Ingredients for Your One Pot Creamy Cajun Chicken Pasta

  • For the Cajun Seasoning:
  • 2 teaspoons smoked paprika
  • 1 teaspoon dried oregano
  • 1 teaspoon dried thyme
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/4 teaspoon cayenne pepper (or more if you like it spicy!)
  • 1/4 teaspoon black pepper
  • 1/2 teaspoon salt
  • For the Pasta:
  • 1 tablespoon olive oil
  • 1 tablespoon unsalted butter
  • 1 pound boneless skinless chicken breast, cut into 1-inch cubes
  • 1 small yellow onion, diced
  • 3 cloves garlic, minced
  • 8 ounces penne pasta (or your favorite short pasta shape!)
  • 1 can (14.5 ounces) fire-roasted diced tomatoes with their juices

  • 1/2 cup shredded mozzarella cheese
  • 3 green onions, sliced (for that fresh garnish)

Step-by-Step Instructions for the One Pot Creamy Cajun Chicken Pasta Recipe

First things first, let’s get that amazing Cajun flavor going! In a small bowl, just mix up all your spices for the seasoning: smoked paprika, oregano, thyme, garlic powder, onion powder, cayenne pepper, black pepper, and salt. This blend is pure magic, trust me. Then, take your cubed chicken and toss it with this spice mix until every piece is coated. This step is crucial because it really lets those flavors soak into the chicken before it even hits the pan. Want to see some other creamy chicken magic?

Now, grab a big, deep skillet – one you can actually cover. Heat up that olive oil and butter over medium-high heat. Once it’s shimmering, carefully add your seasoned chicken. We want to get a nice little sear on it, so let it cook for about 4 to 5 minutes, stirring now and then. It doesn’t need to be cooked all the way through, just nicely browned on the outside. This browning step builds SO much flavor in the pan, which we’ll use later!

Next, toss in your diced yellow onion and minced garlic. Stir them around with the chicken and let them cook for about 2 minutes until they’re fragrant and just starting to soften. You’ll smell that delicious aroma – that’s dinner calling!

Here comes the fun part – adding the rest of the ingredients for the pasta! Throw in your penne pasta, the can of fire-roasted diced tomatoes (don’t drain them, we want those juices!), and the chicken broth. Give it all a good stir to make sure nothing is sticking to the bottom. Bring this all up to a boil. Once it’s boiling, reduce the heat to medium-low, slap a lid on it, and let it simmer for about 10 to 12 minutes. Remember to stir it every few minutes so the pasta doesn’t clump up and so all that liquid starts to get thick and saucy. It’s like magic happening right in your skillet!

Once the pasta is tender and you’ve got this gorgeous, thick sauce going, it’s time for the creaminess! Stir in your softened cream cheese and shredded mozzarella cheese. Keep stirring until they’re completely melted and you have this incredibly lush, creamy sauce coating everything. If you like a good Tuscan vibe, you might also enjoy my creamy Tuscan chicken skillet!

Let it cook for just another 2 to 3 minutes, stirring occasionally. You want to make sure the chicken is cooked through (safe to eat at 165°F) and that the sauce is perfectly coating every noodle. Give it a taste – does it need a pinch more salt or a whisper more spice? Go for it!

Finally, it’s time to serve! Sprinkle that beautiful pasta generously with your sliced green onions for a pop of freshness and color. Dig in while it’s hot and creamy!

Serving Suggestions for Your One Pot Creamy Cajun Chicken Pasta

This pasta is hearty on its own, but a few little extras can make it even better!

Crusty Bread: You absolutely need something to sop up that incredible creamy sauce. A simple baguette or some garlic bread is perfect.

Simple Green Salad: A light, crisp salad with a tangy vinaigrette cuts through the richness of the pasta beautifully. Think mixed greens with a lemon or lime dressing.

Easy Guacamole: For a fresh, creamy counterpoint, a scoop of my easy guacamole adds healthy fats and amazing flavor without being too heavy.

Grilled Corn Salad: If it’s grilling season, a side of my grilled corn salad brings a sweet, smoky char that’s a delightful contrast to the creamy pasta.

Storing and Reheating Your One Pot Creamy Cajun Chicken Pasta

Got leftovers? Lucky you! Store this deliciousness in an airtight container in the fridge for up to 3 days. The creamy sauce can sometimes thicken up a bit when it cools, so don’t worry if it looks a little different.

When you’re ready to reheat, I really recommend using the stovetop. Just pop your leftovers into a skillet over medium-low heat with a splash of milk or chicken broth – it helps loosen up that sauce and makes it creamy again. Stir it gently until it’s heated through. Microwaving works in a pinch, but try to stir it halfway through to avoid those dried-out bits. For meal prep, I often portion it out into individual containers so grab-and-go lunches are super easy!

Frequently Asked Questions About One Pot Creamy Cajun Chicken Pasta

Can I make this recipe spicier?

Absolutely! If you love a kick, just add more cayenne pepper to your Cajun seasoning blend. You could also add a pinch of red pepper flakes when you sauté the onions and garlic, or even stir in a little hot sauce at the end. My kids can only handle so much heat, but I sometimes add an extra dash of cayenne for myself!

What kind of pasta works best?

I used penne here because the little tubes hold onto that creamy sauce so well, but honestly, almost any short pasta shape will work great! Think rotini, farfalle (bowties), or even shells. Just make sure to follow the cooking time on your pasta package for al dente perfection. It’s all about finding what you have in the pantry!

Can I use chicken thighs instead of breasts?

Yes, you totally can! Chicken thighs are actually a little more forgiving and tend to stay super moist. Just trim off any excess fat and cut them into bite-sized pieces. They might take a minute or two longer to brown, but they’ll be so delicious in the creamy sauce.
