Cajun Shrimp Pasta Ingredients
- Pasta: You can use homemade pasta, fresh pasta or any dry pasta, I love using fettucini or spaghetti but short noodles like penne work well.
- Shrimp: I always keep large frozen shrimp in my freezer. For convenience, buy peeled and deveined shrimp. Fresh shrimp or prawns can be used. Any size of shrimp works well.
- Olive Oil
- Butter: Unsalted or salted
- Cajun Seasoning: You can add a bit extra to make your shrimp pasta a bit spicy.
- Heavy Cream: You can also use Half and Half.
- Parmesan Cheese: Freshly grated is always best.
- Garlic Powder and Ground Black Pepper
- Green Onions and Chopped Parsley: Both optional but a great addition.
How To Make Creamy Cajun Shrimp Pasta
- Boil the pasta in salted water until al dente.
- While the pasta cooks, season the shrimp with Cajun seasoning.
- Place butter and olive oil in a skillet and cook the shrimp for 1-2 minutes per side.
- Remove the shrimp from the skillet. Add the cream, the garlic powder and ground pepper. Simmer on low heat.
- At this point, your pasta should be about ready. Before draining it, reserve one cup of the pasta cooking water. You will use the pasta water if the sauce gets too thick.
- Add the Parmesan cheese to the sauce and simmer on low heat. The sauce should not boil. If it does it will separate and look oily.
- Add the drained pasta into the skillet followed by the Cajun shrimp. Toss gently and season with additional Cajun seasoning to taste. Top with green onions and chopped parsley (optional).
Choose The Right Cajun Seasoning
Cajun seasoning, the spice blend from the bayou area of Louisiana is made of paprika, cayenne pepper, garlic powder, onion powder and other herbs and spices.
If you use store-bought Cajun seasoning, make sure you purchase a low-salt or no-salt mix to prevent the dish from becoming too salty. You can also make your own mix. Here is my favorite homemade Cajun seasoning recipe.
Cajun Pasta Recipe Tips
- Before draining your pasta, remember to save some cooking water. If your sauce gets too thick or your pasta gets a bit dry, add some pasta water to make it creamy again.
- This Cajun Shrimp Alfredo has a bit of a kick. If you love spicy food, add more Cajun seasoning. Just keep an eye on the salt level of your spice mix.
- Shrimp cooks quickly. When the shrimp turns pink, it is done! If you are not sure if the shrimp is completely cooked through, cut one in half. The inside should be white and no longer translucent.
- You can make this Cajun shrimp pasta with Half & Half or even whole milk, although the consistency will be a bit lighter.
