This one pot creamy Cajun chicken pasta has become one of my go-to dinners on busy weeknights. It’s the kind of dish that delivers big flavor with minimal effort. Everything comes together in a single pan, which means fewer dishes and more time to enjoy with family. The smoky spices, creamy sauce, and tender chicken make it feel special, even though it’s super simple to pull off.
I first whipped this up on a cold Monday when we had barely anything left in the fridge. My husband raved about it and asked me to make it again the next day. That’s when I knew it was a keeper.

- Garlic powder: enhances overall savory notes
- Onion powder: adds another layer of flavor
- Cayenne pepper: brings the heat and excitement
- Black pepper: boosts the spice blend
- Salt: balances all the flavors
- Olive oil: keeps the chicken from sticking and adds a fruity richness
- Butter: makes everything taste better and adds creaminess
- Boneless skinless chicken breasts: are lean and cook quickly

Step-by-Step Instructions
- Season the Chicken:
- Mix smoked paprika oregano thyme garlic powder onion powder cayenne black pepper and salt in a small bowl. Cut the chicken into small cubes and coat them evenly with the spice blend. Let it sit while preparing your pan.
- Sear the Chicken:
- Heat olive oil and butter in a deep skillet over medium-high heat until the butter is fully melted. Add the seasoned chicken and sear each side for a couple of minutes until slightly golden. It does not need to be cooked all the way through at this point.
- Sauté the Onion:
- Add diced yellow onion to the skillet and sauté for two minutes until it starts softening. Let the juices help lift the browned bits from the bottom of the pan. This adds flavor to the final dish.
- Simmer the Pasta:
- Add uncooked penne fire roasted diced tomatoes with juices and chicken broth to the skillet. Stir everything together then cover and bring to a boil. Once boiling reduce the heat and simmer for ten minutes stirring every few minutes until pasta is tender and liquid has reduced into a sauce.
- Finish with Cream Cheese:
- Cut cream cheese into chunks and stir them into the hot pasta until fully melted and blended. The sauce should turn creamy and thick. Sprinkle with sliced green onions before serving.

One of my favorite things about this recipe is how the fire roasted tomatoes give it a smoky background. The first time I made this I remember my son trying to sneak seconds straight from the pan. That memory always makes me smile when I cook it again.
Storage Tips
Store leftovers in an airtight container in the fridge for up to four days. When reheating add a splash of broth or milk to loosen the sauce again. It also freezes surprisingly well though the pasta may soften slightly when thawed.

Ingredient Substitutions
Use chicken thighs instead of breasts for a richer flavor Swap cream cheese with half and half if you prefer a lighter texture Try different pasta shapes like rotini or rigatoni if penne is unavailable
Serving Suggestions
Serve with a green salad or crusty bread to round out the meal. A tangy Caesar salad pairs perfectly with the creamy pasta. Or try a slice of cornbread to balance the Cajun heat with a touch of sweetness.
Cultural Context
Cajun cuisine originated in Louisiana and blends French southern and African influences. Its spice-forward flavor profiles and one pot cooking traditions make it perfect for busy families. This dish honors that tradition with a creamy twist.
