Helpful Tools
Having the right tools makes all the difference. Here are three essentials for this recipe:

Pro-Tips for Perfect One Pot Cajun Chicken Pasta
- Don’t skip the cornstarch slurry—it’s what gives the sauce that perfect creamy consistency without being too thin.
- Brown the chicken well before removing it from the pot; those caramelized bits add incredible depth to the final dish.
- Always cook pasta in the sauce rather than separately. This allows the noodles to absorb all those wonderful Cajun flavors.
- Feel free to adjust the Cajun seasoning to your heat preference. Start with less if you’re sensitive to spice, then add more at the end if needed.

How to Make One Pot Cajun Chicken Pasta
- Heat 1 tablespoon of olive oil in a large pot over medium-high heat. Toss the chicken pieces with 1/2 tablespoon of Cajun seasoning, then add to the pot in a single layer. Cook until browned on the bottom, about 3 minutes, then flip and cook through, about 3 minutes more. Transfer to foil and wrap to keep warm.
- In the same pot, heat the remaining 1/2 tablespoon of olive oil over medium-high heat. Add the sliced bell peppers and onion, sautéing for about 3 minutes until they begin to soften.
- Add the minced garlic and remaining 1 tablespoon of Cajun seasoning. Sauté for 1 minute more until fragrant.
- Pour in the chicken broth, fire-roasted tomatoes, and 1/2 cup of heavy cream. Bring the mixture to a boil, then add the penne pasta.
- Cook, stirring frequently, until the pasta is nearly tender, about 12-13 minutes. The pasta will continue cooking in the next step.
- Add the cornstarch-water mixture and cook until the pasta is just tender and the sauce has thickened, about 1 minute more.
- Remove from heat and stir in the remaining 1/4 cup of cream, parmesan cheese, fresh parsley, and the cooked chicken. Season with salt and freshly ground black pepper to taste.
- Serve immediately while hot and creamy.
Variations to Try
Once you’ve mastered the classic version, try these delicious variations:
- Swap chicken for shrimp and reduce cooking time to prevent overcooking the seafood.
- Add sliced andouille sausage for an even more authentic Cajun experience.
- Make it vegetarian by using vegetable broth and adding mushrooms instead of chicken for a meaty texture.
