Ingredients
Gathering these simple ingredients sets you up for success with this creamy Cajun pasta recipe.
- Pasta (12 oz, penne or fettuccine) forms the hearty base of this dish. Penne holds the thick cream sauce perfectly inside its tubes. Fettuccine, rigatoni, or linguine all work beautifully. Cook to al dente — the pasta finishes cooking in the sauce and absorbs maximum flavor.
- Chicken breast (1 lb, sliced into strips) provides the lean, satisfying protein. Boneless chicken thighs stay even juicier. Large shrimp (peeled and deveined) substitute perfectly for a seafood version. Andouille sausage is the classic Cajun choice for deep, smoky authenticity.
- Cajun seasoning (2 tbsp) is the soul of this entire recipe. Use a quality store-bought blend or make your own — it typically contains paprika, garlic powder, onion powder, cayenne, oregano, and black pepper. According to Bon Appétit’s guide to Cajun seasoning, the paprika and cayenne combination is what creates that signature orange-tinted, bold-flavored sauce.
- Heavy cream (1 cup) creates the silky, luscious sauce that coats every strand of pasta. Half-and-half works for a lighter version, though the sauce will be slightly thinner. Coconut cream is an excellent dairy-free substitute that adds a subtle sweetness.
- Chicken broth (½ cup) deglazes the pan and adds savory depth to the sauce. Vegetable broth substitutes for a lighter flavor. The starchy pasta cooking water makes an excellent addition too — always reserve a cup before draining.
- Garlic (4 cloves, minced) builds the aromatic foundation of the sauce. Fresh garlic is strongly recommended over powdered here — it blooms in the butter and infuses the cream beautifully. Roasted garlic adds a sweeter, deeper dimension.
- Bell peppers (1 red + 1 green, sliced) add color, crunch, and natural sweetness that balance the heat of the Cajun spice perfectly. The holy trinity of Cajun cooking — bell pepper, onion, and celery — traces back to the heart of Louisiana cuisine.
- Onion (1 medium, diced) forms part of Cajun cooking’s classic flavor base. Yellow onion is traditional. Shallots offer a milder, slightly sweeter alternative.
- Butter (2 tbsp) sears the chicken beautifully and starts the sauce with richness. Olive oil substitutes if needed. Using half butter and half oil raises the smoke point and prevents burning.
- Parmesan cheese (½ cup, freshly grated) finishes the sauce with salty, nutty depth and helps it cling to the pasta. Always grate it fresh — pre-shredded cheese contains anti-caking agents that prevent proper melting.
- Salt, pepper, and red pepper flakes season to perfection. Taste before adding extra salt — Cajun seasoning already contains sodium. Red pepper flakes let each person customize heat at the table.
- Fresh parsley and green onions for garnish. These aren’t optional decoration — they add freshness, color, and brightness that lifts the richness of the cream sauce.

