1. Bring a large pot of salted water to a boil and cook penne according to package directions until al dente. Reserve 1/2 cup (120 ml) pasta cooking water, drain pasta, and set aside. 2. Pat chicken dry, season evenly with 1 tbsp (15 ml) Cajun seasoning, salt, and pepper. In a large skillet over medium-high heat, heat olive oil until shimmering. Sear chicken 4–5 minutes per side until cooked through and golden. Transfer to a cutting board, let rest 5 minutes, then slice into strips. 3. In the same skillet, reduce heat to medium and add butter. Sauté onion and bell peppers until softened, about 5 minutes. Add garlic and cook 30 seconds until fragrant. 4. Stir in tomato paste, smoked paprika, remaining 1 tbsp (15 ml) Cajun seasoning, and cayenne; cook 1 minute. Pour in chicken broth and deglaze the pan, scraping browned bits. 5. Add heavy cream and Worcestershire sauce; simmer gently until sauce begins to thicken, about 4–6 minutes. Stir in Parmesan and lemon juice; season with salt and pepper. 6. Add cooked pasta and sliced chicken to the skillet. Toss to combine, adding reserved pasta water a few tablespoons at a time if the sauce needs loosening. Adjust seasoning. 7. Serve immediately, topped with extra grated Parmesan and chopped parsley.
