Ingredients

- 2 tbsp (30g) Cajun seasoning, divided
- 0.5 tsp (2.5g) salt
- 0.25 tsp (1.2g) black pepper, freshly ground
- 1 lb (450g) penne pasta (or fettuccine), uncooked
- 1 tbsp (15g) salt, for pasta water
- 2 tbsp (30g) unsalted butter
- 1 large (150g) yellow onion, finely diced
- 1 large (200g) red bell pepper, cored, seeded, and diced
- 1 large (200g) green bell pepper, cored, seeded, and diced
- 4 cloves (20g) garlic, minced
- 2 tbsp (30g) tomato paste
- 1 cup (240ml) chicken broth, low sodium
- 2 cups (480ml) heavy cream (or whipping cream), at room temperature
- 0.5 cup (50g) Parmesan cheese, freshly grated
- 0.25 cup (60g) sun-dried tomatoes in oil, drained and chopped (optional)
- 2 cups (60g) fresh spinach, packed (optional)
- 0.25 cup (15g) fresh parsley, chopped, for garnish
Instructions
- Prepare Chicken: Pat chicken cubes dry with paper towels. In a medium bowl, toss the chicken with 1.5 tablespoons (22.5g) Cajun seasoning, 0.5 teaspoon (2.5g) salt, and 0.25 teaspoon (1.2g) black pepper until evenly coated.
- Cook Pasta: Bring a large pot of salted water (1 tbsp / 15g salt) to a rolling boil over high heat. Add the 1 lb (450g) penne pasta. Cook according to package directions for 8-12 minutes, or until al dente (firm to the bite). Drain the pasta, reserving 0.5 cup (120ml) of the pasta water. Toss with 1 tablespoon (15ml) olive oil to prevent sticking.
- Sear Chicken: Heat 1 tablespoon (15ml) olive oil in a large skillet or Dutch oven over medium-high heat until shimmering. Add the seasoned chicken in a single layer. Cook for 5-7 minutes, flipping once, until browned on all sides and cooked through, reaching an internal temperature of 165°F (74°C). Remove chicken from the skillet and set aside.
- Sauté Vegetables: Reduce heat to medium. Add 2 tablespoons (30g) unsalted butter to the same skillet. Add the diced yellow onion, red bell pepper, and green bell pepper. Sauté for 7-9 minutes, stirring occasionally, until the vegetables are softened and slightly translucent.
- Add Aromatics and Seasoning: Stir in 4 cloves (20g) of minced garlic and the remaining 0.5 tablespoon (7.5g) Cajun seasoning. Cook for 1 minute, stirring constantly, until fragrant.
- Build Flavor Base: Stir in 2 tablespoons (30g) of tomato paste and, if using, 0.25 cup (60g) chopped sun-dried tomatoes. Cook for 2-3 minutes, stirring frequently, allowing the tomato paste to deepen in color and caramelize slightly.
- Deglaze and Simmer: Pour in 1 cup (240ml) of low-sodium chicken broth. Scrape the bottom of the pan with a wooden spoon to loosen any browned bits. Bring to a gentle simmer and cook for 2-3 minutes, allowing the liquid to reduce slightly.
- Create Cream Sauce: Reduce heat to low. Gradually whisk in 2 cups (480ml) of heavy cream (or whipping cream) until fully incorporated and smooth. Increase heat to medium-low. Bring the sauce to a very gentle simmer, cooking for 5-7 minutes, stirring occasionally, until it thickens slightly to a coating consistency. Do not bring to a rapid boil.
- Add Cheese and Spinach: Stir in 0.5 cup (50g) of freshly grated Parmesan cheese until melted and smooth. If using, add 2 cups (60g) of fresh spinach. Cook for 2-3 minutes, stirring, until the spinach wilts completely.
- Combine and Finish: Return the cooked chicken to the skillet with the sauce. Add the drained penne pasta. Toss everything gently until the pasta and chicken are evenly coated with the creamy sauce. If the sauce is too thick, add 1-2 tablespoons (15-30ml) of the reserved pasta water until desired consistency is reached. Cook for 1-2 minutes, stirring gently, allowing the flavors to meld and the pasta to heat through.
