Pasta is often one of my go-to dinner options when I’m craving something quick, simple and delicious. This creamy Cajun Shrimp Alfredo Spaghetti only takes 30 minutes to make from start to finish. It’s packed with flavor and protein but the list of ingredients is short and simple.
You won’t believe the sauce is made without any butter or heavy cream because it’s so rich and decadent. I use a combination of light (5%) cream and cottage cheese to create a smooth and thick sauce that mimics the texture of any restaurant-style Alfredo. All you need to do is throw a few ingredients into a blender and your sauce is ready.
While you wait for the water to boil then for the pasta to cook, you’ll sear up some Cajun seasoned shrimp (this would be great with chicken, too!). Onions and garlic get sautéed in the same pan and in goes the sauce. A little Parmesan cheese and extra spices give it the final touch then the shrimp and cooked spaghetti go in.
I love to use protein pasta for this recipe. Between the shrimp, cottage cheese, Parmesan and protein pasta, each serving of this easy, delicious dinner packs about 63g of protein. Regular pasta works great here too, and you can use any shape you like!
One important note for this recipe: be careful with the salt. A lot of Cajun seasoning blends already include salt, and the pasta water that keeps the sauce silky is also already seasoned with salt. Wait until the very end to taste test, then add salt a pinch at a time if desired.
