Preparation Phase & Tools to Use

Having the right tools makes this recipe much easier while ensuring every ingredient cooks evenly.

Large Dutch Oven or Deep Skillet

A heavy-bottomed pot distributes heat evenly and is large enough to cook the chicken, vegetables, pasta, and sauce together without overcrowding.

Sharp Chef’s Knife

Makes slicing the peppers, onion, and chicken into uniform pieces for even cooking.

Cutting Board

Provides a safe and organized workspace for prepping vegetables and meat.

Wooden Spoon or Silicone Spatula

Perfect for stirring without scratching cookware while helping scrape up flavorful browned bits from the bottom of the pot.

Measuring Cups and Spoons

Essential for balancing the Cajun seasoning, broth, cream, and Parmesan for consistent results.

Small Mixing Bowl

Used to combine the cornstarch and water into a smooth slurry that thickens the sauce without lumps.

Cheese Grater

Freshly grated Parmesan melts much better than pre-shredded cheese, giving the sauce a smoother texture.

Preparation Tips

• Cut the chicken into evenly sized pieces for uniform cooking.
• Slice the peppers and onion thinly so they soften at the same rate as the pasta cooks.
• Use freshly grated Parmesan for the creamiest sauce.
• Stir the pasta occasionally while simmering to prevent sticking.
• Keep the broth at a gentle simmer instead of a rolling boil.
• Taste the Cajun seasoning before adding extra salt since many blends already contain salt.
• Let the finished pasta rest for 2–3 minutes before serving so the sauce thickens naturally.
• Garnish with fresh parsley just before serving for the brightest flavor.

• 1 pound boneless skinless chicken breasts, cut into 1-inch pieces
• 1½ tablespoons Cajun seasoning
• 1 medium red bell pepper, sliced into 2-inch strips
• 1 medium yellow bell pepper, sliced into 2-inch strips
• 1 small red onion (5–6 ounces), halved and thinly sliced
• 2 garlic cloves, minced
• 2 (14.5-ounce) cans low-sodium chicken broth
• 1 (14.5-ounce) can fire-roasted diced tomatoes
• ¾ cup heavy cream, divided

Step 1: Season the Chicken

Place the chicken pieces in a bowl and toss them with the Cajun seasoning until evenly coated.

---

Step 2: Sear the Chicken

Heat 1 tablespoon of olive oil in a large Dutch oven or deep skillet over medium-high heat. Add the seasoned chicken and cook for 5–6 minutes, stirring occasionally, until lightly browned and nearly cooked through. Transfer the chicken to a plate.

---

Step 3: Cook the Vegetables

Add the remaining ½ tablespoon olive oil to the same pot. Stir in the sliced peppers and onion, cooking for about 4–5 minutes until they begin to soften. Add the minced garlic and cook for another 30 seconds until fragrant.

---

Step 4: Add the Liquids

Pour in the chicken broth, fire-roasted diced tomatoes with their juices, and ½ cup of the heavy cream. Stir well while scraping any browned bits from the bottom of the pot.

---

Step 5: Cook the Pasta

Add the uncooked penne pasta and bring the mixture to a gentle boil. Reduce the heat to medium-low and simmer uncovered for about 13–16 minutes, stirring occasionally, until the pasta is tender and most of the liquid has been absorbed.

---

Step 6: Return the Chicken

Add the cooked chicken back into the pot and stir until heated through.

---

Step 7: Thicken the Sauce

Stir together the cornstarch and water until smooth, then mix it into the pasta. Add the remaining ¼ cup heavy cream and continue cooking for 1–2 minutes until the sauce thickens.

---

Step 8: Finish with Parmesan

Reduce the heat to low and gradually stir in the Parmesan cheese until completely melted into the sauce. Taste and adjust with salt and freshly ground black pepper if needed.

---

Step 9: Garnish and Serve

Sprinkle with freshly minced parsley and serve immediately while hot with extra Parmesan on the side if desired.

Notes

• Barilla penne holds its shape especially well in one-pot recipes.
• Freshly grated Parmesan creates a much smoother sauce than pre-packaged cheese.
• Fire-roasted tomatoes add extra depth and smoky flavor.
• If the sauce becomes too thick, stir in a splash of warm chicken broth or milk before serving.
• You can substitute chicken thighs for even juicier meat.
• For a spicier version, add a pinch of cayenne pepper or red pepper flakes.

---

Watch Out for These Mistakes While Cooking

• Overcrowding the pan while browning the chicken, which prevents proper searing.
• Boiling the pasta too aggressively, causing uneven cooking.
• Forgetting to stir occasionally, allowing the pasta to stick.
• Adding Parmesan over high heat, which can make the cheese clump.
• Using pre-shredded Parmesan that doesn’t melt smoothly.
• Overcooking the chicken before returning it to the sauce.
• Adding extra salt before tasting, since Cajun seasoning and Parmesan are naturally salty.
• Skipping the cornstarch slurry if your sauce seems thin.

Frequently Asked Questions

Can I use chicken thighs instead of chicken breasts?

Absolutely. Boneless, skinless chicken thighs work wonderfully in this recipe and often stay even juicier. Cook them the same way until they reach an internal temperature of 165°F (74°C).

Is One Pot Cajun Chicken Pasta very spicy?

It has a mild to medium level of heat. The spice depends on the Cajun seasoning you use. If you prefer a milder dish, reduce the seasoning slightly or choose a mild Cajun blend.

Can I make this recipe ahead of time?

Yes. Prepare the pasta up to two days in advance and store it in the refrigerator. Reheat with a splash of chicken broth or milk to keep the sauce creamy.

What pasta works best besides penne?

Rigatoni, rotini, ziti, or fusilli are all excellent choices because they hold the creamy Cajun sauce well.

Can I add more vegetables?

Definitely. Mushrooms, spinach, zucchini, broccoli, or even corn make delicious additions and blend well with the Cajun flavors.

Why is my sauce too thick?

The pasta continues to absorb liquid as it sits. Simply stir in a little warm chicken broth, milk, or cream while reheating until the desired consistency is reached.

Can I make this lighter?

Yes. Substitute half-and-half for the heavy cream or use evaporated milk for a lighter sauce. Keep in mind the texture will be slightly less rich.

Can I freeze One Pot Cajun Chicken Pasta?

Yes. Freeze it in airtight containers for up to 2 months. Thaw overnight in the refrigerator and reheat gently while stirring in a little cream or broth to refresh the sauce.
