Ingredients

(Note: All ingredient amounts are listed in the recipe card below.)

2 boneless, skinless chicken breasts: Chicken breasts are quick to cook and absorb the Cajun seasoning well. You could also use thighs for more flavor.
1 tablespoon olive oil: For cooking the chicken. Olive oil adds a mild flavor and helps sear the chicken evenly.
1 tablespoon Cajun seasoning: This is the key to the dish’s bold flavor. You can either use store-bought Cajun seasoning or make your own blend.
Salt and pepper, to taste: Essential for seasoning the chicken and ensuring it has enough flavor.
12 oz penne, fettuccine, or spaghetti: Any long or short pasta will work, but penne and fettuccine are great choices for creamy sauces.
Salt, for the pasta water: Seasoning the pasta water enhances the flavor of the pasta.
2 tablespoons unsalted butter: The butter forms the base of the creamy sauce, adding richness and flavor.
4 cloves garlic, minced: Fresh garlic brings aromatic depth to the sauce.
1 tablespoon Cajun seasoning: Adding Cajun seasoning to the sauce intensifies the dish’s flavor profile.
1 teaspoon smoked paprika: For a smoky flavor that complements the Cajun seasoning and adds depth to the sauce.
1 cup heavy cream: The heavy cream makes the sauce velvety and rich, balancing the heat from the Cajun spices.
½ cup chicken broth: Chicken broth adds a savory base to the sauce and helps thin it out slightly for a smoother texture.
¼ cup grated Parmesan cheese: Parmesan adds a salty, umami depth to the sauce, making it extra flavorful.
Fresh parsley, chopped (optional): For garnish and added freshness.
Red pepper flakes: For an extra kick of heat, sprinkle some red pepper flakes on top.
Fresh lemon juice: A squeeze of lemon just before serving will brighten the dish and balance the richness.
Sautéed vegetables: Add sautéed bell peppers, onions, spinach, or mushrooms for extra flavor and nutrition.
Shrimp: Substitute the chicken with shrimp for a seafood twist on this Cajun pasta.

Directions

1. I start by seasoning the chicken breasts with Cajun seasoning, salt, and pepper on both sides.
2. I heat olive oil in a large skillet over medium-high heat and cook the chicken until golden brown and cooked through, about 5–6 minutes per side. Then I transfer it to a plate to rest.
3. While the chicken rests, I cook the pasta in salted boiling water according to the package directions until al dente. I drain it and set it aside, saving about ½ cup of pasta water.
4. In the same skillet, I melt the butter and sauté the minced garlic until fragrant.
5. I stir in the Cajun seasoning and smoked paprika, letting the spices bloom in the butter for about 30 seconds.
6. I pour in the heavy cream and chicken broth, stirring to combine and scraping up any bits from the pan.
7. Once the sauce starts to simmer, I add the grated Parmesan cheese and stir until it melts and the sauce thickens slightly.
8. I slice the cooked chicken and add it to the sauce along with the drained pasta.
9. I toss everything together, adding a splash of the reserved pasta water if the sauce feels too thick.
10. I finish by squeezing in a bit of fresh lemon juice and topping with chopped parsley and a sprinkle of red pepper flakes before serving.

Servings and Timing

This recipe serves about 4 people. It takes roughly 30 minutes total — around 10 minutes for prep and 20 minutes for cooking.

Variations

When I want to mix things up, I replace the chicken with shrimp or sausage for a different twist. I also like adding colorful bell peppers, mushrooms, or spinach to give the dish extra texture and freshness. For a lighter version, I sometimes swap the heavy cream for half-and-half. If I crave more spice, I double the Cajun seasoning or sprinkle extra red pepper flakes.

Storage/Reheating

I store leftovers in an airtight container in the refrigerator for up to 3 days. When reheating, I add a splash of milk or cream to loosen the sauce and warm it gently on the stovetop or in the microwave. I avoid overheating it to keep the sauce creamy. This dish can also be frozen for up to 2 months; I thaw it in the fridge overnight before reheating.
