Ingredients

• 1 pound boneless, skinless chicken breasts, cut into bite-sized pieces

• 8 ounces penne pasta

• 2 tablespoons olive oil

• 2 tablespoons unsalted butter

• 1 small yellow onion, finely diced

• 1 red bell pepper, thinly sliced

• 3 garlic cloves, minced

• 2 tablespoons Cajun seasoning, divided

• 2 cups low-sodium chicken broth

• 1 cup heavy cream

• ½ cup freshly grated Parmesan cheese

• ½ teaspoon smoked paprika

• ½ teaspoon Italian seasoning

• ½ teaspoon salt, or to taste

• ¼ teaspoon black pepper

• 2 tablespoons chopped fresh parsley

• ½ cup reserved hot pasta cooking liquid or additional broth, as needed

Ingredient Notes

Chicken breasts: Boneless, skinless chicken breasts cook quickly and are easy to cut into even pieces. Boneless chicken thighs are another good option and provide a slightly richer flavor.

Cajun seasoning: Use your favorite store-bought Cajun blend. Some brands contain considerable salt, so taste before adding extra salt.

Penne pasta: Penne holds creamy sauce nicely, but rotini or rigatoni also work well. Choose regular dried pasta rather than fresh pasta because the cooking method is designed for dried pasta.

Heavy cream: Heavy cream creates a rich sauce and is less likely to separate during simmering than lighter dairy products.

Parmesan cheese: Freshly grated Parmesan melts more smoothly than pre-shredded cheese.

How to Make One-Pan Cajun Chicken Pasta

1. Season the chicken.

Place the chicken pieces in a bowl and toss with 1 tablespoon Cajun seasoning, smoked paprika, black pepper, and a small pinch of salt. Make sure the pieces are evenly coated.

2. Brown the chicken.

Heat olive oil in a large, deep skillet over medium-high heat. Add the seasoned chicken in a single layer and cook for approximately 4–5 minutes, turning occasionally.

The chicken should develop golden-brown edges. It does not need to be completely cooked through yet. Transfer it to a plate.

3. Cook the vegetables.

Reduce the heat to medium and add butter to the same skillet. Stir in the diced onion and sliced red bell pepper. Cook for 3–4 minutes until softened.

Add the minced garlic and cook for another 30 seconds, stirring frequently so it doesn’t burn.

4. Add the pasta and liquid.

Pour in the chicken broth and heavy cream. Stir in the remaining Cajun seasoning and Italian seasoning.

Add the uncooked penne pasta and stir to distribute it evenly. Bring the mixture to a gentle simmer.

5. Simmer until the pasta is tender.

Reduce the heat to medium-low and cover the skillet. Cook for approximately 12–15 minutes, stirring every few minutes to prevent sticking.

Check the pasta near the end of cooking. It should be tender but still hold its shape. If the liquid reduces too quickly before the pasta is cooked, add a little warm broth.

6. Return the chicken to the skillet.

Add the browned chicken and any accumulated juices back into the pan. Stir gently and simmer for another 3–5 minutes, or until the chicken reaches an internal temperature of 165°F (74°C).

7. Finish with Parmesan.

Turn the heat to low. Stir in the grated Parmesan until melted and the sauce becomes creamy.

If the sauce is too thick, add a splash of warm broth or reserved pasta liquid. Taste and adjust the seasoning. Finish with fresh parsley and serve warm.

Expert Tips

• Use a large, deep skillet: A 12-inch skillet with relatively high sides gives the pasta enough room to cook evenly.

• Don’t skip browning: Browning the chicken adds savory flavor to the skillet before the sauce is made.

• Stir regularly: Pasta releases starch as it cooks, which helps thicken the sauce but can also cause sticking.

• Control the heat: Keep the sauce at a gentle simmer rather than a rapid boil to prevent the cream from reducing too quickly.

• Add Parmesan at the end: Lowering the heat before adding cheese helps create a smoother sauce.

