Follow these simple steps to create your One Pot Cajun Chicken Pasta:

1. Heat the Oil: In a large pot or skillet, heat the olive oil over medium heat.
2. Cook the Chicken: Add the cubed chicken breasts and season with salt and pepper. Cook until browned, about 5-7 minutes. Remove the chicken and set it aside.
3. Sauté Vegetables: In the same pot, add the diced onion and bell pepper. Sauté until softened, about 3-4 minutes. Stir in the minced garlic and cook for an additional minute.
4. Add Pasta: Return the chicken to the pot, then add the uncooked pasta, diced tomatoes (with juices), chicken broth, Cajun seasoning, and smoked paprika. Stir well to combine.
5. Simmer: Bring the mixture to a boil, then reduce the heat to low. Cover the pot and let it simmer for about 12-15 minutes, or until the pasta is cooked and has absorbed most of the liquid.
6. Stir in Cream: Once the pasta is cooked, stir in the heavy cream and grated Parmesan cheese. Mix until creamy and well combined.
7. Adjust Seasoning: Taste and adjust the seasoning with more salt, pepper, or Cajun seasoning if needed.
8. Garnish: Remove from heat and garnish with freshly chopped parsley before serving.
