, pepper, or Cajun seasoning as desired.
09 - Plate the pasta while hot. Top with chopped fresh parsley and sliced green onion for color and freshness.