Ingredients (Recipe Card)
Main:
- 12 oz penne or fettuccine pasta
- 1 lb chicken breast, sliced into strips
- 2 tbsp Cajun seasoning
- 2 tbsp butter
- 4 cloves garlic, minced
- 1 medium onion, diced
- 1 red bell pepper, sliced
- 1 green bell pepper, sliced
- ½ cup chicken broth
- 1 cup heavy cream
- ½ cup freshly grated Parmesan
- Salt, black pepper, red pepper flakes to taste
Garnish:
- Fresh parsley, roughly chopped
- Green onions, sliced
- Extra Parmesan for serving
Instructions (Recipe Card)
- Cook pasta in salted boiling water until 1 minute shy of al dente. Reserve 1 cup pasta water before draining. Set aside.
- Season chicken strips generously on all sides with Cajun seasoning, salt, and pepper.
- Melt butter in a large skillet or Dutch oven over medium-high heat. Sear chicken strips for 3–4 minutes per side until golden and cooked through. Remove and set aside.
- In the same pan, sauté onion and bell peppers for 2–3 minutes until slightly softened. Add minced garlic and cook 30 seconds until fragrant.
- Pour in chicken broth and scrape up any browned bits from the bottom of the pan — those bits are pure flavor.
- Reduce heat to medium. Pour in heavy cream, stir to combine, and let it simmer for 2 minutes.
- Add drained pasta to the sauce. Toss to coat, adding reserved pasta water a splash at a time until the sauce reaches your desired consistency.
- Stir in Parmesan cheese until fully melted and glossy. Return chicken strips to the pan and toss everything together.
- Taste and adjust seasoning. Serve immediately, garnished with fresh parsley, green onions, and extra Parmesan.
Note: For a shrimp version, add large peeled shrimp in Step 3 — they cook in just 2 minutes per side. For extra smokiness, add 1 tsp smoked paprika to the cream sauce. Never rinse your pasta after draining — the starch helps the sauce adhere.
Instructions
Follow these straightforward steps to create your perfect creamy Cajun pasta every time.
- Boil your pasta in generously salted water. Cook it 1 minute less than the package directions indicate — it will finish cooking in the sauce. Before draining, scoop out 1 full cup of starchy pasta water and set it aside. As BBC Food explains, pasta water is liquid gold — the starch it contains is what makes a cream sauce cling perfectly to every piece.
- Season and prep the chicken. Slice chicken breast into strips and coat generously on all sides with Cajun seasoning, salt, and black pepper. Don’t be shy — the seasoning crust is what creates the gorgeous flavor and golden color on the outside of the chicken.
- Sear the chicken in butter over medium-high heat. Melt butter in a large, heavy-bottomed skillet or Dutch oven. Sear chicken strips for 3–4 minutes per side without moving them — you want a deep, golden-brown crust to develop. Remove the chicken and set aside. It will finish warming through when you return it to the sauce.
- Sauté the vegetables in the same pan. Add diced onion and sliced bell peppers to the pan with all those beautiful browned butter and Cajun bits still in it. Cook for 2–3 minutes until slightly softened. Add minced garlic and cook for 30 seconds just until fragrant — don’t let it burn.
- Deglaze with chicken broth. Pour in the chicken broth and use a wooden spoon to scrape up every browned bit stuck to the bottom of the pan. Those bits — called fond — are packed with concentrated flavor. Getting them into your sauce is one of the most important steps in building a truly deep, complex result.
- Build the cream sauce. Reduce heat to medium and pour in the heavy cream. Stir to combine with the broth and vegetable mixture. Let it simmer gently for 2 minutes until it begins to thicken slightly. Don’t let it boil hard — a gentle simmer is all it needs.
- Add pasta and toss to coat. Add the drained pasta directly into the cream sauce. Toss vigorously to coat every piece. Add reserved pasta water a splash at a time — about 2–4 tablespoons — until the sauce is glossy and clings to the pasta without being soupy.
- Finish with Parmesan and return the chicken. Stir in freshly grated Parmesan cheese until it melts completely into the sauce. Add the seared chicken strips back into the pan and toss everything together until the chicken is coated in the cream sauce.
- Taste, adjust, and serve immediately. Taste the sauce and add salt, black pepper, or extra Cajun seasoning as needed. Serve right away in warm bowls, topped with chopped fresh parsley, sliced green onions, and a heavy handful of extra Parmesan.
Pro Tips for Perfect Creamy Cajun Pasta
- Always save pasta water. This is the single most important pasta tip. The starchy water adjusts sauce consistency without watering down flavor. Set a reminder before you drain.
- Don’t move the chicken while it sears. Letting the chicken sit undisturbed in the hot butter is what creates the golden, caramelized crust. Moving it too early causes sticking and prevents browning.
- Taste your Cajun seasoning first. Different brands vary wildly in sodium and heat levels. Taste before you season and adjust the quantity accordingly. For consistent results, make your own blend — our Homemade Fajita Seasoning guide shows you exactly how.
- Use freshly grated Parmesan only. Pre-shredded Parmesan contains cellulose and anti-caking agents that prevent it from melting smoothly. Grating fresh is the difference between a silky sauce and a grainy one.
- Simmer the cream gently, never boil. High heat causes cream to separate and turn greasy. Keep the sauce at a gentle bubble throughout — this is what keeps it silky and glossy.
- Serve immediately. Cream sauces thicken as they sit. This dish is at its absolute best served hot, straight from the pan. Warm your bowls beforehand for an extra professional touch.
Serving Suggestions and Storage
- Serve with garlic bread. Warm, crusty garlic bread is essential for mopping up every last drop of the creamy Cajun sauce — no bowl should be left behind.
- Add a fresh green salad. A crisp, lightly dressed salad balances the richness of this creamy pasta perfectly. Keep the dressing simple — lemon and olive oil work beautifully here.
- Sprinkle extra red pepper flakes. Let each person customize heat at the table. Red pepper flakes, hot sauce, or a drizzle of chili oil all work brilliantly.
- Store leftovers properly. Transfer cooled creamy Cajun pasta to airtight containers and refrigerate up to 3 days. The sauce will thicken in the fridge — this is normal.
- Reheat with a splash of cream or broth. Warm gently on the stovetop over low heat, adding a splash of heavy cream or chicken broth to loosen the sauce back to its original silky consistency. Microwave on 50% power, stirring every 30 seconds.
- Freezing note. Cream-based pasta sauces do not freeze well — the cream separates upon thawing. This dish is best enjoyed fresh or within the refrigerator storage window.

Frequently Asked Questions
Can I make this creamy Cajun pasta recipe with shrimp instead of chicken?
Absolutely — shrimp is one of the most popular variations and arguably the most authentic to Cajun cooking. Use large, peeled, deveined shrimp. Season them the same way as the chicken and sear for just 2 minutes per side until pink. Overcooked shrimp become rubbery, so watch them closely. Love shrimp dishes?

How do I make this less spicy?
Reduce the Cajun seasoning to 1 tablespoon and omit the red pepper flakes entirely. Use a mild or low-heat Cajun blend. The cream naturally mellows the heat — the more cream you use, the milder the result. You can always serve extra hot sauce on the side for those who want more fire.
Can I use a different pasta shape?
Yes — any pasta shape works well with this thick cream sauce. Penne and rigatoni are ideal because they trap sauce inside their tubes. Fettuccine and linguine coat beautifully. Bow tie (farfalle) works perfectly for a fun presentation. For a heartier version, try our One Pot Green Chile Mac and Cheese using a similar one-pot technique.
Can I make this Cajun pasta dairy-free?
Substitute full-fat coconut cream for the heavy cream — it provides the same richness and emulsifies beautifully with the starchy pasta water. Replace the Parmesan with 3 tablespoons of nutritional yeast for a cheesy, savory depth without dairy. Use a plant-based butter like vegan butter sticks to start the sauce.
Why is my cream sauce separating?
Heat is almost always the culprit. Cream separates when brought to a rapid boil or shocked with a sudden temperature change. Keep the sauce at a gentle simmer throughout — never let it boil hard. Adding the pasta water gradually while tossing also helps maintain the emulsion.
