Ingredients
Cajun Seasoning Blend (make your own — it’s better)
- 2 tsp (10 ml) smoked paprika
- 1 tsp (5 ml) dried oregano
- 1 tsp (5 ml) dried thyme
- 1 tsp (5 ml) garlic powder
- 1 tsp (5 ml) onion powder
- ½ tsp (2.5 ml) cayenne pepper (reduce to ¼ tsp for mild)
- ½ tsp (2.5 ml) black pepper
- ½ tsp (2.5 ml) kosher salt
Chicken & Pasta
- 1 lb (450 g) boneless, skinless chicken breast — cut into ¾-inch cubes; swap with chicken thighs for juicier results
- 1 tbsp (15 ml) olive oil
- 1 tbsp (14 g) unsalted butter
- 1 medium yellow onion, diced
- 1 red bell pepper, deseeded and thinly sliced
- 1 green bell pepper, deseeded and thinly sliced
- 4 cloves garlic, minced
- 15 oz (425 g) can fire-roasted diced tomatoes, with juices — regular diced tomatoes work, but fire-roasted adds smokiness
- 2 cups (475 ml) low-sodium chicken broth
- 8 oz (225 g) penne pasta, uncooked — or farfalle, rotini, or rigatoni
Cream Sauce Finish
- 2 oz (56 g) full-fat cream cheese, cut into chunks — the secret weapon for a glossy, clingy sauce
- ¼ cup (25 g) freshly grated Parmesan cheese
- ½ cup (120 ml) heavy cream (optional — adds extra richness)
Garnish
- 3 green onions, thinly sliced
- Fresh parsley, chopped
- Extra Parmesan for serving
Step-by-Step Instructions
Make the Cajun seasoning blend. Combine all spices in a small bowl and stir until evenly mixed. This takes 60 seconds and is far better than store-bought — more aromatic, less sodium, and perfectly balanced. [PRO TIP: Make a double batch and store in a jar — you’ll use it on everything from shrimp to roasted vegetables.]
Season and coat the chicken. Place the diced chicken in a bowl, pour the Cajun seasoning over the top, and toss until every piece is fully coated in the spice blend. Let it sit for 5 minutes so the seasoning starts to penetrate the meat.
Sear the chicken until golden. Heat olive oil and butter in a large, deep skillet or Dutch oven over medium-high heat. Add the seasoned chicken in a single layer and cook for 4–5 minutes, stirring occasionally, until golden brown on the outside and just cooked through. The pan should smell incredible at this point — that’s the Cajun spices blooming in the fat. [PRO TIP: Don’t stir too early — let the chicken sit untouched for 2 minutes to build a proper crust before flipping.]
Sauté the aromatics. Push the chicken to the side of the pan (or remove it temporarily), then add the diced onion and bell peppers. Cook for 3–4 minutes, stirring occasionally, until the onion softens and the peppers start to caramelize at the edges. Add the minced garlic and cook for 1 more minute until fragrant.
Deglaze and build the base. Pour in the fire-roasted tomatoes with their juices and stir, scraping up any browned bits from the bottom of the pan — that’s concentrated flavor, not waste. Those fond bits will dissolve into the sauce and make it taste like it simmered for hours.
Add the broth and pasta. Pour in the chicken broth, then add the uncooked pasta. Stir everything together until the pasta is submerged in the liquid. The mixture should look saucy and rust-colored with visible pieces of chicken, pepper, and tomato throughout. [PRO TIP: Make sure the pasta is fully submerged — any pieces sticking out will cook unevenly and turn chewy.]
Simmer until the pasta is tender. Bring to a boil, then reduce heat to medium-low, cover with a lid, and cook for 10–14 minutes, stirring every 3–4 minutes, until the pasta is al dente and the liquid has reduced into a thick, saucy consistency.
Melt in the cream cheese. Add the cream cheese in small chunks directly into the pan. Stir continuously for 1–2 minutes until it fully melts and transforms the sauce into a silky, creamy coating that clings to every piece of pasta. If you’re using heavy cream, stir it in now along with the Parmesan.
Taste and adjust. Give the pasta a final taste and adjust salt, pepper, or cayenne to your liking. The sauce should be bold, smoky, and creamy — with a gentle heat that builds at the back of the throat.
