This Cajun Shrimp Alfredo recipe combines juicy cajun shrimp with my easy keto alfredo sauce! I keep it low-carb for everyday meals by enjoying it with steamed broccoli, zoodles or hearts of palm noodles. But, you can also use the shrimp with the creamy alfredo sauce to make any pasta base full of flavor.
Why Make This
- Quick & easy: this creamy shrimp alfredo recipe requires simple ingredients and comes together in about 30 minutes. You can even cook the Cajun shrimp in the air fryer. Enjoy this low carb shrimp alfredo as a quick weeknight meal, quick keto dinner for the weekend, meal prep, or a delicious meal for special occasions that the whole family will love.
- Full flavor option that can cut carbs: This Cajun creamy keto shrimp alfredo recipe is the perfect alternative to traditional shrimp alfredo while keeping all the flavors you love. Try this with regular pasta if you wish or do what I did and pair this with a low carb noodle substitute like hearts of palm noodles or air fryer spaghetti squash.
- Choose any base that you prefer: whether you’re following a keto or low-carb diet, you can tailor this dish to suit the way you eat. The shrimp and homemade alfredo sauce make a good topping to any base that you choose.
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.
- Fresh 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.
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 cloves pack 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 because it is a great option. I’ve also used steamed broccoli and zoodles for a low-carb option. Additionally, you can use this Air Fryer Spaghetti Squash recipe and add your cooked shrimp and alfredo sauce to the spaghetti squash noodles to make Cajun Spaghetti Squash Shrimp Alfredo. Lastly, if you prefer, use palmini noodles or any low carb noodle that is available in grocery stores.
How to Make Cajun Shrimp Alfredo
The best way to learn how to make this low carb alfredo dish is to watch the video tutorial.
Generally, you can make Cajun Shrimp Alfredo by:
- Tossing the raw 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 (zucchini noodles) or hearts of palm noodles or another base to the creamy 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.
- Optional: If you want an extra kick, add a little black pepper, cayenne pepper or red pepper flakes.
Making Cajun Shrimp Alfredo with Jarred Alfredo Sauce
I love to make my own Alfredo sauce, but you can use your favorite jarred Alfredo cream sauce from your local grocery store to save time.
After cooking the shrimp, simply add the jarred Alfredo sauce to the pan and heat it through.
