Cajun Chicken Pasta

This Cajun Chicken Pasta is a creamy, bold weeknight dinner that comes together in about 40 minutes. Golden-seared chicken, colorful bell peppers, and penne pasta are all coated in a rich, spicy cream sauce that’s big on flavor and simple enough to pull together on a busy night.

This recipe is on repeat at my house, and for good reason. The first time I made this version, the dish came out too pale and just didn’t have that bold, craveable look you expect from a Cajun pasta. The fix came down to two things: getting a real sear on the chicken so it builds that golden crust and color, and using the Cajun seasoning twice, once on the chicken before it hits the pan and again in the sauce. That layering is what gives the dish real depth from start to finish rather than just on the surface. Now it’s one of those recipes where it hits the table and everyone is already asking for seconds.

Why This Recipe Works

Getting a good sear on the chicken is what makes the difference between a pasta that looks restaurant-quality and one that just looks and tastes…fine. Patting the chicken completely dry before it goes in the pan and giving the pieces space to brown builds that golden crust and flavor you can actually see and taste.

The second key is using Cajun seasoning in two stages, on the chicken and again in the sauce, so the flavor runs through the whole dish instead of sitting only on the surface. Finally, letting the cream sauce simmer for a few minutes before adding the pasta allows it to thicken just enough to coat every piece of penne instead of pooling at the bottom of the bowl.

Key Ingredients

• Penne pasta: Penne is the right call here. The hollow tubes trap the creamy sauce inside every bite. Any short pasta works in a pinch, but penne is my pick for this recipe.
• Boneless skinless chicken breasts: I cut the chicken into bite-size pieces so every piece gets fully coated in seasoning and browns evenly in the pan.
• Cajun seasoning: I used Slap Ya Mama brand, which has a great balance of heat and flavor without being overpowering. You’ll use it twice: 1.5 tablespoons on the chicken and 1 tablespoon in the sauce. Any good Cajun seasoning works here.
• Red and yellow bell peppers: Slice them into strips so they hold their texture and stay colorful in the finished dish. They add a natural sweetness that balances the heat.
• Heavy cream: This is the base of the sauce and what keeps it rich and saucy. Don’t swap it for half and half if you want the sauce to properly cling to the pasta.
• Freshly grated Parmesan: I highly recommend that you grate it yourself if you can. Pre-shredded cheese has a coating that prevents it from melting as smoothly into the sauce.
• Paprika: Added separately to deepen the smoky flavor alongside the Cajun seasoning.

How to Make Cajun Chicken Pasta

Step 1: Cook the pasta Bring a large pot of salted water to a boil. Cook the penne according to package directions until al dente. Drain well. You can rinse the pasta briefly in cold water to stop the cooking process and keep it from getting mushy.

Step 2: Season and sear the chicken Pat the chicken pieces completely dry with a paper towel, then season evenly with 1.5 tablespoons of Cajun seasoning. Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Add the chicken in a single layer and sear until golden brown, cooked through, and no longer pink inside (internal temperature should reach 165°F). Transfer to a plate and set aside.

Step 3: Saute the vegetables In the same skillet, add the remaining tablespoon of olive oil and the butter. Add the chopped onion and sliced bell peppers and cook for 4 to 5 minutes until softened.

Step 4: Add garlic and spices Add the minced garlic, 1 tablespoon of Cajun seasoning, and smoked paprika. Stir and cook for about 30 seconds until fragrant.

Step 5: Build the sauce Pour in the chicken broth and scrape up any browned bits from the bottom of the pan. Let it simmer for about 2 minutes. Stir in the fresh cracked black pepper. Reduce the heat to medium-low, add the heavy cream, and simmer gently for 3 to 4 minutes until slightly thickened.

Step 6: Add the Parmesan and pasta Stir in 1/2 cup of freshly grated Parmesan until melted and smooth. Add the cooked penne and toss to coat everything in the sauce.

Step 7: Finish and serve Taste and adjust with salt, pepper, or extra Cajun seasoning as needed. Return the cooked chicken to the skillet and stir it in. Garnish with the chopped cilantro and the remaining 2 tablespoons of Parmesan. Serve hot.

Recipe Tips

• Do not crowd the pan. Give the chicken pieces room in the skillet. If they overlap, they will steam instead of sear and you lose all that color and crust that makes this dish look and taste the way it should.
• Let the sauce simmer before adding the pasta. The 3 to 4 minute simmer after adding the cream is what allows it to thicken just enough to coat the penne instead of running to the bottom of the bowl.
• Taste at the end. Cajun seasoning brands vary in salt level, so always taste before serving and adjust. A pinch of extra seasoning or another crack of black pepper can make a real difference.

Serving Suggestions

This pasta is a complete meal on its own, but it pairs really well with a green salad or a piece of crusty bread for scooping up extra sauce. Garlic bread is a great addition if you are feeding a bigger group.

How to Store Cajun Chicken Pasta

• Refrigerator: Store leftovers in an airtight container for up to 3 days. When reheating, add a splash of chicken broth to the skillet over medium-low heat to loosen the sauce and bring it back to a creamy consistency.
• Freezer: Cream-based sauces can separate when frozen, so freezing is not recommended for this dish. If you need to freeze it, use a freezer-safe container for up to 1 month and thaw overnight in the refrigerator before reheating on the stovetop.
• Room Temperature: Do not leave out for more than 2 hours.
