Cajun shrimp pasta brings together smoky spice and creamy comfort for a dinner that feels both special and effortless. Juicy shrimp coated in homemade Cajun seasoning get seared until golden, then tossed with tender pasta and a luscious tomato cream sauce. The result satisfies cravings for something bold and indulgent but comes together quickly—perfect for a weeknight or a relaxed evening with friends.
I first made this dish after a long day when I craved something restaurant-worthy at home. The smell of the toasty seasoning and shrimp won over everyone in the kitchen and Cajun shrimp pasta quickly earned a spot in our regular rotation.

Recipe FAQs
- → What type of shrimp works best?
Extra-large, peeled and deveined shrimp work best, as they hold up well to searing and absorb the Cajun spices for maximum flavor.
- → Can I use a different pasta shape?
Yes, linguine and spaghetti work well, but fettuccine or penne are also great for holding the sauce and mixed shrimp.
- → How spicy is this dish?
The heat level is moderate, but you can double the cayenne for extra kick or reduce it for a milder flavor.
- → Can I substitute the cream?
You can use half-and-half or whole milk for a lighter sauce; just note the sauce will be slightly less rich.
- → How do I keep the shrimp tender?
Sear shrimp quickly over medium-high heat, then remove from the pan as soon as they turn opaque and pink to avoid overcooking.
- → Is this dish gluten free?
You can make it gluten free by using gluten-free pasta and a gluten-free flour alternative for the sauce thickener.
