Start by cooking the penne according to package instructions until done.
Next, season the chicken breasts with the Cajun seasoning, making sure to coat both sides evenly.Heat the olive oil in a large pan over medium-high heat, then add the chicken breasts. Cook for about 4 to 5 minutes on each side or until the chicken is cooked through and no longer pink in the center. Remove the chicken from the skillet and set it aside to rest.
In the same skillet, add the sliced bell pepper, diced onion, and minced garlic.Cook for about 3 to 4 minutes or until vegetables are tender. Add the heavy cream and chicken broth to the skillet, stirring to combine.
Slice the cooked chicken breasts into thin strips, then add them to the skillet with the creamy sauce. Stir to coat the chicken in the sauce, then add the cooked penne pasta. Toss everything together until the pasta is well coated in the sauce and heated through.
Taste the pasta and season with salt and pepper as needed. If desired, garnish with fresh chopped parsley for a pop of color and added freshness.
Serve the Creamy Cajun Chicken Pasta hot and enjoy the bold flavors of the Cajun seasoning and creamy sauce. This dish pairs well with a side of garlic bread or a simple green salad.
