Ingredients You’ll Need

For the Spaghetti

• 1 lb spaghetti

For the Chicken

• 2 lb boneless skinless chicken breasts, cut into thick chunks
• 1 tsp garlic powder
• ½ tsp salt
• ½ tsp black pepper
• 1-2 tbsp Cajun seasoning (for that signature spiced flavor — adjust to taste)
• 1 tbsp olive oil (for searing)

For the Creamy Sauce

• 2½ cups heavy cream
• 4 oz cream cheese, softened and cubed
• 2 cups shredded mozzarella cheese
• 1½ cups grated Parmesan cheese
• ¼ cup tomato sauce
• ½ tsp salt
• ½ tsp black pepper

Note: A bit of Cajun seasoning and a touch of olive oil for searing have been added to the chicken to bring out the bold, spiced flavor the dish is named for — feel free to adjust the amount of Cajun seasoning up or down based on your personal spice preference.

Step-by-Step Instructions

Step 1: Cook the Spaghetti

Bring a large pot of salted water to a boil. Add the spaghetti and cook according to package instructions until al dente, usually 9-11 minutes. Before draining, reserve about 1 cup of the starchy pasta water, which will help adjust the sauce’s consistency later. Drain and set the spaghetti aside.

Step 2: Season and Sear the Chicken

Pat the chicken chunks dry with paper towels to remove excess moisture — this helps achieve a good sear. In a small bowl, combine the garlic powder, salt, black pepper, and Cajun seasoning. Toss the chicken chunks in this seasoning blend until evenly coated.

Heat the olive oil in a large skillet over medium-high heat until shimmering. Add the chicken in a single layer, working in batches if necessary to avoid overcrowding the pan. Sear for 4-5 minutes per side, until golden brown on the outside and cooked through to an internal temperature of 165°F.

Remove the chicken from the skillet and set aside on a plate, tenting loosely with foil to keep warm. Leave any browned bits in the skillet, as they’ll add extra flavor to the sauce.

Step 3: Build the Cream Sauce

Reduce the heat to medium-low. Pour the heavy cream directly into the skillet, stirring to combine with the browned bits left behind from the chicken. Let the mixture come to a gentle simmer — avoid boiling, as this can cause the cream to separate.

Add the softened, cubed cream cheese, stirring continuously until it fully melts and incorporates smoothly into the cream.

Step 4: Add the Tomato Sauce and Seasoning

Stir in the tomato sauce, along with the additional ½ teaspoon salt and ½ teaspoon black pepper. The tomato sauce adds a subtle tang and warmth to the dish without turning it into a full tomato-based sauce — it should remain primarily creamy with just a hint of color and acidity from the tomato.

Step 5: Melt in the Cheeses

Gradually add the shredded mozzarella and grated Parmesan, a handful at a time, stirring continuously and allowing each addition to fully melt before adding more. This gradual method is key to achieving a smooth, glossy sauce rather than a clumpy or oily one.

Continue simmering for 3-5 minutes, stirring occasionally, until the sauce is thick and creamy, coating the back of a spoon. Taste and adjust seasoning as needed.

Pro Tip: If the sauce becomes too thick, thin it out with a splash of the reserved pasta water until you reach your desired consistency.

Step 6: Combine Everything

Add the cooked, drained spaghetti directly into the skillet with the creamy sauce. Using tongs, toss thoroughly until every strand of pasta is well coated.

Slice the seared chicken chunks, if desired, and fold them back into the skillet along with any accumulated juices, gently tossing until evenly distributed and heated through.

Step 7: Serve

Remove the skillet from heat and serve immediately while hot, straight from the pan. For an extra finishing touch, top with a sprinkle of additional Parmesan or a light dusting of Cajun seasoning.

Tips for the Best Cajun Chicken Spaghetti

• Cut chicken into evenly sized chunks. This ensures every piece cooks at the same rate, avoiding overcooked or undercooked pieces.
• Don’t skip patting the chicken dry. Removing excess moisture before seasoning and searing helps achieve a deeper, more flavorful crust.
• Add the tomato sauce gradually. Since this dish is meant to stay primarily creamy, start with the listed amount of tomato sauce and adjust only slightly if you’d like a touch more tang or color.
• Add cheese slowly, in stages. This prevents clumping and helps create a silky, well-emulsified sauce.
• Keep the heat moderate throughout the sauce-making process. High heat is the most common cause of a broken or grainy cream sauce.
• Adjust the Cajun seasoning to your taste. Start with 1 tablespoon for a milder flavor, and work up to 2 tablespoons for a bolder, spicier dish.

Recipe Variations to Try

• Shrimp Swap: Replace the chicken with large shrimp, searing for just 2-3 minutes per side, for a Cajun shrimp pasta variation.
• Extra Spicy: Add a pinch of cayenne pepper or red pepper flakes to the sauce for additional heat.
• Veggie Additions: Stir in sautéed bell peppers, onions, or mushrooms for extra flavor, texture, and color.
• Sausage Addition: Add sliced andouille or smoked sausage along with the chicken for a heartier, more traditional Cajun-inspired flavor.
• Lighter Version: Substitute half of the heavy cream with whole milk for a slightly lighter sauce, though it will be less rich.
• Baked Finish: Transfer the finished pasta to a baking dish, top with extra shredded mozzarella, and broil for 3-5 minutes until golden and bubbly.

What to Serve with This Dish

Round out this creamy, spiced pasta with a few simple sides:

• A crisp green salad with a light vinaigrette to balance the richness
• Garlic bread or a warm crusty baguette for soaking up extra sauce
• Steamed broccoli or roasted asparagus
• A cold glass of sweet tea or a crisp white wine, such as Pinot Grigio, to complement the Cajun spice

Storing and Reheating Leftovers

Storing: Store leftovers in an airtight container in the refrigerator for up to 3-4 days.

Reheating: Cream-based sauces tend to thicken significantly once chilled. Reheat gently on the stovetop over low heat, stirring frequently and adding a splash of milk or cream to loosen the sauce as needed. Microwave reheating also works, in 30-second intervals, stirring between each.

Freezing: Freezing is not strongly recommended for this dish, as the rich cream and cheese sauce can separate or turn grainy upon thawing and reheating.

Frequently Asked Questions

How spicy is this dish? With 1-2 tablespoons of Cajun seasoning, this dish has a mild to moderate level of heat. Adjust the amount up or down based on your personal spice preference.

Can I use chicken thighs instead of chicken breast? Yes — boneless, skinless chicken thighs work well in this recipe and tend to stay extra juicy, though they may require a slightly longer sear time depending on thickness.

Why is my sauce grainy or separated? This is typically caused by cooking the sauce at too high a heat or adding the cheese too quickly. Keep the heat at medium-low and add the cheeses gradually, stirring constantly, for the smoothest results.

Can I use a different pasta shape? Yes — while spaghetti works beautifully in this recipe, fettuccine, linguine, or penne would all be great substitutes.

Can I make this dish ahead of time? This dish is best enjoyed fresh, as the sauce is creamiest right after cooking. If needed, you can season and sear the chicken in advance and prepare the sauce and pasta fresh when ready to serve.
