Most pasta dishes ask you to pick one thing — a sauce, a protein, a vegetable. This one says yes to all of it, and somehow it works.
Cajun chicken pasta is the kind of dish that fills the kitchen with a smell that gets people into the room before you’ve even called them. The chicken gets a quick hard sear, the peppers and onion go in over high heat until they’re deeply colored, and then a sauce of white wine, chicken broth, and heavy cream ties everything together. It’s bold, it’s a little spicy, and it comes together in one skillet.
This makes about 4 servings.
What Makes This Recipe Work
A lot of pasta dishes simmer quietly. This one runs hot from start to finish — at least until the cream goes in. That high heat on the chicken and vegetables isn’t just about speed. It builds color on the meat and gets the peppers and onion charred at the edges, which gives the finished dish a depth that a gentle sauté wouldn’t produce. Don’t be tempted to turn the heat down during those steps.
The other thing worth knowing: the sauce is supposed to be spicy. Cajun seasoning carries the base heat, but you’ll also be adjusting with cayenne and black pepper at the end. Taste as you go and don’t be shy about it.

- 1 tablespoon Cajun seasoning, divided
- 2 tablespoons olive oil, divided

- 1 red bell pepper, seeded and sliced
- ½ red onion, peeled and thinly sliced
- 3 cloves garlic, finely chopped
- Kosher salt, to taste

How to Make It
Cook the pasta first. Follow the package directions but pull the fettuccine while it still has a little bite — al dente, not soft. It will finish cooking when it gets tossed with the hot sauce. Drain it and set it aside.
Season and sear the chicken. Toss the chicken pieces with 1½ teaspoons of the Cajun seasoning until evenly coated. Heat 1 tablespoon of olive oil and 1 tablespoon of butter in a heavy skillet over high heat. Add half the chicken in a single layer and leave it alone for about a minute — let it brown on that first side without stirring. Flip and cook another minute on the other side. Use a slotted spoon to move the cooked chicken to a clean plate. Repeat with the remaining pieces. Keep the pan on high heat when you’re done.
Cook the vegetables hard and fast. Add the remaining tablespoon of olive oil and tablespoon of butter to the hot pan. When the butter melts, add the peppers, onion, and garlic. Sprinkle the remaining 1½ teaspoons of Cajun seasoning over the top and season with salt if you feel it needs it. Cook over high heat for about 1 minute, stirring just enough to keep things moving while still letting the vegetables pick up some dark color. You want them a little charred — that’s intentional. Add the tomatoes, cook for 30 seconds, then pull everything out of the pan and set it aside with the chicken.
Build the sauce. With the pan still over high heat, pour in the wine and chicken broth. Let it cook hard for 3 to 5 minutes, scraping up all the browned bits stuck to the bottom — that’s where the flavor is. Once the liquid has reduced slightly, lower the heat to medium-low and pour in the cream, stirring steadily as it goes in. Let the sauce cook at medium-low until it starts to thicken, a few minutes. Taste it now. Add black pepper, cayenne, and salt until it’s where you want it. It should have real heat behind it.
Bring everything together. Add the chicken back to the sauce along with all the juices that collected on the plate — don’t skip that step, those juices carry flavor. Add the vegetables too. Stir and let the whole thing cook until it’s bubbling and hot, about 1 to 2 minutes. Add the drained pasta and toss until every strand is coated.
Scatter chopped fresh parsley over the top before serving.
Where Things Can Go Wrong
The chicken turns out dry. This happens when the pieces are too crowded in the pan. Crowding traps steam and braises the chicken instead of searing it. Cook in two batches and give each piece room.
The sauce is thin. It needs time at medium-low heat to thicken. If it’s still loose after a few minutes, keep cooking and stirring before you add the pasta. Adding pasta to a thin sauce just makes it thinner.
The vegetables are soft instead of charred. Same issue as the chicken — too much in the pan at once, or the heat wasn’t high enough. Use a large, heavy skillet and don’t stir too often. You want some dark spots on those peppers.
Substitutions and Adjustments
The white wine adds brightness and helps deglaze the pan. If you’d rather skip it, use an equal amount of additional chicken broth with a small squeeze of lemon juice. It’s not identical, but it works.
For heat level, the cayenne at the end gives you real control. Start conservative, taste, and keep adding until it’s right for your table. The dish should have a kick, but how much is up to you.
If you want to swap the protein, this same technique works well with shrimp. Cut the sear time down significantly — shrimp cook fast, and they’ll finish in the sauce anyway.
Storage and Reheating
Store leftovers in a sealed container in the fridge for up to three days. Reheat gently on the stovetop over medium-low heat with a splash of chicken broth or cream to bring the sauce back to life. The microwave works in a pinch, but the sauce can separate if it heats too quickly.
This one doesn’t freeze particularly well. The cream sauce tends to break when thawed and the pasta texture suffers. Better to make it fresh.
FAQ
Can I use a different pasta shape?
Fettuccine works well because the wide noodles hold onto the sauce, but penne or rigatoni are solid alternatives. Avoid very thin pasta — it can get overwhelmed by everything else in the pan.
My sauce tastes flat. What happened?
A few possibilities: under-seasoned pasta water, not enough salt in the sauce, or the Cajun seasoning you used was mild. Taste the sauce before adding the pasta and season aggressively at that stage. You can always add more, but you can’t take it back.
Can I make this ahead of time?
The individual components — seared chicken, cooked vegetables, even the sauce — can be made a few hours ahead and stored separately. Combine and reheat gently just before serving. Fully assembled and refrigerated overnight, it reheats reasonably well with a little added liquid.
How do I know the chicken is cooked through?
After the initial sear, the pieces will finish cooking when you add them back to the sauce. By the time the whole thing is bubbling and hot, they’ll be done. If you’re unsure, cut one open — it should be white all the way through with no pink.

Ingredients
Method
- Cook pasta according to package directions. Drain when pasta is still al dente; do not overcook!
- Sprinkle 1 1/2 teaspoons of the Cajun seasoning over the chicken pieces. Toss to coat.
- In a heavy skillet, heat 1 tablespoon of the oil and 1 tablespoon butter over high heat. Add half of the chicken in a single layer; do not stir. Allow the chicken to brown on one side, about 1 minute. Flip to the other side and cook for an additional minute. Using a slotted spoon, remove the chicken to a clean plate. Repeat with the remaining chicken. Remove the chicken, leaving the pan on high heat.
- Add the remaining 1 tablespoon of olive oil and 1 tablespoon of butter to the pan. When heated, add the peppers, onion, and garlic. Sprinkle on the remaining 1 1/2 teaspoons of Cajun seasoning, and season with salt, if needed. Cook over high heat for 1 minute, stirring gently and trying to get the vegetables as dark/black as possible. Add the tomatoes and cook for 30 seconds more. Remove all of the vegetables from the pan.
- With the pan over high heat, pour in the wine and chicken broth. Cook on high for 3 to 5 minutes, scraping the bottom of the pan to deglaze. Reduce the heat to medium-low and pour in the cream, stirring/whisking constantly. Cook the sauce over medium-low heat until the cream starts to thicken the mixture, a few minutes. Taste and add black pepper, cayenne pepper, and salt to taste. The sauce should be spicy!
- Finally, add the chicken and vegetables to the sauce, making sure to include all the juices that have drained onto the plate. Stir and cook until the mixture is bubbly and hot, 1 to 2 minutes. Add the drained pasta and toss to combine.
- Top with chopped fresh parsley and chow down!
