Creamy Cajun Shrimp Pasta is a rich, spicy, restaurant-worthy dinner ready in 30 minutes, with juicy blackened shrimp tossed in a velvety Parmesan cream sauce.

There is something magical about the moment blackened shrimp hits a bubbling Cajun cream sauce. The kitchen fills with smoky, garlicky steam, and suddenly a Tuesday night feels like a night out. This Creamy Cajun Shrimp Pasta is one of those recipes that looks and tastes far more impressive than the effort it actually takes. Juicy, spiced shrimp meet a silky Parmesan cream sauce studded with sun-dried tomatoes, all tangled up in tender penne.
If you love bold, comforting pasta dinners, this one is about to become a regular in your rotation. It comes together in about 30 minutes, using one skillet for the sauce, which means less cleanup and more time actually enjoying dinner.
Before we get cooking, the right tools and ingredients make a real difference here. A good non-stick or stainless skillet helps you get a proper sear on the shrimp without them sticking or overcooking, and a quality Cajun seasoning blend (or fresh Parmesan you grate yourself) genuinely elevates the final dish. These are the products that genuinely help this recipe shine:
The secret to a great shrimp pasta is layering flavor at every stage rather than dumping it all in at once. The shrimp gets seasoned and seared first, so it picks up a little char and smoky depth. Then the same pan builds the sauce, meaning all those browned bits and residual spice work their way into the cream. By the time the Parmesan melts in, you have a sauce that tastes like it simmered for hours, even though it only took minutes.
Chef's Tip: Do not overcrowd the pan when searing the shrimp. Work in batches if needed. Crowding the skillet steams the shrimp instead of searing it, and you will miss out on that lightly charred, smoky edge that makes this dish special.
This recipe is endlessly flexible too. Swap the penne for rigatoni or fettuccine, add a handful of spinach for color, or turn up the heat with extra cayenne if you like things fiery. It is the kind of weeknight dinner that welcomes a little improvisation.

Creamy Cajun Shrimp Pasta is a rich, spicy, restaurant-worthy dinner ready in 30 minutes, with juicy blackened shrimp tossed in a velvety Parmesan cream sauce.
Bring a large pot of salted water to a boil and cook the penne pasta according to package directions until al dente. Reserve 1 cup of pasta water, then drain and set aside.
While the pasta cooks, pat the shrimp dry with paper towels and toss with 1 tablespoon of the Cajun seasoning until evenly coated.
Heat a large skillet over medium-high heat. Add 1 tablespoon of butter, then sear the shrimp for 1 to 2 minutes per side until pink and slightly charred. Remove shrimp to a plate and set aside.
In the same skillet, melt the remaining butter over medium heat. Add the diced onion and cook for 2 to 3 minutes until softened.
Stir in the garlic and cook for 30 seconds until fragrant.
Sprinkle in the remaining Cajun seasoning and smoked paprika, then pour in the chicken broth, scraping up any browned bits from the bottom of the pan.
Reduce heat to medium-low and stir in the heavy cream. Simmer gently for 3 to 4 minutes until the sauce begins to thicken.
Whisk in the Parmesan cheese until melted and smooth, then fold in the sun-dried tomatoes.
Add the cooked pasta to the skillet and toss to coat, adding reserved pasta water a splash at a time if the sauce needs loosening.
Return the shrimp to the skillet and gently toss to combine, warming through for 1 to 2 minutes.
Season with salt and pepper to taste, garnish with fresh parsley, and serve immediately.
Serve this pasta hot, straight from the skillet, with extra Parmesan and a sprinkle of fresh parsley on top. A simple green salad and warm crusty bread round out the meal nicely, since the bread is perfect for mopping up any leftover sauce.
If you end up with leftovers, they will keep in an airtight container in the fridge for up to three days. Reheat gently on the stovetop over low heat, adding a splash of cream, milk, or broth to loosen the sauce back up. Microwaving works in a pinch, but low and slow on the stove keeps the shrimp from turning rubbery.
However you customize it, this Creamy Cajun Shrimp Pasta is guaranteed to earn a spot on your regular dinner rotation. It is bold, comforting, and proof that a truly satisfying meal does not have to take all night to make.