- Serve: Garnish with 0.25 cup (15g) of fresh chopped parsley and additional freshly grated Parmesan cheese. Serve immediately.
Notes
- Spice Level: Adjust Cajun seasoning for desired spice level. For milder heat, use less; for increased heat, add 0.25 teaspoon (0.6g) cayenne pepper with the Cajun seasoning in Step 1.
- Pasta Alternatives: Penne pasta is recommended. Substitute with fettuccine, linguine, or rigatoni. Cook any pasta until al dente (firm to the bite).
- Make Ahead: Prepare sauce up to 2 days in advance; store in an airtight container in the refrigerator. Reheat gently on the stovetop. If sauce thickens, add 1-2 tablespoons (15-30ml) chicken broth or heavy cream. Combine with freshly cooked pasta and chicken.
- Vegetable Variations: Incorporate other vegetables such as sliced mushrooms, zucchini, or alternative bell pepper colors. Dice or slice vegetables to ensure even cooking.
Pro Tips for Perfect Creamy Cajun Chicken Pasta
Ingredient Tips
- Chicken Preparation:Slice two 6-ounce chicken breasts horizontally into 1/2-inch thick cutlets or 1-inch cubes for uniform cooking. Sear quickly, 3-4 minutes per side, developing a rich, golden-brown crust.
- Cajun Seasoning Application:Use 2-3 tablespoons of quality Cajun seasoning. Toss 1.5 tablespoons with chicken. Add remaining 0.5-1.5 tablespoons to sautéed vegetables for 30 seconds to bloom spices, building layered depth.
- Aromatic Vegetables:Dice 1 medium yellow onion and 1 red bell pepper into 1/4-inch pieces. Sauté in 1 tablespoon olive oil over medium heat for 5-7 minutes until fork-tender and translucent, melting into the sauce.
- Pasta Choice & Cooking:Choose 12 ounces of short, ridged pasta (penne or rotini) for sauce trapping. Cook 1-2 minutes LESS than package directions to a firm al dente. Reserve 1 cup starchy pasta water for consistency.
Technique Tips
- Searing the Chicken:Heat 1 tablespoon oil in a large skillet over medium-high until shimmering (approx. 375°F). Sear seasoned chicken 3-4 minutes per side until deeply golden-brown and 160°F internal. Rest 5 minutes to keep juices.
- Deglazing the Pan:After chicken/aromatics, pour in 1/2 cup chicken broth. Scrape pan vigorously for 1-2 minutes, dissolving all browned bits (fond). This adds crucial savory depth to your sauce.
- Building the Cream Sauce:Reduce heat to medium-low. Whisk in 1.5 cups full-fat heavy cream and 1 cup grated Parmesan. Simmer gently 5-7 minutes, stirring, until sauce visibly thickens and coats a spoon, creating velvety texture.
- Combining Pasta and Sauce:Transfer al dente pasta directly into simmering sauce. Toss continuously 1-2 minutes, letting pasta absorb flavors. If too thick, add reserved pasta water, 1/4 cup at a time, until glossy and slides off tongs.
Common Issues
- Sauce is Too Thin:If sauce isn’t thickening after 7-8 minutes, make a slurry: 1 tablespoon cornstarch with 2 tablespoons cold water. Whisk into simmering sauce; cook 1-2 minutes until desired creamy consistency, clinging to pasta.
- Sauce is Too Thick/Clumpy:If sauce is overly thick/clumpy, gradually whisk in reserved hot pasta water, 1/4 cup at a time. Aim for consistency that evenly coats each pasta strand and appears glossy, not dense.
- Chicken is Dry or Tough:Slice dry chicken thinly (1/8-inch) against grain. Toss gently into warm sauce just before serving; moisture will rehydrate it. For future, don’t exceed 165°F internal temp and rest for 5 minutes.
