There are weeknight dinners that simply get food on the table, and then there are weeknight dinners that make everyone stop mid-bite and ask, “Wait — did you actually make this?” This One Pot Creamy Cajun Chicken Pasta is firmly in the second category. It is the kind of dish that feels like something you ordered at a restaurant — deeply flavorful, beautifully sauced, and layered with just the right amount of heat — but it comes together in a single skillet in about 45 minutes. On a Tuesday. With minimal cleanup. That alone is reason to celebrate.
The inspiration here is pure Louisiana soul: smoky andouille sausage, tender bites of Cajun-spiced chicken, sweet bell peppers, and a silky cream sauce that wraps every strand of pasta in something close to magic. This is comfort food in the truest sense, but it is also a balanced, nourishing meal built on real whole ingredients. At Eating Happiness, we believe that eating well does not mean eating bland, and this recipe is one of our favorite examples of that philosophy in action. Bold spices, quality protein, colorful vegetables, and a cream sauce made without any shortcuts — this is a dish that loves you back.
Whether you are feeding a hungry family on a weeknight, meal prepping for the week, or just treating yourself to a genuinely satisfying dinner, this one pot wonder delivers every single time. The magic of cooking the pasta directly in the broth and cream means the starch thickens the sauce naturally, creating that luscious, restaurant-quality consistency without any extra effort. Once you make this, it will earn a permanent spot in your rotation. Let’s get into it.

Key Ingredients
The soul of this dish starts with boneless, skinless chicken breast — a lean, high-quality protein that soaks up the Cajun seasoning beautifully and stays juicy when cooked properly over medium-high heat. Alongside the chicken, andouille sausage is the real flavor anchor of this recipe. This smoked, spiced sausage is a cornerstone of Louisiana cooking, and its deep, smoky heat infuses the entire pan as it renders, building a savory base that nothing else can quite replicate. If you want to understand more about the role andouille plays in Southern cuisine, Serious Eats has an excellent breakdown of Cajun sausage traditions that is well worth a read.
The Cajun seasoning blend ties everything together — a mix of smoked paprika, garlic powder, onion powder, cayenne, oregano, and thyme that transforms simple ingredients into something that tastes like it took hours to develop. Using a generous hand with the seasoning is encouraged here; this is not the place to be timid. Bell peppers — ideally a mix of red, yellow, and green — add crunch, color, and a natural sweetness that plays beautifully against the spice. They also bring a meaningful dose of vitamin C and antioxidants to the bowl, which fits perfectly with our clean-eating philosophy here at Eating Happiness.
The sauce comes together with chicken broth and heavy cream, which cook down with the pasta to create that glossy, velvety finish. Using good-quality chicken broth here makes a noticeable difference — it deepens the flavor of the entire dish. Finally, freshly grated Parmesan cheese stirred in at the end adds a salty, nutty richness that binds the sauce and adds just enough indulgence to make this dish feel truly special.

Pro Tips & Variations
Choose the right pasta shape: Penne, rotini, or rigatoni work best here because the ridges and tubes trap the creamy sauce beautifully. Thin pasta like spaghetti or linguine tends to clump in one-pot cooking and does not hold the sauce as well.
Don’t skip searing the meat: Getting a proper golden sear on both the chicken and the andouille before adding liquid is what develops that deep, caramelized flavor in the base of the sauce. Resist the urge to stir too early — let it sit and build color. For more on the science of a perfect sear, Food Network’s guide to searing meat is a great resource.
Control the heat level: The heat in this dish is balanced but real. If you are cooking for heat-sensitive eaters or children, reduce the cayenne in your Cajun seasoning and choose a mild andouille. If you want more fire, add a pinch of red pepper flakes or a dash of hot sauce at the end.
Make it lighter: Swap the heavy cream for half-and-half or full-fat coconut milk for a slightly lighter version that still delivers creaminess. The coconut milk adds a subtle, interesting note that actually works beautifully with the Cajun spices.
Add more vegetables: This dish is very forgiving with additions. Baby spinach wilted in at the end, diced zucchini, corn kernels, or even sun-dried tomatoes all work wonderfully and boost the nutritional profile. If you love building vegetable-forward one-pan dinners, our Garlic Butter Chicken Bites and Potatoes skillet dinner is another great example of that approach.
Swap the protein: No andouille? Smoked kielbasa or even diced bacon work as substitutes, though they will change the flavor profile slightly. For a lighter option, skip the sausage entirely and double the chicken, using extra Cajun seasoning to compensate for the depth the andouille would have brought.
Liquid ratio matters: The key to one-pot pasta is getting the liquid-to-pasta ratio right. Add the broth and cream as directed, and resist adding extra liquid too soon — the pasta will absorb more than you expect. If it looks a little dry before the pasta is fully cooked, add broth a quarter cup at a time rather than pouring in a large amount at once.
Finish with fresh herbs: A handful of freshly chopped flat-leaf parsley or sliced green onions scattered over the top right before serving adds brightness, color, and a fresh counterpoint to the richness of the cream sauce. Do not skip this — it makes a real difference in the final dish.
Nutritional Highlights
This One Pot Creamy Cajun Chicken Pasta is a genuinely balanced meal that leans into the Eating Happiness philosophy of nourishing food that also tastes extraordinary. Each serving delivers approximately 42 grams of protein between the chicken breast and andouille sausage — making it a genuinely satisfying, muscle-supporting meal that will keep you full for hours. The bell peppers contribute a meaningful dose of vitamin C, beta-carotene, and antioxidants, while the Cajun spice blend — particularly the turmeric, paprika, and cayenne — brings its own set of anti-inflammatory benefits. The cream sauce is an indulgent element, and we embrace it as a worth-it moment: rich, real, satisfying, and made without any processed shortcuts. If you enjoy building high-protein, flavor-forward weeknight dinners, you might also love our Crockpot Chicken Tortilla Soup — another protein-packed, bold-flavored option that practically makes itself.
Frequently Asked Questions
Can I make One Pot Creamy Cajun Chicken Pasta ahead of time?
Yes, and it reheats beautifully. Cook the dish fully, let it cool, and store it in an airtight container in the refrigerator for up to 4 days. When reheating, add a splash of chicken broth or a little cream to the skillet over medium-low heat and stir gently as it warms — this revives the sauce and prevents the pasta from drying out. The flavors actually deepen overnight, making this an excellent meal prep option for busy weeks.
What can I substitute for andouille sausage?
Andouille sausage is ideal because of its distinctive smoky, spiced flavor, but there are good alternatives. Smoked kielbasa is the closest substitute in terms of texture and smokiness — just add a little extra Cajun seasoning to compensate. Diced smoked turkey sausage works well for a lighter option. If you cannot find any smoked sausage, a generous amount of quality bacon or pancetta, rendered until crispy and crumbled over the finished dish, adds a similar depth. For a fully chicken-based version, simply double the chicken and increase the Cajun seasoning.
How do I prevent the pasta from getting mushy?
The key is to cook the pasta just to al dente — it should still have a slight bite when you remove the pan from the heat, because it will continue to absorb liquid and soften as the dish rests and as you stir in the Parmesan. Use a timer and start checking the pasta 2 minutes before the package instructions suggest it should be done. Also, keep the heat at a steady medium so the liquid maintains a gentle simmer rather than a rolling boil — aggressive boiling tends to cook pasta unevenly in one-pot preparations.

