Creamy Cajun chicken and shrimp Alfredo tossed with fettuccine in a rich, spicy parmesan sauce. A restaurant-quality dinner ready in just 40 minutes.

There's a reason Cajun shrimp and chicken Alfredo shows up on so many restaurant menus. It's rich, a little spicy, and endlessly comforting, all at once. This version brings that same magic into your own kitchen, with tender bites of blackened chicken and juicy shrimp tangled up in a creamy, garlicky parmesan sauce. If you've ever searched for a Cajun shrimp pasta Alfredo recipe that actually delivers restaurant-level flavor without a long ingredient list, this is the one to bookmark.
What makes this dish so satisfying is the contrast. The Cajun seasoning brings smoky heat, while the Alfredo sauce mellows everything out into something silky and indulgent. It's the kind of creamy chicken and shrimp Alfredo that feels special enough for a weekend dinner, but simple enough to make on a random Tuesday.
Before we get cooking, the right tools and ingredients make a real difference here. A good heavy-bottomed skillet helps the sauce reduce evenly without scorching, and freshly grated parmesan melts far more smoothly than the pre-shredded kind. These are the products that genuinely help this recipe shine:
The key to a great shrimp dinner recipe like this one is seasoning every component, not just the sauce. Coating the chicken and shrimp separately in Cajun seasoning before searing means every bite carries that smoky depth, rather than relying on the sauce to do all the work.
Chef's Tip: Sear the chicken and shrimp in batches instead of crowding the pan. This helps them develop a deep golden color instead of steaming, which makes a real difference in the final flavor of your Cajun shrimp and chicken Alfredo.
Searing also leaves behind flavorful browned bits in the skillet, often called fond. That fond becomes the flavor base for the Alfredo sauce, so don't rinse out the pan between steps.
This isn't a jarred alfredo sauce recipe shrimp lovers settle for when they're short on time. It's made from scratch with butter, garlic, heavy cream, chicken broth, and freshly grated parmesan, simmered together until it turns glossy and thick enough to cling to every strand of fettuccine.
A splash of chicken broth alongside the cream keeps the sauce from feeling overly heavy, while still giving you that classic Alfredo richness. Whisking the parmesan in gradually, rather than all at once, is what keeps the sauce smooth instead of clumpy or grainy.

Creamy Cajun chicken and shrimp Alfredo tossed with fettuccine in a rich, spicy parmesan sauce. A restaurant-quality dinner ready in just 40 minutes.
Bring a large pot of salted water to a boil and cook the fettuccine according to package directions until al dente. Drain and set aside, reserving a splash of pasta water.
While the pasta cooks, pat the chicken pieces and shrimp dry with paper towels. Toss the chicken with half the Cajun seasoning and the shrimp with the remaining half.
Heat olive oil in a large, deep skillet over medium-high heat. Add the chicken and cook for 5 to 6 minutes, stirring occasionally, until golden and cooked through. Remove and set aside.
In the same skillet, add the shrimp and cook for 1 to 2 minutes per side until pink and opaque. Remove and set aside with the chicken.
Lower the heat to medium and melt the butter in the skillet. Add the minced garlic and cook for 30 seconds until fragrant.
Pour in the chicken broth and heavy cream, stirring to combine. Bring to a gentle simmer, letting the sauce reduce slightly for 3 to 4 minutes.
Whisk in the parmesan cheese a handful at a time until the sauce is smooth and creamy. Season with salt and black pepper.
Return the chicken and shrimp to the skillet, along with the cooked fettuccine. Toss everything together, adding a splash of reserved pasta water if the sauce needs loosening.
Garnish with fresh parsley and an extra pinch of Cajun seasoning, then serve immediately.
This dish is a complete meal on its own, but a simple side salad or garlic bread rounds it out nicely if you're feeding a hungry table. It also happens to be one of those shrimp recipes for kids that works surprisingly well, since you can easily dial back the Cajun seasoning for younger eaters while keeping the adult portions spicier.
If you're wondering what to cook with chicken tenders on a busy weeknight, this recipe is a great answer, since the tenders cook quickly and stay tender in the sauce. It's also a flexible base for other chicken with Alfredo sauce recipes. Swap in penne or rigatoni if that's what you have on hand, or stir in sauteed mushrooms or spinach for extra texture.
Chef's Tip: If you're meal prepping, keep the pasta and sauce stored separately from the protein. This keeps the shrimp from turning rubbery when reheated and helps the whole dish taste freshly made the next day.
However you serve it, this Cajun chicken and shrimp Alfredo is proof that a truly great weeknight dinner doesn't need to be complicated. Just bold seasoning, a good sear, and a sauce worth savoring.
