Ingredients Needed
Cajun Shrimp
I’m using most of the same ingredients that I used in my air fryer Cajun shrimp. But, I’m searing the shrimp in the pan.
- Shrimp: I’m using raw, thawed peeled and deveined jumbo shrimp. I prefer to get the kind labeled 16-20 or 13-15 per pound.
- Butter: I’m using regular unsalted butter, but you could also use my 5-minute garlic herb butter
- Cajun Seasoning: this is my homemade seasoning mix that can be used in this recipe, but also stored to make Cajun Shrimp, Air Fryer Cajun Chicken Thighs, Cajun Wings and Keto Shrimp & Grits.
Alfredo Sauce
This sauce comes from my keto Alfredo sauce recipe.
- Butter: I’m using unsalted butter
- Parmesan Cheese: this is the fresh grated kind from the refrigerated section in the market. I have not used the shelf-stable Parmesan cheese in this sauce and do not recommend it as it is often saltier than the refrigerated option.
- Garlic: fresh minced garlic packs the most flavor
- Cream Cheese: this adds to the creamy texture. You can soften this quickly by adding it to the microwave for 15 seconds.
- Italian Seasoning: this gives the dish flavors like oregano, parsley, red crushed peppers, and thyme.
- Heavy Cream: I’m using organic heavy whipping cream.
Cajun Shrimp Pasta Alfredo Base
You can use any base that you prefer.
- Pasta Base: in the tutorial, I’m using hearts of palm noodles as a low-carb pasta base. I’ve also used steamed broccoli and zoodles for a low-carb option.

How to Make Cajun Shrimp Alfredo
The best way to learn how to make this dish is to watch the video tutorial.
Generally, you can make Cajun Shrimp Alfredo by:
- Tossing the shrimp in the Cajun seasoning
- Sear the seasoned shrimp on both sides and set aside
- Add the Alfredo ingredients to the pan and cook until the sauce thickens
- Add shrimp along with steamed broccoli, zoodles or hearts of palm noodles or another base to the sauce before serving
Top Cooking Tips & FAQs
- Use the same pan: you might be tempted to make the Alfredo sauce in a separate pan than the one you use to cook the shrimp, but don’t. The leftover bits and fat from the shrimp can be a great starter for the Alfredo sauce.
- Add more liquid to get a looser sauce: this sauce is thick and creamy. To get a looser sauce, simply add more cream. You could also add broth for a lighter option.
Making Cajun Shrimp Alfredo with Jarred Alfredo Sauce
I love to make my own Alfredo sauce, but you can use your favorite jarred Alfredo sauce to save time.
After cooking the shrimp, simply add the jarred Alfredo sauce to the pan and heat it through.
