Introduction
Bold Cajun spice meets rich, creamy pasta in this creamy Cajun shrimp pasta skillet, and the combination is nothing short of addictive. Shrimp gets coated in a punchy Cajun seasoning, seared until deeply golden, then tossed with fettuccine in a velvety parmesan cream sauce that mellows the heat just enough to keep every bite balanced.
I love this one because it takes two things people already love — spicy Cajun flavor and creamy pasta — and combines them into something that feels like a genuine restaurant dish. The seasoning creates a slightly charred, flavorful crust on the shrimp that contrasts beautifully with the smooth, rich sauce, and the whole thing comes together in about 30 minutes.
Serve it in big bowls with extra parmesan and a side of garlic bread for good measure. However you plate it, this creamy Cajun shrimp pasta recipe turns an ordinary pasta night into something worth talking about.

Ingredient Notes
The Cajun seasoning is a simple mix of smoked paprika, cayenne, garlic powder, onion powder, dried thyme, and dried oregano, and it’s what gives the shrimp its signature bold, smoky heat. A hot, well-seasoned skillet is essential for getting that deeply golden, slightly charred crust on the shrimp in just a couple of minutes per side.
Freshly grated parmesan cheese is essential for a smooth, glossy cream sauce, since the pre-shredded, bagged kind contains anti-caking agents that can leave the sauce grainy instead of silky. Heavy cream creates the sauce’s rich, velvety body, and there isn’t a great low-fat substitute that achieves quite the same texture, so this is one recipe where it’s worth using the real thing.
For the pasta, fettuccine is the classic choice since its wide, flat shape holds onto this rich sauce especially well, though penne or linguine also work if that’s what you have on hand. Reserve some pasta water before draining, since it’s the easiest way to adjust the sauce’s consistency once everything comes together.
🔥 Creamy Cajun Shrimp Pasta Skillet Recipe
Prep Time: 10 minutes | Cook Time: 20 minutes | Total Time: about 30 minutes Servings: 4
Ingredients
For the Pasta:
- 12 oz fettuccine
For the Cajun Seasoning:
- 1 1/2 tsp smoked paprika
- 1/2 tsp garlic powder
- 1/2 tsp onion powder
- 1/2 tsp cayenne pepper (adjust to taste)
- 1/2 tsp dried thyme
- 1/4 tsp dried oregano
- 1/2 tsp salt
- 1/4 tsp black pepper
For the Shrimp:
- 1.5 lbs large shrimp, peeled and deveined
- 1 tbsp olive oil
For the Creamy Sauce:
- 4 tbsp unsalted butter
- 5 cloves garlic, minced
- 1 1/2 cups heavy cream
- 1/2 cup chicken broth
- 1 cup freshly grated parmesan cheese, plus extra for serving
- 1/2 tsp dried Italian seasoning
- 1/4 tsp salt, plus more to taste
- 1/4 tsp black pepper
For Finishing:
- 2 tbsp chopped fresh parsley
- Lemon wedges, for serving
Instructions
Step 1: Cook the pasta. Bring a large pot of salted water to a boil and cook the fettuccine according to package directions until al dente. Reserve about 1/2 cup of pasta water before draining, in case you need to loosen the sauce later.
Step 2: Mix the Cajun seasoning. In a small bowl, combine the smoked paprika, garlic powder, onion powder, cayenne, thyme, oregano, salt, and pepper, stirring well to distribute everything evenly.
Step 3: Season the shrimp. Pat the shrimp completely dry with paper towels, then toss with the olive oil in a large bowl. Sprinkle the Cajun seasoning over the shrimp and toss again until every piece is evenly coated. Tip: pat the shrimp very dry before adding the oil and seasoning — any leftover moisture will prevent the spice coating from sticking and searing properly.
Step 4: Sear the shrimp. Heat a large skillet over medium-high heat until hot. Add the seasoned shrimp in a single layer and cook for about 1–2 minutes per side, until deeply golden with slightly charred edges and just cooked through. Tip: work in batches if your skillet is small — overcrowding drops the pan’s temperature and prevents that dark, blackened crust from forming properly.
Step 5: Remove the shrimp. Transfer the seared shrimp to a plate and set aside. The high heat used for searing should have cooked the shrimp through and created a nicely charred exterior.
