This spicy creamy cajun chicken pasta is the ultimate weeknight comfort meal when you crave a burst of flavor without spending all evening at the stove. Juicy chicken gets a quick marinade in bold cajun seasoning then sears beautifully, bringing loads of smoky warmth to every bite. Bell peppers and garlic lend sweetness and aroma, all tossed with pasta in a luxuriously silky tomato cream sauce. Finished with parmesan and a dash of chili flakes, each forkful balances creamy richness with just the right heat. It has become a staple in my home for those nights when everyone wants a meal that feels special but needs to come together fast.
I tried this dish when my kids asked for something “just like at a restaurant” and they now ask for it every week I love seeing how the crowd goes quiet in the best way as everyone digs in
Ingredients
- Olive oil: helps coat and marinate the chicken while also adding flavor to the sear Use a fresh bottle for best results
- Butter: rounds out the sauce and gives a rich base Always pick unsalted to control the dish’s saltiness
- Chicken breast: boneless and skinless offers juicy protein that slices easily Make sure the pieces are similar in thickness to cook evenly
- Rigatoni or your favorite pasta: holds the creamy sauce in every groove Choose a brand that cooks up with some bite
- Cajun seasoning: adds heat and depth You can adjust the amount based on your spice preference Use a homemade blend if you like to balance salt and heat
- Garlic: fresh cloves, finely minced, bring essential aromatic sharpness
- Onion: half a medium onion for sweetness as it cooks down Slice thin for even sautéing
- Red bell pepper: brings sweetness and color Go for a shiny pepper with taut skin
- Tomato sauce or crushed tomatoes: create the base of the sauce Look for one with no added sugar for best flavor
- Heavy cream: makes the sauce silky and decadent Choose a good quality cream for best results
- Pasta water: helps loosen and emulsify the sauce Carry over starchy water from boiling pasta
- Parmesan cheese: freshly grated adds nutty depth and brings the sauce together at the end Avoid pre-shredded if possible for meltiness
- Chili flakes and parsley: optional for a final kick and freshness Use as much or as little as you prefer
Step-by-Step Instructions
- Marinate the Chicken:
- Place the sliced chicken breast in a medium bowl Add olive oil and one tablespoon of cajun seasoning Massage everything together until the chicken is evenly coated and set aside so the flavors can soak in while you prepare the rest
- Cook Pasta and Chicken:
- Bring a large pot of salted water to boil and cook your rigatoni about one minute less than al dente Reserve about one cup of the cooking water While the pasta cooks heat a large skillet over medium heat Add a swirl of olive oil and lay in your marinated chicken Sear each piece for two to three minutes per side until golden and mostly cooked through Remove and let the chicken rest
- Sauté the Aromatics and Bell Peppers:
- In the same skillet melt the butter over medium heat Add sliced onion and minced garlic Stir and cook for about two minutes until fragrant and soft Add in sliced red bell pepper and stir for another two minutes so the pepper softens but keeps some bite
- Simmer the Sauce:
- Stir in the tomato sauce along with heavy cream and half a cup of the reserved pasta water Sprinkle over the remaining half tablespoon of cajun seasoning Let the mixture bubble gently for two to three minutes The sauce should look smooth and start to thicken
- Combine and Finish:
- Add the drained pasta and half of your chicken cut into bite sized pieces Stir everything together and let cook for another one to two minutes until the pasta is perfectly tender Fold in freshly grated parmesan Taste and season with salt as needed
- Serve with Garnish:
- Dish the pasta into bowls Top with the remaining chicken slices and scatter over chili flakes and chopped parsley for a final zing Serve hot and creamy for pure comfort

My favorite part is the parmesan cheese finish It melts right into the sauce and creates this velvety bite that everyone fights over Growing up my sister and I would race to see who could get the cheesiest forkful
Storage Tips
This dish is best enjoyed right after cooking but any leftovers will keep well in an airtight container in the fridge for up to three days When reheating add a splash of cream or milk to loosen up the sauce and stir gently over low heat so the cream stays smooth and does not separate
Ingredient Substitutions
You can swap chicken breast for thigh meat if you want a slightly juicier texture For vegetarians try using cubes of sautéed mushrooms or paneer instead of chicken Half and half or a blend of milk and a small spoonful of cream cheese can replace heavy cream when you want a lighter option

Serving Suggestions
I love to serve this pasta with plenty of crusty bread to scoop up any extra sauce Though it is filling on its own a side of simple greens or even roasted broccoli makes a bright counterpoint If you like add an extra swirl of olive oil and more parmesan on top
Cultural and Historical Context
Cajun flavoring comes from Louisiana’s rich tradition of bold spices smoky peppers and a love of hearty one pan meals This dish is a modern twist marrying classic Southern US spices with Italian-style creamy pasta and you feel the warmth and joy of both cuisines in every mouthful
