Cajun shrimp Alfredo is a bold and comforting dish that combines the creamy richness of classic Alfredo sauce with the smoky, spicy kick of Cajun seasoning. Juicy shrimp are seared to perfection, then tossed with fettuccine in a luscious, garlicky cream sauce that’s bursting with flavor.
This dish is the perfect balance of heat and creaminess — a Southern-inspired twist on an Italian favorite. It’s quick enough for a weeknight dinner yet impressive enough for entertaining. The combination of tender shrimp, creamy sauce, and perfectly cooked pasta makes every bite unforgettable.
The Essence of Cajun Shrimp Alfredo
Cajun shrimp Alfredo brings together two beloved cuisines — Italian and Southern. The Alfredo sauce, made with butter, cream, and Parmesan, provides a rich, velvety base. The Cajun seasoning adds depth, spice, and a smoky aroma that transforms the dish into something extraordinary.
The shrimp are coated in Cajun spices and seared until golden, infusing the sauce with their flavor. The result is a dish that’s creamy, spicy, and deeply satisfying.
Why This Recipe Works
This recipe works because it layers flavors at every step. The shrimp are seasoned and seared first, creating a flavorful base. The same pan is used to make the sauce, allowing the browned bits to enrich the cream. The Cajun seasoning ties everything together, giving the dish its signature warmth and complexity.
The balance of spice, cream, and cheese ensures that the dish is bold but not overwhelming. The sauce clings perfectly to the pasta, creating a luxurious texture in every bite.

Step-by-Step Recipe
Ingredients
- 12 ounces (340 g) fettuccine
- 1 pound (450 g) large shrimp, peeled and deveined
- 2 tablespoons Cajun seasoning
- 2 tablespoons olive oil
- 3 tablespoons unsalted butter
- 4 cloves garlic, minced
- 1 ½ cups heavy cream
- 1 cup freshly grated Parmesan cheese
- Salt and black pepper, to taste
- 2 tablespoons chopped parsley
- 1 tablespoon lemon juice (optional)
Preparation
- Cook the pasta. Bring a large pot of salted water to a boil. Cook the fettuccine according to package instructions until al dente. Reserve ½ cup of pasta water, then drain.
- Season the shrimp. Pat the shrimp dry and toss with Cajun seasoning until evenly coated.
- Sear the shrimp. In a large skillet, heat olive oil and 1 tablespoon of butter over medium-high heat. Add the shrimp in a single layer and cook for 1–2 minutes per side, until pink and opaque. Remove from the pan and set aside.
- Make the sauce. In the same skillet, melt the remaining butter. Add the minced garlic and cook for 30 seconds until fragrant.
- Add the cream. Pour in the heavy cream and bring to a gentle simmer. Reduce the heat to medium-low and stir in the Parmesan cheese until melted and smooth.
- Season the sauce. Add salt, pepper, and a pinch of Cajun seasoning to taste.
- Combine everything. Add the cooked pasta and shrimp to the sauce. Toss to coat evenly, adding a splash of reserved pasta water if needed to loosen the sauce.
- Finish and serve. Sprinkle with chopped parsley and a squeeze of lemon juice. Serve immediately.

The Science of Creamy Alfredo Sauce
The creaminess of Alfredo sauce comes from the emulsion of butter, cream, and cheese. The fat in the butter and cream blends with the starch from the pasta water, creating a smooth, cohesive sauce. Parmesan adds umami and thickness, while the Cajun seasoning infuses the sauce with spice and color.
The key is to heat the sauce gently and stir constantly to prevent separation. The result is a silky, rich sauce that coats the pasta perfectly.

For an elegant presentation, twirl the fettuccine into nests on each plate and top with shrimp. Drizzle with extra sauce and sprinkle with parsley and Parmesan.
For a rustic look, serve directly from the skillet with lemon wedges on the side. The golden shrimp and creamy sauce make this dish visually stunning.