Step 6: Build the sauce base. Reduce the heat to medium and add the butter to the same skillet, scraping up any flavorful browned bits left behind from the shrimp. Once melted, add the minced garlic and cook for about 30–60 seconds, stirring constantly, until fragrant.
Step 7: Add the cream and parmesan. Pour in the heavy cream and chicken broth, stirring to combine, and bring to a gentle simmer. Reduce the heat to medium-low, then stir in the grated parmesan a little at a time, mixing well between additions until fully melted and smooth. Season with Italian seasoning, salt, and pepper, and simmer for 3–4 minutes until thickened.
Step 8: Combine and serve. Add the cooked, drained fettuccine to the skillet, tossing gently to coat in the sauce, thinning with reserved pasta water if needed. Divide among bowls, top generously with the Cajun shrimp, and garnish with fresh parsley, extra parmesan, and lemon wedges.
Recipe Notes
- Make sure your kitchen has good ventilation before searing the shrimp — the high heat needed for a good char can produce some smoke, so turn on your exhaust fan if needed.
- Keep the sauce at medium-low heat once the cream and cheese are added — boiling it too vigorously can cause it to break or become grainy.
- Leftover Cajun seasoning keeps well in an airtight container for months and works great on chicken, fish, or steak too.

Storage & Reheating
Leftovers will keep in an airtight container in the fridge for up to 3 days. Reheat gently on the stovetop over low heat, stirring often, and add a splash of milk or cream to loosen the sauce, which tends to thicken significantly once chilled — be careful not to overheat, since the shrimp can turn tough if reheated too aggressively.
This dish isn’t a great candidate for freezing, since cream-based sauces tend to separate once thawed. If you’d like to prep ahead, the cream sauce alone can be made a day in advance and reheated gently before adding freshly cooked pasta and shrimp.
Budget Note
This recipe runs about $6–7 per serving, with shrimp and parmesan being the main cost drivers. To keep it more budget-friendly, buy frozen shrimp in bulk bags rather than fresh from the seafood counter, and make your own Cajun seasoning blend from spices you likely already have rather than buying a premade mix.
Variations
Healthier/Lighter Version: Replace half the heavy cream with additional chicken broth and reduce the butter slightly to lighten the sauce while still keeping it creamy. The Cajun shrimp itself is already fairly light, so this swap mostly trims fat from the sauce.
Keto/Low-Carb Version: This recipe is easy to make low-carb by serving the Cajun shrimp and cream sauce over zucchini noodles or spaghetti squash instead of traditional pasta. The sauce itself is already naturally low-carb as written.
Cajun Chicken Version: Swap the shrimp for sliced, Cajun-seasoned chicken breast for a different protein that follows the same seasoning and searing method. This turns the same beloved sauce into a Cajun chicken pasta instead.
Meal-Prep Friendly: Make a full batch and portion it into containers for easy lunches throughout the week. Reheat gently on the stove or in short microwave bursts, adding a splash of milk to loosen the sauce as needed.
Frequently Asked Questions
Can I make this ahead of time? The cream sauce can be made a day in advance and stored in the fridge, then reheated gently on the stove with a splash of cream or milk before adding freshly cooked pasta and shrimp. It’s best to sear the shrimp fresh, since it loses some of its char and texture when reheated.
Is this dish very spicy? It has a noticeable kick from the cayenne in the Cajun seasoning, but the rich cream sauce helps mellow the heat significantly. You can easily reduce the cayenne if you’d like a milder version, or increase it for extra spice.
Why is my kitchen smoky when I sear the shrimp? Some smoke is normal when searing well-seasoned shrimp over high heat, since that’s what creates the deep, charred crust. Turn on your exhaust fan, crack a window, or consider searing the shrimp outdoors on a portable burner if smoke is a concern.
Can I use frozen shrimp? Yes — just make sure it’s fully thawed and patted very dry before seasoning, since excess moisture will prevent the spice coating from sticking and searing properly. Thaw it overnight in the fridge or under cold running water if you’re short on time.
What should I serve with creamy Cajun shrimp pasta? Garlic bread and a simple green salad are classic pairings that round out the meal nicely, while steamed broccoli or asparagus add a fresh, lighter contrast to the rich sauce. A crisp white wine or a cold beer both pair nicely with the spice.
