Creamy One Pot Cajun Chicken Pasta
This one pot Cajun chicken pasta brings smoky, spicy flavor and a velvety cream sauce together in one pan. Tender chicken, bell peppers, and penne simmer in seasoned broth until the pasta is perfectly coated and the kitchen smells incredible.
It’s a 30 minute weeknight dinner that feels like a weekend splurge, with almost no cleanup. If your family likes bold, creamy pasta dishes, this one will go into heavy rotation.
Why This One Pot Pasta Works
The Cajun seasoning does the heavy lifting, giving you layers of warmth, not just sharp heat. The cream mellows everything into a sauce that clings to each piece of chicken and every tube of pasta, so every bite is richly seasoned.
Cooking the pasta right in the pot with the broth and chicken means the starch thickens the sauce without any extra steps. The seared chicken leaves behind browned bits that build a deeper, more complex flavor, while the bell peppers and onion add sweetness to balance the spices.
Ingredients
- 1 lb boneless, skinless chicken breasts, cut into 1-inch pieces: thighs work too and stay extra juicy
- 1 tbsp Cajun seasoning, divided: use your favorite brand or a homemade blend
- Salt and black pepper: season lightly as the Cajun mix already has salt
- 2 tbsp olive oil: for searing and sautéing
- 1 small yellow onion, diced: about 1 cup
- 1 red bell pepper, diced: or any color bell pepper you have
- 3 cloves garlic, minced: fresh garlic is best here
- 2½ cups chicken broth: low sodium so you can control the salt
- 1 cup heavy cream: half and half works but the sauce will be thinner
- 8 oz penne pasta: other short shapes like fusilli or farfalle are fine
- ½ cup grated Parmesan cheese: use a block and grate it yourself for a smooth sauce
- Fresh parsley or sliced green onions, for garnish: adds a fresh pop at the end
Variations / Substitutions
- Protein: Swap the chicken for 1 lb large shrimp (add them in the last 3 minutes of simmering) or use sliced smoked sausage for a more traditional Cajun flavor.
- Dairy free: Use full fat canned coconut milk instead of heavy cream and skip the Parmesan; the sauce will be slightly thinner but still creamy and flavorful.
- Extra heat: Stir in ¼ tsp cayenne pepper with the Cajun seasoning or serve with your favorite hot sauce.
- Veggie loaded: Toss in a handful of spinach at the end when you add the cream, or stir in drained canned diced tomatoes.
- Pasta shape: Fusilli, rigatoni, or farfalle all work well; you may need to adjust the simmer time by a minute or two.

How to Make Creamy One Pot Cajun Chicken Pasta
Step 1: Sear the Chicken
Season the chicken pieces with half of the Cajun seasoning and a pinch of salt. Heat the 2 tablespoons of olive oil in a large pot or Dutch oven over medium high heat. Add the chicken in a single layer and cook for about 5 minutes, turning once, until golden brown on the outside but not cooked through. Transfer the chicken to a plate and set it aside.
The chicken will finish cooking later when it simmers with the pasta. You’re looking for a deep sear that leaves little browned bits stuck to the bottom of the pot. Those bits are loaded with flavor and will dissolve into the sauce.
Step 2: Sauté the Vegetables
With the pot still over medium high heat, add the diced onion and bell pepper. Cook, stirring a few times, for 3 to 4 minutes until they soften and the onion looks translucent. Stir in the minced garlic and the remaining Cajun seasoning and cook for 30 seconds, just until the garlic smells fragrant and the spices darken slightly.
A splash of chicken broth can help lift any overly dark spots from the pot, but the vegetables usually release enough moisture on their own. The seasoning will smell smoky and a little earthy at this point, which is exactly what you want.
Step 3: Simmer the Pasta
Pour in the 2½ cups of chicken broth and bring the mixture to a boil. Add the 8 oz of penne and return the chicken, along with any juices from the plate, to the pot. Lower the heat so the liquid is at a gentle simmer, cover the pot, and cook for 12 to 15 minutes. Stir once or twice during cooking to keep the pasta from sticking.
The penne will soak up the seasoned broth and release starch, which naturally thickens the sauce. Keep an eye on it near the 12 minute mark. You want a little bit of liquid left in the bottom of the pot, so the cream can pull everything together at the end.
Step 4: Finish with Parmesan and Serve
Turn off the heat completely. Stir in the 1 cup heavy cream and the ½ cup grated Parmesan until the sauce turns silky and coats the pasta evenly. Taste and adjust with a pinch more salt or a crack of black pepper if needed. Spoon into warm bowls and scatter fresh parsley or green onions on top.
The sauce will be creamy with a soft pink tint from the Cajun spices, and the chicken will be tender and fully cooked. Serve it right away while it’s hot and the sauce is at its glossiest.
A Few Tips for the Best One Pot Pasta
- Grate the cheese yourself: pre shredded Parmesan often contains anti caking agents that can make the sauce grainy. A minute with a box grater gives you a much smoother finish.
- Watch the salt: many Cajun seasoning blends are already salty. Taste before you add extra salt, and use low sodium broth if you can.
- Don’t let it scorch: if the liquid cooks off too fast before the pasta is tender, add a splash more broth or water and lower the heat a touch.
- Add a smoky layer: if your Cajun seasoning is mild on smokiness, stir in ½ teaspoon of smoked paprika when you sauté the vegetables.
- Leftover love: this pasta thickens as it sits. When reheating, stir in a tablespoon or two of milk or broth to bring back the creaminess.
Simmer times for common pasta shapes:
| Pasta Shape | Simmer Time (mins) |
|---|---|
| Penne | 12-15 |
| Fusilli | 12-14 |
| Farfalle | 11-13 |
| Rotini | 10-12 |
Storing and Reheating Leftovers
- Refrigerate: store in an airtight container for up to 4 days. The pasta will absorb more liquid as it sits, so it will be thicker the next day.
- Reheating: warm gently in a saucepan over low heat with a splash of milk or broth, or microwave in short bursts, stirring between each. Avoid boiling or the sauce may break.
- Serve cold: it’s not recommended; the cream sauce is best served warm.
What to Serve with This Pasta
A crisp green salad with a simple lemon vinaigrette cuts the richness of the cream sauce beautifully. Roasted broccoli or green beans tossed with a little olive oil and salt also work well, adding a fresh, crunchy contrast to the creamy pasta.
Frequently Asked Questions
Can I use milk instead of heavy cream?
You can, but the sauce won’t be as thick or rich. Use whole milk and consider stirring in a teaspoon of cornstarch dissolved in a little cold milk to help it cling to the pasta.
Can I make this dairy free?
Yes, replace the heavy cream with full fat canned coconut milk and skip the Parmesan. The flavor will shift slightly but still be creamy and satisfying.
What if my pasta is too spicy for little kids?
Use a teaspoon or less of Cajun seasoning and stir in a little extra cream or a pat of butter at the end to tame the heat. You can always serve hot sauce on the side for the grown ups.
Can I use pre cooked or leftover chicken?
Absolutely. Dice it and add it when you would normally return the seared chicken to the pot, then warm it through as the pasta simmers.
