Ingredients

For the Chicken and Pasta:

1 lb. penne pasta (or 454g)
1.5 lbs. boneless, skinless chicken breasts, cut into bite-sized pieces (680g)
2 tablespoons Cajun seasoning (divided)
2 tablespoons olive oil
3 tablespoons unsalted butter

For the Sauce:

1 medium yellow onion, diced (about 1 cup)
1 red bell pepper, sliced into thin strips
1 yellow bell pepper, sliced into thin strips
4 cloves garlic, minced
1 cup chicken broth (240ml)
2 cups heavy cream (480ml)
1/2 cup grated Parmesan cheese (50g)
1 teaspoon paprika
Salt and black pepper to taste
Fresh parsley for garnish

The Cajun seasoning provides the signature spicy-smoky flavor profile, while heavy cream creates that silky, restaurant-quality texture. Fresh bell peppers add sweetness and crunch that balances the heat perfectly.

Pro Tips

Season generously and in layers. Apply Cajun seasoning directly to the chicken pieces before cooking, then add more to the sauce. This layering technique ensures bold flavor throughout rather than just on the surface. Pat the chicken dry before seasoning to help the spices adhere better and achieve superior browning.

Don’t overcook the chicken. Cut pieces to uniform size (about 1-inch cubes) so they cook evenly. Remove chicken from the pan when just cooked through, as it will continue cooking slightly from residual heat. Overcooked chicken becomes rubbery and diminishes the overall dish quality.

Control your sauce consistency. If your Cajun chicken penne pasta sauce becomes too thick, add chicken broth in small increments. If it’s too thin, let it simmer uncovered for a few extra minutes or add a touch more Parmesan. The sauce should coat the back of a spoon but still flow easily. Remember that the sauce thickens as it cools, so aim for slightly looser than your desired final consistency.

Step by Step Instructions

Step 1: Prepare the Pasta

Bring a large pot of salted water to a rolling boil. Add the penne pasta and cook according to package directions until al dente, typically 11-13 minutes. Reserve 1 cup of pasta water before draining, as this starchy liquid can help adjust sauce consistency later. Drain the pasta and set aside, tossing with a small drizzle of olive oil to prevent sticking.

Step 2: Season and Cook the Chicken

Pat the chicken pieces completely dry with paper towels. Place them in a bowl and toss with 1 tablespoon of Cajun seasoning, ensuring even coating on all sides. Heat olive oil in a large, deep skillet or sauté pan over medium-high heat. Once the oil shimmers, add the chicken in a single layer without overcrowding. Cook for 5-6 minutes, turning occasionally, until golden brown on all sides and cooked through (internal temperature of 165°F/74°C). Remove chicken to a plate and set aside.

Step 3: Sauté the Vegetables

Reduce heat to medium and add butter to the same skillet. Once melted and foaming, add the diced onion and sliced bell peppers. Sauté for 4-5 minutes until the vegetables soften and the onions become translucent. Add the minced garlic and remaining tablespoon of Cajun seasoning, stirring constantly for about 30 seconds until fragrant. This aromatic base builds incredible depth for your creamy Cajun pasta sauce.

Step 4: Build the Sauce

Pour in the chicken broth, scraping the bottom of the pan with a wooden spoon to release any flavorful browned bits (this is called deglazing and adds tremendous flavor). Allow the broth to simmer for 2 minutes, then reduce heat to medium-low. Slowly pour in the heavy cream while stirring continuously. Add the paprika, then let the mixture simmer gently for 5-7 minutes, stirring occasionally, until it begins to thicken slightly. The sauce should reduce by about one-third.

Step 5: Combine Everything

Stir the Parmesan cheese into the sauce until completely melted and incorporated. Return the cooked chicken to the skillet along with any accumulated juices. Add the drained penne pasta, tossing everything together until every piece is beautifully coated with the creamy sauce. If the mixture seems dry, add reserved pasta water a few tablespoons at a time until you reach desired consistency. Taste and adjust seasoning with additional salt, pepper, or Cajun seasoning if needed. Let everything heat through for 2-3 minutes, stirring gently.

Step 6: Serve

Remove from heat and garnish generously with freshly chopped parsley and additional Parmesan cheese if desired. Serve immediately while hot for the best texture and flavor experience.

Variations

Cajun Shrimp Penne Pasta: Replace chicken with 1.5 lbs. of large shrimp (peeled and deveined). Season with Cajun spices and sauté for just 2-3 minutes per side until pink and opaque. This seafood version cooks even faster and brings a different protein dimension to the dish.

Lightened Version: Substitute half-and-half or whole milk for the heavy cream and reduce the butter to 1 tablespoon. Add a tablespoon of cream cheese to maintain richness while cutting calories. You can also use whole wheat penne for added fiber and nutrients.

Spicy Garlic Cajun pasta: Double the garlic and add 1/2 teaspoon of red pepper flakes for extra heat. Include 4-5 slices of cooked, crumbled bacon for a smoky depth that complements the Cajun flavors beautifully. This variation brings even more boldness to an already flavorful dish.

Storage and Serving

Store leftover Creamy Cajun Chicken Penne Pasta in an airtight container in the refrigerator for up to 3-4 days. The sauce may thicken considerably when cold, so when reheating, add a splash of chicken broth, milk, or cream to restore the silky consistency. Reheat gently in a skillet over medium-low heat, stirring frequently, or microwave in 1-minute intervals, stirring between each. Freezing is not recommended as cream-based sauces tend to separate and become grainy when thawed.

Serve this creamy pasta with a crisp Caesar salad and warm garlic bread to soak up any extra sauce. A light, citrusy arugula salad with lemon vinaigrette provides a refreshing contrast to the rich, spicy pasta. For a complete Southern-inspired meal, pair with roasted green beans or sautéed collard greens. A chilled glass of Chardonnay or Pinot Grigio complements the cream sauce beautifully, while sweet iced tea offers a non-alcoholic option that balances the heat.

Frequently Asked Questions

Can I use a different pasta shape?

Absolutely! While penne works wonderfully for catching the sauce, you can substitute bow-tie (farfalle), rigatoni, fettuccine, or even rotini. Any pasta with ridges or curves will hold the creamy sauce effectively. Adjust cooking time based on the pasta shape you choose.

How can I make this less spicy?

Reduce the Cajun seasoning to 1-2 teaspoons total, or use a mild Cajun blend. You can also make your own blend with paprika, garlic powder, onion powder, and just a pinch of cayenne. The cream naturally mellows the heat, so adding an extra splash of cream helps too.

Can I make this dairy-free?

Yes, though the texture will differ slightly. Use coconut cream instead of heavy cream and nutritional yeast instead of Parmesan. Choose a dairy-free butter alternative for sautéing. The coconut cream provides richness while complementing the Cajun spices surprisingly well.

Why is my sauce too thin?

This usually happens if the sauce doesn’t simmer long enough to reduce and thicken. Let it bubble gently for a few extra minutes uncovered. Adding the Parmesan cheese should also help thicken it. If still thin, mix 1 tablespoon of cornstarch with 2 tablespoons of cold water and stir into the sauce.

Can I prep this ahead of time?

You can cook the chicken and chop vegetables ahead, storing them separately in the refrigerator for up to 24 hours. However, the sauce and pasta are best combined just before serving. Cream sauces don’t hold well when made too far in advance, as they can separate or become grainy.
