Quick answer
Rub chicken strips with cajun seasoning and sear 4 to 5 minutes per side until blackened. Simmer penne in chicken broth about 11 minutes until tender, stir in cream and parmesan for the sauce, then slice the chicken over the top and finish with sliced scallions. Each serving carries about 32 g of protein from label values across 4 servings.
Cajun Chicken Pasta is the weeknight dinner that tastes like a restaurant plate but cooks in one pan. It is juicy strips of chicken rubbed in smoky cajun seasoning and seared until blackened, tossed with penne that simmered right in chicken broth, and finished in a creamy parmesan sauce with sweet bell pepper and onion. Bold, creamy and on the table in about 35 minutes.
Why you’ll love it
- One pan from start to finish, so dinner and cleanup both stay simple.
- The chicken sears blackened and juicy, carrying all the smoky cajun flavor.
- Simmering the penne in broth instead of water builds a silkier, deeper sauce.
- About 32 g of protein per serving from label values, so it eats like a full meal.
- Easy to dial the heat up or down, mild for kids or fiery for spice lovers.
Ingredient notes
Cajun seasoning: the flavor backbone of the whole dish. A good blend brings paprika, garlic, onion, thyme and cayenne in balance. Store bought works great, but check the salt level, since some brands are very salty and you will want to ease back on the added salt.
Chicken breasts: cut into even 1/2 inch strips so they sear fast and stay juicy. Even thickness matters more than the cut itself, thin ends overcook while thick centers stay raw. Thighs are a fine swap if you prefer darker meat.
Penne: the sturdy shape that holds up to simmering in broth and grabs the creamy sauce in its tubes. Short shapes with ridges or hollows catch more sauce than smooth long noodles, which is why penne beats spaghetti here.
Heavy cream and parmesan: the sauce duo. Cream gives body and richness, parmesan gives salty depth and helps the sauce cling to the pasta. Grate the parmesan fresh from a wedge, since pre shredded cheese carries starch that can make the sauce grainy.
Bell pepper and onion: the sweet counterpoint to the smoky heat. They soften right in the same pan and pick up the browned chicken flavor from the bottom, so nothing goes to waste.
The sear and simmer rule that makes or breaks it
Two rules decide this pasta, and both are about heat control. First, the pan must be properly hot before the chicken goes in, and the strips must sit in a single uncrowded layer. That hard sear is what blackens the seasoning into a crisp, smoky crust instead of steaming it into a soggy coating. Second, once the cream and parmesan go in, the heat comes down. A gentle simmer melts the cheese into a silky sauce, while a rolling boil breaks it into a grainy mess. Hot pan for the chicken, gentle heat for the sauce, and the dish practically makes itself.
Variations
- Shrimp swap: replace the chicken with large shrimp, seared 2 minutes per side. It is a natural cajun pairing and cooks even faster.
- Extra veggie: stir in a handful of baby spinach or sliced mushrooms with the bell pepper for a more loaded pan.
- Lightened up: use half and half instead of cream and chicken thighs instead of breasts for a sauce that is a little lighter but still rich.
- Baked finish: transfer the finished pasta to a baking dish, top with extra parmesan and broil 2 minutes for a golden, bubbly crust.
What we learned testing it
- The broth simmer test won clearly. Cooking the penne directly in chicken broth instead of water gave a deeper flavored sauce and a silkier finish, since the pasta starch stayed in the pan.
- Two batches of chicken beat one crowded pan every time. The single layer batches came out blackened and juicy, while the crowded test batch steamed pale and never crisped.

Instructions
-
Season and sear the cajun chicken strips
Pat the chicken strips dry and rub them all over with the cajun seasoning until every strip is evenly coated. Heat the olive oil in a large deep skillet over medium high heat until it shimmers. Sear the chicken in a single layer for 4 to 5 minutes per side, without crowding the pan, until the outside is blackened in spots and the centers are cooked through. Transfer to a plate and tent loosely with foil while you build the sauce.
