Instructions
Prepare the Pasta Base: Bring a large pot of salted water to a rolling boil. Add the penne pasta and cook according to the package instructions until it reaches an al dente texture, meaning tender but with a slight bite in the center. This ensures the pasta will not turn mushy when mixed into the sauce later. Once cooked, drain the pasta well in a colander, drizzle lightly with a touch of olive oil (optional to prevent sticking), and set it aside until needed.
Season the Chicken Thoroughly: Place the diced chicken breast into a large mixing bowl or a resealable plastic bag. Sprinkle over 3 teaspoons of Cajun seasoning, ¼ teaspoon of salt, and ¼ teaspoon of black pepper. Toss or shake well until every piece of chicken is evenly coated in the spices. This step not only infuses the chicken with flavor before cooking but also helps form a delicious golden crust when seared in the pan. Set aside to marinate briefly while you prepare the pan.
Sear the Chicken to Perfection: Heat a large skillet over medium heat and melt 2 tablespoons of butter until it begins to sizzle slightly. Carefully place the seasoned chicken pieces into the hot pan, making sure not to overcrowd them (cook in two batches if necessary). Allow the chicken to cook undisturbed for a few minutes to develop a golden-brown sear, then flip and cook until the pieces are browned on all sides and just cooked through. Transfer the chicken to a clean plate and cover loosely with foil to keep warm while you prepare the vegetables.
Sauté the Vegetables for Flavor: In the same skillet, add the remaining 1 tablespoon of butter. Once melted, stir in the diced onion and sliced bell peppers. Cook the vegetables for 3–5 minutes, stirring frequently, until they begin to soften and release their natural sweetness. The onions should turn translucent, and the peppers should still hold a slight crunch for texture. This step builds the aromatic base of the sauce.
Create the Creamy Cajun Sauce: Reduce the heat slightly and pour in the heavy cream, stirring gently to combine with the vegetables. Season the sauce with the remaining 1 teaspoon of Cajun seasoning, ¼ teaspoon of salt, ¼ teaspoon of black pepper, smoked paprika, dried basil, and garlic powder. Stir thoroughly so the spices are evenly distributed. Allow the mixture to come to a gentle boil, then reduce the heat to a low simmer. Let it cook for several minutes, stirring occasionally, until the sauce thickens slightly and the flavors meld beautifully.
Combine Chicken, Pasta, and Sauce: Return the seared chicken pieces to the skillet, along with any juices that may have collected on the plate. Add in the freshly grated parmesan cheese and stir gently until it melts smoothly into the sauce. Finally, add the cooked and drained pasta to the pan. Toss everything together with a wooden spoon or tongs, ensuring every piece of pasta is coated in the creamy Cajun sauce and the chicken and vegetables are evenly distributed.
Serve and Garnish Generously: Once everything is combined, taste the pasta and adjust seasoning if needed. For an optional finishing touch, sprinkle with freshly chopped parsley or a little extra parmesan cheese before serving. Serve the Cajun chicken pasta immediately while it’s hot and creamy, pairing it with garlic bread or a crisp green salad if desired.
Notes
Pasta type can be swapped—penne is great, but linguine, fettuccine, or rotini work beautifully.
Cajun seasoning levels can be adjusted for heat—mild blends keep it family-friendly, while spicier ones give a bold kick.
Chicken can be substituted with shrimp, sausage, or even tofu for a different protein option.
Freshly grated parmesan melts more smoothly than pre-shredded varieties.
For extra color and nutrients, consider adding zucchini, mushrooms, or spinach to the mix.
If the sauce thickens too much, stir in a splash of pasta water to loosen it.
