How to make Cajun Shrimp Alfredo

Detailed instructions and measurements for Cajun Shrimp Alfredo are listed in the recipe card at the bottom of this page.

1. Bring a large pot of salted water to a boil. Once boiling, add your linguine and cook according to the package directions. Reserve 1 cup of the pasta water before draining.
2. While your pasta is cooking, heat a heavy-bottomed skillet over medium and add the avocado oil.
3. Season your shrimp with garlic powder & cajun seasoning. Be sure it is coated on all sides. 
4. Once your oil is heated and shimmering, add your shrimp to the skillet. Don’t overcrowd the skillet and do them in batches if needed. Cook about 2 minutes per side. 
5. Once the shrimp has cooked through, remove it from the skillet and set it aside. 
6. Add the celery, green bell pepper, garlic, and onion to the skillet. Season with salt and pepper. Saute until they are softened and cooked through. 
7. Add butter to the skillet with the vegetables. Mix it around and let it melt. 
8. Once the butter has melted, add in the heavy whipping cream. Mix it to combine and let it heat through. Don’t let it boil. 
9. Once the heavy cream has heated through, add in the cream cheese. Mix to combine and let it melt. 
10. When the cream cheese has melted completely, stir in the parmesan cheese and allow it to melt. 
11. Add the cooked shrimp to the skillet with the alfredo sauce. 
12. Combine the alfredo sauce and the pasta, mixing to combine. As you mix it together, pour in a little of the reserved pasta water as needed to help it combine. 
13. Serve with your favorite garlic bread and a little extra cajun seasoning on top!

Shrimp Alfredo Recipe Tips and FAQ

It’s important to be sure that your shrimp is fully thawed and dry before adding to the skillet. You want them to be able to sear in the oil without water being released. 

Reserving some of the pasta water and adding it to the sauce with the pasta will help the sauce stick to the noodles. 

If you like extra spice, you can add more cajun seasoning to the alfredo and the vegetables.