-
Simmer the penne in chicken broth
Add the butter to the same skillet, letting it pick up the browned bits from the chicken. Stir in the onion and bell pepper and cook 3 to 4 minutes until softened, then add the garlic for the last 30 seconds. Pour in the chicken broth, scraping up any stuck bits, and bring to a boil. Add the penne, reduce to a steady simmer and cook about 11 minutes, stirring often, until the pasta is tender and most of the broth is absorbed.
-
Stir in the cream and parmesan for the sauce
Lower the heat and pour in the heavy cream, stirring to combine. Sprinkle in the parmesan a handful at a time, stirring until each addition melts before adding more. Let the sauce simmer gently 2 to 3 minutes until it thickens enough to coat the back of a spoon. Season with the salt and black pepper, tasting and adjusting the cajun heat with an extra pinch of seasoning if you like it spicier.
-
Slice the chicken and serve over the pasta
Slice the rested chicken strips on a slight diagonal into bite sized pieces. Pile the creamy penne into warm bowls and arrange the sliced blackened chicken over the top. Finish with the sliced scallions, chopped parsley and an extra snowfall of parmesan. Serve right away, while the sauce is glossy and the chicken is still juicy.
Notes
- Pat the chicken dry before seasoning. Dry chicken sears instead of steaming, which is what builds the blackened crust that flavors the whole dish.
- Sear in a single uncrowded layer. If the strips touch, they steam and the seasoning turns soggy instead of crisp. Work in two batches if your skillet is small.
- Stir the penne often while it simmers in broth. The starch is what thickens the sauce later, and pasta left sitting sticks to the bottom of the pan fast.
- Add the parmesan off the boil. If the sauce is bubbling hard when the cheese goes in, it can turn grainy instead of silky.
- These protein estimates come from nutrition labels, not lab testing. A serving lands near 32 g of protein from typical brand labels, mostly from the chicken, parmesan and cream, so check your labels for your exact numbers.

Substitutions
- Chicken breasts
- Use boneless skinless chicken thighs instead. They stay juicier and forgive a little overcooking, just add 1 to 2 minutes to the sear time.
- Heavy cream
- Use half and half for a lighter sauce. It will be a touch thinner, so simmer it 2 minutes longer before adding the parmesan.
- Penne
- Use fettuccine, rigatoni or any short sturdy pasta. Keep the broth amount the same and start checking for tenderness at 10 minutes.
Storage and make-ahead
Leftovers keep in an airtight container in the fridge for up to 3 days. Reheat gently in a skillet over low heat with a splash of chicken broth or cream to loosen the sauce, since it thickens as it sits. The chicken reheats best sliced thin so it warms through without drying out. This pasta does not freeze well, the cream sauce separates when thawed.
Frequently asked questions
How spicy is cajun chicken pasta?
It has a warm, smoky heat that most people call medium. Two tablespoons of cajun seasoning across 4 servings gives flavor first and heat second. For a milder version, use 1 tablespoon of seasoning and add the rest at the table. For more kick, add a pinch of cayenne to the sauce.
Can I use a different pasta shape?
Yes. Any short, sturdy shape works, like rigatoni, ziti or farfalle. Long shapes like fettuccine work too. Keep the broth amount the same and start checking for tenderness a minute or two early, since shapes cook at slightly different speeds.
Can I make cajun chicken pasta without cream?
You can use half and half for a lighter sauce, though it will be a little thinner. For a dairy free version, use an unsweetened oat based cooking cream and a dairy free parmesan style cheese, keeping the heat low so the sauce stays smooth.
Why is my sauce grainy?
Grainy sauce almost always comes from adding parmesan while the liquid is boiling hard. Lower the heat first, add the cheese a handful at a time, and stir until each handful melts. Freshly grated parmesan also melts far smoother than the pre shredded kind.
Can I prep parts of this ahead?
Yes. Slice and season the chicken up to a day ahead and keep it covered in the fridge. You can also dice the onion and slice the pepper a day ahead. Cook the pasta fresh though, since reheated pasta drinks up the sauce and turns soft.