One Pot Creamy Cajun Chicken Pasta
A bold, smoky, and creamy Cajun chicken pasta cooked entirely in one skillet with andouille sausage, colorful bell peppers, and penne pasta in a rich, spiced cream sauce. Ready in 45 minutes with minimal cleanup.
Ingredients
- 1.25 lbs boneless skinless chicken breast (cut into 1-inch bite-sized pieces)
- 12 oz andouille sausage (sliced into 1/4-inch rounds)
- 1 red bell pepper (thinly sliced)
- 1 yellow bell pepper (thinly sliced)
- 1 green bell pepper (thinly sliced)
- 1 medium yellow onion (diced)
- 5 cloves garlic (minced)
- 1 can (14 oz) diced tomatoes (drained)
- 12 oz penne pasta (dry, uncooked)
- 2 cups chicken broth (low sodium preferred)
- 1.5 cups heavy cream
- 0.75 cup Parmesan cheese (freshly grated)
- 2 tablespoons olive oil (divided)
- 2 teaspoons smoked paprika
- 1.5 teaspoons garlic powder
- 1 teaspoon onion powder
- 1 teaspoon dried oregano
- 0.5 teaspoon dried thyme
- 0.5 teaspoon cayenne pepper (adjust to taste)
- 1 teaspoon kosher salt (plus more to taste)
- 0.5 teaspoon black pepper (freshly ground)
- 3 tablespoons fresh flat-leaf parsley (chopped, for garnish)
- 2 green onions (thinly sliced, for garnish)
Instructions
- In a small bowl, combine all Cajun seasoning ingredients and mix well. Toss the chicken pieces with half the seasoning blend until evenly coated.
- Heat 1 tablespoon of olive oil in a large, deep skillet or Dutch oven over medium-high heat until shimmering. Add the chicken in a single layer and sear for 3 to 4 minutes without stirring until golden brown. Flip and cook another 2 to 3 minutes. Remove chicken to a plate and set aside — it does not need to be fully cooked through at this stage.
- In the same skillet, add the sliced andouille sausage. Cook over medium-high heat for 2 to 3 minutes per side until nicely browned and the fat has rendered. Remove to the plate with the chicken.
- Reduce heat to medium. Add the remaining tablespoon of olive oil. Add the diced onion and cook for 3 minutes until softened and translucent. Add the sliced bell peppers and cook for another 3 to 4 minutes, stirring occasionally, until slightly softened.
- Add the minced garlic and remaining Cajun seasoning blend. Stir and cook for 1 minute until fragrant.
- Stir in the drained diced tomatoes and cook for 2 minutes, scraping up any browned bits from the bottom of the pan.
- Pour in the chicken broth and heavy cream. Stir to combine. Bring the mixture to a gentle boil over medium-high heat.
- Add the dry penne pasta, stirring to submerge it in the liquid. Reduce heat to medium, cover the skillet with a lid, and cook for 12 to 14 minutes, stirring every 3 to 4 minutes to prevent sticking, until the pasta is al dente and most of the liquid has been absorbed into a thick, creamy sauce.
- Return the seared chicken and andouille to the skillet. Stir everything together and cook for 2 to 3 minutes over medium heat until the chicken is cooked through (internal temperature of 165°F) and everything is heated through.
- Remove from heat. Stir in the freshly grated Parmesan cheese until melted and the sauce is silky. Taste and adjust seasoning with salt and pepper as needed.
- Garnish generously with fresh chopped parsley and sliced green onions. Serve immediately straight from the skillet.