Garnish and serve immediately. Top with sliced green onions, fresh parsley, and extra Parmesan. Serve straight from the pot — this is peak comfort food, and it deserves to be eaten hot.

Expert Tips & Variations
3 Tips for a Flawless Result
Don’t skip the sear. It’s tempting to dump everything in the pot at once, but searing the chicken first creates a crust that locks in juices and builds a layer of caramelized flavor at the bottom of the pan. That browned layer (called fond) dissolves into the broth when you deglaze — it’s the difference between a good pasta and an unforgettable one.
Stir the pasta while it simmers. Unlike boiling pasta in water, one-pot pasta needs attention. Stir every 3–4 minutes so the pasta cooks evenly and doesn’t clump or stick. The starch released during stirring also helps thicken the sauce naturally into a creamy consistency.
Use full-fat cream cheese, not low-fat. Low-fat cream cheese contains more water and stabilizers, which means it won’t melt as smoothly and can create a grainy texture. Full-fat cream cheese melts into a flawless, velvety sauce every single time.
3 Recipe Variations
- Shrimp Cajun pasta: Swap chicken for 1 lb (450 g) of large peeled shrimp. Cook the shrimp for just 2 minutes per side at the start, remove them, then add back in Step 8 to avoid overcooking. The shrimp stay plump and juicy while soaking up the creamy Cajun sauce.
- Dairy-free version: Replace butter with olive oil, cream cheese with a dairy-free alternative (Violife or Kite Hill work well), and Parmesan with nutritional yeast. The sauce stays creamy and rich without any dairy whatsoever.
- Meal prep version: Cook through Step 9, then divide into 4 airtight containers. The pasta will absorb more sauce as it sits — add a splash of chicken broth when reheating to loosen it back up. Stores beautifully for 4 days.
Storage & Reheating
Store leftovers in an airtight container in the fridge for up to 4 days. Freeze in individual portions for up to 2 months — thaw overnight in the fridge before reheating. To reheat, add 2–3 tablespoons of chicken broth or water to the portion, then microwave in 90-second intervals on medium power, stirring between each, until hot. The broth revives the creamy sauce and prevents the pasta from drying out.
FAQ
Q: Can I use store-bought Cajun seasoning instead of making my own?
A: Yes — use about 1½ tablespoons of your preferred Cajun or Creole blend. Just check the sodium level first; many commercial blends are very salty, and since you’re also using salted broth, you may want to reduce or skip any added salt in the recipe. Tony Chachere’s and Slap Ya Mama are both excellent options.
Q: What pasta works best for one pot creamy Cajun chicken pasta?
A: Short, sturdy pasta shapes like penne, rigatoni, farfalle, or rotini are ideal because they hold their shape during the simmer and catch the creamy sauce in their ridges or tubes. Avoid thin pasta like angel hair or spaghetti — they overcook quickly and turn mushy before the sauce has time to develop.
Q: How do I make this recipe gluten-free?
A: Simply swap the regular pasta for your favorite gluten-free penne or rotini. The rest of the recipe is naturally gluten-free — just double-check your chicken broth label, as some brands add wheat-based thickeners. The cooking time may vary by 1–2 minutes depending on your GF pasta brand.
Q: Can I make one pot Cajun chicken pasta with chicken thighs instead of breast?
A: Absolutely — and many cooks actually prefer thighs here. Boneless, skinless chicken thighs are more forgiving, stay juicier during the sear, and add a richer flavor to the overall dish. The cooking time in Step 3 stays the same; just ensure they reach an internal temperature of 165°F (74°C).
Q: Why is my one pot pasta sauce too thick or too thin?
A: If the sauce is too thick, stir in ¼ cup of chicken broth at a time until you reach your desired consistency. If it’s too thin after the pasta is cooked, remove the lid and let it simmer uncovered on medium heat for 3–5 minutes — the sauce will reduce quickly into a glossy, clingy coat. The cream cheese also helps stabilize and thicken the sauce as it melts.
Conclusion
One pot creamy Cajun chicken pasta is everything a weeknight dinner should be — bold, satisfying, packed with protein, and done in 35 minutes with barely any cleanup. It’s the kind of recipe that earns a permanent spot in your rotation after the very first bite.