- Lack of Flavor Depth:If flat, stir in 1/2 teaspoon additional Cajun seasoning, 1/4 teaspoon smoked paprika, and 1 teaspoon Worcestershire sauce for 2-3 minutes. A final 1 tablespoon fresh lemon juice brightens flavors considerably.
Storing and Reheating Creamy Cajun Chicken Pasta
Ensuring your leftover Creamy Cajun Chicken Pasta remains delicious is key to enjoying this rich, spicy dish more than once. Proper storage and reheating techniques are vital for maintaining its creamy texture and vibrant flavors.
Refrigerator Storage
Duration: 3-4 days in an airtight container
To preserve optimal quality, transfer cooled Creamy Cajun Chicken Pasta into an airtight glass container or a high-quality BPA-free plastic container as soon as it has cooled sufficiently (within two hours of cooking). Storing in glass often helps prevent flavor absorption by the container. Over time, the pasta will absorb more of the sauce, making the dish thicker and the pasta softer. The chicken may also dry out slightly. While the Cajun spices continue to meld and deepen, the overall creaminess and initial brightness of the dish tend to decline after day 3, with pasta potentially becoming mushier and the sauce losing its fresh consistency.
Freezer Storage
Duration: 2-3 months
Creamy Cajun Chicken Pasta freezes reasonably well, though expect some texture changes. For best results, allow the pasta to cool completely. Portion into individual, airtight freezer-safe containers or heavy-duty freezer bags, pressing out as much air as possible to prevent freezer burn. Thawing instructions: Transfer the frozen pasta to the refrigerator and allow it to thaw completely overnight, typically 10-12 hours. Upon thawing and reheating, the creamy sauce may exhibit slight separation or become a bit grainy; adding a splash of chicken broth, milk, or heavy cream during reheating can help restore its consistency. The pasta will inevitably be softer than freshly cooked, and the chicken might be marginally drier, but the flavors remain robust.
Reheating Instructions
- Stovetop (Recommended):Transfer the desired portion to a non-stick skillet or saucepan. Add 2-4 tablespoons of chicken broth, milk, or heavy cream per serving to rehydrate the sauce. Heat over medium-low heat, stirring frequently, for 5-8 minutes until warmed through and the sauce is creamy again, taking care not to boil. This method is the preferred option for best results, as it gently warms the pasta and allows for easy restoration of the sauce’s texture.
- Oven (Good for Larger Batches):Preheat oven to 350°F (175°C). Place the pasta in an oven-safe dish. Add 1/4 – 1/2 cup of chicken broth or heavy cream to the dish, then cover it tightly with aluminum foil. Bake for 15-20 minutes. Remove the foil, stir gently, and continue baking uncovered for another 5-10 minutes, or until the pasta is bubbling around the edges and thoroughly heated. This method is excellent for preventing dryness but takes longer.
- Microwave (Quickest):Place a single serving in a microwave-safe bowl. Add 1-2 tablespoons of chicken broth or milk to help with rehydration. Cover loosely with a lid or damp paper towel. Heat on medium power (70%) for 1-2 minutes, stir well, then continue heating in 30-60 second intervals until heated through and steaming. The microwave is the fastest option, but it can sometimes dry out the chicken and make the pasta rubbery if overcooked, and the sauce may separate more noticeably.
Make-Ahead Tips
To streamline preparation, certain components of Creamy Cajun Chicken Pasta can be prepped in advance. The cooked chicken can be prepared and shredded or cubed up to 2-3 days ahead of time and stored in an airtight container in the refrigerator. The dry Cajun seasoning blend can be mixed weeks in advance and kept in an airtight spice jar. While fresh pasta is always recommended, if necessary, you can cook the pasta al dente 1 day prior, rinse it thoroughly with cold water, toss with a touch of olive oil to prevent sticking, and store it in an airtight container in the fridge. The sauce base (excluding cream and cheese) can also be made 1-2 days ahead: sauté your aromatics and spices, add broth, cool, and store in an airtight container. When ready to serve, simply warm the sauce base, combine with freshly cooked or prepped pasta and chicken, then stir in the heavy cream and cheeses until melted and creamy.