• Check Cajun seasoning first: Different blends vary in saltiness and spice level.

Common Mistakes to Avoid

• Using too little liquid: Pasta needs enough liquid to soften. Add warm broth gradually if the skillet becomes dry.

• Boiling the cream too aggressively: High heat can make the sauce reduce too quickly and affect its texture.

• Overcooking the chicken: Remove it while browning and return it near the end to finish cooking gently.

• Adding too much salt: Cajun seasoning and Parmesan already contribute saltiness.

• Skipping the stirring: Pasta can stick to the bottom if left undisturbed for too long.

Easy Variations

• Extra spicy Cajun pasta: Add a pinch of cayenne pepper or red pepper flakes.

• Cajun chicken and spinach pasta: Stir in two handfuls of fresh spinach during the final few minutes.

• Mushroom Cajun pasta: Add 1 cup sliced mushrooms when cooking the onions and bell peppers.

• Cajun sausage pasta: Replace part of the chicken with sliced smoked sausage for a heartier flavor.

• Lighter sauce: Replace some of the heavy cream with whole milk, keeping in mind that the sauce will be thinner.

Ingredient Substitutions

• Chicken thighs: Use boneless, skinless thighs instead of chicken breasts.

• Penne: Rotini, rigatoni, or fusilli are suitable alternatives.

• Heavy cream: Half-and-half can be used, but the sauce will be less rich and may need a little extra Parmesan.

• Chicken broth: Vegetable broth works if you prefer a different base.

• Parmesan: Pecorino Romano can be substituted, although it has a sharper and saltier flavor.

What to Serve With It

• Garlic bread: Great for scooping up the extra Cajun cream sauce.

• Simple green salad: Fresh lettuce, cucumber, and a light vinaigrette balance the richness.

• Roasted broccoli: Adds a slightly crisp vegetable side.

• Steamed green beans: A simple option that doesn’t compete with the bold Cajun seasoning.

Storage & Reheating

Refrigerator: Allow leftovers to cool promptly and transfer them to an airtight container. Refrigerate within 2 hours and enjoy within 3–4 days.

Freezing: Freezing is not ideal because cream-based sauces can separate and pasta may become softer after thawing. Refrigeration is recommended for the best texture.

Reheating: Warm individual portions in a saucepan over low heat or in the microwave in short intervals. Add a splash of milk or chicken broth and stir gently to loosen the sauce.

Avoid overheating, as this can make the chicken dry and the sauce overly thick.

Frequently Asked Questions

1. Can I make Cajun chicken pasta without heavy cream?

Yes. Half-and-half can be used instead, although the sauce will be thinner. You can add a little extra Parmesan to help thicken it.

2. Is One-Pan Cajun Chicken Pasta spicy?

It has a noticeable Cajun flavor with mild to moderate heat, depending on the seasoning blend. Reduce the Cajun seasoning or choose a mild blend for a gentler version.

3. Can I use a different type of pasta?

Yes. Rotini, rigatoni, and fusilli are good alternatives. Cooking times and liquid absorption may vary, so check the pasta as it simmers.

4. Can I use pre-cooked chicken?

Yes. Add cooked chicken during the final few minutes of cooking, just long enough to heat it thoroughly. Since it won’t need browning or additional cooking, avoid simmering it for too long.

5. How do I thicken the Cajun cream sauce?

Allow the pasta to simmer uncovered briefly if there is excess liquid. Parmesan also helps thicken the sauce. Remember that it will become thicker as it cools.

6. Can I prepare this recipe ahead of time?

It’s best served freshly prepared because the pasta continues absorbing sauce as it sits. You can chop the chicken and vegetables and measure the seasonings ahead of time to make dinner preparation easier.

Final Thoughts

One-Pan Cajun Chicken Pasta brings together tender chicken, pasta, colorful vegetables, and a creamy Cajun sauce in one convenient skillet. It’s a satisfying dinner with bold seasoning and simple preparation, making it a useful addition to any weeknight recipe collection.
