Blackened Steak and Shrimp Alfredo is a rich and flavorful dish that combines blackened seasoned shrimp and top sirloin with a creamy alfredo sauce. It’s like a surf and turf over a bed of creamy pasta! It’s just so good! I also have Blackened Shrimp Cavatappi that you will want to try, too!

Ingredients & Substitutions
Pasta: I like penne pasta for its tubular shape, which holds the creamy Alfredo sauce so well! However, you could certainly use other varieties of pasta or make homemade pasta!
Shrimp: Look for large raw shrimp that have been deveined and the tail removed. If buying fresh shrimp, it’s easy to peel and devein. To peel, start from underneath. To devein, make a slit (not too deep) along the back of the shrimp, pulling out the black vein with the tip of a knife. It is up to you if you leave the tails on or off. (We removed the tails.) Shrimp are fully cooked when their interior is white and the outside is light pink. They will also form a ‘c’ shape when cooked. If using smaller or larger shrimp, adjust the cooking time as needed. You could also use precooked shrimp. Add the seasoning when warming it up.

Steak: I used top sirloin, a relatively tender cut of meat. You could also use your favorite cut of meat like ribeye, New York strip, filet mignon, or tenderloin.
Blackened Seasoning: It’s all about the blackened seasoning when it comes to this dish. It is used to season the shrimp, the steak, and the sauce, making it a triple threat for your taste buds! For the most flavor, make homemade blackened seasoning!
Sauce: The creamy Alfredo sauce is enhanced with blackened seasoning, giving it a smoky and slightly spicy flavor.

Is Blackened Steak and Shrimp Alfredo Spicy?
Because of the blackened seasoning, this dish has a kick. The level of spice can depend on the blackened seasoning you are using. If you are worried about the heat it will bring, start with less seasoning. You can always add more!
